Product Description


ROLLER CHAIN

Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission.

LUBRICATION

Many driving chains (for example, in factory equipment, or driving a camshaft inside an internal combustion engine) operate in clean environments, and thus the wearing surfaces (that is, the pins and bushings) are safe from precipitation and airborne grit, many even in a sealed environment such as an oil bath. Some roller chains are designed to have o-rings built into the space between the outside link plate and the inside roller link plates. Chain manufacturers began to include this feature in 1971 after the application was invented by Joseph Montano while working for Whitney Chain of Hartford, Connecticut. O-rings were included as a way to improve lubrication to the links of power transmission chains, a service that is vitally important to extending their working life. These rubber fixtures form a barrier that holds factory applied lubricating grease inside the pin and bushing wear areas. Further, the rubber o-rings prevent dirt and other contaminants from entering inside the chain linkages, where such particles would otherwise cause significant wear.[citation needed]

There are also many chains that have to operate in dirty conditions, and for size or operational reasons cannot be sealed. Examples include chains on farm equipment, bicycles, and chain saws. These chains will necessarily have relatively high rates of wear, particularly when the operators are prepared to accept more friction, less efficiency, more noise and more frequent replacement as they neglect lubrication and adjustment.

Many oil-based lubricants attract dirt and other particles, eventually forming an CHINAMFG paste that will compound wear on chains. This problem can be circumvented by use of a “dry” PTFE spray, which forms a solid film after application and repels both particles and moisture.

VARIANTS DESIGN

Layout of a roller chain: 1. Outer plate, 2. Inner plate, 3. Pin, 4. Bushing, 5. Roller
If the chain is not being used for a high wear application (for instance if it is just transmitting motion from a hand-operated lever to a control shaft on a machine, or a sliding door on an oven), then 1 of the simpler types of chain may still be used. Conversely, where extra strength but the smooth drive of a smaller pitch is required, the chain may be “siamesed”; instead of just 2 rows of plates on the outer sides of the chain, there may be 3 (“duplex”), 4 (“triplex”), or more rows of plates running parallel, with bushings and rollers between each adjacent pair, and the same number of rows of teeth running in parallel on the sprockets to match. Timing chains on automotive engines, for example, typically have multiple rows of plates called strands.

Roller chain is made in several sizes, the most common American National Standards Institute (ANSI) standards being 40, 50, 60, and 80. The first digit(s) indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers. Thus, a chain with half-inch pitch would be a #40 while a #160 sprocket would have teeth spaced 2 inches apart, etc. Metric pitches are expressed in sixteenths of an inch; thus a metric #8 chain (08B-1) would be equivalent to an ANSI #40. Most roller chain is made from plain carbon or alloy steel, but stainless steel is used in food processing machinery or other places where lubrication is a problem, and nylon or brass are occasionally seen for the same reason.

Roller chain is ordinarily hooked up using a master link (also known as a connecting link), which typically has 1 pin held by a horseshoe clip rather than friction fit, allowing it to be inserted or removed with simple tools. Chain with a removable link or pin is also known as cottered chain, which allows the length of the chain to be adjusted. Half links (also known as offsets) are available and are used to increase the length of the chain by a single roller. Riveted roller chain has the master link (also known as a connecting link) “riveted” or mashed on the ends. These pins are made to be durable and are not removable.

USE

Roller chains are used in low- to mid-speed drives at around 600 to 800 feet per minute; however, at higher speeds, around 2,000 to 3,000 feet per minute, V-belts are normally used due to wear and noise issues.
A bicycle chain is a form of roller chain. Bicycle chains may have a master link, or may require a chain tool for removal and installation. A similar but larger and thus stronger chain is used on most motorcycles although it is sometimes replaced by either a toothed belt or a shaft drive, which offer lower noise level and fewer maintenance requirements.
The great majority of automobile engines use roller chains to drive the camshaft(s). Very high performance engines often use gear drive, and starting in the early 1960s toothed belts were used by some manufacturers.
Chains are also used in forklifts using hydraulic rams as a pulley to raise and lower the carriage; however, these chains are not considered roller chains, but are classified as lift or leaf chains.
Chainsaw cutting chains superficially resemble roller chains but are more closely related to leaf chains. They are driven by projecting drive links which also serve to locate the chain CHINAMFG the bar.

A perhaps unusual use of a pair of motorcycle chains is in the Harrier Jump Jet, where a chain drive from an air motor is used to rotate the movable engine nozzles, allowing them to be pointed downwards for hovering flight, or to the rear for normal CHINAMFG flight, a system known as Thrust vectoring.

WEAR

 

The effect of wear on a roller chain is to increase the pitch (spacing of the links), causing the chain to grow longer. Note that this is due to wear at the pivoting pins and bushes, not from actual stretching of the metal (as does happen to some flexible steel components such as the hand-brake cable of a motor vehicle).

With modern chains it is unusual for a chain (other than that of a bicycle) to wear until it breaks, since a worn chain leads to the rapid onset of wear on the teeth of the sprockets, with ultimate failure being the loss of all the teeth on the sprocket. The sprockets (in particular the smaller of the two) suffer a grinding motion that puts a characteristic hook shape into the driven face of the teeth. (This effect is made worse by a chain improperly tensioned, but is unavoidable no matter what care is taken). The worn teeth (and chain) no longer provides smooth transmission of power and this may become evident from the noise, the vibration or (in car engines using a timing chain) the variation in ignition timing seen with a timing light. Both sprockets and chain should be replaced in these cases, since a new chain on worn sprockets will not last long. However, in less severe cases it may be possible to save the larger of the 2 sprockets, since it is always the smaller 1 that suffers the most wear. Only in very light-weight applications such as a bicycle, or in extreme cases of improper tension, will the chain normally jump off the sprockets.

The lengthening due to wear of a chain is calculated by the following formula:

M = the length of a number of links measured

S = the number of links measured

P = Pitch

In industry, it is usual to monitor the movement of the chain tensioner (whether manual or automatic) or the exact length of a drive chain (one rule of thumb is to replace a roller chain which has elongated 3% on an adjustable drive or 1.5% on a fixed-center drive). A simpler method, particularly suitable for the cycle or motorcycle user, is to attempt to pull the chain away from the larger of the 2 sprockets, whilst ensuring the chain is taut. Any significant movement (e.g. making it possible to see through a gap) probably indicates a chain worn up to and beyond the limit. Sprocket damage will result if the problem is ignored. Sprocket wear cancels this effect, and may mask chain wear.

CHAIN STRENGTH

The most common measure of roller chain’s strength is tensile strength. Tensile strength represents how much load a chain can withstand under a one-time load before breaking. Just as important as tensile strength is a chain’s fatigue strength. The critical factors in a chain’s fatigue strength is the quality of steel used to manufacture the chain, the heat treatment of the chain components, the quality of the pitch hole fabrication of the linkplates, and the type of shot plus the intensity of shot peen coverage on the linkplates. Other factors can include the thickness of the linkplates and the design (contour) of the linkplates. The rule of thumb for roller chain operating on a continuous drive is for the chain load to not exceed a mere 1/6 or 1/9 of the chain’s tensile strength, depending on the type of master links used (press-fit vs. slip-fit)[citation needed]. Roller chains operating on a continuous drive beyond these thresholds can and typically do fail prematurely via linkplate fatigue failure.

The standard minimum ultimate strength of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)2. X-ring and O-Ring chains greatly decrease wear by means of internal lubricants, increasing chain life. The internal lubrication is inserted by means of a vacuum when riveting the chain together.

CHAIN STHangZhouRDS

Standards organizations (such as ANSI and ISO) maintain standards for design, dimensions, and interchangeability of transmission chains. For example, the following Table shows data from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Society of Mechanical Engineers (ASME). See the references[8][9][10] for additional information.

For mnemonic purposes, below is another presentation of key dimensions from the same standard, expressed in fractions of an inch (which was part of the thinking behind the choice of preferred numbers in the ANSI standard):

Pitch (inches) Pitch expressed

12 48 40 516
58 58 50 38
34 68 60 12
1 88 80 58

Notes:
1. The pitch is the distance between roller centers. The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
 A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.

Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.

Roller chains made using ISO standard are sometimes called as isochains.

What are the safety features of car parking chains to prevent accidents and injuries?

Car parking chains are designed with several safety features to prevent accidents and injuries. These features ensure that the chains operate safely and effectively, protecting both vehicles and users. Some common safety features include:

1. Reflective Elements: Many parking chains have reflective coatings or materials to enhance visibility, especially during low-light conditions. This makes the chains more noticeable to drivers and pedestrians, reducing the risk of collisions.

2. Smooth and Even Surface: Parking chains are manufactured with smooth and even surfaces to prevent any sharp edges or protrusions that could cause injuries or damage to vehicles.

3. Clear Signage: Proper signage is placed near the parking chains to inform users of their presence and how to operate them. This helps prevent confusion and misuse.

4. Low Friction: Chains are often lubricated to reduce friction and ensure smooth movement, minimizing the risk of accidents caused by chain jams or abrupt stops.

5. Emergency Access: Parking chains are designed with emergency access in mind. In manual systems, there are quick-release mechanisms to allow easy removal of the chain in emergency situations or to facilitate access for emergency vehicles.

6. Height and Clearance: Proper clearance is maintained to prevent chains from interfering with vehicles or causing damage during entry or exit.

7. Secure Mounting: Parking chains are securely mounted to prevent accidental detachment or falling, especially in retractable systems.

8. Load Capacity: For automatic systems, parking chains are designed to handle the weight of vehicles passing through, ensuring they can safely support the load.

9. Regular Maintenance: Regular inspections and maintenance help identify any safety issues and address them promptly, ensuring the chains remain safe for use.

10. Training and Education: Parking attendants and users should receive proper training on how to operate the parking chains safely and effectively.

By incorporating these safety features and promoting responsible use, car parking chains can effectively prevent accidents and injuries, providing a secure and controlled parking environment for all users.

How do automatic car parking chains work, and what are their advantages over manual systems?

Automatic car parking chains are an advanced version of traditional manual parking chains that offer more convenience and efficiency in controlling vehicle access. Here’s how they work and their advantages over manual systems:

1. Automated Operation: Automatic parking chains are integrated with electronic access control systems, such as keycard readers, RFID (Radio Frequency Identification) tags, or remote-controlled mechanisms. When an authorized vehicle approaches the entrance, the system automatically detects the vehicle’s credentials and raises the chain to allow entry.

2. Enhanced Security: With automated access control, there is a reduced risk of human error, which can be a vulnerability in manual systems. Only vehicles with valid credentials can enter, making it harder for unauthorized vehicles to gain access.

3. Time Efficiency: Automated car parking chains operate swiftly, minimizing waiting times for authorized users. This is particularly advantageous in high-traffic areas where manual control could cause congestion during peak hours.

4. Remote Management: Some automatic parking chains can be remotely controlled, allowing operators to manage access from a central location. This can be especially useful for large parking facilities or when physical attendance is not feasible.

5. Integration with Payment Systems: Automated chains can be connected to payment systems, enabling seamless access for users who have paid the required fees or have valid subscriptions.

6. Scalability: Automatic car parking chains can be easily integrated with other smart parking technologies, like ticketing systems or license plate recognition, to create a comprehensive and efficient parking management solution.

7. Reduced Labor Costs: As the system operates automatically, there is no need for manual attendance, leading to potential cost savings in labor.

8. Remote Monitoring: Some advanced automatic systems come with remote monitoring capabilities, allowing operators to track vehicle movement and access patterns in real-time.

Despite these advantages, automatic car parking chains may require higher upfront investment and ongoing maintenance costs compared to traditional manual systems. The choice between the two largely depends on the specific needs and budget constraints of the parking facility or garage.

Product Description

ROLLER CHAIN

Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission.

CONSTRUCTION OF THE CHAIN

Two different sizes of roller chain, showing construction.
There are 2 types of links alternating in the bush roller chain. The first type is inner links, having 2 inner plates held together by 2 sleeves or bushings CHINAMFG which rotate 2 rollers. Inner links alternate with the second type, the outer links, consisting of 2 outer plates held together by pins passing through the bushings of the inner links. The “bushingless” roller chain is similar in operation though not in construction; instead of separate bushings or sleeves holding the inner plates together, the plate has a tube stamped into it protruding from the hole which serves the same purpose. This has the advantage of removing 1 step in assembly of the chain.

The roller chain design reduces friction compared to simpler designs, resulting in higher efficiency and less wear. The original power transmission chain varieties lacked rollers and bushings, with both the inner and outer plates held by pins which directly contacted the sprocket teeth; however this configuration exhibited extremely rapid wear of both the sprocket teeth, and the plates where they pivoted on the pins. This problem was partially solved by the development of bushed chains, with the pins holding the outer plates passing through bushings or sleeves connecting the inner plates. This distributed the wear over a greater area; however the teeth of the sprockets still wore more rapidly than is desirable, from the sliding friction against the bushings. The addition of rollers surrounding the bushing sleeves of the chain and provided rolling contact with the teeth of the sprockets resulting in excellent resistance to wear of both sprockets and chain as well. There is even very low friction, as long as the chain is sufficiently lubricated. Continuous, clean, lubrication of roller chains is of primary importance for efficient operation as well as correct tensioning.

LUBRICATION

Many driving chains (for example, in factory equipment, or driving a camshaft inside an internal combustion engine) operate in clean environments, and thus the wearing surfaces (that is, the pins and bushings) are safe from precipitation and airborne grit, many even in a sealed environment such as an oil bath.

The lengthening due to wear of a chain is calculated by the following formula:

M = the length of a number of links measured

S = the number of links measured

P = Pitch

In industry, it is usual to monitor the movement of the chain tensioner (whether manual or automatic) or the exact length of a drive chain (one rule of thumb is to replace a roller chain which has elongated 3% on an adjustable drive or 1.5% on a fixed-center drive). A simpler method, particularly suitable for the cycle or motorcycle user, is to attempt to pull the chain away from the larger of the 2 sprockets, whilst ensuring the chain is taut. Any significant movement (e.g. making it possible to see through a gap) probably indicates a chain worn up to and beyond the limit. Sprocket damage will result if the problem is ignored. Sprocket wear cancels this effect, and may mask chain wear.

CHAIN STRENGTH

The most common measure of roller chain’s strength is tensile strength. Tensile strength represents how much load a chain can withstand under a one-time load before breaking. Just as important as tensile strength is a chain’s fatigue strength. The critical factors in a chain’s fatigue strength is the quality of steel used to manufacture the chain, the heat treatment of the chain components, the quality of the pitch hole fabrication of the linkplates, and the type of shot plus the intensity of shot peen coverage on the linkplates. Other factors can include the thickness of the linkplates and the design (contour) of the linkplates. The rule of thumb for roller chain operating on a continuous drive is for the chain load to not exceed a mere 1/6 or 1/9 of the chain’s tensile strength, depending on the type of master links used (press-fit vs. slip-fit)[citation needed]. Roller chains operating on a continuous drive beyond these thresholds can and typically do fail prematurely via linkplate fatigue failure.

The standard minimum ultimate strength of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)2. X-ring and O-Ring chains greatly decrease wear by means of internal lubricants, increasing chain life. The internal lubrication is inserted by means of a vacuum when riveting the chain together.

Standards organizations (such as ANSI and ISO) maintain standards for design, dimensions, and interchangeability of transmission chains. For example, the following Table shows data from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Society of Mechanical Engineers (ASME).

For mnemonic purposes, below is another presentation of key dimensions from the same standard, expressed in fractions of an inch (which was part of the thinking behind the choice of preferred numbers in the ANSI standard):

12 48 40 516
58 58 50 38
34 68 60 12
1 88 80 58

Notes:
1. The pitch is the distance between roller centers. The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
 A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.

Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.

Roller chains made using ISO standard are sometimes called as isochains.

How do car parking chains enhance security and prevent unauthorized access to parking areas?

Car parking chains serve as a physical barrier and play a crucial role in enhancing security and preventing unauthorized access to parking areas. Here’s how they achieve this:

1. Physical Deterrent: The presence of a chain across the entrance acts as a visual deterrent, dissuading unauthorized vehicles from attempting to enter the parking area. It signals that the area is controlled and restricted to authorized personnel only.

2. Controlled Access: Parking chains are manually operated or integrated with electronic access control systems. Only authorized users with the appropriate credentials, such as a key, keycard, or remote control, can raise or lower the chain to gain access.

3. Preventing Tailgating: In manual systems, parking attendants can visually verify each vehicle’s authorization before allowing entry. In automatic systems, the access control technology ensures that only one vehicle is allowed to pass at a time, preventing unauthorized vehicles from tailgating behind an authorized one.

4. Flexible Access Control: Some parking chains can be integrated with electronic access control systems that allow for fine-grained control. This includes time-based access permissions or specific access rights for different user groups, enhancing security measures.

5. Cost-Effective Security: Compared to more advanced access control systems like automated gates or barrier arms, parking chains offer a cost-effective security solution, making them suitable for various parking facilities.

6. Reducing Vehicle Theft: By restricting access to only authorized vehicles, parking chains reduce the risk of theft or unauthorized use of parked vehicles.

7. Minimizing Traffic Violations: Parking chains prevent unauthorized parking, reducing instances of illegal parking or traffic violations within the parking area.

8. Additional Security Measures: Parking chains can be complemented with other security features like surveillance cameras, lighting, and manned security personnel, creating a comprehensive security strategy for the parking facility.

In summary, car parking chains provide a simple yet effective method to control access, enhance security, and prevent unauthorized entry into parking areas, ensuring a safer and more controlled environment for vehicles and users.

Product Description


ROLLER CHAIN

Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission.

LUBRICATION

Many driving chains (for example, in factory equipment, or driving a camshaft inside an internal combustion engine) operate in clean environments, and thus the wearing surfaces (that is, the pins and bushings) are safe from precipitation and airborne grit, many even in a sealed environment such as an oil bath. Some roller chains are designed to have o-rings built into the space between the outside link plate and the inside roller link plates. Chain manufacturers began to include this feature in 1971 after the application was invented by Joseph Montano while working for Whitney Chain of Hartford, Connecticut. O-rings were included as a way to improve lubrication to the links of power transmission chains, a service that is vitally important to extending their working life. These rubber fixtures form a barrier that holds factory applied lubricating grease inside the pin and bushing wear areas. Further, the rubber o-rings prevent dirt and other contaminants from entering inside the chain linkages, where such particles would otherwise cause significant wear.[citation needed]

There are also many chains that have to operate in dirty conditions, and for size or operational reasons cannot be sealed. Examples include chains on farm equipment, bicycles, and chain saws. These chains will necessarily have relatively high rates of wear, particularly when the operators are prepared to accept more friction, less efficiency, more noise and more frequent replacement as they neglect lubrication and adjustment.

Many oil-based lubricants attract dirt and other particles, eventually forming an CZPT paste that will compound wear on chains. This problem can be circumvented by use of a “dry” PTFE spray, which forms a solid film after application and repels both particles and moisture.

VARIANTS DESIGN

Layout of a roller chain: 1. Outer plate, 2. Inner plate, 3. Pin, 4. Bushing, 5. Roller
If the chain is not being used for a high wear application (for instance if it is just transmitting motion from a hand-operated lever to a control shaft on a machine, or a sliding door on an oven), then 1 of the simpler types of chain may still be used. Conversely, where extra strength but the smooth drive of a smaller pitch is required, the chain may be “siamesed”; instead of just 2 rows of plates on the outer sides of the chain, there may be 3 (“duplex”), 4 (“triplex”), or more rows of plates running parallel, with bushings and rollers between each adjacent pair, and the same number of rows of teeth running in parallel on the sprockets to match. Timing chains on automotive engines, for example, typically have multiple rows of plates called strands.

Roller chain is made in several sizes, the most common American National Standards Institute (ANSI) standards being 40, 50, 60, and 80. The first digit(s) indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers. Thus, a chain with half-inch pitch would be a #40 while a #160 sprocket would have teeth spaced 2 inches apart, etc. Metric pitches are expressed in sixteenths of an inch; thus a metric #8 chain (08B-1) would be equivalent to an ANSI #40. Most roller chain is made from plain carbon or alloy steel, but stainless steel is used in food processing machinery or other places where lubrication is a problem, and nylon or brass are occasionally seen for the same reason.

Roller chain is ordinarily hooked up using a master link (also known as a connecting link), which typically has 1 pin held by a horseshoe clip rather than friction fit, allowing it to be inserted or removed with simple tools. Chain with a removable link or pin is also known as cottered chain, which allows the length of the chain to be adjusted. Half links (also known as offsets) are available and are used to increase the length of the chain by a single roller. Riveted roller chain has the master link (also known as a connecting link) “riveted” or mashed on the ends. These pins are made to be durable and are not removable.

USE

An example of 2 ‘ghost’ sprockets tensioning a triplex roller chain system
Roller chains are used in low- to mid-speed drives at around 600 to 800 feet per minute; however, at higher speeds, around 2,000 to 3,000 feet per minute, V-belts are normally used due to wear and noise issues.
A bicycle chain is a form of roller chain. Bicycle chains may have a master link, or may require a chain tool for removal and installation. A similar but larger and thus stronger chain is used on most motorcycles although it is sometimes replaced by either a toothed belt or a shaft drive, which offer lower noise level and fewer maintenance requirements.
The great majority of automobile engines use roller chains to drive the camshaft(s). Very high performance engines often use gear drive, and starting in the early 1960s toothed belts were used by some manufacturers.
Chains are also used in forklifts using hydraulic rams as a pulley to raise and lower the carriage; however, these chains are not considered roller chains, but are classified as lift or leaf chains.
Chainsaw cutting chains superficially resemble roller chains but are more closely related to leaf chains. They are driven by projecting drive links which also serve to locate the chain CZPT the bar.

A perhaps unusual use of a pair of motorcycle chains is in the Harrier Jump Jet, where a chain drive from an air motor is used to rotate the movable engine nozzles, allowing them to be pointed downwards for hovering flight, or to the rear for normal CZPT flight, a system known as Thrust vectoring.

WEAR

 

The effect of wear on a roller chain is to increase the pitch (spacing of the links), causing the chain to grow longer. Note that this is due to wear at the pivoting pins and bushes, not from actual stretching of the metal (as does happen to some flexible steel components such as the hand-brake cable of a motor vehicle).

With modern chains it is unusual for a chain (other than that of a bicycle) to wear until it breaks, since a worn chain leads to the rapid onset of wear on the teeth of the sprockets, with ultimate failure being the loss of all the teeth on the sprocket. The sprockets (in particular the smaller of the two) suffer a grinding motion that puts a characteristic hook shape into the driven face of the teeth. (This effect is made worse by a chain improperly tensioned, but is unavoidable no matter what care is taken). The worn teeth (and chain) no longer provides smooth transmission of power and this may become evident from the noise, the vibration or (in car engines using a timing chain) the variation in ignition timing seen with a timing light. Both sprockets and chain should be replaced in these cases, since a new chain on worn sprockets will not last long. However, in less severe cases it may be possible to save the larger of the 2 sprockets, since it is always the smaller 1 that suffers the most wear. Only in very light-weight applications such as a bicycle, or in extreme cases of improper tension, will the chain normally jump off the sprockets.

The lengthening due to wear of a chain is calculated by the following formula:

M = the length of a number of links measured

S = the number of links measured

P = Pitch

In industry, it is usual to monitor the movement of the chain tensioner (whether manual or automatic) or the exact length of a drive chain (one rule of thumb is to replace a roller chain which has elongated 3% on an adjustable drive or 1.5% on a fixed-center drive). A simpler method, particularly suitable for the cycle or motorcycle user, is to attempt to pull the chain away from the larger of the 2 sprockets, whilst ensuring the chain is taut. Any significant movement (e.g. making it possible to see through a gap) probably indicates a chain worn up to and beyond the limit. Sprocket damage will result if the problem is ignored. Sprocket wear cancels this effect, and may mask chain wear.

CHAIN STRENGTH

The most common measure of roller chain’s strength is tensile strength. Tensile strength represents how much load a chain can withstand under a one-time load before breaking. Just as important as tensile strength is a chain’s fatigue strength. The critical factors in a chain’s fatigue strength is the quality of steel used to manufacture the chain, the heat treatment of the chain components, the quality of the pitch hole fabrication of the linkplates, and the type of shot plus the intensity of shot peen coverage on the linkplates. Other factors can include the thickness of the linkplates and the design (contour) of the linkplates. The rule of thumb for roller chain operating on a continuous drive is for the chain load to not exceed a mere 1/6 or 1/9 of the chain’s tensile strength, depending on the type of master links used (press-fit vs. slip-fit)[citation needed]. Roller chains operating on a continuous drive beyond these thresholds can and typically do fail prematurely via linkplate fatigue failure.

The standard minimum ultimate strength of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)2. X-ring and O-Ring chains greatly decrease wear by means of internal lubricants, increasing chain life. The internal lubrication is inserted by means of a vacuum when riveting the chain together.

buy drive chain

Buying a drive chain requires a certain understading of its characteristics. This article discusses the different types of chains available, including Silent, Flat-top, and Duplex. By the end of this article, you should have a basic understanding of what each type of chain is for. First, here are some basic rules to keep in mind when shopping for a chain. To find the drive chain that best suits your needs, read on.

roller chain

Choosing the right roller chain for your drive chain depends on several factors. First, you have to determine the motor horsepower and rpm for the small drive sprocket. These values ​​determine the size of the chain and the number of teeth on the drive sprocket. Next, you need to determine the size of the conveyor chain, it can be the horizontal, vertical, or curved radius. Depending on your specific needs, you can also choose between two-strand or three-strand chains.
The roller chain of the drive chain must be properly tensioned. It should also have a proper lubrication system. Chain sag should not exceed two to four percent of the center distance (the distance between the two axles). Also, it shouldn’t make any unusual noises or obvious problems. One of the main reasons for excessive wear is the size of the load. Each chain has a specified maximum working load.
The maximum roller chain load must be less than 1/9 or 6 times the tensile strength of the drive chain. This amount should not exceed this threshold, as exceeding this level will result in chain plate fatigue. To avoid this, you should use a roller chain with a higher number of strands. Also, for high power requirements, a roller chain with a higher number of strands is recommended. One final tip for choosing a drive chain: it should not be used when there is a high risk of corrosion or rusting.
The materials used to manufacture roller chains vary according to the specific application. Common materials include steel and stainless steel. However, stainless steel is used in food processing machinery and other environments that require lubrication. Brass and nylon are also sometimes used. These factors determine the selection of suitable materials for the drive chain. If you are not sure which material to use, you can consult an industry professional. These professionals will help you choose the right chain for the job at hand.
chain

mute chain

The design of the silent transmission chain is as follows: the large chain plates 2 are stacked one on top of the other in the direction of the chain length. The connecting rods are connected by connecting pins 3. The outermost and central guide plates 4 are fastened to the connecting pins 3 by means of rivets. This construction helps minimize friction on the sliding surfaces of the chain. Chainplate 2 of the silent transmission chain is usually made of stainless steel.
The link plates are made of steel and have a rectangular shape with pinholes 41. These guide plates have no teeth but have curved surfaces that guide the silent drive chain on the sprockets. In addition, the rear portion of the guide plate is higher than the portion of the chainplate. This feature improves pitch balance. The present invention is also applicable to silent transmission chains using rockers.
When it comes to chain design, it’s important to remember that silent drive chains are often used in automotive engines, especially timing and cam drives. This type of drive reduces noise and vibration due to its low engagement angle and links engagement with the sprocket. However, these applications are not limited to timing and cam drives; they can also be used for front-wheel power transmission. For example, silent drive chains are designed to resemble those used in NASCAR racing engines.
The design of the silent drive chain is based on the structure of the roller chain. Its components are standardized and manufactured according to pitch. There are single-row and multi-row versions. Quiet chains, also known as inverted tooth chains, are shaped to reduce noise from stretching. It’s also designed to minimize the amount of friction caused by small changes in pitch. Its teeth don’t slide against each other, so the chain is smoother and more durable.

flat top chain

One of the important parts of the flat top chainplate system is the hinge pin, which is used to fix the chainplate and is responsible for the smooth and efficient conveying of the chainplate. There are several types of hinge pins, including single hinge pins and double hinge pins. The single hinge pin is suitable for the chainplate with a small span and small bearing capacity, and the double hinge pin is suitable for the chainplate with a large span and high bearing capacity.
The side bending flat top chain is suitable for conveying large and medium workpiece pallets. They can be made of steel or plastic, each with its own advantages. Both chainplates are designed to convey material smoothly. Side curved flat-top chains can be used on straight conveyors. They have a low coefficient of friction and can transport weights up to 1.2 kg/cm. They can also be combined with HD profiles.
Flat top drive chains are usually made of plastic material and come in two types: tabletop chains and buffer chains. They come in a variety of widths, but the most popular are standard widths, ranging from 3.25 inches to 12 inches. MatTop chains are usually shipped in 10-foot lengths. They come in different styles, but they all have the same basic specs. Tabletop chains are designed for general conveying, while pad chains are used for specific applications. Solid top chains are suitable for conveying bulk materials, while wide pad chains can handle large volumes of fluids and/or solid-solid mixtures.
These chain conveyors can be used to convey, connect or lift small items. This type of chain is especially useful in industries where the product is hot or greasy. The modular design of these chains allows them to be configured in three dimensions, making them suitable for production changes and transitions. They also help reduce slack in the chain. Flat top chains are commonly used in final assembly and mechanical or paint restoration in the automotive industry.

double chain

Besides the roller chain, another type of chain drive is the double drive chain. This type of chain consists of a series of short cylindrical rollers connected together by side links and driven by gears called sprockets. This type of chain is very reliable and only requires a tractor with a high rpm PTO. It is manufactured by CZPT and is available in many different sizes and finishes.
chain

Self-lubricating chain

Self-lubricating drive chains are the ideal solution for applications that do not require the relubrication of conventional chains. This maintenance-free roller chain features fully heat-treated components that increase the chain’s fatigue resistance and strength. It’s sintered alloy bushings are oil-impregnated, reducing the chance of premature wear and elongation. Its self-lubricating properties enhance its durability and work well even in hard-to-reach places.
CZPT self-lubricating roller chains feature preloaded sintered steel bearing pins and oil-impregnated sintered bushings. These chains are drop-in replacements for standard roller chains and run on the same sprockets as standard chains. In addition to being maintenance-free, self-lubricating roller chains are compatible with most existing sprockets and are ideal for demanding applications.
The O-ring chain concept was used to develop self-lubricating systems. It has two or more annular grease storage chambers. A self-lubricating bushing roller chain has an oil reservoir between its pin chain and the roller chainplate. A grease seal between these two plates isolates the moving parts and keeps the joints well lubricated. O-rings are made of special nitrile rubber, whose properties vary by application.
CZPT SLR conveyor chains and CZPT SLR drive chains have rollers on sintered bushings. CZPT SLR chains and SLR conveyor chains are self-lubricating and have a higher working load than standard ANSI chains. They may not be interchangeable with other self-lubricating chains from other manufacturers. Self-lubricating drive chains are the best solution for demanding industrial applications requiring heavy-duty, reliable conveying.

Choosing a drive chain for a belt conveyor

The drive chain is used to move heavy objects on the conveyor chain. Chains are magnetic, antistatic, high temperature, or chemical resistant, depending on the application. These types of drive chains are used in many different industries. A common machine that uses this type of drive is a chain hoist. Chain hoists are designed to lift heavy loads with minimal effort. Chains are often used to transport heavy loads.

roller chain

Whether using a roller chain as a drive chain or a belt conveyor can be tricky. Whether it’s a small low-speed drive with manual lubrication or a high-speed pump-lubricated drive with multiple sprockets, there are several factors to consider when choosing a roller chain. First, you need to consider motor horsepower and rpm. The speed of the motor determines how much chain you need. For example, if you are using a low-speed drive, you will need to choose a low-pitch, high-pitch chain. Another thing to consider is chain length – ideally, you can go for an even number of sprockets and chains, but never go smaller.
The lubrication system is also important because the lubrication system must be able to deliver enough oil. The type of oil used to lubricate a chain depends on its operating environment, temperature and speed. Wear is caused by pressure on the bearing, angular sliding of the pins, and rotation of the rollers. There are five different types of lubrication methods available, depending on the system used. A high-quality carbon steel chain is a major advantage when operating at high temperatures, as it can withstand higher temperatures.
The materials of construction for roller chains vary by application. Typically, the most common materials are steel and stainless steel, but sometimes alloy steels are used in food processing machinery that may have lubrication problems. Nylon and brass are also sometimes used. Some industries require heavy-duty chains. If you need an extremely heavy chain, you may want to consider a heavy-duty roller chain. If you are not sure which type of chain is best for your application, consult an industry expert.
Unlike other chains, roller chains are more efficient from a size and weight perspective. While solution chains are useful in some situations, drive chains are more effective for dirty work and slipping on tracks. They are commonly used in construction and manufacturing. There are other advantages to using a drive chain. They are generally stronger than belts, which is a huge benefit. So, if you’re wondering which is better, here are them:

Multi-strand roller chain

The multi-strand roller chains for drive chains market is expected to grow at a CAGR of over 20% during the forecast period. Market reports cover product demand, supply, and cost. The report covers the global market including company profiles, product details, and contact information of key players. It also takes into account the revenue generated by different application areas. The report contains 159 pages of useful information and data. It is an essential tool for anyone involved in drive chain manufacturing.
The essential characteristics of multi-strand chains are their power ratings and allowable bearing area pressures. Power rating is an important characteristic that determines the chain’s ability to transmit a specific load. Typically, multi-strand chains are rated in the range of 12,000 watts per strand. However, their capabilities are limited by link plate fatigue, roller impact fatigue, and wear between pins and bushings.
Energy Series chains are ideal for high-speed and high shock load applications. The chain is designed to provide reliable power and withstand the rigors of the oil and gas industry. It uses high-strength steel and double-coated rolls. These chains come in different lengths and come in two types: single-strand and multi-strand. It is best to consult a professional to find out which chain best suits your needs.
The global multi-strand roller chains market is expected to grow at a CAGR of over 7% during the forecast period. From 2011 to 2019, the industry is expected to grow by nearly 6%. However, the outlook for this market is not optimistic, with some companies experiencing negative growth over the past year. Nonetheless, slowing global economic growth and tightening COVID-19 regulations are likely to hinder the market growth.
Although requirements vary by application, it must be remembered that the load on a multi-strand roller chain must not be greater than 1/9 or 1/6 of the tensile strength of the chain. If the load exceeds this threshold, the chainplates will fatigue. This is the main reason why roller chains are expensive. However, this is not always the case. Multi-strand roller chains are a great idea if you are looking for an affordable and reliable drive chain.

double chain

If you’re looking for an industrial-grade drive chain, you’ve probably considered a double chain. The chain meshes with the sprockets on either side of the gears. It comes in different styles, each with its own advantages and disadvantages. The CZPT duplex series has twice the power capacity of standard SC duplex chains. This type of chain is usually best for new applications. On the other hand, SC double chain chains are the cheapest but have less weight and power capacity.
Another option is a triple drive chain. This type of drive chain has an additional row of plates and contains three sprockets. Its unique design reduces the weight and impact velocity of the timing chain. It is usually used in automotive applications. It is ideal for low to medium-load timing applications. It is also available in acoustically optimized versions. Three-quarter inch pitch double chain chains are widely used in gasoline engine aids and timing drives.
chain

flat top chain

High friction rubber is usually installed on the top or bottom of a flat top drive chain to improve its high friction surface and prevent interference during side bend conveying. The chain plate can be customized with thin rubber layer or thick elastic polyurethane rubber according to customer requirements. In addition to providing high friction, the flat top chain also provides excellent anti-slip properties for glass bottles.
Premium steel flat top chain with high quality surface finish and excellent wear resistance. They have a high level of noise reduction and can be used in heavy duty conveying applications. These chains are available in a variety of alloys such as stainless steel or aluminum. Some models are designed to be very rugged and last longer. Aluminum and galvanized steel chains are popular choices for these chains.
Flat Top Drive Chain Conveyors are versatile and come in an endless combination of configurations. Drives can be connected end-to-end to form long conveyor lines, while side-curved flat-top chains are versatile enough to handle tandem, serpentine or carousel configurations. Standard and heavy duty models are also available. Flat top chains can be used in many different applications including food, beverages and other commodities.
Standard flat top chains are usually rectangular or L-shaped and designed for use on straight conveyors. In some cases, space constraints may require a U-shaped or rectangular conveyor line. For smoother conveying, side-curved flat-top chains can be used. These chains are paired with regular rectangular chain plates and tall pins for high load capacity. They come in different widths, including multi-strand chains.
