How do you properly tension a conveyor chain?

Properly tensioning a conveyor chain is crucial for its smooth operation and to prevent issues like chain slipping or excessive wear. Here are the steps to properly tension a conveyor chain:

  1. Identify the Tensioning Points: Determine the locations where the conveyor chain can be tensioned. These are typically at the ends of the chain or at specific tensioning devices.
  2. Loosen the Tensioning Devices: If there are tensioning devices in place, such as adjustable bolts or tensioning screws, loosen them to allow for adjustment.
  3. Apply Tension: Apply tension to the conveyor chain by either manually pulling the chain or using a tensioning tool. The amount of tension required depends on the chain type and the manufacturer’s recommendations.
  4. Check the Tension: Use a tension gauge or other suitable method to measure the tension of the conveyor chain. The tension should fall within the specified range provided by the chain manufacturer.
  5. Adjust the Tension: If the tension is too loose or too tight, make adjustments accordingly. Tighten or loosen the tensioning devices until the desired tension is achieved.
  6. Secure the Tensioning Devices: Once the proper tension is achieved, securely tighten the tensioning devices to hold the chain in place.
  7. Verify the Tension: After tensioning the chain, perform a visual inspection and run the conveyor to ensure the chain runs smoothly without excessive slack or tightness. Make any further adjustments if necessary.

It’s important to refer to the specific guidelines provided by the conveyor chain manufacturer for proper tensioning instructions, as the exact method may vary depending on the chain type and design. Regularly check the tension of the conveyor chain and make adjustments as needed to maintain optimal performance.

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 upon 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. 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 forward 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.

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).

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.

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 5 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 2 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 3 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.

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.

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 upon 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. 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 forward 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.

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.

Different types of drive chains

There are many different types of drive chains. You should be able to differentiate between roller chains, forged rivetless chains, double chains, flat-top chains, and helical chains by the terms used. This article will provide information on the different types of chains. Then, you can choose the right 1 according to your needs. If you haven’t purchased a chain yet, read this article to get started. It will also provide information on the pros and cons of each type.

roller chain

There are several differences between drive chains and roller chains, but in essence, the 2 are functionally similar. The choice of which type to use depends largely on the type of environment it will be exposed to. While roller chains are suitable for clean indoor environments, they are not very forgiving when it comes to rubbing against the rails. Following are the main differences between a drive chain and a roller chain. Using the correct drive chain is essential for a smooth and efficient running machine.
Roller chain drive chains come in many different weights and tensile strengths. For light-duty applications, use a smaller pitch chain. For heavy-duty applications, use larger pitch chains. The design simplicity of these chains makes them ideal for a variety of applications. While they are great for a variety of applications, the durability of these chains makes them ideal for a variety of applications. Some of the main uses of roller chain drive chains are listed below.
When replacing the drive chain, be sure to follow the safety guidelines. The most important thing to remember is not to place the chain on a dirty floor as it may cause stretch or damage. After removing the chain from the sprocket, apply the measured load specified by ANSI to it. If the load exceeds this value, the chain may bend. A suitable load for measuring a drive chain should be at least 6 links.
While roller chains are usually made of carbon steel, some are made of stainless steel and are used in food processing machinery. In these environments, the chain may be made of stainless steel for lubrication. Brass and nylon are also sometimes used to meet these requirements. Regardless of the application, however, choosing the right drive chain is critical to the success of a roller chain machine. It is important to maintain the proper balance between the roller chain and the machine.
To properly use a roller chain, first determine the size of the sprocket used for the drive. The size of the chain should be smaller than the smallest sprocket to prevent tooth interference and provide adequate winding on the smaller sprocket. A good practice is to choose a drive chain with a center distance of 30 to 50 times the chain pitch. The longest possible center-to-center distance is approximately 80 times the chain pitch but is not recommended for high-speed applications.

Drop forged rivetless chain

Drop-forged rivetless drive chains are made of drop-forged steel components. Their proportions are suitable for strength and lightweight. Forged rivetless chains are generally divided into 3 types. Each of these types has its own set of important specifications. Key topics include minimum ultimate tensile strength, chain length tolerances, and link dimensions. Read on to learn more about each type and its uses.
One of the main features of forged rivetless chains is that, despite their relatively low price, they are designed to be very durable. The quality of a forged chain depends on the structure and design of the chain. The manufacturer of this type of drive chain is CZPT, which has a large stock of these chains. The chain is proof tested after assembly and comes with a two-year parts replacement warranty.
Forged rivetless chains are available in a variety of pitch sizes and strength grades. They are made of cast manganese or alloy steel and have an average strength of 24,000 to 300,000 pounds. These chains are suitable for automotive, conveyor, and material handling as well as meat packaging, sugar processing, and steel mill applications. They are also widely used in conveying systems. To ensure quality and performance, manufacturers offer a variety of forged chains.
CZPT offers forged CZPT drive chains for fatigue-free operation. The chain includes a solid one-piece forged drive pawl for optimum durability. Chains are available in Figure 8 and in D-shape styles. For more information, please contact CZPT directly. Custom Drop-Forged rivetless drive chains can be ordered. Manufacturers also offer custom chains for specific application needs.

double chain

Duplex drive chains have 2 sets of rollers instead of one, producing twice the power. Double chain roller chains have pins and roller bearings, while triple chain chains have an extra row of plates to accommodate the 3 sprockets. They are usually interchangeable with each other. They are available for US, UK, and ISO standards. They are made of carbon steel, stainless steel, and nickel or nickel-plated.
chain

flat top chain

Flat-top drive chains are ideal for curved or straight tracks and come in many different types and thicknesses. These chains are highly resistant to wear and are usually made of steel, stainless steel, or plastic. CZPT manufactures special brands of flat-top chains with high wear resistance and excellent noise reduction. In addition to being versatile, flat-top chains can be used in a variety of industrial applications.
There are 2 main types of CZPT chains: solid top or raised rib. One piece is formed from a single unit link and the other has roller base links for added strength. The two-piece chain combines flat tabletop links and a roller bottom chain for added strength. These chains are available in widths up to 20 feet and are available in a variety of widths. These chains are available in stainless steel, cast iron, or plastic.
The hinge pin is another important part of the flat top chain system. Support chain plate to ensure smooth conveying. The hinges are available in single hinge pin and double hinge pin styles. Standard hinge pins are designed for straight, narrow-width chainplates; double hinge pins are designed for longer, heavier products. The hinge pins also come in many different materials, including aluminum and galvanized steel. This allows for customization based on machine design, operating conditions, and drive method.
Whether your flat-top chain conveyor system is large or small, a high-quality flat-top chain will get the job done. With their low maintenance and low maintenance design, these chains are easy to clean and maintain. They can accommodate workpiece pallets of various sizes, and their flexibility makes them ideal for many different applications. They can also be highly customized for various industries. So if you need an industry-specific conveyor, then a flat-top drive chain is the way to go.
