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.

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.

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 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

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.

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). See the references for additonal information.

Can a gear chain be retrofitted into an existing system?

Yes, a gear chain can be retrofitted into an existing system under certain circumstances. Here are some considerations:

1. Compatibility:

– The existing system should have the necessary space and structural support to accommodate the gear chain. It’s important to assess whether the gear chain can be integrated without causing interference or compromising the overall functionality of the system.

2. Shaft Alignment:

– The alignment of the input and output shafts must be suitable for the installation of a gear chain. If the existing system has misalignment issues, they should be addressed before retrofitting the gear chain to ensure proper operation and minimize the risk of premature wear or failure.

3. Power and Torque Requirements:

– The gear chain selected for retrofitting should be capable of handling the required power and torque of the system. It’s essential to evaluate the load characteristics, speed, and operating conditions to choose the appropriate gear chain that meets the performance requirements.

4. Modifications and Adaptations:

– Depending on the specific system configuration, some modifications or adaptations may be necessary to accommodate the gear chain. This can include changes to the mounting arrangement, shafts, or other components. Professional engineering expertise may be required to ensure proper installation and functionality.

5. System Integration:

– The integration of the gear chain into the existing system should be carefully planned and executed. This involves ensuring proper alignment, adequate lubrication, and appropriate tensioning of the gear chain. It’s also important to consider the compatibility of other system components, such as bearings and seals, with the gear chain.

Before retrofitting a gear chain, it’s recommended to consult with experienced engineers or professionals familiar with the specific application and system requirements. They can provide guidance on the feasibility of retrofitting and help identify any potential challenges or modifications needed for a successful integration.

How do you troubleshoot common issues with gear chains?

Troubleshooting common issues with gear chains involves a systematic approach to identify and resolve the underlying problems. Here are some steps to troubleshoot gear chain issues:

1. Visual Inspection: Start by visually inspecting the gear chain for any visible damage, such as broken teeth, worn links, or misalignment. Look for signs of excessive wear, inadequate lubrication, or contamination.

2. Noise and Vibration: Listen for unusual noise or vibrations during operation. Excessive noise or vibration can indicate misalignment, worn gears, or inadequate lubrication.

3. Load and Torque: Check if the gear chain is handling the load and torque requirements of the application. Overloading can cause premature wear and damage to the chain.

4. Lubrication: Evaluate the lubrication system to ensure proper lubrication is provided to the gear chain. Inadequate or improper lubrication can lead to increased friction, wear, and overheating.

5. Alignment: Check the alignment of the gear chain and ensure that the gears are properly meshing. Misalignment can cause excessive wear and noise.

6. Maintenance Records: Review the maintenance records to ensure that the gear chain has been regularly inspected, lubricated, and maintained according to the manufacturer’s recommendations.

7. Consult the Manufacturer: If troubleshooting steps do not resolve the issue, it is advisable to consult the gear chain manufacturer or a qualified professional for further guidance and assistance.

By systematically addressing these troubleshooting steps, you can identify and resolve common issues with gear chains, ensuring their optimal performance and longevity.
