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.

How does a gear chain contribute to overall system efficiency?

A gear chain plays a crucial role in improving the efficiency of a mechanical system. Here are several ways in which a gear chain contributes to overall system efficiency:

1. Power Transmission:

– A gear chain efficiently transfers power from the input shaft to the output shaft. The interlocking teeth of the gears ensure a positive and reliable power transfer, minimizing energy losses due to slippage or inefficiencies.

2. Speed Reduction or Increase:

– Gear chains allow for speed reduction or increase by using gears of different sizes. This enables matching the speed of the output shaft to the specific requirements of the application, optimizing system performance.

3. Torque Amplification or Reduction:

– Gear chains can amplify or reduce torque through gear ratio selection. By choosing the appropriate gear combination, the gear chain can increase torque for applications that require higher force output or decrease torque for precision and high-speed applications.

4. Compact Design:

– Gear chains are compact and can transmit high power in a relatively small footprint. This allows for efficient space utilization in mechanical systems, especially where space is limited.

5. Precise and Reliable Operation:

– Gear chains provide precise and repeatable motion control due to the accurate positioning of the gear teeth. This accuracy improves the overall efficiency of the system by minimizing errors and ensuring consistent performance.

6. Low Energy Losses:

– The meshing of gear teeth in a gear chain results in minimal energy losses compared to other power transmission systems, such as belts or chains. This efficiency helps reduce energy consumption and improves the overall system efficiency.

7. Durability and Longevity:

– Gear chains are designed to withstand high loads, operate at various speeds, and provide long service life. Their durability reduces the need for frequent replacements or repairs, enhancing the overall efficiency and productivity of the system.

8. Reduced Maintenance:

– Gear chains require minimal maintenance when properly lubricated and maintained. This reduces downtime and maintenance costs, improving the overall system efficiency.

By incorporating a gear chain into a mechanical system, engineers can achieve efficient power transmission, precise control, and reliable operation. The inherent advantages of gear chains contribute to the overall efficiency, performance, and longevity of the system.

Can a gear chain be repaired if it is damaged?

In most cases, if a gear chain is damaged, it cannot be repaired and will need to be replaced entirely. The nature of damage to a gear chain, such as broken teeth, worn links, or damaged rollers, often requires the replacement of the affected components.

Attempting to repair a damaged gear chain can compromise its integrity and performance, leading to safety hazards and further damage. It is recommended to consult the manufacturer or a qualified professional to assess the extent of the damage and determine the appropriate course of action.

If a gear chain is found to be damaged, it is important to identify the root cause of the damage. This could be due to factors such as overloading, misalignment, inadequate lubrication, or excessive wear. Addressing the underlying issue is crucial to prevent future damage and ensure the reliability of the gear chain system.

How do you select the right gear chain for your application?

When selecting the right gear chain for your application, there are several factors to consider. Here are some key considerations:

– Load and Power Requirements: Determine the maximum load and power requirements of your application. This will help you determine the size and strength of the gears and chain needed to handle the load and transmit the required power.

– Speed and Torque: Consider the operating speed and torque requirements of your application. Higher speeds and torque levels may require specific gear ratios and materials to ensure smooth and efficient operation.

– Environmental Conditions: Evaluate the environmental conditions in which the gear chain will operate. Factors such as temperature, moisture, dust, and chemicals can affect the performance and durability of the chain. Choose a gear chain that is suitable for the specific environment.

– Noise and Vibration: Consider the noise and vibration levels that are acceptable for your application. Some gear chains are designed to minimize noise and vibration, which may be important in certain applications.

– Efficiency and Precision: Depending on the application, you may require high efficiency and precise motion transmission. Consider gear chains that offer low backlash, high gear engagement efficiency, and accurate positioning capabilities.

– Maintenance and Lubrication: Assess the maintenance requirements and lubrication preferences of the gear chain. Some gear chains may require periodic lubrication or maintenance, while others may offer self-lubricating or maintenance-free options.

– Cost: Evaluate the cost of the gear chain, including initial purchase, installation, and maintenance expenses. Consider the long-term reliability and cost-effectiveness of the gear chain for your specific application.

By considering these factors and consulting with gear chain manufacturers or experts, you can select the right gear chain that meets the requirements of your application in terms of load capacity, speed, durability, precision, and cost-effectiveness.
