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 CZPT 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

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

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.

trencher chain

How do trencher chains perform in different soil types, such as rocky terrain or sandy soils?

Trencher chains’ performance can vary based on the soil type they encounter during trenching operations. Here’s how trencher chains typically perform in different soil types:

1. Rocky Terrain:

– In rocky terrain, trencher chains with carbide or hardened steel cutting teeth are preferred. These materials offer excellent wear resistance and toughness, enabling the chain to cut through rocks and other hard obstacles effectively.

– However, rocky soil conditions can still pose challenges, and trencher chains may experience increased wear due to the abrasive nature of rocks. Regular inspection and maintenance are crucial to ensure the chain remains in top condition.

2. Clayey Soil:

– Trencher chains usually perform well in clayey soil due to its relatively soft and cohesive nature. Standard trencher chains with regular cutting teeth can efficiently cut through clay, creating clean and precise trenches.

3. Sandy Soils:

– Sandy soils are generally easier to trench through, and standard trencher chains perform well in such conditions. The sand’s loose nature allows the chain to move smoothly and quickly, resulting in efficient trenching.

4. Loamy Soil:

– Loamy soil, which is a mixture of sand, silt, and clay, can offer moderate trenching challenges. Trencher chains with standard cutting teeth are typically suitable for loamy soil conditions.

5. Wet or Soft Soils:

– Wet or soft soils can be more challenging to trench through, as they may cause increased chain wear and the risk of chain clogging. Special attention to chain tension and soil conditions is essential to ensure smooth trenching.

– In such conditions, trencher chains with modified tooth configurations, such as cup-type teeth, can be beneficial, as they may provide better cutting and reduce clogging.

6. Compacted Soils:

– Compacted soils may require trencher chains with strong cutting teeth to penetrate the ground effectively. Carbide or hardened steel teeth can help maintain cutting performance in these conditions.

– Consider using trencher machines with higher horsepower for trenching in compacted soils to improve productivity.

Overall, trencher chains can be optimized for different soil types based on the cutting tooth material, tooth configuration, and machine power. Regular maintenance, proper chain tension, and selecting the right trencher chain for the specific soil conditions are vital to ensuring optimal trenching performance and extending the chain’s lifespan.

What are the common issues and troubleshooting tips for trencher chains, such as chain slipping or jamming?

Trencher chains may encounter various issues during operation, and understanding common problems and troubleshooting tips can help resolve them efficiently. Here are some common issues and their troubleshooting tips:

1. Chain Slipping:

Possible Causes: Chain slipping can occur due to insufficient tension, worn-out sprockets, or damaged chain links.

Troubleshooting Tips: Check and adjust the chain tension as per the manufacturer’s recommendations. Inspect the sprockets for wear or damage, and replace them if necessary. Examine the chain links for any signs of wear, bending, or stretching, and replace damaged links promptly.

2. Chain Jamming:

Possible Causes: Chain jamming can be caused by debris, rocks, or foreign objects getting stuck in the chain or guides.

Troubleshooting Tips: Stop the trencher machine immediately if you encounter a chain jam. Safely remove any debris or objects stuck in the chain and guides. Inspect the chain and guides for damage caused by the jam and make necessary repairs before resuming trenching.

3. Uneven Trench Depth:

Possible Causes: Uneven trench depth can result from improper chain tension, worn-out cutting teeth, or uneven ground conditions.

Troubleshooting Tips: Ensure the chain tension is properly adjusted for even trenching. Regularly inspect and replace worn-out cutting teeth to maintain consistent trench depth. If the ground conditions are uneven, adjust the trenching speed or use a different trencher attachment to achieve a smoother trench.

4. Excessive Chain Wear:

Possible Causes: Excessive chain wear can be caused by operating the trencher in abrasive soil conditions or using a worn-out chain.

Troubleshooting Tips: Choose the appropriate trencher chain with cutting teeth suitable for the soil conditions you are working in. Regularly inspect and maintain the trencher chain, including lubrication, to reduce wear and tear.

5. Chain Breakage:

Possible Causes: Chain breakage can occur due to overloading the trencher, using a damaged chain, or operating the machine at excessive speeds.

Troubleshooting Tips: Avoid overloading the trencher with large rocks or hard obstacles. Always use a well-maintained and undamaged chain. Operate the trencher at appropriate speeds recommended by the manufacturer.

Regular maintenance, proper tensioning, and choosing the right trencher chain for the soil conditions are essential to prevent issues and ensure smooth trenching operations. If problems persist, consult the trencher’s operation manual or seek assistance from a qualified technician or dealer.
