What is a probable cause for chain wear and breakage in a chain type coupling?

Chain wear and breakage in a chain type coupling is often attributed to coupling misalignment. When the coupling is misaligned, it places undue stress on the chain and sprockets. This misalignment can lead to uneven distribution of load, causing certain sections of the chain to wear down more quickly than others. Over time, the wear can result in increased friction and can ultimately lead to breakage.

Proper alignment in a chain type coupling ensures that the load is evenly distributed across the chain's links. This helps maintain the chain's integrity and prolongs its lifespan, preventing premature failure. Regular maintenance checks and adjustments for alignment are critical to ensure optimal performance and prevent extensive wear or damage.
