What is the main reason for chain wear and breakage in a chain coupling?

The main reason for chain wear and breakage in a chain coupling is often linked to coupling misalignment or insufficient lubrication. When the components of the coupling are not properly aligned, it results in uneven load distribution across the chain. This misalignment can cause certain links in the chain to experience excessive wear due to increased friction and stress, leading to a greater risk of failure.

Moreover, lubrication is critical in reducing friction between the moving parts of a chain coupling. Insufficient lubrication means that the links do not glide smoothly past each other, which can accelerate wear and ultimately lead to breakage. Proper lubrication ensures that the chain operates efficiently and extends its lifespan.

When assessing the condition and performance of a chain coupling, it's vital to regularly check for proper alignment and lubrication to prevent premature wear and ensure reliable operation.
