What Are The Common Causes Of Damage To The Motorcycle Chain

Motorcycle Chain, as a common transmission force device, uses a hyperbolic arc "chain" design to reduce friction. It is used in places where the power is relatively large and the running speed is relatively slow. It has obvious advantages over belt transmission. Let's take a look at the common causes of damage to the Motorcycle Chain:

1. Mechanical wear
After the chain is worn out, the chain links and the total length of the chain are extended, and when meshing, the meshing point moves along the working side of the tooth profile to the top of the tooth, causing the tooth to skip or disconnect the chain. When the outer surface of the pin shaft and the sleeve inner group is worn out, the hinge gap increases, which causes the outer link to extend. The pitch of the inner chain links depends on the bus bars on the same side of the adjacent rollers. Because the rollers have little wear on the outer surface and the sleeves, the inner chain links hardly extend.

2. Fatigue wear
Due to the tight and loose edges of the chain, the chain parts are subject to alternating loads of varying sizes. In each revolution of the chain link, the force of the chain is stretched and twisted, the force of the pin is sheared, kneaded, and twisted, the roller is kneaded and impacted, and the sleeve is kneaded and sheared. Cut and shock. Under the effect of alternating load, the parts produce cracks and the cracks propagate, causing fatigue and fracture.
