The main failure mode of the roller chain drive

The main failure mode of the chain drive are the following:

(1) roller chain plate fatigue failure

Chain loose side under repeated tension and tight side tension, after a certain number of cycles, the chain plate fatigue failure may occur. Under normal lubrication conditions, the fatigue strength is the main factor defining the carrying capacity of the chain drive.

(2) roller sleeve of impact fatigue damage

Chain drive meshing impact borne by the first roller and the sleeve. Under repeated shocks, after a certain number of cycles, roller, sleeve will impact the fatigue failure occurs. This failure occurred in the form of high-speed closed chain drive.

(3) roller chain pin and sleeve glued

When the wheel speed of up to a certain value, the impact energy links bitten by the increase between the pin and sleeve lubricants are destroyed, so that both the direct contact with the work surface at high temperature and pressure, thereby lead to gluing. Therefore, it glued to a certain extent, limit the chain of transmission of the speed limit.

(4) chain hinge wear

Hinge worn links becomes long, prone to jump off the teeth or chains. Open drive, harsh environmental conditions or poor lubrication of the seal when the hinge can easily cause wear and tear, thereby drastically reducing the life of the chain.

(5) Overload pull off

This often occurs in low-speed pull off overloaded or severe overload of the drive.
