The main forms of chain drive are as follows:
(1) Fatigue damage of chain plate: Under the repeated action of loose edge tension and tight edge tension, the chain plate will undergo fatigue failure after a certain number of cycles. Under normal lubrication conditions, the fatigue strength of the chain plate is the main factor that limits the load-bearing capacity of the chain drive.
(2) Impact fatigue damage of rollers and sleeves: The meshing impact of the chain drive is first borne by the rollers and sleeves. Under repeated impacts and after a certain number of cycles, the rollers and sleeves may suffer impact fatigue damage. This failure mode mostly occurs in medium and high-speed closed chain drives.
(3) Gluing of the pin and the sleeve: When the lubrication is improper or the speed is too high, the working surfaces of the pin and the sleeve will glue. Gluing limits the limit speed of the chain drive.
