A common form of failure of conveyor chains

2017-06-26
The failure forms of the conveying chain are mainly as follows:
(1) the fatigue failure chain of the chain chain plate under the repeated action of the loose edge tension and the tight side pulling force, the fatigue failure of the chain plate will occur after a certain number of cycles. Under normal lubrication condition, the fatigue strength of chain plate is the main factor to limit the carrying capacity of chain transmission.
(2) the impact fatigue of the conveying chain roller and sleeve, the meshing impact of the chain drive is first borne by the roller and sleeve. Under repeated repeated impact, after a certain number of cycles, the roller and sleeve may have impact fatigue damage. This kind of failure occurs mostly in medium and high speed closed chain transmission.
(3) when the feeding chain, pin and sleeve are glued improperly or improperly, or the speed is too high, the working surface of the pin and sleeve will be cemented. Gluing limits the limit speed of chain drives.
(4) the wear of the chain hinge is worn, the hinge is worn out, the chain link becomes longer, and it is easy to cause the tooth to jump or to remove the chain. Open transmission, poor environmental conditions or poor lubrication seal, it is easy to cause hinge wear, thereby dramatically reducing the service life of the chain.
(5) the conveying chain is overloaded and broken; this break is often caused by the transmission of low speed and heavy load.
