Failure of hollow pin chain is common, but if it is damaged as a transmission element, the whole transmission system will be affected. We should be clear about which faults will lead to the failure of the hollow pin chain during its use, and guard against them in the later period.

If the hollow pin chain has good durability and good lubricity but still fails, it is basically caused by fatigue damage. The tightness, load and acting force of the hollow pin chain may cause fatigue fracture. In view of this situation, the effective solution is to improve the strength of the hollow pin chain, which requires chemical heat treatment or shot peening.

In addition to the strength of the hollow pin chain itself, every time its connection strength is damaged, the hollow pin chain will also show failure when it breaks up. In addition, we cannot ignore the failure caused by wear, because the length of the hollow pin chain will increase after wear, so there will be a tooth jump or chain drop-in use. It can be seen that its wear resistance is also very critical.
