Analyzing chain fatigue failures

Chainshowing fatigue

Assuming that the lubrication conditions are better, and it is also a relatively wear-resistant chain, the failure time is basically caused by fatigue damage.Since the chain has tight and loose sides, the loads that these components are subjected to also vary.When the chain rotates, it will be stretched or bent due to the force. The various parts in the chain will gradually have cracks due to various external forces. After a long time, the cracks will appear. It will gradually grow larger, and fatigue and breakage may occur.Therefore, when producing the chain, various measures will be taken to improve the strength of the parts, such as the application of chemical heat treatment to make the parts appear carburized, and there are also methods such as shot peening.
