Everyone knows that a chain can act as a transmission, but the chain often fails. Today, let us know more about the chain!

Chain

1.The chain fails due to fatigue

Because the chain has tight edges and loose edges, the load on this part will also change. When the chain rotates, due to the tension or bending of the force, each component in the chain is subjected to various external forces, and cracks will slowly appear. Over time, the previous cracks will gradually grow , It may happen that the chain is tired and broken. Therefore, when running the chain, various measures must be taken to enhance the strength of the parts, such as applying chemical heat treatment to make the parts carburized, and shot peening.

2.The connection strength of the chain is damaged

Due to the load, when the outer link plate and pin and the inner link plate and the sleeve are in use, the joint may loosen, which will cause the eyelet of the link plate to wear. In severe cases, it will cause The length of the chain increases, showing a phenomenon of failure.

3.The chain fails during use due to wear and tear

In the process of using a chain, the chain often fails due to wear and tear. You should know that the length of the chain will increase after it is worn out, so it is likely that there will be tooth skipping or delinking during operation. In addition, the wear of the chain is usually in the center of the outer joint, but if the pin and the sleeve are worn, the gap between the hinges will increase, and the length of the outer joint will increase. After the length of the chain is increased to a certain range, there may be cases of de-linking. Therefore, the most important thing of the chain is its abrasion resistance.

Xiaobian Knowledge Area: During the use of the chain, static breaking, starting, braking and other actions will affect its performance, and may cause the chain to fail. In order to reduce the failure of the chain, the user should ensure the quality of the chain when purchasing and reduce the probability of its failure.
