Should the damaged sprocket and chain be replaced at the same time?

Some parameters of the chain drive, such as the number of teeth of the driving wheel and the driven sprocket, the number of parameters of the chain, as well as the power of the whole vehicle and the Gear ratio of each gear tooth, need to be carefully calculated before processing and Designed, it is also necessary to check before the sprocket factory, matching the best and the parameters.

Due to the long-term operation of the chain drive, the hinge and the teeth will undergo a certain amount of changes, such as the wear of the gear teeth and the length of the chain plate. Such a situation cannot be adjusted and must be replaced because the chain plate is long after the chain plate is long. The overall length will become longer than the distance between the teeth of the sprocket. We often think of picking up a chain link, which will not mesh well with the sprocket after loading, but there will be a "bite" chain during the rotation. In the case, not only the sound is increased, the wear is more intensified, but also the operation safety is unfavorable. In addition, if only one of the parts with a little wear is replaced, the pitch between the chain and the old sprocket does not match well. The best way to wear both is to replace the sprocket with the chain.
