How to deal with sprocket after it is worn

If there is no friction, the two objects cannot move with each other, the car cannot move forward and backward without friction, and the shoes cannot move forward without friction with the ground. Friction seems simple, but it is a very important term. This seems to be indispensable, but we can't deny that there will be wear and tear when there is friction, and there is such a relationship between the sprocket and the chain. The two interact with each other and each other is killing each other. The degree of wear is different. We must deal with it according to the situation. After the sprocket is worn, first check whether it is serious. If it is worn in a small area and can continue to be used, it is clearly marked. It is often paid attention to the wear condition during use, so that it can be replaced in time to minimize our losses. If it is serious, the new sprocket should be replaced in time, and the chain should be replaced at the same time to ensure good meshing. If you simply replace the sprocket and cause poor meshing, it will accelerate the wear of the sprocket. In terms of grinding, although the cost was reduced at that time, in the long run, your loss will be much greater.
