1. The tightness of the sprocket should be appropriate, too tight will increase the power consumption, and the bearing is easy to wear; too loose the sprocket is easy to jump and off chain. The tightness of the spruck is about 2% - 3% of the center distance of the two sprucks when it is lifted or pressed from the middle of the spruck.

2. The sprinket shall be installed on the shaft without swing and skew. The end faces of two sprockets in the same drive assembly should be in the same plane. When the center distance of the sprockets is less than 0.5m, the deviation can be 1mm; when the center distance of the sprockets is more than 0.5m, the deviation can be 2mm. However, it is not allowed to have friction on the side of the sprocket teeth. If the offset of two wheels is too large, it is easy to cause chain disconnection and accelerated wear. The offset must be checked and adjusted when replacing the socket.

3. After the serious wear of the sprocket, the new sprocket and the new sprocket should be replaced at the same time to ensure good engagement. You can't just replace new sprockets or new sprockets. Otherwise, it will result in poor engagement and accelerate the wear of new sprockets or new sprockets. When the sprocket tooth surface is worn to a certain extent, it should be turned over in time to extend the service time.

4. The new sprocket is too long or elongated after use, which is difficult to adjust. The chain link can be removed according to the situation, but it must be an even number. The chain link shall pass through the back of the socket, the locking piece shall be inserted outside, and the opening of the locking piece shall be in the opposite direction of rotation.
