1. The tightness of the sprocket should be appropriate. If it is too tight, it will increase power consumption and the bearing is easy to wear; It is too loose, and the sprocket is easy to jump and fall off the chain. The tightness of the sprocket: lift or press down from the middle of the sprocket, and the center distance between the two sprockets is about 2% - 3%.
2. The sprocket shall be installed on the shaft without swing and skew. In the same transmission assembly, the end faces of two sprockets shall be located in the same plane. When the center distance of sprockets is less than 0.5m, the deviation can be 1mm; When the center distance of sprocket is more than 0.5m, the deviation can be 2mm. However, there shall be no friction on the side of sprocket teeth. If the deviation of two wheels is too large, it is easy to cause chain disengagement and accelerated wear. When replacing the sprocket, pay attention to check and adjust the offset.
3. After the sprocket is seriously worn, replace the new sprocket and the new sprocket at the same time to ensure good engagement. You cannot replace a new sprocket or a new sprocket alone. Otherwise, it will cause poor engagement and accelerate the wear of new sprocket or new sprocket. When the tooth surface of the sprocket is worn to a certain extent, it shall be turned over in time (referring to the sprocket used for adjustable surface) to prolong the service time.
4. The new sprocket is too long or elongated after use, which is difficult to adjust. The chain links can be removed according to the situation, but they must be even. The chain link shall pass through the back of the sprocket, the locking plate shall be inserted outside, and the opening of the locking plate shall face the opposite direction of rotation.
5. The sprocket should be filled with lubricating oil in time during operation. The lubricating oil must enter the fit gap between the roller and the inner sleeve to improve the working conditions and reduce wear.
6. The old sprocket cannot be mixed with some new sprockets, otherwise it is easy to produce impact in the transmission and break the sprocket.
7. When the machine is stored for a long time, the sprocket should be removed and cleaned with kerosene or diesel oil, then coated with engine oil or butter and stored in a dry place.
