Sprocket Maintenance

1. The tightness of the sprocket should be appropriate. If it is too tight, it will increase power consumption and the bearing will be easily worn; if it is too loose, the sprocket will easily jump and come off the chain. The tightness of the sprocket is as follows: lift or press down from the middle of the sprocket, which is about 2%-3% of the center distance between the two sprockets.

2. The sprocket should not swing and skew when installed on the shaft. In the same transmission assembly, the end faces of the two sprockets should be in the same plane. When the center distance of the sprockets is less than 0.5 meters, the deviation can be 1 mm; when the center distance of the sprockets is more than 0.5 meters, the deviation can be 2 mm. However, there must be no friction on the tooth side of the sprocket. If the two wheels are offset too much, it is easy to cause off-chain and accelerated wear. Care must be taken to check and adjust the offset when changing sprockets.

3. After the sprocket is severely worn, the new sprocket and the new sprocket should be replaced at the same time to ensure good meshing. You cannot just replace a new sprocket or a new sprocket alone. Otherwise, it will cause poor meshing and accelerate the wear of the new sprocket or the new sprocket. After the tooth surface of the sprocket is worn to a certain extent, it should be turned over and used in time (referring to the sprocket used on the adjustable surface) to prolong the service time.

4. The new sprocket is too long or elongated after use, making it difficult to adjust. You can remove the chain links depending on the situation, but it must be an even number. The chain link should pass through the back of the sprocket, the locking piece should be inserted outside, and the opening of the locking piece should face the opposite direction of rotation.

5. The sprocket should be filled with lubricating oil in time during work. Lubricating oil must enter the fitting gap between the roller and the inner sleeve to improve 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.
