The maintenance of the sprocket will be introduced to you. If you want to know this topic, please let me know: 1. The tightness of the sprocket should be appropriate, too tight will increase power consumption, and the bearing will be easy to wear; If the sprocket is too loose, it is easy to jump and fall off the chain.The tightness of the sprocket is: lifted or pressed down from the middle of the sprocket, which is about 2%-3% of the core distance between the two sprocket. 2. The sprocket should not swing or skew when installed on the shaft. The end faces of the two sprocket in the same transmission assembly should be in the same plane. When the core distance of the sprocket is less than 0.5 meters, the deviation can be 1 mm; in the sprocket When the core distance is above 0.5 meters, the deviation can be 2 mm.However, there must be no friction on the side surfaces of the sprocket teeth. If the deviation of the two wheels is too large, it will easily cause chain disconnection and accelerated wear. When replacing the sprocket, check and adjust the offset. 3. After the sprocket is severely worn, it should be replaced with a new sprocket at the same time to ensure good meshing.You can't just replace it with a new sprocket alone, otherwise it will cause poor meshing and accelerate the wear of the new sprocket. When the sprocket is worn to a certain degree, it should be turned over and used in time to extend the use time.
4. The new sprocket is too long or stretched after use, and it is difficult to adjust. You can remove the link depending on the situation, but it must be an even number. The chain link should pass through the back of the sprocket, the lock piece should be inserted outside, and the opening of the lock piece should be Towards the opposite direction of the drive.
5. The sprocket should be filled with lubricating oil in time during work, and the lubricating oil needs to enter the matching gap between the roller and the inner sleeve to change the working conditions and reduce wear.
6. The old sprocket cannot be mixed with part of the new sprocket, otherwise it is easy to have an 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, and then coated with oil or butter and stored in a dry place.
