SprocketsMaintenance and upkeep:
1. The sprocket tension should be appropriate. Too tight a tension will increase power consumption and cause the bearings to wear easily; too loose a tension will cause the sprocket to jump and derail. The appropriate sprocket tension is: when the sprocket is lifted or pressed down from the middle, it should be approximately 2%-3% of the center distance between the two sprockets.
2. The sprockets should be mounted on the shaft without any wobble or misalignment. In the same transmission assembly, the end faces of the two sprockets should be in the same plane. When the center distance between the sprockets is less than 0.5 meters, a deviation of 1 mm is acceptable; when the center distance is greater than 0.5 meters, a deviation of 2 mm is acceptable. However, there should be no friction between the sprocket teeth sides. Excessive misalignment between the two sprockets can easily lead to chain slippage and accelerated wear. When replacing sprockets, it is essential to check and adjust the misalignment.
3. When the sprocket is severely worn, both the sprocket and the new sprocket should be replaced simultaneously to ensure proper meshing. Do not replace only the sprocket or the new sprocket. Otherwise, poor meshing will accelerate the wear of the new sprocket or the new sprocket. Once the sprocket teeth are worn to a certain extent, they should be flipped over for use (referring to sprockets with adjustable teeth) to extend their service life.
4. If a new sprocket is too long or has stretched after use and is difficult to adjust, chain links may be removed as needed, but the number of links must be even. The chain links should pass through the back of the sprocket, with the locking plate inserted on the outside, and the opening of the locking plate should face the opposite direction of rotation.
5. Lubricating oil should be added to the sprocket in a timely manner during operation. The lubricating oil must enter the clearance between the roller and the inner sleeve to improve working conditions and reduce wear.
6. Old sprockets should not be mixed with some new sprockets, otherwise impacts may occur during transmission, causing the sprockets to break.
7. When storing the machine for a long time, the sprocket should be removed and cleaned with kerosene or diesel oil, then coated with machine oil or grease and stored in a dry place.
