A sprocket is a wheel with cog-type buckle teeth, which is used to mesh with a block with an accurate pitch on a link chain or a cable. Follow the editor of ASA sprocket to learn about its maintenance!
1. The tightness of the sprocket should be appropriate. Too tight will increase power consumption and the bearings will wear out easily; too loose the sprocket will easily jump and fall off the chain. The tightness of the sprocket is: lifted or pressed down from the middle of the sprocket, about 2%-3% of the center distance between the two sprocket.
2. The sprocket should not swing or 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 sprocket is less than 0.5 meters, the deviation can be 1 mm; when the center distance of the sprocket is more than 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 two wheels offset too much, it will easily cause chain disconnection and accelerated wear. When replacing the sprocket, you must pay attention to check and adjust the offset.
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. It is not possible to replace only a new sprocket or a new sprocket alone. Otherwise it will cause poor meshing and accelerate the wear of the new sprocket or new sprocket. When the tooth surface of the sprocket is worn to a certain degree, it should be turned over and used in time (referring to the sprocket used with adjustable surface) to extend the use time.
