Drive Chain Maintenance Details
What are the precautions for maintenance of Drive Chain ?
1. The sprocket should be installed on the shaft and must not tilt or swing. The end faces of the two sprockets in the same gearbox assembly of the chain manufacturer should be on the same plane. When the center distance of the sprocket is less than 0.5 meters, the allowable deviation is 1 mm; when the center distance of the sprocket is greater than 0.5 meters, the allowable deviation is 2 mm. However, it is not allowed to rub the sides of the sprocket teeth. If the two-wheel knitting is too large, it is easy to cause the chain to break and accelerate wear. When replacing the sprocket, check and adjust the offset.2. The tightness of the chain should be appropriate. Too tight will increase power consumption and the bearings will wear out easily; too loose the chain will easily trip. The tightness of the chain is as follows: lifting or pressing down from the middle of the chain, the center distance between the two sprockets is about 2%-3%.3. The new chain is too long or stretched after use, and it is difficult to adjust. You can delete the chain link according to the situation, but it must be an even number. The chain link should pass through the back of the chain, the lock piece should be inserted outside, and the opening of the lock piece should face the opposite direction of rotation.4. After the sprocket is severely worn, the new sprocket and the new chain should be replaced at the same time to ensure good meshing. It is impossible to just replace a new chain or a new sprocket. Otherwise it will cause poor meshing and accelerate the wear of the new chain or new sprocket. When 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 with adjustable surface) to extend the use time.5. The old chain cannot be mixed with a part of the new chain, otherwise it will easily affect the transmission and damage the chain.6. During work, the chain should be filled with lubricant in time. Lubricant must enter the matching gap between the roller and the inner sleeve to improve working conditions and reduce wear.
