Transmission Chain Maintenance Standards

The Transmission Chain is a very critical transmission structure in mechanical equipment, which affects the working performance and service life of the equipment. Therefore, it is very necessary to maintain the chain at ordinary times.

1. The sprocket should be installed on the shaft without skew or swing. The end faces of the two sprockets in the same assembly should be in 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 more than 0.5 meters, the allowable deviation is 2 mm. However, it is not allowed to rub the side of the sprocket tooth. If the two-wheel knitting is too large, it will easily cause chain disconnection and accelerated wear. When replacing the sprocket, check and adjust the offset.
2. The tightness of the chain should be appropriate. Too tight increases power consumption and bearings are easy to wear; too loose chain is easy to jump and fall off. The tightness of the chain is: lifted or pressed down from the middle of the chain, the center distance between the two sprockets is about 2%-3%.
3. The chain is too long or stretched after use, and it is difficult to adjust. You can remove the chain-link depending on 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 not possible to just replace a new chain or new sprocket alone. Otherwise, it will cause poor meshing and accelerate the wear of the new chain or new sprocket. When the tooth surface of the sprocket wears to a certain degree, it should be turned over and used in time (referring to the sprocket used with an adjustable surface). To extend the use time.
5. The old chain cannot be mixed with part of the new chain, otherwise, it is easy to have an impact on the chain and break the chain.
