Maintenance knowledge of transmission chain?

The Transmission Chain is a very critical transmission structure in mechanical equipment, which affects the equipment’s working performance and service life. Therefore, it is indispensable to maintain the chain in 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;

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 chain’s tightness is lifted or pressed down from the middle of the chain, and the center distance between the two sprockets is about 2%-3%.

3. The chain is too long or stretched after use, making it 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 simultaneously to ensure good meshing. It is not possible to replace a new chain or new sprocket alone. Otherwise, it will cause poor meshing and accelerate the wear of the new chain or sprocket.

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.
