How to maintain and maintain the chain

05-06-2020

1. There should be no skew and swing when the sprocket is 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 is 1 mm; when the center distance of the sprocket is more than 0.5 meters, the deviation is 2 mm. But it is not allowed to have the side phenomenon of friction sprocket teeth. If the two wheels are moved too much, it is easy to produce off-chain and accelerated wear. Pay attention to check and adjust the offset when replacing the sprocket.


   2. The tightness of the chain should be appropriate, too tight to increase power consumption, the bearing is easy to wear; too loose chain is easy to jump and off the chain. The tightness of the chain is: lifted or pressed 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 elongated after use, it is difficult to adjust, the chain link can be removed depending on the situation, but it must be an even number. The chain link should pass through the back of the chain, the locking piece should be inserted outside, and the opening of the locking piece should be in the opposite direction of rotation.


   4. After the sprocket wears seriously, the new sprocket and new chain should be replaced at the same time to ensure good meshing. It is not possible to replace new chains or sprockets alone. Otherwise, it will cause poor meshing and accelerate the wear of the new chain or new sprocket. After the sprocket tooth surface wears to a certain degree, it should be turned over in time (refer to the sprocket used for the adjustable surface). To extend the use time.


   5. The old lifting chain can not be mixed with some new chains, otherwise it is easy to produce impact in the transmission and break the chain.


   6. Remember to add lubricating oil to the chain in time. The lubricant must enter the matching gap between the roller and the inner sleeve in order to improve working conditions and reduce wear.
