How to solve the problem of chain climbing and jumping teeth of chain and sprocket
roller chain jumps between the chain and the sprocket, but the chain jumps clockwise and smooth counter-wise. What is the reason? Is it biased? The maintenance personnel first check to see where the jump is. It is very likely that the chain is near the teeth of the chain. In this way, it is possible that the chain pitch does not match the chain and cannot be disengaged when it is time to take off. A worker said that one tooth might be crooked. But the current situation is: the chain will slowly climb on the front small chainring, and then all climb to the top of the tooth, and then fall into the root of the tooth with a bang. Then change the chain, it takes a long time to extend the chain, and the sprocket is grinding one side. Can't it be replaced with a new chain? The new chain and the old Gear plate are not coordinated and do not cooperate. It is also a problem. Someone suggested that the way to deal with it now is: ask the maintenance personnel to remove the chain, check the rotation of each section, add grease to lubricate, then remove the two sections, and try to shorten the chain length. The worker next to me said that shrinking is also possible...but the design chain we made is equipped with a tension adjustment device, and a small wheel is added in the middle, which is adjusted with a screw, which is more stable and reliable than the adjustment with a long hole.
