The transmission chain is a very important transmission structure in mechanical equipment, which affects the working performance and service life of the equipment. Therefore, it is very necessary to maintain the transmission chain at ordinary times. Here are some important points for everyone.
1. The sprocket should be mounted on the shaft without skew and swing. 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 m, the deviation is 1 mm. When the center distance of the sprocket is 0.5 m or more, the deviation is 2 mm. However, the side phenomenon of the friction sprocket tooth is not allowed, and if the two-wheel knitting is too large, the chain is easily broken and the wear is accelerated. Care must be taken to check and adjust the offset when changing the sprocket.
2. The tightness of the transmission chain should be suitable, too tight to increase power consumption, the bearing is easy to wear; too loose chain is easy to jump and unchain. The tension of the drive chain is: lifting or pressing from the middle of the chain, the center distance of the two sprockets is about 2% - 3%.
3, the transmission chain is too long or stretched after use, it is difficult to adjust, you can see the situation to remove the link, but must be even. The links should pass through the back of the chain, the locking tabs are inserted outside, and the opening of the locking tabs should be in the opposite direction of rotation.
4. After the sprocket wears seriously, the new sprocket and the new chain should be replaced at the same time to ensure good meshing. It is not possible to replace a new chain or a new sprocket alone. Failure to do so may result in poor engagement to accelerate the wear of the new or new sprocket. After the sprocket tooth surface wears to a certain extent, it should be turned over in time (refer to the sprocket used for the adjustable surface). To extend the use of time.
5. The old chain can't be mixed with some new chains, otherwise it will easily cause impact in the transmission and break the chain.
