Maintenance method of electric hoist chain

November 11, 2020

The chain of the electric hoist is an important part of the electric hoist, so it is very necessary to maintain the chain of the electric hoist. The following small series will explain the maintenance method of the electric hoist chain. 1. The lifting chain sprocket should be mounted on the shaft without skewing and swinging. In the same transmission assembly, the end faces of the two sprocket wheels 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 tightening of the lifting chain should be appropriate, too tight to increase power consumption, the bearing is easy to wear; too loose chain is easy to jump and unchaining. The degree of tightness of the chain is: lifted or pressed from the middle of the chain, and the center distance of the two sprockets is about 2% to 3%. 3, the new lifting 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 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 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 lifting chain can't be mixed with some new chains, otherwise it will easily cause impact in the transmission and break the chain. The lifting chain should remember to fill the lubricant in time. The lubricating oil must enter the matching gap between the roller and the inner sleeve to improve the working conditions to reduce the friction, so that the normal operation of the electric hoist can be ensured. The above is the whole method of the electric hoist chain maintenance method. Source: http://://news.chinawj.com. CN
