The stainless steel lifting chain can adjust the length of the chain according to the lifting height of the lifting object. It is an indispensable and important lifting device for cranes. It plays an important role in improving the operating efficiency of the crane and expanding the operating range of the crane. Then Transmission Chain Manufacturers will introduce how to maintain and maintain the crane chain?

1. The sprocket should be installed on the shaft without skew or 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 meters, the allowable deviation is 1 mm. When the center distance of the sprocket is more than 0.5 meters, the allowable deviation is 2 mm. However, it is not allowed to rub the side of the sprocket teeth. If the two-wheel knitting is too large, it is easy to cause chain disconnection and accelerated wear. When replacing the sprocket, check and adjust the offset.
2. The tightness of the lifting chain should be appropriate. Too tight increases power consumption, bearings are easy to wear, and too loose. The chain is easy to jump and fall off. The tightness of the chain is: lifted or pressed down from the middle of the chain, the center distance between the two sprockets is about 2%-3%.
3. The new lifting chain is too long or stretched after use, which is 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 at the same time to ensure good meshing. It is not possible to just replace a new chain or a new sprocket alone. Otherwise it will cause poor meshing and accelerate the wear of the new chain or new sprocket. When the tooth surface of the sprocket is worn to a certain degree, it should be turned over and used in time (referring to the sprocket used with adjustable surface). To extend the use time.
5. The old lifting chain cannot be mixed with part of the new chain, otherwise it is easy to produce an impact in the transmission and break the chain.
6. Remember to fill the lubricating oil in time when the lifting chain is working. The lubricating oil must enter the matching gap between the roller and the inner sleeve to improve working conditions and reduce wear.

Through the above introduction, Agricultural Chain Manufacturers hopes that you can simply refer to the content of this article in future use.
