How Should The Crane Chain Be Maintained And Maintained

1. The sprocket should be mounted on the shaft without skew and swing. In the same transmission component, the end faces of the two sprockets should be located in the same plane, and the allowable deviation of 1 mm when the center distance of the sprocket is below 0.5 meters, the allowable deviation of 2 mm when the center distance of the sprocket is above 0.5 meters. However, it is not allowed to have friction sprocket tooth side phenomenon, if the two wheels are shifted too much, it is easy to produce chain removal and accelerated wear. When replacing the sprocket, attention must be paid to checking and adjusting the offset.
2. The tightness of the lifting chain should be appropriate, too tight to increase power consumption, bearing easy to wear too loose chain easy to jump and chain off. The tightness of the chain is: lifted or pressed from the middle of the chain, the center distance of the two sprockets is about 2%-3%.
3. The new lifting chain is too long or elongated after use, difficult to adjust, depending on the situation to remove the chain, but must be even. The chain link should pass through the back of the chain, the lock plate is inserted on the outside, and the opening of the lock plate should face the opposite direction of rotation.
4. After the sprocket is seriously worn, the new sprocket and the new chain should be replaced at the same time to ensure good engagement. You can't just replace a new chain or a new sprocket alone. Otherwise, it will cause poor meshing to accelerate the wear of the new chain or new sprocket. Sprocket tooth surface wear to a certain extent should be used in time to turn over (refers to the adjustable surface of the sprocket). To extend the use time.
5. The old lifting chain can not be mixed with part of the new chain, otherwise it is easy to have an impact in the transmission and break the chain.
6. The lifting chain should remember to fill lubricating oil in time during the work. The lubricating oil must enter the matching gap between the roller and the inner sleeve in order to improve the working conditions to reduce wear.
