Reason of electric overhead crane reducer failure
time:Oct 19,2016
The reducer is an important safety component of electric overhead crane, which can effectively prevent the lifted object from falling, can help to smoothly start and stop, and plays an important role in improving the accuracy and safety of electric overhead crane. In the process of use, the reducer may have problems such as the braking force is too low, and the brake pad is smoked due to excessive temperature. The main reasons of these problems are as follows:
1. The brake wheel of reducer is seriously worn, resulting in insufficient braking force;
2. There is a partial peeling phenomenon on the brake belt, which reduces the braking force;
3. The main spring adjustment is not tight enough;
4. There is dust, oil and the like between the brake belt and the brake wheel;
5. There is a problem with the impeller of the hydraulic push bar and the reaction is not sensitive;
6. The distance between the brake and gasket is unreasonable;
7. The brake gasket is seriously detached.
8. The long-stroke electromagnet is stuck by other things and cannot work normally.
