Analysis of the cause of oil leakage of electric hoist reducer

Electric hoist prone to some common failures, before we have introduced, today mainly introduces the reducer oil leakage problem, in order to solve the problem, we must first find out the cause of the problem, the main reasons are the following three points:

1.Between the reducer box and the box cover, the sealing ring is poorly assembled or damaged, should be removed to repair or replace the sealing ring;

2.The reducer connection screw is not tightened, after the shutdown, should tighten the screw.

3.Electric machine sweep: motor shaft support ring wear serious, rotor core displacement, or for other reasons to make the stator core displacement, resulting in the motor conical rotor and stator gap is too small to sweep, the motor is strictly prohibited "sweep", when the sweep occurs, should remove the support ring for a change, adjust the gap between the stator rotor cone surface to make it uniform, or sent to the maintenance factory for repair. Through the analysis of the common faults and treatment of the electric hoist, the electric hoist maintenance personnel know where to start the inspection when dealing with the fault, improve the maintenance efficiency, in addition, but also for the operator to provide on-site methods to deal with the problem.
