Reducer oil leakage has always been a concern in the industry, Today, Shenzhen High torque planetary geared electric motor manufacturer Xiaobian to introduce the cause of High torque planetary geared electric motor oil leakage problem.

1, High torque planetary geared electric motor fuel amount is too much: when the reducer is used, it will vigorously stir the oil pan, and the lubricating oil will be spread over the whole machine.

2. The structure design of High torque planetary geared electric motor is unreasonable.

3. There is no oil return tank in the box, and the lubricating oil accumulates in the shaft seal, end cap, joint surface, etc., and leaks from the gap under the action of pressure difference; The check hole cover is too thin, and it is easy to deform after tightening the bolt, resulting in uneven bonding surface and oil leakage in the contact gap.

4. In the manufacturing process of High torque planetary geared electric motor, the casting has not been annealed or aged, and the internal parts have not been removed. Inevitably, stress and deformation lead to gaps and leaks.

5, the shaft seal structure design is impractical. The early High torque planetary geared electric motor mainly used the oil groove and felt ring type shaft seal structure, and the felt was deformed by compression during assembly, and sealed the gap between the joint surfaces. If the contact between the journal and the seal is not ideal, the seal will quickly fail due to very low felt compensation. The oil tank has an oil return hole, but it is easy to block and it is difficult to obtain the oil return effect.

6, High torque planetary geared electric motor internal and external pressure difference: When we use the reducer, the temperature of High torque planetary geared electric motor will continue to rise because of friction heating and the impact of ambient temperature. If you do not use it correctly, the ventilation hole will be blocked, so the internal pressure of the machine will gradually increase. The internal temperature of the machine will also increase, and the greater the difference between the pressure and the outside world, the oil may leak.
