What Is The Cause Of Oil Leakage Of Planetary Gear Motor?

Planetary gear motor oil leakage will not only cause unnecessary waste, but also damage the gear motor. So we have to regularly check the gearbox to prevent it from oil leakage but not found in time, so what are the causes of oil leakage from the gearbox? Let's learn more about the following.

1. improper inspection process, such as equipment maintenance surface cleaning is not complete, improper selection of sealant, the wrong direction of seal installation, seal replacement is not timely, etc., will lead to oil leakage.

2. When the gearbox of the reducer is running, the heat generated by each pair of gears meshing in the box increases with the running time. This causes the box temperature to rise and the volume to expand. If the ventilation cover is not opened so that the thermally expanded air inside the box can be discharged freely to keep the pressure balance inside and outside the box, otherwise the lubricating oil will leak along the sub-box surface or other gaps such as shaft extension seals.

3. The amount of refueling is too large, when the reducer is running, the oil pool is stirred violently, causing the lubricant to splash to all corners of the machine. If the refueling quantity is too large, a large amount of lubricating oil will accumulate in the shaft seal, bonding surface and other places, causing leakage.

4. The pressure difference inside and outside the reducer, during the operation of the reducer, the frictional heat of the moving parts and the influence of the ambient temperature make the temperature of the reducer rise, if there is no air permeation hole or the air permeation hole is blocked, the pressure inside the machine gradually increases, the higher the temperature inside the machine, the greater the pressure difference with the outside world, and the lubricant leaks out from the gap under the action of the pressure difference.

5. The structure of micro gear box is not well considered, the inspection hole cover plate is too thin, and it is easy to deform when tightening the bolt, resulting in uneven combination surface and oil leakage from the contact gap. As the castings are not aged or annealed during the whole production process of the gear box, the internal tension is not eliminated, deformation and gap generation are inevitable, which leads to leakage. Due to the lack of oil return groove in the box, the lubricating oil accumulates in the shaft seal, end cover and bonding surface, etc., and the lubricating oil leaks from the gap due to the pressure difference.
