Summary of causes of oil leakage in planetary reducers

1, the pressure in the fuel tank increases

In a closed planetary reducer, each pair of gears engages in friction and generates heat. According to Boyle's Law, as the operation time increases, the temperature inside the planetary reducer box gradually increases, while the volume inside the reducer box remains unchanged, so the pressure inside the box increases accordingly. The lubricating oil in the box is splashed and sprinkled on the inner wall of the reducer box. Since the permeability of oil is relatively strong, under the pressure inside the tank, oil will seep out wherever the seal is not tight.

2, oil leakage caused by unreasonable structural design of reducer

If the planetary reducer is designed without a ventilation cover, the reducer cannot achieve pressure equalization, causing the pressure in the box to become higher and higher, resulting in oil leakage.

3, too much fuel

During the operation of the planetary reducer, the oil pool is stirred very much, and the lubricating oil splashes everywhere in the machine. If the amount of oil is too much, a large amount of lubricating oil will accumulate in the shaft seal, joint surface, etc., causing leakage.

4, improper maintenance process

During equipment maintenance, oil leakage may also occur due to incomplete removal of dirt on the joint surface, improper selection of sealant, reverse installation of seals, failure to replace seals in time, etc.
