A thorough investigation into the causes of oil leakage in planetary reducers

In industrial production, planetary reducers are widely used. But at the same time, some problems will also be exposed. Among them, oil leakage is a common but troublesome problem for workers in all walks of life. 1. The pressure in the oil tank rises. In a closed reducer, each pair of gears meshes and generates heat due to friction. According to Boyle's Law, as the operation time increases, the temperature inside the reducer box gradually rises. 

High, but the volume inside the reducer box remains unchanged, so the pressure inside the box increases, and the lubricating oil in the box splashes onto 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. Unreasonable structural design of the reducer causes oil leakage. If the 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. Excessive refueling. During the operation of the reducer, the oil pool is agitated very much, and the lubricating oil splashes everywhere in the machine. If the refueling amount is too much, a large amount of lubricating oil will accumulate in the shaft seal, joint surface, etc., resulting in 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. In industrial production, oil leakage is inevitable. All industrial producers need to do is to pay attention and pay attention at all times to avoid oil leakage accidents as much as possible and minimize industrial losses.
