Planetary reducer is widely used in industrial production. But at the same time, some problems will be exposed, including oil leakage of planetary reducer, which is a common but headache problem for staff from all walks of life. Let's talk about the cause of oil leakage of planetary reducer.
1. Pressure rise in oil tank
In the closed planetary reducer, each pair of gears will generate heat when they are meshed and rubbed. According to Boyle mallott's law, with the extension of operation time, the temperature in the reducer box will gradually increase, while the volume in the reducer box will remain unchanged, so the pressure in the box will increase, and the lubricating oil in the box will splash and sprinkle on the inner wall of the reducer box. Due to the strong permeability of oil, under the pressure in the box, where the seal is not tight, the oil will seep from.
2. Oil leakage caused by unreasonable structural design of reducer
If the designed reducer does not have a ventilation hood, the reducer cannot achieve pressure equalization, resulting in higher and higher pressure in the box and oil leakage of planetary reducer.
3. Excessive refueling
During the operation of the reducer, the oil pool is stirred severely, and the lubricating oil splashes everywhere in the reducer. If the amount of oil 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 will also be caused due to incomplete removal of dirt on the joint surface, improper selection of sealant, reverse installation of seals, untimely replacement of seals, etc.
The above is the reason for oil leakage of planetary reducer. In industrial production, oil leakage is inevitable. What the majority of industrial producers need to do is to pay attention at any time, pay attention at any time, avoid oil leakage accidents as much as possible and minimize industrial losses.
