Analysis of the Causes of Oil Leakage in the Helical Gear Reducer

The helical gear reducer is a novel reduction transmission device. Adopting the advanced design concept of optimization and modular combination system, it has the characteristics of small size, light weight, large transmission torque, smooth starting, and fine transmission ratio grading. So what is the reason for the oil leakage of the helical gear reducer during use?

Analysis of oil leakage causes

1. The pressure inside the fuel tank increases

In a closed gearbox, friction between each pair of gears generates heat. According to Boyle Malotte's law, as the operating time increases, the temperature inside the gearbox gradually increases, while the volume inside the gearbox remains unchanged. Therefore, the pressure inside the gearbox increases, and the lubricating oil inside the gearbox splashes onto the inner wall of the gearbox. Due to the strong permeability of oil, under the pressure inside the box, oil will seep out from wherever it is not tightly sealed.

2. Unreasonable structural design of the gearbox causing oil leakage

If the designed reducer does not have a ventilation hood, the reducer cannot achieve pressure equalization, resulting in increasing pressure inside the box and oil leakage.

3. Excessive fuel consumption

During the operation of the gearbox, the oil pool is stirred violently, and the lubricating oil splashes everywhere inside the machine. If the amount of oil added is too much, a large amount of lubricating oil will accumulate in the shaft seal, joint surface, etc., leading to leakage.

4. Improper maintenance process

During equipment maintenance, oil leakage can also occur due to incomplete removal of dirt on the joint surface, improper selection of sealant, reverse installation of sealing components, and untimely replacement of sealing components.
