Helical gear reducer is a novel reduction transmission device. Adopting the most optimized and advanced design concept of modular combination system, it has the characteristics of small size, light weight, large transmission torque, stable starting, and fine transmission ratio classification. So in use, what caused the oil leakage of the helical gear reducer?

1. The pressure in the fuel tank rises 　
In a closed reducer, each pair of gears meshing and friction will generate heat. According to Boyle Mario’s law, as the operating time increases, the temperature in the reducer will gradually increase, and the volume inside the reducer No change, so the pressure in the box will increase, and the lubricating oil in the box will be splashed on the inner wall of the reduction box. Due to the relatively strong oil permeability, under the pressure in the tank, where the seal is not tight, the oil will leak out from where.
　



2. Unreasonable structure design of reducer causes oil leakage 　
If the reducer is designed without a vent hood, the reducer cannot achieve pressure equalization, resulting in higher and higher pressure in the box and oil leakage.　


3. Too much fuel 　
During the operation of the reducer, the oil pool is greatly agitated, 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 on the shaft seal, joint surface, etc., resulting in leakage.


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