1. The pressure in the oil tank rises. In the closed reducer, each pair of gears will generate heat when they mesh and friction. According to Boyle mallott's law, with the extension of operation time, the temperature in the reduction box will gradually rise, while the volume in the reduction 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 reduction 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. The unreasonable structural design of the reducer causes oil leakage. For example, the designed reducer has no ventilation cover, and the reducer cannot achieve pressure equalization, resulting in higher and higher pressure in the box and oil leakage.
3. Too much oil is added. 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 dirt * * * on the joint surface, improper selection of sealant, reverse installation of seals, untimely replacement of seals, etc.
Oil leakage control of reducer oil leakage is a difficult problem perplexing many manufacturers. Here are some countermeasures to control the oil leakage:
Improved ventilation cap and inspection hole cover plate. An oil cup type breathable cap is made, and the original thin inspection hole cover plate is changed to 6mm thick. The oil cup type breathable cap is welded on the cover plate. The diameter of the breathable hole is 6mm, which is convenient for ventilation and realizes pressure equalization. When refueling, add oil from the oil cup without opening the inspection hole cover plate, so as to reduce the chance of oil leakage.
