Analysis of Causes of Leakage of Oil in Helical Gear Reducer

1. The pressure in the fuel tank rises in the closed reducer. When each pair of gears meshes with each other, friction is generated. According to the law of Boeing, with the lengthening of the running time, the temperature inside the gearbox is gradually increased. High, and the volume inside the reduction chassis does not change, so the pressure inside the box increases, and the lubricating oil in the box is splashed and sprinkled on the inner wall of the reduction chassis. Because the oil has a relatively high permeability, under the pressure inside the box, which one is not tightly sealed, the oil will seep out from there.

2. Unreasonable structural design of the reducer causes oil leakage. If the designed reducer does not have a hood, the reducer cannot achieve equal pressure, resulting in higher and higher pressure inside the tank and oil leakage.

3. If the refueling machine is too much, the oil pool is agitated very much. The lubricating oil splashes everywhere in the machine. 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 in the equipment maintenance, due to the incomplete removal of dirt on the bonding surface, or the improper selection of sealant, the direction of the seal is reversed, the seal is not replaced in time, etc. will also cause oil leakage
