Analysis of the Reasons for the Increase of Oil Pressure in the Gearbox

时间:2019-03-19 15:30   tags: Technology Frontier  

        In a closed reduction gearbox, each pair of gears mesh with each other and generate heat.According to Bower's law, as the running time increases, the temperature inside the gearbox gradually increases and the gearbox decreases.The volume does not change, so the pressure in the box increases, and the lubricating oil in the box splashes and spills on the inner wall of the reduction box.Because oil has relatively high permeability, under the pressure in the tank, which one is not tightly sealed, the oil will seep out from there.
        1. The structure design of the reducer is unreasonable, causing oil leakage.
        If the designed reducer does not have a cover, the reducer cannot reach equilibrium, resulting in higher and higher pressure in the tank and oil leakage.
        2. Too much oil
        During the operation of the reducer, the oil pool is stirred a lot, and the lubricating oil splashes around 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.
        3. Improper maintenance process
       During equipment maintenance, due to the incomplete removal of dirt on the bonding surface, improper sealant selection, reverse positioning of the seal and failure to replace the seal in time, oil leakage may occur.
