Analysis and Solution of the Oil Leakage Problem in the Drive Axle Main Gearbox Housing
In this paper,the main gearbox housing of a drive axle was analysed for oil leakage at the joint surface during the endurance test of the load bearing system,based on the finite element method,the sealing performance of the main gearbox housing was analysed and the main cause of oil leakage was identified as the large misalignment of the joint surface leading to shearing of the sealant,and under the premise that the tooling could not be changed extensively,countermeasures were taken to reduce the misalignment of the joint surface and prevent the sealant from shearing.The improved solution was tested and verified,and no oil leakage occurred on the main reducer joint surface.The solution established has certain engineering application value for the prevention and solution of oil leakage in the main gearbox housing.
