Faults and Troubleshooting of Oil Leakage in the Drive Axle of Hydraulic Excavators
Oil leakage from the drive axle refers to the leakage of lubricating oil outside the drive axle housing, with obvious oil stains.
Cause analysis: Oil leakage is always caused by poor sealing. The main reasons for poor sealing are as follows:
(1) The mating surface of the shell mating parts is uneven, the connecting screws are loose or the sealing gasket is damaged.
(2) Oil seal damage (refer to the transmission description for the cause of damage) or wear of the journal, etc., leads to poor sealing and oil leakage.
(3) Oil leakage from threaded holes is mostly caused by loose screws or damaged threaded threads. Imported pump
2. Diagnosis and Elimination: Oil leakage from the drive axle can be directly observed. Based on the analyzed causes, targeted elimination should be carried out.
