The structure of the drive axle is very complicated. It is generally composed of a reducer, a differential, a half shaft and an axle housing. Due to high-speed operation during work, it bears a large load, transmits a large torque, and wears a large part of the surface. Therefore, in order to prevent the early wear and damage of the drive axle parts, the maintenance of the drive axle is very important. We divide the maintenance work into primary maintenance and secondary maintenance. The following will explain in detail for you.

1. During the first-level maintenance of the drive axle, the following maintenance operations should be performed on the drive axle:

(1) Check the rear axle housing for cracks and abnormal leakage. If there is leakage, the cause should be found out and eliminated. ...

(2) Check whether the connection of each bolt and nut is reliable. ...

(3) Whether the amount of lubricating oil in the rear axle housing is appropriate, the oil level should not be lower than 15mm from the lower edge of the inspection hole. To

(4) The vent plug of the rear axle housing should be kept unblocked. ...

(5) When checking the tightness of the bearing by pushing the hub, there should be no obvious looseness in the hand. ...

(6) Check that the exposed bolts and nuts on the tires and axle shafts must not be loose. ...

2. In addition to all items of the first-level maintenance for the secondary maintenance of the drive axle, the following should be carried out:

(1) Check the half shaft. There should be no bending or cracking of the half shaft, and no excessive wear of the keyway. If there is visible keyway wear, the left and right half shafts should be transposed. ...

(2) Remove the hub and check whether the half-shaft sleeve is loose or cracked. The damage of each thread shall not exceed 2 teeth. ...

(3) Check for cracks in the rear axle housing. ...

(4) After draining the oil, remove the rear axle housing cover, remove the oil and check the tightness of gears, bearings and various bolts, and replace gears and bearings if necessary. ...

(5) Check whether the oil seal of the main reducer is leaking, whether the flange nut is loose, and check the tightness of the connecting bolts of the main reducer. ...

(6) Check the tightening of the wheel hub bearings, and tighten them according to the technical requirements if necessary. ,

(7) Whether there is abnormal noise in the main reducer, and whether the meshing gap of the main reducer is too large; if so, it means that the gear teeth are worn or the meshing gap is too large, and the meshing gap should be adjusted and the tooth surface joining condition should be adjusted. ...

(8) Check whether the oil temperature of the rear axle during normal operation exceeds 60°C with abnormal noise. If this phenomenon occurs, it means that the gear teeth are not properly meshed or the gear has broken teeth. It may also be due to excessive bearing preload. The final drive and differential should be disassembled and inspected. To

The time for primary maintenance and secondary maintenance depends on how often the enterprise uses the drive axle, but it must be regular and comprehensive. After the above-mentioned maintenance work is completed, the rear axle housing rear cover should be installed, and the gear oil that meets the original factory regulations should be filled to the specified oil level according to the regulations. After the inspection is correct, it can continue to be put into use.
