Overhaul requirements and repair methods for gearbox differential housings

Gearbox differential housing repair requirements:

1. The gearbox differential housing is not allowed to have cracks of any nature. The contact between the shell and the planetary gear and the semi-axle gear washer should be smooth and free of grooves; the cooperation between the difference between the difference between the bearing and the journal at both ends of the differential should be In accordance with the regulations, the wear of the place shall not exceed 0.05mm. When it exceeds, the journal may be surfacing after welding or be veneered to restore the original fit size.

2. The clearance between the cross shaft hole of the gearbox differential housing and the cross journal should not be greater than 0.1mm, the shaft hole wear is more limited, and the transposition repair method can be used to change the position on the housing to re-machine the shaft hole according to technical requirements. To restore the original cooperation requirements.

3. The gearbox housing of the gearbox differential housing and the half shaft gear journal can not exceed 0.25mm.

Gearbox differential housing repair method:

1. The neck wear of the roller bearing at both ends of the differential shall not exceed 0. 05mm. If it exceeds, the inner ring of the bearing may be chrome-plated, or the neck may be welded or inlaid.

2. When the contact surface of the differential housing and the planetary gear has slight wear, it can be ground.

3. The wear of the cross shaft hole of the differential housing shall not exceed 0.7 0mm. When surpassing, the welding end face should be repaired. The contact end surface of the differential housing and the semi-axle gear should be smooth. If it is slightly grooved, it can be repaired.

4. After the differential housing and the planetary gear are in contact with the spherical surface, they can be repaired or repaired to repair size.
