Kong Zhong；The diameter of axle cooperation of the semicircle orifice and two tapered roller bearings 7 of two differential bearing lids 2, the end of differential bearing lid 2
Face and the end face of reducing gearbox 1 cooperate, and the semicircle orifice of differential bearing lid 2 and the semicircle orifice of reducing gearbox 1 constitute the first circular hole,
Screw thread is processed on the first circular hole, for connecting adjustment ring 6；Reducing gearbox 1 and differential bearing lid 2 pass through four the first bolts
3 connections；The reducing gearbox 1, uses the second borehole structure on the lateral surface of semicircle orifice, and retarder is inserted into one end of locking plate 4
In second circular hole of shell 1, the circular hole among locking plate 4 is aligned with the threaded hole of reducing gearbox 1, and the other end is inserted into point of adjustment ring 6
In cloth groove；Locking plate 4 is connect with reducing gearbox 1 by the second bolt 5.
Further, the locking plate 4, using stamping steel plate structure, one end uses crotch structure, is used for and reducing gearbox 1
The cooperation of the second circular hole, the other end uses straight tooth structure, and for connecting adjustment ring 6, centre uses borehole structure, connects for bolt
Connect reducing gearbox 1.
Compared with prior art, as follows the advantages of the utility model:
A kind of Novel differential gear bearing locking structure of the utility model, locking plate one end use crotch structure, and centre uses
It is singly bolted, reduces the weight and cost of locking plate；Locking plate is fixed on the side of reducing gearbox and differential case bearing bracket, cancels
The locking plate connection structure that differential bearing covers, reduces the weight and cost of differential bearing lid.
