Abstract

This utility model discloses a differential bearing disassembly fixture, including a base and clamping rings, with a support plate welded to one side of the top of the base. By employing clamping rings and rubber pads, when the clamping rings move to the outside of the differential bearing, the operation of a second motor drives a second bidirectional screw to rotate, causing the clamping rings on both sides to abut against the surface of the differential bearing. Since the structure of the clamping rings is the same as that of the bearing, the clamping rings can fully cover the surface of the bearing, thus expanding the overall contact area. Compared to the traditional point contact method, this allows for a more even distribution of pressure, reducing the squeezing damage to the bearing during subsequent lifting and ensuring smooth subsequent use of the bearing. Furthermore, a rubber pad is provided between the clamping rings and the bearing for cushioning, further reducing operational damage and improving overall performance. It has the advantages of minimal disassembly damage and even force distribution.
