Abstract

The invention discloses a differential bearing mounting device with a bilateral bearing self-centering function. The differential bearing mounting device comprises upper-side self-centering bearing clamping mechanisms, lower-side self-centering bearing clamping mechanisms and a bottom plate; the lower ends of a left upright column and a right upright column are fixed to the bottom plate; a differential carrier plate and a pressure plate are in sliding connection with the left upright column and the right upright column; the cylinder fixing plate is fixed to the left upright column and the right upright column; a lifting cylinder is fixed to the cylinder fixing plate; a mandrel and the pressure plate are fixed with a piston rod of the lifting cylinder; a bearing fixing seat is fixed to thepressure plate; the bearing fixing seat and the mandrel are provided with a cylindrical cavity for accommodating an upper-side bearing; the upper-side self-centering bearing clamping mechanisms are arranged on the bearing fixing seat; the lower-side self-centering bearing clamping mechanisms are arranged on the bottom plate; the differential carrier plate is provided with a structure for fixing adifferential and an upper-side bearing lifting mechanism; the left upright column is provided with a left compression spring between the differential carrier plate and the bottom plate; and the rightupright column is provided with a right compression spring between the differential carrier plate and the bottom plate. The self-centering fixing of the upper-side bearing and a lower-side bearing ofthe differential is realized, and the mounting of the bilateral bearings of the differential is simpler and more convenient.

Description

technical field

[0001] The invention relates to a differential gear bearing installation device and an installation method with double-side bearing self-centering, and belongs to the technical field of differential gear tooling. Background technique

[0002] The protruding cylinders at both ends of the vehicle differential require bearing rotation support. In order to improve the reliability of the differential support and the rotation accuracy during operation, the inner holes of the bearings at both ends and the outer cylindrical surface of the differential adopt an interference fit. Smaller enterprises usually use manual assembly, which is inefficient and difficult to ensure assembly accuracy. Before the bearing is installed at the end of the differential, it needs to be fixed in advance. The efficiency of the screw drive clamping mechanism is low, and the magnetic suction is adopted The method is easy to attract the bearing to the deflection, and the bearing is pressed i...
