Press mounting device for bearing of rear axle differential of small vehicle

Abstract

The invention provides a press mounting device for a bearing of a rear axle differential of a small vehicle. The device comprises a bracket; a horizontally-arranged supporting plate is fixed to the upper surface of the bracket; the lower ends of a first vertical column and a second vertical column are respectively fixed to the left end and the right end of the upper surface of the supporting plate, wherein the first vertical column and the second vertical column are vertical and arranged in parallel, and the first vertical column and the second vertical column are glidingly connected with two ends of a differential fixing plate and a downward-pressing plate from bottom to top in a sequence; the upper ends of the first vertical column and the second vertical column are fixedly connected with a cylinder fixing plate; a cylinder of which a piston rod downwards extends out is fixed to the cylinder fixing plate; the downward-pressing plate and a fixing device for the bearing at the upper side of the differential are fixed below the piston rod of the cylinder; a second circular through hole for mounting the differential is formed in the differential fixing plate; a bearing fixing seat for mounting a pressing-in bearing at the lower side of the differential is fixed to the supporting plate. The device is simple in structure, and small in cost; the efficiency of press-mounting of the bearing of the differential can be improved.

Description

1. Technical field [0001] The invention relates to a differential bearing pressing device, in particular to a small vehicle rear axle differential bearing pressing device. 2. Background technology [0002] The differential is widely used because of its advantages of achieving different speeds of the two wheels during the turning process of the vehicle, improving the turning speed of the vehicle and protecting the tires. The differential needs to rotate in the axle housing, and support bearings need to be installed at both ends, and the bearings The inner hole and the outer cylindrical surface where the differential needs to be installed are usually connected by interference, and are usually installed by manual knocking, especially in small vehicle manufacturers. Not only is the efficiency low, but the force acting on each part of the bearing is uneven, which is easy Cause damage to the outer cylindrical surface of the differential installation part. Even if some bearings are...
