An electric tricycle rear axle differential double-side bearing installation device

Abstract

The invention provides an installation device for bilateral bearings of a rear axle differential of an electric tricycle. The installation device comprises a support. A supporting plate is fixed to the upper surface of the support. The left end and the right end of the upper surface of the supporting plate are fixedly provided with the lower end of a first stand column and the lower end of a second stand column respectively, wherein the stand columns are vertical and parallel. An air cylinder fixing plate is fixed to the upper end of the first stand column and the upper end of the second stand column. A differential fixing plate is fixed to the middle of the first stand column and the middle of the second stand column. A descending press plate is located between the differential fixing plate and the air cylinder fixing plate. The left side and the right side of the descending press plate are connected with the first stand column and the second stand column in a sliding manner. A first air cylinder with a first piston rod extending out downwards is fixed to the air cylinder fixing plate. The descending press plate and a differential upper bearing fixing device are fixed below the first air cylinder. A second vertically through round hole is formed in the differential fixing plate, and the differential is installed in the second vertically through round hole. A second air cylinder, an ascending press plate and a differential lower bearing fixing device are arranged below the differential fixing plate and are symmetrical with the first air cylinder, the descending press plate and the differential upper bearing fixing device.

Description

1. Technical field [0001] The invention relates to a differential gear bearing installation device, in particular to an electric tricycle rear axle differential gear double-sided bearing installation device. 2. Background technology [0002] Electric tricycles are widely used in people's production activities due to their high durability and low cost. The demand for the differential, the core component of the rear axle, is increasing. The differential needs to rotate in the axle housing, and support bearings need to be installed at both ends. The inner hole of the bearing and the outer cylindrical surface of the part where the differential needs to be installed are usually connected by interference. Due to the cost limitation of the electric tricycle industry, some companies use manual knocking to install, which is not only inefficient, but also the force acting on each part of the bearing is not enough. Even, it is easy to cause damage to the outer cylindrical surface of th...

[0002] Electric tricycles are widely used in people's production activities due to their high durability and low cost. The demand for the differential, the core component of the rear axle, is increasing. The differential needs to rotate in the axle housing, and support bearings need to be installed at both ends. The inner hole of the bearing and the outer cylindrical surface of the part where the differential needs to be installed are usually connected by interference. Due to the cost limitation of the electric tricycle industry, some companies use manual knocking to install, which is not only inefficient, but also the force acting on each part of the bearing is not enough. Even, it is easy to cause damage to the outer cylindrical surface of the differential installation part and affect the performance of the differential. Even if a few enterprises adopt automatic installation, the installation equipment is often complicated and the cost is high, which is difficult for users to accept economically.
