Embodiment Construction

[0029] In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and the following embodiments are used to illustrate the present invention , but are not intended to limit the scope of the present invention.

[0030] like figure 1 As shown in the figure, this embodiment provides a bearing removal device for removing two bearings (not shown in the figure) installed on both sides of the workpiece. In this embodiment, the PM of the driving gear in the gearbox is removed. The side bearing and PW side bearing are used as examples for detailed description. The workpiece refers to the driving gear in the gearbox, and the two bearings are the PM side bearing and the PW side bearing. This device is used to synchronously remove the PM side bearing and the PW side...

Abstract

The invention relates to a bearing removal device for removing two bearings mounted on a workpiece. The removal device comprises a base body, on which a support table for supporting the workpiece is installed, and on the base body Removably installed with a first withdrawal plugboard and a second withdrawal plugboard, the first withdrawal plugboard and the second withdrawal plugboard are respectively inserted into the gaps between the two bearings and the workpiece, the first withdrawal plug A withdrawal plugboard and a second withdrawal plugboard are connected to a driving mechanism, and the drive mechanism drives the first withdrawal plugboard and the second withdrawal plugboard to move synchronously in opposite directions to realize the withdrawal of the two bearings . The invention can simultaneously complete the unloading operation of the two bearings on both sides of the workpiece at one time, and only one operator can complete the installation of the device and the unloading of the bearing, which greatly improves the operation efficiency, saves the maintenance time and reduces the labor intensity. At the same time, it can also eliminate operation hazards, improve the utilization rate of personnel and equipment, and ensure the quality of maintenance.

Description

technical field [0001] The invention relates to a bearing withdrawing device, belonging to the technical field of special tools for machinery. Background technique [0002] In the process of returning the EMU to the factory for advanced repair, the gearbox needs to be disassembled and repaired, and the bearings on both sides of the driving gear must be disassembled. The traditional solution is for the operator to remove the short end (PW) bearing first, then manually handle it and then remove the long end (PM) bearing. There are the following problems in the traditional bearing unloading operation method: 1. The operation efficiency is low; 2. The operation risk factor is high; 3. The operation is difficult; 4. The utilization rate of personnel and equipment is low. At present, although there are many devices for withdrawing bearings in the prior art, they are limited to withdrawing one bearing at a time. SUMMARY OF THE INVENTION [0003] The main technical problem to be...
