Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] see Figure 1 to Figure 6 , a special disassembly device for automobile gearbox bearings, consisting of a conical ejector rod 1, an M33 nut, a puller 2, a split pull block 3 and a pull block clamp 4; the method of using the special disassembly device for automobile gearbox bearings, its The steps are:

[0030] Step 1: Align the puller 2 with the fixed shaft where the bearing 6 is to be disassembled;

[0031] Step 2: Put the end of the pulling tube 2 on the fixed shaft end of the bearing 6 to be disassembled;

[0032] Step 3: According to the different specifications of the bearing 6, select the corresponding semi-circular split pull block 3, clamp the radial end of the semi-circular split pull block 3 in the stop groove of the outer ring of the bearing 6, and clamp the other end in the pull tube 2 In the groove, the two pull blocks are closed ...

Abstract

The invention relates to a using method of a dismounting device special for vehicle transmission bearings. The dismounting device special for the vehicle transmission bearings is composed of a taper mandril, an M33 nut, a pull barrel, split type pull blocks and a pull block hoop; the dismounting device includes the using steps that the pull barrel is firstly aligned at a fixed shaft with the bearings needing to be dismounted; the end of the pull barrel is arranged at the end of the fixed shaft with the bearings needing to be dismounted in a sleeving manner; the corresponding semicircular split type pull blocks are selected according to the bearings in different specifications, the radial ends of the semicircular split type pull blocks are clamped into a bearing outer ring stopping groove, one ends are clamped into a pull barrel groove, and the two pull blocks are closed to form a round whole; then the mated pull block hoop is arranged on the semicircular split type pull blocks in a sleeving manner; the taper mandril is rotated clockwises, a taper tip of the taper mandril abuts against a center hole of the fixed shaft tightly; and finally, the taper mandril is rotated clockwises continuously, the pull barrel has axial displacement relative to the fixed shaft, the bearings arranged on the pull blocks in a sleeving manner axially move along with the pull barrel, and the aim of taking out of the bearings is achieved.

Description

technical field [0001] The invention belongs to the technical field of automobile gearboxes, and relates to a method for using a special dismounting device for automobile gearbox bearings. Background technique [0002] The gearboxes widely used in automobiles are mainly fixed-shaft gear gearboxes. The bearings installed on the fixed shafts are radially stressed, and the installation position is close to the transmission gear. The bearing on the fixed shaft generally adopts small, medium and small deep groove ball bearings or cylindrical roller bearings with stop grooves on the outer ring. When repairing and replacing various parts in the gearbox, it is necessary to remove the bearing on the fixed shaft. The original method is: [0003] 1. Use an ordinary three-jaw tensioner. There are two disadvantages in the use of this tensioner: 1. The claws can only be stuck in the stop groove of the outer ring of the bearing. Due to the small working surface of the claws and the shall...
