Problems solved by technology

[0003] In assembly and maintenance, for the bearings set in the deep hole, due to the limitation of the deep hole, it brings a lot of inconvenience to the disassembly of the bearing. Some factories use punches, tapered pins and other simple methods when disassembling the bearings. Forcible disassembly with tools, such disassembly will not only damage the bearing, but may also damage the product

Embodiment 1

[0011] Embodiment 1: as figure 1 As shown, a bearing extraction device, the device includes a bracket 4 and a removal head 1, the screw 2 is vertically arranged on the bracket, the screw 2 is connected to the bracket through a connecting piece 3, and the screw 2 The lower end is connected with the take-out head 1; the support 4 is a right triangle.

[0012] The present invention is used in this way: the pulling head 1 is penetrated into the inner ring of the bearing, the pulling head 1 is clamped with a wrench, and then the screw rod 2 is turned to expand the pulling head 1 and grasp the bearing, and then turn the right-angled triangle bracket 4 to surround the screw rod 2 Rotate to adjust the right-angled triangle bracket 4 to a suitable height, and finally use an air wrench to rotate the screw 2 to drive the puller 1 up to pull out the bearing. Because screw rod 2 is designed as two sections of oppositely rotating helical threads, the direction of rotation in the ascending ...

Abstract

The invention discloses a bearing taking-out device. The bearing taking-out device comprises a support (4) and a taking-out head (1), wherein a threaded rod (2) is vertically arranged on the support and connected with the support through a connecting piece (3), and the lower end of the threaded rod (2) is connected with the taking-out head (1). The bearing taking-out device has the advantages of being simple in structural design and convenient to use. Working staff can conveniently and rapidly take out a bearing by using the bearing taking-out device, so that assembling and maintaining efficiency are improved; meanwhile, the bearing taking-out device does not damage the bearing and a product, and improves maintenance quality.

Description

[0001] technical field [0002] The invention relates to an assembly maintenance tool, in particular to a bearing extraction device. Background technique [0003] In assembly and maintenance, for the bearings set in the deep hole, due to the limitation of the deep hole, it brings a lot of inconvenience to the disassembly of the bearing. Some factories use punches, tapered pins and other simple methods when disassembling the bearings. Forcibly disassembled with tools, such disassembly will not only damage the bearing, but may also damage the product. Contents of the invention [0004] The object of the present invention is to provide a bearing extracting device that can quickly disassemble the bearing without damaging the bearing and the product. [0005] The object of the present invention is achieved through such a technical solution, a bearing extraction device, the device includes a bracket and a removal head, a screw is vertically arranged on the bracket, and the s...
