Hub bearing press-fitting tool

Abstract

The invention provides a hub bearing press-fitting tool which solves the technical problems that after a bearing at an existing hub part is press-fitted, the service life of the bearing is shortened,and the occurrence of the failure at the hub part is caused. The hub bearing press-fitting tool is provided with an oil cylinder, a connecting screw, a transition block, an extension sleeve and an annular base plate, wherein a working end of a piston rod of the oil cylinder, the connecting screw and the transition block are arranged in the extension sleeve; a first internal thread hole is formed in the working end part of the piston rod of the oil cylinder and is adaptively connected with a screw-thread part of the connecting screw through a screw thread; a semi-opening limiting clamp slot isformed in the peripheral surface of one end part of the transition block along the radial direction, and is adaptively connected with the screw-thread part and the head part of the connecting screw ina clamping way; a second internal thread hole is formed in the other end part of the transition block; a T-shaped semi-opening is formed in one end part of the extension sleeve; the connecting screwcan penetrate through the T-shaped semi-opening so as to enter the extension sleeve; and the annular base plate is connected with the other end part of the extension sleeve. The invention can be widely applied to the press-fitting tools.

Description

technical field [0001] The invention relates to a pressing tool, in particular to a wheel hub bearing pressing tool. Background technique [0002] The traditional method of press-fitting the bearing at the wheel hub is generally to fix the inner ring of the bearing on the half shaft first, and then press-fit the bearing together with the half shaft in the hub. At this time, due to the high pressure, the inner ring of the bearing does not move. The force on the outer ring will cause pressing marks on the inner balls of the bearing, causing invisible damage to the bearing, which is not easy to detect, thus shortening the life of the bearing after pressing and causing failure at the hub. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies of the above-mentioned technologies, and provide a press-fitting tool for hub bearings, which can effectively protect the balls in the bearings by exerting force on the inner and outer rings o...
