Embodiment 1

[0031] A versatile bearing removal tool such as Figure 1-2 As shown, it includes a bar 1, a force block 2 sleeved on the bar 1, a push rod 3, a fixing piece 4, a left connecting rod 5, a right connecting rod 6 and a first clamping rod provided with several positioning holes 9 7 and the second lever 8;

[0032] The rod 1 includes a vertical part and a horizontal part that is vertically arranged at the top of the vertical part and extends to both sides; Falling off; the bottom end of the vertical part of the rod 1 is provided with threads, and the rod 1 and the ejector rod 3 are connected through the screw sleeve 12;

[0033] The outer surface of the push rod 3 is threaded; the fixing part 4 is sleeved on the push rod 3, and the push rod 3 at both ends of the vertical direction of the fixing part 4 is provided with a nut 14 for limiting the movement of the fixing part 4; The nut 14 locks the position of the fixing part 4, and the position of the fixing part 4 can be adjusted ...

Embodiment 2

[0043] A versatile bearing removal tool such as image 3 As shown, the clamping member 15 is hook-shaped; the clamping member 15 is detachably connected with the first clamping rod 7 and the second clamping rod 8 through bolts; the bolt passes through the vertical end of the clamping member 15 The through holes connect the clamping member 15 with the first clamping rod 7 and the second clamping rod 8 .

[0044] In this embodiment, the multi-purpose bearing removal tool is used to disassemble bearings of different sizes. The specific steps are as follows:

[0045] 1. Cross-hinge the first clamping rod 7 and the second clamping rod 8 on the pin shaft 13 at the end of the ejector rod 3, and adjust the direction of the bottom clamping piece according to the type of the bearing 11 to be disassembled: when the base shaft is removed, the installation For bearings, place the outwardly bending clamp 15 at the bottom; when dismounting the bearing installed in the base hole system, rota...

Abstract

The invention belongs to the technical field of bearing dismounting tools, and particularly relates to a multi-purpose bearing dismounting tool. The multi-purpose bearing dismounting tool comprises ahandle rod, a force applying block arranged on the handle rod in a sleeving mode, a push rod, a fixing piece arranged on the push rod in a sleeving mode, left and right connecting rods, and a first clamping rod and a second clamping rod which are both provided with a plurality of positioning holes; the handle rod comprises a vertical part and a horizontal part, and the inner diameter of the forceapplying block is smaller than the length of the horizontal part of the handle rod; two ends of the fixing piece in the horizontal direction are correspondingly and movably connected to one ends of the left connecting rod and the right connecting rod; the first clamping rod and the second clamping rod are detachably connected to the other ends of the left connecting rod and the right connecting rod correspondingly; and the first clamping rod and the second clamping rod are hinged to the push rod in a cross mode through a pin shaft, and clamping pieces for clamping bearings are arranged at theends of the first clamping rod and the second clamping rod. The multi-purpose bearing dismounting tool can dismount the bearings with different sizes and types, and has a simple structure and convenient operation.

Description

technical field [0001] The invention belongs to the technical field of bearing removal tools, and in particular relates to a multi-purpose bearing removal tool. Background technique [0002] Bearing is a common component in the mechanical technology field. The bearing is sleeved on the machine body or pipe fittings, and needs to be disassembled and replaced after a certain period of use. [0003] According to the type of installation and fit, bearings can be divided into hole-based bearings and shaft-based bearings. The bearing made of the base hole is fixed on the rod-shaped part through the interference fit of the inner ring; the bearing made of the base shaft is fixed in the shaft hole through the interference fit of the outer ring. Traditional bearing dismounting tools can be used for bearings installed on the base hole system by knocking off or using ordinary dismounting tools such as pullers; but for bearings installed on the base shaft system, there are currently few...
