Abstract

A kind of shaft bearing replacer, including support, cross bar, threaded rod, transport persons or goods by cart, described support has screwed hole by proximal end, described cross bar two ends have corresponding screw thread respectively and are fixed on support, cross bar centre position is provided with screwed hole, and described threaded rod is threaded one end through this screwed hole, described in transport persons or goods by cart and be separately fixed on metal derby, threaded rod is fixed with locating piece through the circular hole in the middle of metal derby and at end and is connected, in metal derby upper end, nut is set, described in transport persons or goods by cart elastic component be set between the lower bent angle, described elastic component makes two to transport persons or goods by cart expansion one angle.By arranging an elastic component between transporting persons or goods by cart two, when use this puller dismounting bearing time, launch an angle between making two to transport persons or goods by cart due to the elastic force of elastic component, it is ensured that in use do not have two transport persons or goods by cart Guan Bi thus can not effectively dismantle the situation of bearing.

Description

Shaft bearing replacer
Technical field
This utility model relates to dismantling technology field, is specifically related to a kind of puller for bearing.
Background technology
Bearing is a kind of important spare part in plant equipment in the present age.Its major function is to support machinery rotary body, reduces Coefficient of friction in its motor process, and ensure its rotating accuracy.By the difference of motor element frictional property, bearing can be divided into rolling Dynamic bearing and the big class of sliding bearing two.Wherein rolling bearing is the most normalized, seriation, but its radial direction compared with sliding bearing Size, vibration and noise are relatively big, and price is the highest.Rolling bearing is typically by outer ring, inner ring, rolling element and retainer four part group Becoming, general bearing removal mainly by drawbench, dismounting nut and heating these three mode, uses special puller to grasp The when of work, as long as rotary handle gently, bearing will slowly be pulled out, bearing outer ring is carried out dismantlement work time Waiting, its puller used is to have certain requirement, it is ensured that the bent angle between the bipod of this puller is outwardly, Existing demounting tool the most usually occurs that bipod Guan Bi makes to disassemble work and can not effectively carry out.
Utility model content
Technical problem to be solved in the utility model is to overcome existing technological deficiency, it is provided that a kind of bearing removal Device.
Technical problem to be solved in the utility model uses following technical scheme to realize:
A kind of shaft bearing replacer, including support, cross bar, threaded rod, transports persons or goods by cart, and support has screwed hole, cross bar two by proximal end End has corresponding screw thread respectively and is fixed on support, and cross bar centre position is provided with screwed hole, and threaded rod is threaded one end and passes This screwed hole, the threaded rod other end is cylinder, is provided with open-work on threaded rod cylinder, and swing arm passes this open-work, Drive threaded rod to rotate on cross bar by swing arm and realize moving up and down of threaded rod.Transport persons or goods by cart and be separately fixed on metal derby, spiral shell Rasp bar is fixed with locating piece through the circular hole in the middle of metal derby and at end and is connected, and arranges nut in metal derby upper end, by fixed Position block makes metal derby move up and down with threaded rod and drive movement of transporting persons or goods by cart, and arranges elastic component, bullet transporting persons or goods by cart between lower bent angle Property part make two to transport persons or goods by cart expansion one angle, when using this puller dismounting bearing, first fixed support, adjust threaded rod suitable high to one Degree, two transport persons or goods by cart closes and inserts in bearing top circle, makes two to transport persons or goods by cart automatically and stretch out and rely on bottom of transporting persons or goods by cart under the effect of elastic component Bent angle prop up bearing top circle, then bearing removal is got off by rotating rod.
Elastic component can be spring or resilient sleeve.
The beneficial effects of the utility model are: by arranging an elastic component between transporting persons or goods by cart two, tear open when using this puller When unloading bearing, launch an angle between making two to transport persons or goods by cart due to the elastic force of elastic component, it is ensured that in use do not have Two transport persons or goods by cart Guan Bi thus can not effectively dismantle the situation of bearing.
Accompanying drawing explanation
Fig. 1 is this utility model schematic diagram.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, under Face combines and is specifically illustrating, and this utility model is expanded on further.
As it is shown in figure 1, a kind of shaft bearing replacer, including support 3, cross bar 4, threaded rod 1, transporting persons or goods by cart 6, support 3 is by proximal end Having screwed hole, cross bar 4 two ends have corresponding screw thread respectively and are fixed on support 3, cross bar 4 centre position is provided with screwed hole, screw thread Bar 1 is threaded one end and passes this screwed hole, and threaded rod 1 other end is cylinder, is provided with on threaded rod 1 cylinder Open-work, swing arm 2, through this open-work, drives threaded rod 1 to rotate on cross bar 4 by swing arm 2 and realizes moving up and down of threaded rod 1. Transport persons or goods by cart and 6 be separately fixed on metal derby 8, threaded rod 1 through the circular hole in the middle of metal derby 8 and at end fixing with locating piece 5 even Connect, nut 9 is set in metal derby 8 upper end, make metal derby 8 move up and down with threaded rod 1 and drive 6 shiftings of transporting persons or goods by cart by locating piece 5 Dynamic, transporting persons or goods by cart 6 elastic component 7 is set between lower bent angle, elastic component 7 makes two to transport persons or goods by cart 6 expansion one angles, uses this puller to tear open When unloading bearing, first fixed support 3, adjust threaded rod to a proper height, two transport persons or goods by cart 6 Guan Bis insert in bearing top circle, at bullet Property part 7 effect under make two to transport persons or goods by cart 6 automatically to stretch out and rely on the bent angle of 6 bottoms of transporting persons or goods by cart to prop up bearing top circle, then rotating rod will Bearing removal gets off.
Elastic component 7 can be spring or resilient sleeve.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.One's own profession Skilled person will appreciate that of industry, this utility model is not restricted to the described embodiments, described in above-described embodiment and description Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, this utility model is also Have various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model Claimed scope is defined by appending claims and equivalent thereof.
