Abstract

The utility model relates to disassembly tools, in particular to a disassembly tool for a motor bearing, and belongs to the technical field of electromechanical equipment maintenance. The disassembly tool comprises a cross beam, connection columns and clamping boards, wherein one end of each connection column is fixedly provided with one clamping board, the other end of each connection column is connected to the cross beam in a sleeved mode, and a jack is fixed in the middle of the cross beam. The disassembly tool has the advantages that the stress area between the clamping board and the bearing are increased, the bearing is prevented from being damaged in a disassembly process, and the labor intensity of disassembly of the bearing is reduced through the cooperative use of the jack in the disassembly process.

Description

A kind of extracting tool of bearing of motor

Technical field

The utility model relates to a kind of extracting tool, is specifically a kind of extracting tool of bearing of motor, belongs to electromechanical equipment maintenance technology field.

Background technology

For guaranteeing motor even running in life cycle, need regularly to motor, safeguard, wherein to the dismounting of the bearing link that is absolutely necessary; In the prior art, conventional bearing extractor is that triangle is taken off son, and triangle is taken off on son and is provided with pin connection, during use, is not easy to regulate; And triangle takes off sub-Main Function in the outer ring of bearing, by retainer and ball, power is delivered on inner ring, in this case, because the decay of plastic deformation force is large, external force requires larger, has increased the labour intensity of dismounting; In addition, the gib head size that triangle is taken off sub-front end is larger, if the distance between oil cap and bearing hour cannot be used this instrument in bearing; The method of another kind of dismounting bearing is, first to bearing heating, the inner ring of bearing to be expanded, and then knock with sledgehammer, by bearing removal.Because bearing is often subject to high temperature, its Facing material lower hardness, easily enhance faster wear, causes bearing inner race to run circle heating and lost efficacy, and causes the event generation of electric machine chamber-sweeping etc.And, in the process of using sledgehammer to knock, easily there is the injuries such as object splashes, job safety coefficient is reduced.

Utility model content

Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, and a kind of extracting tool of bearing of motor is provided, and this instrument can drop to the labour intensity of motor disassembling minimum, and safety easy to use.

In order to solve above technical problem, the utility model provides a kind of extracting tool of bearing of motor, comprises crossbeam, joint pin and clamp, and clamp is fixed on one end of joint pin, and the other end of joint pin is socketed on crossbeam, at the middle part of crossbeam, is fixed with jack.

The technical scheme that the utility model further limits is:

Further, clamp end is provided with the arc notch matching with bearing curved surface.

Further, on joint pin, being socketed with U-shape lock tightly insures, the bottom of locking safety seal closed end is fixed on a joint pin by clamping screw, on two parallel hammerlocks of locking insurance openend, is respectively arranged with one group of adjustment hole, and between two groups of adjustment holes, position is mutually corresponding.

Further, at locking insurance openend, be provided with and can insert two groups of adjustment holes and fixing pin simultaneously.

The beneficial effects of the utility model are: the utility model has increased the lifting surface area between slip ring and bearing, avoid bearing to sustain damage in unloading process, coordinate the use of jack in unloading process, have reduced the labour intensity of dismounting bearing.

The specific embodiment

embodiment 1

The extracting tool of a kind of bearing of motor that the present embodiment provides, as depicted in figs. 1 and 2, comprise crossbeam 1, joint pin 2 and clamp 3, clamp 3 ends are provided with the arc notch matching with bearing curved surface, clamp 3 is fixed on one end of joint pin 2, the other end of joint pin 2 is socketed on crossbeam 1 and (in Fig. 1, only shows two joint pins 2, be appreciated that, four bights at crossbeam 1 are all provided with joint pin 2), at the middle part of crossbeam 1, be fixed with jack 4, jack 4 is positioned in the middle of two joint pins 2, on two joint pins 2, be socketed with the tight insurance 5 of U-shape lock, the bottom of locking insurance 5 blind ends is fixed on a joint pin 2 by clamping screw 6, on two parallel hammerlocks of locking insurance 5 openends, be respectively arranged with one group of adjustment hole 7, between two groups of adjustment holes 7, position is mutually corresponding, at locking insurance 5 openends, be provided with and can insert two groups of adjustment holes 7 and fixing pin 8 simultaneously, the setting of adjustment hole 7 is in order to adapt to the bearing of different sizes, after adjusting to suitable width, lock again, wide adaptability like this, use also safer.

As known to those skilled in the art, between above-mentioned joint pin 2 and crossbeam 1 and clamp 3, can be fixed together in several ways, for example, can, by casting integrated moulding, can also, as shown in the utility model, by welding, fix; The utility model does not limit these fixed forms, in addition, between crossbeam 1 and jack 4, is to fix by welding yet.

In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
