Abstract
It is an object of the invention to overcome defect present in prior art, design a kind of portable bearing removing device.This structure is mainly used in frame for movement industry.Not only save the time taking out bearing, improve work efficiency, and solve the problem that when existing bearing takes out, axle damages with the easy stress of bearing efficiently, thus improve the reuse ratio of bearing and axle.
Description
Technical field
The invention belongs to mechanical structure field, relate to a kind of portable bearing removing device.
Background technology
Along with the development of science and technology, various bearings constantly occur.Enjoy that they give simultaneously easily,
Various problems occur the most therewith.In mechanical structure field, how to realize while bearing can conveniently install, can facilitate again
Taking out bearing, and do not damage bearing, thus strengthen the utilization rate of bearing, this problem has obtained paying close attention to widely.Such as Fig. 1 institute
Showing, after existing bearing 1 is arranged on existing axle 2, if needing to take out bearing 1, then needing uniform percussion bearing 1 inner ring to reach
To the purpose taking out bearing 1.
Analyze the above-mentioned prior art mentioned to have the following disadvantages, i.e. the technical problem to be solved:
Due to bearing arrangement (as shown in Figure 1) bearing 1 need take out time need uniform percussion bearing 1 inner ring to take out bearing 1, this
Sample can consume the substantial amounts of time when taking out bearing 1, the most only taps this bearing 1 inner ring by operator's hand operation and is possible to lead
Cause to damage axle 2 surface when tapping, thus cause axle 2 surface to be worn and change axle 2；
When tapping bearing 1 inner ring, likely maloperation taps the outer ring of bearing 1 simultaneously, makes bearing 1 outer ring by outside bigger
Power is so that bearing 1 inner ring is destroyed by axial force with outer ring.
Summary of the invention
It is an object of the invention to overcome defect present in prior art, design a kind of portable bearing removing device.
This structure is mainly used in frame for movement industry.Not only save the time taking out bearing, improve work efficiency, and efficiently
Solve the problem that when existing bearing takes out, axle and the easy stress of bearing are damaged, thus improve the recycling of bearing and axle
Rate.
To achieve these goals, the technical scheme is that a kind of portable bearing removing device of design, including axle
Hold withdrawing device assembly, axle and bearing.
Wherein said bearing removing device assembly includes fixed underpan, ejects screw rod, claw, claw positioning sleeve and claw admittedly
Rationed marketing axle.
Described fixed underpan centre bore is screwed hole, and periphery is uniform stretches out three connecting plates；The described screw rod one end that ejects is
Screw rod, screw rod end has top, and the other end is equilateral hexagon structure；Described claw one end has circular hole, and the other end stretches out card
Boss is had on pawl；Described axle one end is fluted.
Its annexation is: described fixed underpan is attached by screw thread with the described screw rod that ejects；Described eject spiral shell
The other end pneumatic impact spanner band moving sleeve of bar carries out rotation and holds out against described axle；Described claw passes through claw steady pin
The connecting plate that axle is stretched with described fixed underpan is attached, and can rotate along described claw fixed pin shaft simultaneously；Institute
State claw positioning sleeve center pass described in eject screw rod, three projections are used for limiting three fixing described claws
Position, when ensureing to take out described bearing with this, three described claws can be stuck on described bearing inner race and not fall off.
Advantages of the present invention and having the beneficial effects that: have top on screw rod owing to ejecting described in bearing removing device of the present invention
Point, fluted on described axle, it is ensured that described in eject and will not push up partially when screw rod and described axle hold out against, described claw is at described bearing circle
Being uniformly distributed in the range of week, it is ensured that described bearing uniform force when being removed, convenient taking-up, described claw hook tip is divided into convex
Platform structure, it is ensured that when described claw takes out described bearing, stress point is on described bearing inner race, will not damage described bearing.

Detailed description of the invention
Being further described the detailed description of the invention of the present invention with embodiment below in conjunction with the accompanying drawings, following example are only used
In technical scheme is clearly described, and can not limit the scope of the invention with this.
As shown in Figure 2, Figure 3, Figure 4, the technical scheme is that a kind of portable bearing removing device of design, including axle
Hold withdrawing device assembly 21, bearing 22 and axle 23.
Described bearing removing device assembly 21 includes: fixed underpan 24, eject screw rod 25, claw 26, claw positioning sleeve 27
With claw fixed pin shaft 28.
Described fixed underpan 24 centre bore is screwed hole, and periphery is uniform stretches out three connecting plates；Described eject screw rod 25 1
End is screw rod, and screw rod end has top, and the other end is equilateral hexagon structure；Described claw 26 one end has circular hole, the other end
Stretch out and on claw, have boss；Described axle 23 one end is fluted.
Its annexation is: described fixed underpan 24 is attached by screw thread with the described screw rod 25 that ejects；Described top
Go out the other end pneumatic impact spanner band moving sleeve of screw rod 25 to carry out rotation described axle 23 is held out against；Described claw 26 passes through
The connecting plate that claw fixed pin shaft 28 is stretched with described fixed underpan 24 is attached, simultaneously can be along described claw steady pin
