Abstract
The invention discloses a bearing disassembling tool. The bearing disassembling tool is composed of a supporting pipe and a supporting rod, wherein an axial groove is formed in the supporting pipe, internal threads are arranged in the supporting pipe, and external threads matched with the internal threads are arranged on the surface of the supporting rod. The bearing disassembling tool is simple in structure, and a bearing can be disassembled conveniently and smoothly.
Description
Technical field
The present invention relates to a kind of bearing extractor.
Background technology
Bearing is in mechanical transmission course, to work the parts of fixing and reducing load coefficient of friction, also can say, in the time that other parts produce relative motion each other on axle, is used for reducing the fixing parts of coefficient of friction and retainer shaft center in power transmission process.Bearing is a kind of very important parts in contemporary plant equipment.Its major function is supported mechanical rotary body, the mechanical load coefficient of friction in order to reduction equipment in transmission process.
During bearing uses, can wear and tear because of permanent load, so that cannot continue supported mechanical rotary body, so must change after using a period of time, but, back shaft in bearing is easily removed, and mechanical rotary body is not easy to separate with bearing, and particularly the position of some narrow spaces is all the more so, often can only take destructive dismounting to change, not only operation is wasted time and energy, and very easily damages mechanical rotary body, directly affects whole mechanical transmission mechanism.
In view of this, the inventor develops a kind of bearing extractor specially, and this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of bearing extractor, to conveniently, successfully dismantle bearing.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of bearing extractor, is made up of stay tube and strut, has axial groove on stay tube, has internal thread in stay tube, and strut surfaces has the external screw thread with stay tube screw-internal thread fit.
Described stay tube is made up of to fastening two radius.
The outer end of described stay tube has bothridium.
The length of described strut is greater than the length of stay tube.
The outer end of described strut has bar head.
The inner of described strut forms tapered tip.
The inner of described stay tube forms for the barb coordinating with bearing inner side.
Adopt after such scheme, the present invention is simple in structure, when use, stay tube is plugged in the endoporus of bearing, and coordinates by internal thread and external screw thread, strut is screwed in stay tube, make stay tube softened and with the endoporus of bearing firmly, closely cooperate, then, be pulled outwardly stay tube and strut, bearing can be pulled down from mechanical rotary body, be realized conveniently, successfully dismantle bearing.
Below in conjunction with drawings and the specific embodiments, the present invention is described in further details.

Label declaration
Stay tube 1, axial groove 11, internal thread 12, bothridium 13, barb 14, strut 2, external screw thread 21, bar head 22, tapered tip 23, bearing 3, mechanical rotary body 4, bearing platen 5.
Detailed description of the invention
As shown in Figure 1 to Figure 3, be a kind of bearing extractor that the present invention discloses, formed by stay tube 1 and strut 2.On stay tube 1, have axial groove 11, this axial groove 11 can outwards strut stay tube 1 and diameter becomes large, so as with bearing 3 close contacts, in stay tube 1, there is internal thread 12.Strut 2 surfaces have external screw thread 21, and this external screw thread 21 can coordinate with the internal thread of stay tube 1 12.Like this, when the present invention uses, stay tube 1 is plugged in the endoporus of bearing 3, and strut 2 is screwed in stay tube 1, make the softened endoporus with bearing 3 of stay tube 1 firmly, closely cooperate, then, be pulled outwardly stay tube 1 and strut 2, can be with dynamic bearing 3 to pull down from mechanical rotary body 4, realize conveniently, successfully dismantle bearing.
For easy disassembly, this embodiment has bothridium 13 in the outer end of stay tube 1, and the outer end of strut 1 has bar head 22.And the length of this embodiment strut 2 is greater than the length of stay tube 1, facilitate screwing togather of stay tube 1 and strut 2.The inner of this embodiment strut 2 also forms tapered tip 23, after facilitating strut 2 to be screwed in stay tube 1, can support on bearing platen 5.
As shown in Figure 4, stay tube 1 also can be made up of to fastening two radius, and effect is identical with embodiment mono-.
As shown in Figure 5, the inner of stay tube 1 can also form barb 14, and strut 2 is screwed into after stay tube 1, and barb 14 can catch on bearing 3 inner sides, is more conducive to bearing 3 to disassemble.
These are only specific embodiments of the invention, not the restriction to protection scope of the present invention.All equivalent variations of doing according to the mentality of designing of this case, all fall into the protection domain of this case.
