Abstract
The utility model discloses a kind of bearing extractor, is made up of, stay tube has axial groove, have internal thread in stay tube stay tube and strut, and strut surfaces has the external screw thread with stay tube screw-internal thread fit.The utility model structure is simple, can realize conveniently, successfully dismantle bearing.
Description
Technical field
The utility model relates to a kind of bearing extractor.
Background technology
Bearing rises fixing in mechanical transmission course and reduces the parts of load coefficient of friction, alternatively, when other parts produce relative motion each other on axle, is used for reducing the fixing parts of coefficient of friction in power transmission process and retainer shaft center.Bearing is a kind of very important parts in contemporary plant equipment.Its major function is supported mechanical rotary body, in order to reduce the mechanical load coefficient of friction of equipment in transmission process.
During bearing uses, can wear and tear because of permanent load, so that supported mechanical rotary body cannot be continued, 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, destructive dismounting often can only be taked 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 present inventor develops a kind of bearing extractor specially, and this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of bearing extractor, so as convenient, successfully dismantle bearing.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of bearing extractor, be made up of stay tube and strut, stay tube has axial groove, have internal thread in stay tube, 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 is formed for the barb with bearing fit inside.
After adopting such scheme, the utility model structure is simple, during 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, realize conveniently, successfully dismantle bearing.
Below in conjunction with drawings and the specific embodiments, the utility model 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 utility model discloses, be made up of stay tube 1 and strut 2.Stay tube 1 has axial groove 11, this axial groove 11 makes stay tube 1 outwards to strut and diameter becomes large, so as with bearing 3 close contact, there is in stay tube 1 internal thread 12.Strut 2 surface has external screw thread 21, and this external screw thread 21 can coordinate with the internal thread 12 of stay tube 1.Like this, when the utility model 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, dynamic bearing 3 can be with pull down from mechanical rotary body 4, realize conveniently, successfully dismantle bearing.
Conveniently dismounting, 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, is screwed into after in stay tube 1 can supports on bearing platen 5 to facilitate strut 2.
As shown in Figure 4, stay tube 1 also can be made up of to fastening two radius, and effect is identical with embodiment one.
As shown in Figure 5, the inner of stay tube 1 can also form barb 14, and after making strut 2 be screwed into stay tube 1, barb 14 can catch on inside bearing 3, is more conducive to bearing 3 to disassemble.
These are only specific embodiment of the utility model, the restriction not to protection domain of the present utility model.All equivalent variations done according to the mentality of designing of this case, all fall into the protection domain of this case.
