Abstract

The invention discloses a bearing convenient to install. An inner ring (4) is provided with a cavity (4a), a working medium injection port (4b) and an open pore (4c) communicating with the cavity (4a), a piston (5), a fixed piece (6) fixedly connected with the piston (5), and an elastomer (7). By changing the pressure of a fluid working medium, the fixed piece (6) enclasps or releases a shaft, so that fixing and dismounting of the bearing can be conveniently completed; and after the working medium with relatively high specific heat is adopted, more heat produced in working of the bearing can be absorbed, so that the bearing can be better cooled.

Description

A kind of bearing easy for installation
Technical field
The present invention relates to field of bearings, particularly relate to a kind of bearing easy for installation.
Background technique
Rolling bearing has application as standard piece more in the bearing of various rotatable parts.But because bearing inner race and axle are interference fit when current bearing is installed, be generally by knocking or installing by the mode that press machine is pressed into, also have and bearing heating made its inner ring swell and then be inserted on axle.The handling of bearing inconvenience all very in a word.
Summary of the invention
In order to overcome above-mentioned defect and deficiency the invention provides following technological scheme: a kind of bearing easy for installation, described bearing comprises outer ring, rolling element, retainer, inner ring, described inner ring inside is provided with a cavity, described inner ring end face is provided with the working medium inlet be connected with described cavity, described working medium inlet can be closed, and the end face of the described inner ring at described working medium inlet its place not outstanding, described inner ring is provided with some boss outstanding to described cavity closest to the sidewall of stationary axle, described boss is provided with perforate, described perforate runs through the sidewall at described boss and place thereof, and communicate with described cavity, the piston matched with it is provided with in described perforate, described piston is fixed a piston rod, one elastomer sleeve is located on described piston rod, described elastomeric one end and the end contact described piston being connected piston rod, the other end withstands on described inner ring, described piston is fixedly connected with a fixed plate by piston rod, the shape of described fixed plate on the radial cross section of bearing is fan-shaped.
During installation, first by bearing housing on axle, because elastomeric effect makes piston be received in described perforate, therefore bearing can be enclosed within axle very easily, and end face bearing inner race not being arranged working medium inlet is overlapped with shaft shoulder face.Then in cavity 4a, injected the working medium of high pressure by described working medium inlet, because piston ejects by the pressure of working medium, elastomer is compressed, and fixed plate holds axle tightly, makes bearing be fixed on axle, is finally closed by working medium inlet.During dismounting, opened by working medium inlet, extracted out by the high-pressure working medium in cavity and cavity pressure is released, piston is regained in perforate under elastomeric effect, drives fixed plate to loosen axle, thus can be unloaded by bearing easily.
As preferably, the sprue that to match with it is provided with in described perforate, described sprue closes described perforate just, described sprue is provided with through hole, described piston rod passes and is fixedly connected with described fixed plate from described through hole, described elastomeric one end and the end contact described piston being connected piston rod, the other end withstands on described sprue.Be arranged so that the assembling of piston and elastomer and inner ring is more convenient like this.
As preferably, described elastomer can be spring or block rubber one of them.
Compared with prior art, the present invention has following beneficial effect: by arranging cavity, the working medium inlet communicated with cavity and perforate, piston, the fixed plate affixed with piston and elastomer on inner ring.By the pressure of alter working medium, fixed plate held tightly or loosen axle, thus completing the fixing of bearing and dismounting easily.Simultaneously after adopting the working medium that specific heat is higher, the heat produced when can also absorb more bearing working, thus bearing is better cooled.
Accompanying drawing explanation

Fig. 2 is the front view of the bearing in embodiment of the present invention when not being arranged on axle.
Fig. 3 is that the bearing in embodiment of the present invention faces whole-cutaway view when not being arranged on axle.
Fig. 4 is A portion enlarged view.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.A kind of bearing easy for installation, described bearing comprises outer ring 1, rolling element 2, retainer 3, inner ring 4, described inner ring 4 inside is provided with a cavity 4a, described inner ring 4 end face is provided with the working medium inlet 4b be connected with described cavity 4a, described working medium inlet 4b can close, and the end face of the described inner ring 4 at described working medium inlet 4b its place not outstanding, described inner ring 4 is provided with six boss 4ds outstanding to described cavity 4a closest to the sidewall of stationary axle, each boss 4d is equipped with perforate 4c, described perforate 4c runs through the sidewall at described boss 4d and place thereof, and communicate with described cavity 4a, the piston 5 matched with it is equipped with in each perforate 4c, described piston 5 is fixed with piston rod, one spring 7 is sheathed on described piston rod, also be threaded in each perforate 4c sprue 4e that to match with it, described sprue 4e closes described perforate 4c just, described sprue 4e is provided with through hole, described piston rod passes and is fixedly connected with fixed plate 6 from described through hole, the shape of described fixed plate 6 on the radial cross section of bearing is fan-shaped, one end and the end contact described piston 5 being connected piston rod of described spring 7, the other end withstands on described sprue 4e.
During installation, first by bearing housing on axle, the effect due to spring 7 makes piston 5 be received in described perforate 4c, and therefore bearing can be enclosed within axle very easily, and end face bearing inner race 4 not being arranged working medium inlet 4b is overlapped with shaft shoulder face.Then in cavity 4a, the hydraulic oil of high pressure is injected by described working medium inlet 4b, because piston 5 ejects by the pressure of hydraulic oil, spring 7 is compressed, and six fixed plates 6 hold axle tightly, make bearing be fixed on axle, finally working medium inlet 4b is closed.During dismounting, opened by working medium inlet 4b, the high pressure liquid force feed in cavity 4a extracted out and cavity pressure is released, piston 5 is regained in perforate under the effect of spring 7, drives fixed plate 6 to loosen axle, thus can be unloaded by bearing easily.
Compared with prior art, the present invention has following beneficial effect: by arranging cavity 4a, the working medium inlet 4b communicated with cavity 4a and perforate 4c, piston 5, the fixed plate 6 affixed with piston 5 and elastomer 7 on inner ring 4.Make fixed plate 6 hold tightly or loosen axle by the pressure of alter working medium, thus complete the fixing of bearing and dismounting easily.Simultaneously after adopting the working medium that specific heat is higher, the heat produced when can also absorb more bearing working, thus bearing is better cooled.
Below to invention has been detailed description, but the present invention is not limited to embodiment described herein.It will be appreciated by those skilled in the art that in the case without departing from the scope of the present invention, other changes and distortion can be made.Such as, described elastomer 7 can also be block rubber, and protection scope of the present invention is defined by the following claims.
