Description
Technical field
The present invention relates to field of bearings, more particularly to a kind of bearing being easily installed.
Background technology
Rolling bearing has application more as standard component in the bearing of various rotatable parts.But when current bearing installation by
It is interference fit in bearing inner race and axis, is to be installed by way of tapping or being pressed into forcing press under normal circumstances, also has
Its inner ring swell is set then to be inserted on axis again bearing heating.The handling of bearing are all very inconvenient in a word.
Invention content
In order to overcome drawbacks described above and the insufficient present invention to provide following technical scheme:A kind of bearing being easily installed, it is described
Bearing includes outer ring, rolling element, retainer, inner ring, and the inner ring is internally provided with a cavity, and the inner ring end face is equipped with and institute
The working media inlet that cavity is connected is stated, the working media inlet can be closed, and the working media inlet is not
The end face of the prominent inner ring where it is equipped with closest to the side wall of fixing axle on inner ring several prominent to the cavity
The boss gone out, the boss are equipped with trepanning, the trepanning through the boss and its place side wall, and with the cavity phase
It is logical, it is equipped with matched piston in the trepanning, fixes a piston rod on the piston, an elastomer sleeve is located at the work
On stopper rod, one end of the elastomer is contacted with the end face for connecting piston rod on the piston, and the other end is withstood on the inner ring,
The piston is fixedly connected with a fixinig plate by piston rod, and shape of the fixinig plate on the radial section of bearing is sector.
When installation, first by bearing holder (housing, cover) on axis, since the effect of elastomer makes piston receive in the opening,
Bearing can be very easily sleeved on axis so that the top surface that working media inlet is not arranged on bearing inner race is overlapped with shaft shoulder face.
Then the working media for injecting high pressure into cavity 4a by the working media inlet, since the pressure of working media will live
Plug ejection, elastomer are compressed, and fixinig plate holds axis tightly so that bearing is fixed on axis, finally closes working media inlet.
When dismounting, working media inlet is opened, the high-pressure working medium in cavity is extracted out and so that cavity pressure is released, piston
It is withdrawn in trepanning under the action of elastomer, drives fixinig plate to loosen axis, so as to easily unload bearing.
Preferably, be provided in the trepanning with its sprue that matches, the sprue closes the trepanning just, described
Sprue is equipped with through-hole, and the piston rod is pierced by from the through-hole is fixedly connected with the fixinig plate, one end of the elastomer
It is contacted with the end face for connecting piston rod on the piston, the other end is withstood on the sprue.Setting is so that piston and elasticity in this way
The assembly of body and inner ring is more convenient.
Preferably, the elastomer can be one of spring or rubber block.
Compared with prior art, the invention has the advantages that:By the way that cavity is arranged on inner ring, is communicated with cavity
Working media inlet and trepanning, piston, with piston affixed fixinig plate and elastomer.By changing fluid working medium
Pressure makes fixinig plate hold tightly or loosen axis, to be conveniently accomplished the fixation and dismounting of bearing.Simultaneously higher using specific heat
Working media after, moreover it is possible to the heat generated when more bearing workings is absorbed, to make bearing preferably be cooled down.
Description of the drawings
Fig. 1 is the front view when bearing in embodiment of the present invention is mounted on an axle.
Fig. 2 is the front view when bearing in embodiment of the present invention is not installed on axis.
Fig. 3 is to face full sectional view when the bearing in embodiment of the present invention is not installed on axis.
Fig. 4 is the portions A enlarged drawing.
Specific implementation mode
Below in conjunction with the accompanying drawings, it elaborates to the specific implementation mode of the present invention.A kind of bearing being easily installed, it is described
Bearing includes outer ring 1, rolling element 2, retainer 3, inner ring 4, and the inner ring 4 is internally provided with a cavity 4a, on 4 end face of the inner ring
Equipped with the working media inlet 4b being connected with the cavity 4a, the working media inlet 4b can be closed, and the work
Make the end face for the inner ring 4 that medium inlet 4b is not protruded where it, closest to setting on the side wall of fixing axle on the inner ring 4
There are six trepanning 4c, the trepanning 4c to cavity 4a boss 4d outstanding, are equipped on each boss 4d through described convex
Platform 4d and its side wall at place, and communicated with the cavity 4a, matched piston 5, institute are equipped in each trepanning 4c
State and be fixed with piston rod on piston 5, a spring 7 is sheathed on the piston rod, be also threaded in each trepanning 4c and its
Match sprue 4e, and the sprue 4e closes the trepanning 4c just, and the sprue 4e is equipped with through-hole, and the piston rod is from institute
It states to be pierced by through-hole and is fixedly connected with fixinig plate 6, shape of the fixinig plate 6 on the radial section of bearing is sector, the bullet
One end of spring 7 is contacted with the end face for connecting piston rod on the piston 5, and the other end is withstood on the sprue 4e.
When installation, first by bearing holder (housing, cover) on axis, since the effect of spring 7 makes piston 5 be received in the trepanning 4c, because
This bearing can be very easily sleeved on axis so that top surface and the shaft shoulder face of working media inlet 4b is not arranged on bearing inner race 4
It overlaps.Then the hydraulic oil for injecting high pressure into cavity 4a by the working media inlet 4b, due to the pressure of hydraulic oil
Piston 5 is ejected, spring 7 is compressed, and six fixinig plates 6 hold axis tightly so that bearing is fixed on axis, finally notes working media
Entrance 4b closings.When dismounting, working media inlet 4b is opened, the high pressure liquid pressure oil in cavity 4a is extracted out so that intracavitary pressure
Power is released, and piston 5 is withdrawn under the action of spring 7 in trepanning, drives fixinig plate 6 to loosen axis, so as to easily by axis
It holds and unloads.
Compared with prior art, the invention has the advantages that:By the way that cavity 4a and cavity are arranged on inner ring 4
Working media inlet 4b and trepanning 4c, piston 5 and the affixed fixinig plate 6 of piston 5 and the elastomer 7 that 4a is communicated.Pass through change
The pressure of fluid working medium makes fixinig plate 6 hold tightly or loosen axis, to be conveniently accomplished the fixation and dismounting of bearing.Simultaneously
After using the higher working media of specific heat, moreover it is possible to the heat generated when more bearing workings is absorbed, to make bearing obtain
It is preferably cooling.
Above to the present invention have been described in detail, but the invention is not limited in specific embodiment parties described herein
Formula.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 deformation can be made.For example,
The elastomer 7 can also be that rubber block, protection scope of the present invention are defined by the following claims.
