Abstract
The invention discloses bearings easy for installation.By in inner ring（4）Upper setting cavity（4a）With cavity（4a）The working media inlet communicated（4b）And trepanning（4c）And piston（5）With with piston（5）Affixed fixinig plate（6）.By the pressure fixinig plate for changing fluid working medium（6）It holds tightly or loosens axis, so as to be conveniently accomplished the fixation of bearing and dismounting.Simultaneously after the working media higher using specific heat, moreover it is possible to the heat generated during more bearing workings is absorbed, so as to which bearing be made preferably to be cooled down.
Description
Technical field
The present invention relates to field of bearings, more particularly to bearing easy for installation.
Background technology
Rolling bearing has application more as standard component in the bearing of various rotatable parts.But during 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
Bearing heating is made into its inner ring swell and then is inserted on axis again.The handling of bearing are all very inconvenient in a word.
Invention content
In order to which drawbacks described above and the insufficient present invention is overcome to provide following technical scheme：Bearing easy for installation, the bearing
Including outer ring, rolling element, retainer, inner ring, the inner ring is internally provided with a cavity, and the inner ring end face is equipped with and the chamber
The working media inlet that body is connected, the working media inlet can be closed, closest to the side of fixing axle on the inner ring
Wall is equipped with several trepannings, and the trepanning is connected with the cavity, and matched piston, the work are equipped in the trepanning
Plug is fixedly connected with a fixinig plate.
During installation, first by bearing holder (housing, cover) on axis so that be not provided on bearing inner race the top surface of working media inlet with
Shaft shoulder face overlaps, and the working media of high pressure is then injected into cavity by the working media inlet, due to working media
Pressure by piston eject so as to which all fixinig plates be made to hold axis tightly simultaneously so that bearing is fixed on axis, finally by working media
Inlet is closed.During dismounting, working media inlet is opened, the high-pressure working medium in cavity is extracted out so that cavity pressure
It is released, fixinig plate no longer holds axis tightly, so as to easily unload bearing.
Preferably, several boss prominent to the cavity are equipped with closest to the side wall of fixing axle on the inner ring,
The boss is equipped with the trepanning, and the trepanning runs through the boss and its side wall at place, and is communicated with the cavity.This
Sample setting is on the one hand so that the contact area between piston and trepanning increases so that better tightness；Piston cunning is also increased simultaneously
Dynamic stroke, so that bearing can match more diameters of axle.
Preferably, shape of the fixinig plate on the radial section of bearing is sector.Setting is so that fixinig plate in this way
It can be preferably bonded with fixing axle, so that bearing is more securely attached so as to increase contact area.
Preferably, the working media inlet does not protrude the end face of the inner ring where it.Setting avoids in this way
The working media inlet is interfered with other parts.
Compared with prior art, the invention has the advantages that：By setting cavity on inner ring, being communicated with cavity
Working media inlet and trepanning and piston and the fixinig plate affixed with piston.Made by the pressure for changing fluid working medium
It obtains fixinig plate and holds or loosen axis tightly, so as to be conveniently accomplished the fixation of bearing and dismounting, while using the higher work of specific heat
After medium, moreover it is possible to the heat generated during more bearing workings is absorbed, so as to which bearing be made preferably to 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 A portions enlarged drawing.
Specific embodiment
Below in conjunction with the accompanying drawings, it elaborates to the specific embodiment of the present invention.Bearing easy for installation, the bearing
Including outer ring 1, rolling element 2, retainer 3, inner ring 4, the inner ring 4 is internally provided with a cavity 4a, and 4 end face of inner ring is equipped with
The working media inlet 4b being connected with the cavity 4a, the working media inlet 4b can be closed, and the work is situated between
Matter inlet 4b does not protrude the end face of the inner ring 4 where it, closest to the side wall upper edge even circumferential of fixing axle on the inner ring 4
Setting run through there are six trepanning 4c, the trepanning 4c is equipped on the boss 4d, each boss 4d prominent to the cavity 4a
The boss 4d and its side wall at place, and communicated with the cavity 4a, it is equipped with matched work in each trepanning 4c
Plug 5, each piston 5 are fixedly connected with a fixinig plate 6, and shape of each fixinig plate 6 on the radial section of bearing is sector.
During installation, first by bearing holder (housing, cover) on axis so that the top surface of working media inlet 4b is not provided on bearing inner race 4
It is overlapped with shaft shoulder face, the hydraulic oil of high pressure is then injected into cavity 4a by the working media inlet 4b, due to hydraulic pressure
The pressure of oil ejects piston 5 six fixinig plates 6 is made to hold axis tightly so that bearing is fixed on axis, finally by working media
Inlet 4b is closed.During dismounting, working media inlet 4b is opened, the high pressure liquid pressure oil in cavity 4a is extracted out so that intracavitary
Pressure is released, and fixinig plate 6 no longer holds axis tightly, so as to easily unload bearing.
Compared with prior art, the invention has the advantages that：By setting cavity 4a and cavity on inner ring 4
The working media inlet 4b and trepanning 4c and piston 5 and the fixinig plate 6 affixed with piston 5 that 4a is communicated.By changing fluid work
Make the pressure of medium so that axis is held or loosened to fixinig plate 6 tightly, so as to be conveniently accomplished the fixation of bearing and dismounting.It is using simultaneously
After the higher working media of specific heat, moreover it is possible to the heat generated during more bearing workings is absorbed, so as to which bearing be made to obtain 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.This hair
