Description
Technical field
The present invention relates to field of bearings, more particularly to a kind of easy-to-mount bearing.
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
Its inner ring is made to swell and then be inserted on axis again bearing heating.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：A kind of easy-to-mount bearing, it is described
Bearing includes outer ring, rolling element, retainer, inner ring, and the inner ring includes lining ring, flexible cavity, working media inlet, described
The outer surface of lining ring is contacted with the rolling element, and the inner surface of the lining ring is fixedly connected with the outer surface of the flexible cavity,
The compliance cavity body end face is equipped with the working media inlet being connected with the flexible cavity, the working media inlet
It can close, be fixedly connected with several pieces of push plates on the inner surface of the flexibility cavity, the push plate connects 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.Then the working media of high pressure is injected into compliance cavity body by the working media inlet, due to work
The pressure of medium causes flexible cavity to expand, and pushes push plate, and push plate drives fixinig plate to hold axle journal tightly, finally notes working media again
Entrance is closed.During dismounting, working media inlet is opened, the high-pressure working medium in compliance cavity body is extracted out so that intracavitary pressure
Power is released, and flexible cavity is shunk, and drives push plate, push plate drives fixinig plate to loosen axle journal, so as to easily unload bearing
Under.
Preferably, the push plate is equipped with a connecting rod, the end of the connecting rod is equipped in bulb A, the bulb A
Portion is equipped with a spherically-shaped cavity, and the hole is equipped with opening on the lower face of the bulb A, and the fixinig plate, which is equipped with, to be protruded
Portion, the diameter that the top of the protruding portion is fixedly connected with spherical bulb a B, the bulb B are straight no more than the hole
Diameter, and the diameter of bulb B is more than the maximum distance of point-to-point transmission in the opening on the bulb A lower faces, the bulb B
In the embedded hole, the protruding portion is inserted into the opening on the bulb A lower faces, and can be freely movable.
Preferably, surface upper edge its outer contour being connect in the push plate with the flexible cavity be provided with it is arc-shaped
Chamfering.Setting is avoided since jagged or sharp edge easily staves flexible cavity on the edge of push plate upper surface in this way, so as to
Bearing is caused surprisingly to come off.
Preferably, shape of the fixinig plate on the radial section of bearing is sector, the working media inlet
Do not protrude the end face of the flexible cavity where it.So on the one hand setting enables fixinig plate preferably to be pasted with fixing axle
It closes, so that bearing is more securely attached so as to increase contact area, on the other hand setting avoids the working media note in this way
Entrance is interfered with other parts.
Compared with prior art, the present invention has the following advantages：By setting flexible cavity and the flexibility on inner ring
Working media inlet that cavity communicates, push plate, the fixinig plate being flexibly connected with push plate.By changing fluid work in compliance cavity body
Make the pressure of medium so that flexible cavity expansion or shrinkage drives fixinig plate to hold tightly or loosen so as to push push plate, then by push plate
Axis, so as to be conveniently accomplished the fixation of bearing and dismounting, the larger fluid of some specific heats of simultaneous selection can also as working media
A large amount of amount of heat for absorbing rolling element and generating, so that bearing can be cooled down preferably.

Specific embodiment
Below in conjunction with the accompanying drawings, it elaborates to the specific embodiment of the present invention.A kind of easy-to-mount bearing, it is described
Bearing includes outer ring 1, rolling element 2, retainer 3, inner ring 4.The inner ring 4 includes lining ring 4a, flexible cavity 4b, working media note
Entrance 4c, the outer surface of the lining ring 4a are contacted with the rolling element 2, the inner surface of the lining ring 4a and the flexible cavity 4b
Outer surface be bonded together, the flexibility cavity 4b end faces are equipped with the working media that is connected with the flexibility cavity 4b and note
Entrance 4c, the working media inlet 4c can be closed, and the working media inlet 4c do not protrude it is described soft where it
The end face of property cavity 4b.Be bonded with six pieces of push plates 5 on the inner surface of the flexibility cavity 4b, in the push plate 5 with the flexibility
Its outer contour of the surface upper edge of cavity 4b connections is provided with circular arc chamfering, and a connecting rod 5a is equipped in every piece of push plate 5,
The end of the connecting rod 5a is equipped with bulb A5b, and the bulb A5b is internally provided with a spherically-shaped cavity 5c, and the hole 5c exists
The lower face of the bulb A5b is equipped with opening.The fixinig plate 6 also is provided with six, and the every fixinig plate 6 is in bearing
Shape on radial section is sector, and protruding portion 6a is equipped on the every fixinig plate 6, and the top of the protruding portion 6a is equal
The diameter for being fixedly connected with spherical bulb a B6b, the bulb B6b is not more than the diameter of the hole 5c, and described expands
The diameter of portion B6b is more than the maximum distance of point-to-point transmission in the opening on the bulb A5b lower faces.The every fixinig plate 6
On bulb B6c be embedded in the hole 5c in every piece of push plate 5, the protruding portion 6a is inserted under the bulb A5b
In opening on end face, and can be freely movable.
During installation, first by bearing holder (housing, cover) on axis so that the end face of working media inlet 4c is not provided on bearing inner race 4
It is overlapped with shaft shoulder face.Then the hydraulic oil of high pressure is injected into flexible cavity 4b by the working media inlet 4c, due to
The pressure of hydraulic oil causes flexible cavity 4b to expand, and six pieces of push plates 5 is pushed to move simultaneously, and six fixinig plates 6 is driven to hold axle journal tightly,
So that bearing is fixed on axis, finally working media inlet 4c is closed.During dismounting, working media inlet 4c is opened,
High pressure liquid pressure oil in flexible cavity 4b is extracted out so that cavity pressure is released, flexible cavity 4b is shunk, and drives all push plates 5
Recycling, every piece of push plate 5 drives every fixinig plate 6 to loosen axle journal again, so as to easily unload bearing.
Compared with prior art, the present invention has the following advantages：By set on inner ring 4 flexible cavity 4b, with it is described
Working media inlet 4c that flexible cavity 4b is communicated, push plate 5, the fixinig plate 6 being flexibly connected with push plate 5.It is flexible by changing
The pressure of fluid working medium causes flexible cavity 4b expansion or shrinkage to be driven so as to push push plate 5, then by push plate 5 in cavity 4b
Axis is held or loosened to fixinig plate 6 tightly, so as to be conveniently accomplished the fixation of bearing and dismounting, the larger fluid of some specific heats of simultaneous selection
The amount of heat of rolling element generation can also be largely absorbed as working media, so that bearing can be cooled down preferably.
Above to the present invention have been described in detail, but the invention is not limited in specific embodiment parties described herein
