Description
Technical field
The utility model is related to technical field of bearings, specially a kind of three rotatable pivoting supports of lasso double back.
Background technology
Pivoting support is the nearly 40 years novel mechanical parts worldwide gradually risen, it has Internal and external cycle, rolling
The compositions such as kinetoplast, pivoting support bearing generally carry mounting hole, internal gear or external gear, oilhole, also by internal gear and
The sealing device that clearance seal between external gear gets up, sealing device are two, are separately positioned on inner ring gear and outer ring tooth
On wheel, thus host design structure can be made compact, guiding is easy, safeguards and is easy, still, in the actual work, it has been found that
Existing slewing bearing is double lasso swingings, and outer shroud or inner ring are fixed on a certain position in use
When, although positive and negative rotation may be implemented, positive and negative rotation can not synchronize progress, so can only meet making for a part of user
With demand, for this purpose, we have proposed a kind of three rotatable pivoting supports of lasso double back.
Utility model content
The purpose of this utility model is to provide a kind of three rotatable pivoting supports of lasso double back, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the utility model provides the following technical solutions：A kind of three rotatable pivoting supports of lasso double back,
Including supporting inner ring, the bearing inner ring socket is provided with sandwich ring, and the bearing inner ring and sandwich ring are lived by the first steel ball
Dynamic connection, and bearing endocyclic outer wall and sandwich ring inner wall are both provided with the limiting slot to match with the first steel ball, the sandwich ring
Outer wall socket is provided with bearing outer shroud, and the sandwich ring and bearing outer shroud are flexibly connected by the second steel ball, and sandwich ring outer wall
It is both provided with the matched auxiliary stopper slot of the second steel ball with bearing outer shroud inner wall, the sandwich ring front end face is evenly arranged with four
Fixed block is organized, is symmetrically arranged with two groups of mounting holes on the fixed block, and sandwich ring front end face is provided with and is matched with mounting hole
Mounting hole.
Preferably, first steel ball and the second steel ball by interference fit be respectively arranged in bearing inner ring and sandwich ring and
Between sandwich ring and bearing outer shroud, and supports front/rear end between inner ring and sandwich ring and sandwich ring and bearing outer shroud and be both provided with
Sealing ring.
Compared with prior art, the utility model has the beneficial effects that：
1, pivoting support can be fixed by the fixed block on sandwich ring, passes through the mutual cooperation of mounting hole and fixing bolt
It is easily installed dismounting, can determine whether to install according to use demand；
2, by the mutual cooperation of the first steel ball and the second steel ball, bearing inner ring and bearing outer shroud positive and negative rotation can be made same
Step carries out, and more satisfies the use demand.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
In figure：1 bearing inner ring, 2 sandwich rings, 3 first steel balls, 4 bearing outer shrouds, 5 second steel balls, 6 fixed blocks, 7 mounting holes.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Referring to Fig. 1, the utility model provides a kind of technical solution：A kind of three rotatable pivoting supports of lasso double back, including
Inner ring 1 is supported, the bearing socket of inner ring 1 is provided with sandwich ring 2, supports inner ring 1 and sandwich ring 2 is flexibly connected by the first steel ball 3,
And bearing 1 outer wall of inner ring and 2 inner wall of sandwich ring are both provided with the limiting slot to match with the first steel ball 3, the socket of 2 outer wall of sandwich ring
It is provided with bearing outer shroud 4, sandwich ring 2 and bearing outer shroud 4 are flexibly connected by the second steel ball 5, and 2 outer wall of sandwich ring and bearing are outer
4 inner wall of ring is both provided with 5 matched auxiliary stopper slot of the second steel ball, and 2 front end face of sandwich ring is evenly arranged with four groups of fixed blocks
6, two groups of mounting holes 7 are symmetrically arranged on fixed block 6, and 2 front end face of sandwich ring is provided with and 7 matched installation of mounting hole
Hole.
Wherein, the first steel ball 3 and the second steel ball 5 are respectively arranged in bearing inner ring 1 and sandwich ring 2 and folder by interference fit
Between thimble 2 and bearing outer shroud 4, and supports front/rear end between inner ring 1 and sandwich ring 2 and sandwich ring 2 and bearing outer shroud 4 and be all provided with
It is equipped with sealing ring, sealing ring, which can prevent the first steel ball 3 and the second steel ball 5 from falling off, causes pivoting support that can not use, sealing ring
It is fixedly mounted by glass cement.
Operation principle：It, can be according to whether pivoting support is fixed, to pass through when needing to use pivoting support
