Abstract
The utility model relates to a bearing which comprises a bearing outer ring and a bearing inner ring which is arranged inside the bearing outer ring, wherein, a rotatable first steel ball is arranged between the bearing outer ring and the bearing inner ring and located between the bearing outer ring and the bearing inner ring through a first carriage; a circular recess is arranged on the side surface of the bearing inner ring; a second steel ball is arranged inside the circular recess, located in the circular recess through a second carriage and protrudes out of the side surface of the bearing inner ring. The utility model can simultaneously realize movement of the bearing along the direction which is perpendicular to a center line of the bearing and rotation of the bearing around the center line, and has the advantages of wide range of application and convenient use.
Description
Technical field
The utility model relates to a kind of bearing.
Background technique
Existing bearing, generally comprise bearing outer ring and be positioned at the bearing inner race of bearing outer ring, be provided with rotating steel ball between bearing outer ring and the bearing inner race, steel ball is positioned between bearing outer ring and the bearing inner race by supporting frame, described steel ball can rotate, thereby realizes the relative movement of bearing outer ring and bearing inner race.Then,, in the time of on being fixed to axle, can only realize a kind of motion mode, promptly can only rotate around bearing axis no matter this kind bearing is standard piece or combination bearing; And the application of bearing now more and more widely, and it is more single to cause existing bearing to use like this, and causes inconvenience in practical application.
Summary of the invention
The purpose of this utility model is to provide a kind of bearing, and it is widely used, and is easy to use.
To achieve these goals, the utility model provides a kind of bearing, the bearing inner race that it comprises bearing outer ring and is positioned at bearing outer ring, be provided with rotating first steel ball between described bearing outer ring and the bearing inner race, described first steel ball is positioned between bearing outer ring and the bearing inner race by first supporting frame, described bearing inner race side surface is provided with circular trough, be provided with second steel ball in this circular trough, described second steel ball is positioned to circular trough by second supporting frame, and second steel ball protrudes in the bearing inner race side surface.
As improvement, described bearing inner race two side surfaces are provided with circular trough, are provided with second steel ball in this two circular trough, and described second steel ball is fixed to circular trough by supporting frame.
As further improvement, described bearing inner race is provided with groove, and correspondingly, support frame as described above is provided with the fixed block that can match with groove.
As further improvement, described groove is connected by welding manner with fixed block.
As further improvement, described groove is connected by the interference mode with fixed block.
Compared with prior art, the utility model bearing owing to be provided with steel ball at the bearing side surface, can realize simultaneously bearing along the direction vertical with bearing axis move with and around the rotation of center line, it is widely used, easy to use.
Description of drawings
Fig. 1 is the plan view of the utility model bearing;
Fig. 2 is the sectional view of A-A direction shown in Figure 1;
Fig. 2 is the utility model bearing second embodiment's a plan view.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Shown in seeing figures.1.and.2, the utility model bearing, the bearing inner race 2 that it comprises bearing outer ring 1 and is positioned at bearing outer ring 1, be provided with rotating first steel ball 3 between described bearing outer ring 1 and the bearing inner race 2, first steel ball 3 is positioned between bearing outer ring 1 and the bearing inner race 2 by first supporting frame 5, by the rotation of first steel ball 3, can drive bearing outer ring 1 and rotate, thereby realize that this bearing is around its center line rotation relative to bearing inner race 2.
Also be provided with circular trough 20 (certainly at described bearing inner race 2 two side surfaces, also can only be provided with circular trough) at a side surface, be provided with second steel ball 6 in this circular trough 20, described second steel ball 6 is positioned in the circular trough 20 by second supporting frame 7, on described bearing inner race 2, be provided with groove 21, correspondingly, second supporting frame 7 is provided with the fixed block 4 that can match with groove 21, and groove 21 and fixed block 4 are connected by welding manner.Certainly, also can connect by the mode of interference fit.And described second steel ball 6 protrudes in bearing inner race 2 side surfaces, realizes that it is around the vertical direction motion of bearing axis so that contact other surface.
Please refer to shown in Figure 3ly, be second embodiment of the utility model bearing, it is with the foregoing description difference: described second supporting frame 7 is not connected each other, and described circular trough 20 is not groove, but independent.
Compared with prior art, the utility model bearing is owing to be provided with steel at the bearing side surface Ball, can realize simultaneously bearing along the direction vertical with bearing axis move with and around in The rotation of heart line is widely used it, and is easy to use.
