Description
[technical field]
The utility model relates to technical field of bearings, relates in particular to a kind of ball bearing, is specifically related to a kind of fulcrum ball bearing that moves about.
[background technique]
Known, in the main shaft of lathe, require high temperature resistant, rotating speed height and the high axle of precision adopt one end to fix more, the support combinations form of moving about in one end, and this spring bearing requires high limit rotating speed, to bearing capacity, require lower, the end that wherein moves about does not carry out axially locating to bearing, in conventional support adopts, the separable roller bearing in outer ring, it can meet the play of axle, but owing to being subject to the impact of roller bearing limit speed, be not suitable for the occasion that rotating speed is higher, for above situation, traditional roller bearings can not meet this requirement.
[summary of the invention]
In order to overcome the deficiency of above-mentioned technology, the utility model provides a kind of fulcrum ball bearing that moves about, the utility model by arranging low density, the high-strength engineering plastic retainer with retainer function between bearing outer ring and bearing inner race, can realize bearing outer ring separated with bearing inner race after ceramic ball from bearing, be not scattered, further, by raceway in straight line type is set on the outer edge surface of bearing inner race, can realize the play of the relative bearing outer ring of bearing inner race etc., its limit speed is several times of unidimensional roller bearing.
For realizing goal of the invention as above, the utility model adopts technological scheme as described below:
A kind of fulcrum ball bearing that moves about, comprise bearing outer ring, ceramic ball, retainer and bearing inner race, on the outer edge surface of described bearing inner race, be provided with raceway in straight line type, outside at bearing inner race is provided with bearing outer ring, described bearing inner race and bearing outer ring are to arrange with one heart, between bearing inner race and bearing outer ring, be provided with retainer, in the pocket hole on described retainer, be respectively equipped with ceramic ball and form the described fulcrum ball bearing that moves about.
The described fulcrum ball bearing that moves about, described retainer is provided with a plurality of pockets hole.
The described fulcrum ball bearing that moves about, on described retainer, the bottom in each pocket hole is provided with locking ring.
The described fulcrum ball bearing that moves about, described retainer is low density, high-intensity engineering plastics cage.
The described fulcrum ball bearing that moves about, the inner edge surface of described bearing outer ring is provided with the outer raceway of arc.
The described fulcrum ball bearing that moves about, described ceramic ball is silicon nitride ceramic ball.
Adopt technological scheme as above, the utlity model has superiority as described below:
A kind of fulcrum ball bearing that moves about described in the utility model, the utility model by arranging low density, the high-strength engineering plastic retainer with retainer function between bearing outer ring and bearing inner race, can realize bearing outer ring separated with bearing inner race after ceramic ball from bearing, be not scattered, further, by raceway in straight line type is set on the outer edge surface of bearing inner race, can realize the play of the relative bearing outer ring of bearing inner race, the utility model can improve the limit speed of bearing, and the light duty that is particularly suitable for rotating speed to have higher requirements is used.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model;
In the drawings: 1, bearing outer ring; 2, ceramic ball; 3, retainer; 4, bearing inner race; 5, outer raceway; 6, interior raceway; 7, pocket hole.
[embodiment]
By the following examples, can explain in more detail the utility model, the utility model is not limited to the following examples;
A kind of fulcrum ball bearing that moves about described in 1 by reference to the accompanying drawings, comprise bearing outer ring 1, ceramic ball 2, retainer 3 and bearing inner race 4, on the outer edge surface of described bearing inner race 4, be provided with raceway 6 in straight line type, in the outside of bearing inner race 4, be provided with bearing outer ring 1, the inner edge surface of described bearing outer ring 1 is provided with the outer raceway 5 of arc, wherein bearing inner race 4 and bearing outer ring 1 all adopt high-speed bearing Steel material, described bearing inner race 4 and bearing outer ring 1 are to arrange with one heart, between bearing inner race 4 and bearing outer ring 1, be provided with retainer 3, described retainer 3 is low density, high-intensity engineering plastics cage, described retainer 3 is provided with a plurality of for the fixing pocket hole 7 of ceramic ball 2, now in order to prevent that ceramic ball 2 from deviating from pocket hole 7, on described retainer 3, the bottom in each pocket hole 7 is provided with locking ring, or lock point is set on retainer 3 internal diameters pins a ceramic ball 2, guarantee that ceramic ball 2 rear ceramic ball 2 separated with bearing inner race 4 do not drop out in the pocket hole 7 from retainer 3, in pocket hole 7 on described retainer 3, be respectively equipped with ceramic ball 2, described ceramic ball 2 is silicon nitride ceramic ball, and then the high speed performance of raising bearing.
By enforcement of the present utility model, the utlity model has following advantage:
1, the utility model is compared with roller bearing, has very high limit speed, is about 2 times of left and right of unidimensional roller bearing;
2, can realize axle and carry axial freely moving about;
3, because the inside and outside circle of bearing can be separated, be convenient to bearing and pack main frame into;
4, the friction torque of bearing is little;
5, bearing inner race 4 is not with rib, and the space of bearing is more open, and radiating condition is good, thereby can improve high speed running performance of bearing etc.
The utility model does not describe part in detail for prior art.
The embodiment who selects in this article for open the purpose of this utility model, currently thinks suitablely, still, will be appreciated that, the utility model is intended to comprise that all belong to all changes and the improvement of the embodiment in this design and invention scope.
