Abstract
The invention belongs to the thrust bearing technology field, more particularly relates to an angular contact thrust bearing; the angular contact thrust bearing consists of an inner ring, an outer ring, a ball bearing, and a retainer; the ball bearing is restricted by the retainer and moves on the raceways of the inner ring and the outer ring; the angular contact thrust bearing is characterized in that: the outer diameter of the inner ring is smaller than that of the outer ring; the inner diameter of the inner ring is smaller than that of the outer ring; the outer diameter of the retainer is the same as that of the outer ring; the inner diameter of the retainer is the same as that of the inner ring; and the raceways of the inner ring and the outer ring have a certain touching angle. Compared with the conventional thrust ball bearing, the angular contact thrust bearing not only can bear axial load, but also can bear radial load, has simple production technology and wide using occasions, and is suitable to popularization and application in various machinery fields.
Description
Technical field:
The invention belongs to the technical field of thrust-bearing, refer in particular to a kind of angular contact thrust bearing.
Background technique:
The function of bearing is supporting axle and parts on shaft, and keeps the running accuracy of axis, also is used for reducing the friction and wear between rotatingshaft and the supporting simultaneously.Common thrust-bearing if do not note, may be adorned instead when mounted, make the mistake, and such thrust-bearing is to be used for bearing specially the special bearing of axial force, and bear the bearing of the power of axial direction exactly, use occasion is narrower.
Summary of the invention:
The purpose of this invention is to provide a kind of bearing axially and the angular contact thrust bearing of radial force.
The present invention is achieved in that a kind of angular contact thrust bearing, form by inner ring, outer ring, ball and retainer, ball is subjected to move on the raceway that is limited in inner ring and outer ring of retainer, retainer is arranged between inner ring, the outer ring, it is characterized in that: the external diameter of inner ring is less than the external diameter of outer ring, and the internal diameter of inner ring is less than the internal diameter of outer ring, and the external diameter of retainer is identical with the external diameter of outer ring, the internal diameter of retainer is identical with the internal diameter of inner ring, and the raceway of inner ring and outer ring has certain wrapping angle.
Above-mentioned wrapping angle is 65～85 degree.
Above-mentioned wrapping angle is 75 degree.
The outstanding compared to existing technology advantage of the present invention is:
1, the present invention compares with the thrust ball bearing of routine, and the angle contacting thrust ball bearing not only can bear axial load, can also bear radial load;
2, precision height of the present invention, good rigidly, the rotating speed height, mounting or dismounting are convenient, and use occasion is wide;
3, the external diameter of inner ring of the present invention is less than the external diameter of outer ring, and the internal diameter of inner ring is less than the internal diameter of outer ring, and the front and back order is difficult for instead during installation, also than being easier to the location.
Description of drawings:
Fig. 1 is a generalized section of the present invention;
Fig. 2 is the generalized section of outer ring of the present invention;
Fig. 3 is the generalized section of retainer of the present invention;
Fig. 4 is the generalized section of inner ring of the present invention;
Fig. 5 is the generalized section of retainer cross section of the present invention.
Embodiment:
With specific embodiment the present invention is further described below, referring to Fig. 1-5:
A kind of angular contact thrust bearing, form by inner ring 4, outer ring 1, ball 3 and retainer 2, ball 3 is subjected to move on the raceway that is limited in inner ring 4 and outer ring 1 of retainer 2, retainer 2 is arranged between inner ring 4, the outer ring 1, it is characterized in that: the external diameter of inner ring 4 is less than the external diameter of outer ring 1, and the internal diameter of inner ring 4 is less than the internal diameter of outer ring 1, and the external diameter of retainer 2 is identical with the external diameter of outer ring 1, the internal diameter of retainer 2 is identical with the internal diameter of inner ring 4, and inner ring 4 has certain wrapping angle A with the raceway of outer ring 1.
Above-mentioned wrapping angle A can choose in 65～85 degree, and wrapping angle A of the present invention is 75 degree.
The present invention compares with the thrust ball bearing of routine, and the angle contacting thrust ball bearing not only can bear axial load, can also bear radial load; It is convenient to install, locate; Production technology is simple, and use occasion is wide, is adapted at each mechanical field and applies.
The foregoing description is one of preferred embodiment of the present invention only, is not to limit practical range of the present invention with this, so: all equivalences of doing according to shape of the present invention, structure, principle change, and all should be covered by within protection scope of the present invention.
Claims (3)
