Abstract
The utility model belongs to the technical field of thrust bearings, in particular to an angular contact thrust bearing, comprising an inner ring, an outer ring, roll balls and a holding frame. The roll balls are limited by the holding frame to make movement on the raceways of the inner ring and the outer ring; the outer diameter of the inner ring is smaller than that of the other ring, and the inner diameter of the inner ring is smaller than that of the outer ring; the holding frame has the same outer diameter as the outer ring; the holding frame has the same inner diameter as the inner ring; and the raceways of the inner ring and outer ring have a certain contact angle. Compared with the conventional thrust bearing, the angular contact thrust bearing not only can bear axial load, but also can bear radial load, has simple production technology and wide applied range, and is suitably popularized in and applied to the machinery fields.
Description
Technical field:
The utility model belongs to the technical field of thrust-bearing, refers 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 utility model provides a kind of bearing axially and the angular contact thrust bearing of radial force.
The utility model 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 utility model is:
1, the utility model is compared 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, the utility model precision height, good rigidly, the rotating speed height, mounting or dismounting are convenient, and use occasion is wide;
3, the external diameter of the utility model 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 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 utility model;
Fig. 2 is the generalized section of outer ring of the present utility model;
Fig. 3 is the generalized section of retainer of the present utility model;
Fig. 4 is the generalized section of inner ring of the present utility model;
Fig. 5 is the generalized section of retainer cross section of the present utility model.
Embodiment:
With specific embodiment the utility model 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 utility model is 75 degree.
The utility model is compared 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 only is one of preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; so: all equivalences of doing according to shape of the present utility model, structure, principle change, and all should be covered by within the protection domain of the present utility model.
Claims (3)
