Description

Bidirectional bearing capable of simultaneously bearing radial and axial forces

The technical field is as follows:

the utility model relates to a can bear radial and axial force's two-way bearing simultaneously.

Background art:

it is known that the main function of a bearing is to support the rotating body of a machine and to reduce the friction coefficient during its movement. At present, some bearings on the market are radial bearings, some bearings are thrust bearings, the radial bearings bear pure radial loads, the thrust bearings bear pure axial loads, the bearings can only bear loads in a certain direction, and at present, no bidirectional bearing capable of bearing both radial forces and axial forces exists, so that the structures of a plurality of mechanical devices become complicated.

The utility model has the following contents:

the present invention is directed to overcome the above-mentioned disadvantages of the prior art, and to provide a bidirectional bearing capable of simultaneously bearing radial and axial forces.

The utility model discloses a utility model purpose can realize through following technical scheme: the utility model provides a can bear two-way bearing of radial and axial force simultaneously, including the inner circle, outer lane and first ball, the inner circle cover is in the outer lane, first ball is provided with many, first ball sets up between inner circle and outer lane, the shaping has the annular ladder structure of evagination on the outer periphery of outer lane, be provided with supplementary clamping ring in annular ladder department, along circumference interval arrangement have many second balls between the ladder plane of supplementary clamping ring and annular ladder, along circumference interval arrangement have many third balls between supplementary clamping ring and the ladder facade.

After adopting this technical scheme, compare with prior art, this technical scheme has following advantage: the bearing has the functions of both radial bearing and thrust bearing, and has raised use adaptability and simplified structure.

Description of the drawings:

FIG. 1 is a sectional structural view of the two-way bearing of the present invention;

fig. 2 is a sectional exploded view of the bidirectional bearing of the present invention.

The specific implementation mode is as follows:

the present technology is further described below with reference to the accompanying drawings.

The bidirectional bearing capable of bearing radial and axial forces simultaneously comprises an inner ring 1, an outer ring 2 and first balls 3, wherein the inner ring 1 is sleeved in the outer ring 2, the first balls 3 are provided with a plurality of balls, the first balls 3 are evenly distributed between the inner ring 1 and the outer ring 2 at intervals along the circumference, a first retainer 4 is further arranged between the inner ring 1 and the outer ring 2, the first balls 3 are arranged on the first retainer 4, an outward-protruding annular step structure is formed on the outer circumferential surface of the outer ring 2, an auxiliary clamping ring 6 is arranged at the annular step 5, a plurality of second balls 7 are evenly distributed between the auxiliary clamping ring 6 and a step plane 51 of the annular step 5 at intervals along the circumference, a plurality of third balls 8 are evenly distributed between the auxiliary clamping ring 6 and the step plane 52 at intervals along the circumference, a second retainer 9 is arranged between the auxiliary clamping ring 6 and the step plane 51, a third retainer 10 is arranged between the auxiliary clamping ring 6 and the step plane 52, the second balls 7 are mounted on a second cage 9 and the third balls 8 are mounted on a third cage 10. All the surfaces which are contacted and matched with the first ball 3, the second ball 7 and the third ball 8 are formed with concave rings 11, and the first ball 3, the second ball 7 and the third ball 8 are matched and rolled with the concave rings 11.

The first ball 3 and the third ball 8 of the present technology act to carry radial loads, while the second ball 7 acts to carry axial loads, so that the present bearing can carry both radial and axial loads.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention in any way. The invention is not limited to the embodiments described herein, but is capable of other embodiments with obvious modifications and variations, including those shown in the drawings and described herein. Therefore, the equivalent changes made according to the shape, structure and principle of the present invention should be covered in the protection scope of the present invention.

Claims (1)

1.
