Abstract

The utility model discloses a novel combination formula bearing structure, including bearing body (1), bearing body (1) is including bearing inner race (2), holder (3), bearing inner race (4) and tapered roller (5), bearing body (1) is from interior bearing inner race (2) and bearing inner race (4) to having set gradually outward, be equipped with holder (3) between bearing inner race (2) and bearing inner race (4), be equipped with tapered roller (5) on holder (3), the bearing inner race is tapered roller bearing outer lane to be equipped with boss portion (6) in this bearing inner race outside. The utility model discloses a bearing inner race has changed original tapered roller bearing's outer lane structure, has increased boss portion on tapered roller bearing outer lane to the use position installation at equipment is adapted to, makes the existing plane thrust ball bearing's of this design bearing service function, also has tapered roller bearing's the characteristic that bears.

Description

Novel combined bearing structure

Technical Field

The utility model relates to a bearing technical field, concretely relates to novel combination formula bearing structure.

Background

The existing plane thrust ball bearing can only bear larger axial thrust, but the radial bearing capacity is limited, so that the existing plane thrust ball bearing cannot well meet the use requirement of equipment. The bearing is used on a vehicle steering column and bears large axial bearing force and large radial bearing force when a vehicle runs, so that the bearing is easy to damage. Therefore, it is highly desirable to develop a novel combined bearing structure by those skilled in the art.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the not enough of existence among the above-mentioned prior art, provide a novel combination formula bearing structure, the bearing inner race of this design has changed original tapered roller bearing's outer lane structure, has increased boss portion on tapered roller bearing outer lane to the adaptation is installed at the use position of equipment, makes the existing plane thrust ball bearing's of this design bearing service function, also has tapered roller bearing's the characteristic of bearing, has greatly improved radial bearing capacity.

In order to achieve the purpose of the utility model, the utility model provides a technical scheme as follows: the utility model provides a novel combined bearing structure, includes the bearing body, the bearing body includes bearing inner race, holder, bearing inner race and tapered rolling element, the bearing body has set gradually bearing inner race and bearing inner race from inside to outside, be equipped with the holder between bearing inner race and the bearing inner race, be equipped with tapered rolling element on the holder, the bearing inner race is tapered roller bearing outer lane to be provided with boss portion in this bearing inner race outside.

Preferably, the bearing further comprises a dust cover, and the dust cover is arranged on the bearing outer ring.

Preferably, the bearing inner ring, the bearing outer ring and the retainer are all made of bearing steel or stainless steel materials.

Preferably, the bearing outer ring raceway is a conical cambered surface.

Based on the technical scheme, compared with the prior art, the utility model have following technical advantage:

the utility model discloses a novel combined bearing structure, structural design is reasonable, long service life, the bearing inner race of this design has changed original tapered roller bearing's outer lane structure, increased boss portion on tapered roller bearing outer race to adapt to the use position installation at equipment, make this design bearing existing plane thrust ball bearing's service function, also have tapered roller bearing's load-bearing characteristic, utilize tapered rolling element can bear great axial bearing capacity and radial bearing capacity, make the advantage of two kinds of bearings collect on this design bearing, solved the problem that the plane thrust ball bearing that original vehicle steering column used can only bear great axial bearing capacity but can not bear radial bearing capacity; the raceway of the outer ring of the bearing is designed into a conical cambered surface, so that the joint action of bearing axial load and radial load at the same time is ensured.

Drawings

Fig. 1 is a schematic sectional view of the combined bearing structure of the present invention.

In the figure: 1. the bearing comprises a bearing body, 2. a bearing inner ring, 3. a retainer, 4. a bearing outer ring, 5. a conical rolling body, 6. a boss part and 7. a dust cover.

Detailed Description

The invention is further explained below with reference to the drawings and examples.

As shown in fig. 1, a novel combined bearing structure includes a bearing body 1, the bearing body 1 includes a bearing inner ring 2, a retainer 3, a bearing outer ring 4 and a tapered rolling element 5, the bearing body 1 has the bearing inner ring 2 and the bearing outer ring 4 from inside to outside in proper order, the retainer 3 is arranged between the bearing inner ring 2 and the bearing outer ring 4, the tapered rolling element 5 is arranged on the retainer 3, the bearing outer ring 4 is a tapered roller bearing outer ring, and a boss portion 6 is arranged outside the bearing outer ring 4.

The bearing outer ring bearing further comprises a dust cover 7, and the dust cover 7 is arranged on the bearing outer ring 4. The bearing inner ring 2, the bearing outer ring 4 and the retainer 3 are all made of bearing steel or stainless steel materials. The raceway of the bearing outer ring 4 is a conical cambered surface and can bear the combined action of axial load and radial load.

The foregoing is illustrative and explanatory of the invention and is not intended to limit the advantages attainable thereby, and it is within the scope of the present application to practice the invention with simple modifications to the structure and/or one or more of the advantages achieved in some embodiments.
