Abstract
The utility model discloses an automobile hub bearing. The automobile hub bearing comprises an outer ring, an inner ring and a plurality of conical rollers, wherein the conical rollers are arranged between the outer ring and the inner ring in a rolling manner, the contact surfaces of the outer ring and the conical rollers are outer ring arc surfaces which protrude outwards, the contact surfaces between the inner ring and the conical rollers are inner ring arc surfaces which protrude outwards, and circumferential surfaces of the conical rollers are roller arc surfaces which protrude outwards. In the automobile hub bearing, as the circumferential surfaces of the conical rollers arranged to be the roller arc surfaces which protrude outwards, and the roller arc surfaces are respectively matched with the outer ring arc surfaces and the inner ring arc surfaces, larger radiuses of the outer ring arc surfaces and the inner ring arc surfaces can be realized, smaller curvature can also be realized, so that the bearing can bear a larger radial load, and axes of the inner ring and the outer ring can be ensured to have a certain angle of deflection.
Description
Technical field
The utility model relates to a kind of bearing, relates to a kind of tapered roller bearing that is used for automotive hub specifically, belongs to machine industry.
Background technique
Because automobile hub bearing is realizing that inside and outside circle in relative rotation under the prerequisite, also need allow the axis of inside and outside circle a certain amount of relative drift angle, existing automobile hub bearing to occur; Comprise that mainly inner ring, outer ring and rolling are connected the ball between the inside and outside circle; Ball is rotatably connected on the support, but adopts the automobile hub bearing of ball as roller, and it is radial and axial stressed less; Existing improved procedure is to adopt tapered roller as the automobile hub bearing roller; For a certain amount of relative drift angle can appear in the axis that guarantees inside and outside circle, need do camber at the surface of contact of inside and outside circle and tapered roller, the height of its arc has certain requirement; Cause the radius of arc of surface of contact of inside and outside circle and tapered roller less, curvature is bigger, the cambered surface that curvature is bigger has been placed restrictions on the radial force of bearing.
The model utility content
For overcoming above-mentioned defective, the utility model aims to provide and can bear bigger axial and radial force, can guarantee that again the automobile hub bearing of a certain amount of relative drift angle can appear in the axis of inside and outside circle simultaneously.
For achieving the above object; The technological scheme that the utility model adopts is: a kind of automobile hub bearing; Comprise that outer ring, inner ring and several rollings are connected the tapered roller between outer ring and the inner ring; The surface of contact of said outer ring and tapered roller is to the outer ring of outer lug cambered surface, and the surface of contact of said inner ring and tapered roller is the inner ring cambered surface to outer lug, and the circumferential surface of said tapered roller is the roller cambered surface to outer lug.
Adopted the utility model automobile hub bearing; Be roller cambered surface owing to being made as the circumferential surface of tapered roller to outer lug; Through the roller cambered surface respectively with the cooperating of outer ring cambered surface and inner ring cambered surface, the radius of outer ring cambered surface and inner ring cambered surface can be done more, its curvature can be littler; Thereby make bearing can bear bigger radial load, can guarantee that again a certain amount of relative drift angle can appear in the axis of inside and outside circle simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1-outer ring, 2-inner ring, 3-tapered roller, 4-outer ring cambered surface, 5-inner ring cambered surface, 6-roller cambered surface.
Embodiment
As shown in Figure 1; The utility model discloses a kind of automobile hub bearing, comprise that outer ring 1, inner ring 2 and several rollings are connected the tapered roller 3 between outer ring 1 and the inner ring 2, said tapered roller 3 also need be slidingly connected on the retainer usually; Said outer ring 1 is to the outer ring of outer lug cambered surface 4 with the surface of contact of tapered roller 3; Said inner ring 2 is the inner ring cambered surface 5 to outer lug with the surface of contact of tapered roller 3, and outer ring cambered surface 4 is identical with the curvature of inner ring cambered surface 5 usually, can adopt same grinding machine to carry out the grinding of outer ring cambered surface 4 and inner ring cambered surface 5; In sum, with the structure basically identical of existing general-utility car hub bearing.
The innovative point of the automobile hub bearing of the utility model is that mainly the circumferential surface of said tapered roller 3 is the roller cambered surface 6 to outer lug.Bigger relative drift angle can be produced owing to being made as the circumferential surface of tapered roller 3, thereby the curvature of outer ring cambered surface 4 and inner ring cambered surface 5 can be reduced to roller cambered surface 6 outer rings 1 of outer lug and the axis of inner ring 2.In practical application, the curvature of roller cambered surface 6 can be done slightly forr a short time with the curvature of inner ring cambered surface 5 than outer ring cambered surface 4.
Claims (1)
