Abstract
The utility model discloses a taper roller automobile hub bearing, which comprises an outer ring, an inner ring and a plurality of taper rollers connected between the inner ring and the outer ring in a rolling manner; the contact face of the inner ring, the outer ring and the taper roller is an outwards bumped arc face, the arc face is divided into a middle arc face, and two edge arc faces arranged at two ends of the middle arc face, the radius of the middle arc face is R, the radius of the edge arc face is r, R is greater than r. With the adoption of the taper roller automobile hub bearing, the contact face of the inner ring, the outer ring and the taper roller is set as three sections of arc faces which has small curved ratio in middle, and large curved ratio at two edges, so that the middle arc face with large radius and small curved ratio can be used for bearing larger radial load, the edge arc face with smaller radius and larger curved ratio can be used for ensuring a certain quantity of relative angle of deviation on the axis of the inner ring and the outer ring.
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 tapered roller 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 tapered roller automobile hub bearing, comprise that outer ring, inner ring and several rollings are connected the tapered roller between outer ring and the inner ring, and the surface of contact of said outer ring and inner ring and tapered roller is the cambered surface to outer lug; Cambered surface and two limit cambered surfaces that are distributed in middle cambered surface two ends in the middle of said cambered surface is divided into one; The radius of cambered surface is R in the middle of said, and the radius of said limit cambered surface is r, R r.
The width of cambered surface is the 70%-90% of cambered surface overall width in the middle of said.
In the middle of said the radius R of cambered surface be the limit cambered surface radius r 20-50 doubly.
Adopted the tapered roller automobile hub bearing of the utility model; Owing to curvature in the middle of being made as the surface of contact of outer ring and inner ring and tapered roller is little; Three sections cambered surfaces that two limit curvature are big; Radius is big, the less middle cambered surface of curvature can be born bigger radial load, and the limit cambered surface that radius is less, curvature is bigger can guarantee that a certain amount of relative drift angle can appear in the axis of inside and outside circle.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the local structure for amplifying schematic representation of the utility model.
Among the figure: 1-outer ring, 2-inner ring, 3-tapered roller, 4-cambered surface, cambered surface in the middle of the 5-, 6-limit cambered surface.
Embodiment
As depicted in figs. 1 and 2; The utility model discloses a kind of tapered roller 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, and the surface of contact of said outer ring 1 and inner ring 2 and tapered roller 3 is the cambered surface 4 to outer lug; In sum, with the structure basically identical of existing common tapered roller automobile hub bearing.
The innovative point of the tapered roller automobile hub bearing of the utility model is that mainly said cambered surface 4 is divided into a middle cambered surface 5 and two limit cambered surfaces 6 that are distributed in middle cambered surface 5 two ends, and the radius of said middle cambered surface 5 is R, and the radius of said limit cambered surface 6 is r, R r.Two limits of cambered surface 5 in the middle of two limit cambered surfaces 6 are symmetrically distributed in; And with middle cambered surface 5 smooth connections; In the middle of the radial force of bearing mainly acts on the cambered surface 5, the main effect of two limit cambered surfaces 6 is that tapered roller 3 also contacts on cambered surface 4 when guaranteeing that relative drift angle appears in the axis of inside and outside circle.
In practical application, the width of said middle cambered surface 5 is the 70%-90% of cambered surface 4 overall widths.The size of its width should be selected according to the difference of the suffered radial force size of bearing; When the radial force of bearing when bearing is big, said in the middle of the width of cambered surface 5 should select bigger, as adopting 90% width of cambered surface 4 overall widths as middle cambered surface 5; The radial force of bearing when bearing hour; The width of said middle cambered surface 5 should be selected less, and as adopting 70% width as middle cambered surface 5 of cambered surface 4 overall widths, the width of usually middle cambered surface 5 is chosen as and is 80% of cambered surface 4 overall widths.
In the middle of said the radius R of cambered surface 5 be limit cambered surface 6 radius r 20-50 doubly.When the ratio of the radius r of the radius R of middle cambered surface 5 and limit cambered surface 6 was big more, during like R=50r, the curvature of middle cambered surface 5 was more little; Its radial force that can bear is big more; Otherwise, when the ratio of the radius r of the radius R of middle cambered surface 5 and limit cambered surface 6 more hour, during like R=20r; The curvature of middle cambered surface 5 is big more, and its radial force that can bear is more little.
