Abstract

The utility model discloses a conical roller bearing. The conical roller bearing is technically characterized by comprising an outer ring, an inner ring, a retainer and a conical roller, wherein the retainer is arranged between the inner ring and the outer ring, the conical roller is arranged on the retainer, and the outer ring is provided with a conical roller raceway. The conical roller bearing is characterized in that the inner ring is provided with a raceway trough matched with the conical roller, the two sides of the raceway trough are provided with a large flange and a small flange, the conical roller is in the shape of a circular truncated cone and comprises large and small end faces, the large end face of the conical roller is provided with an arc raised part, the large flange butts against the arc raised part on the conical roller, and the arc raised part covers the whole large end face of the conical roller. Through arranging the arc raised part on the large end face of the conical roller, the contact between the large flange and the large end face is changed from a surface-surface contact mode to a line-surface contact mode, thereby reducing friction and abrasion, ensuring the stressed stability of the conical roller, improving the utilization stability of the bearing, and prolonging the service life of the bearing.

Description

Tapered roller bearing
Technical field
The utility model relates to field of bearings, and more particularly, it relates to a kind of tapered roller bearing.
Background technique
It is radially main footpath, axial connected load that tapered roller bearing mainly bears, and tapered roller bearing is widely used in all kinds of machinery, in automobile car, wheel hub, is widely used especially.
Tapered roller bearing mainly is comprised of outer ring, inner ring, tapered roller, retainer at present, retainer is located between inside and outside circle, retainer is for keeping tapered roller fixing orderly arranging of track in circle, in order to realize the stability of tapered roller at inner ring raceway and outer ring raceway, often open a raceway groove, can realize spacing to tapered roller, but exist tapered roller bottom surface and flange friction serious, cause unbalance stress, bearing is unstable, affects the tapered roller bearing problem in working life.
The model utility content
The deficiency existed for prior art, the utility model provides a kind of tapered roller bearing, and it can effectively evade friction between prior art middle (center) bearing tapered roller and flange, wearing and tearing, causes unbalance stress, unsettled problem.
For achieving the above object, the utility model provides following technological scheme: a kind of tapered roller bearing, comprise outer ring, inner ring, retainer, tapered roller, be provided with retainer between inner ring and outer ring, retainer is provided with tapered roller, described outer ring is provided with tapered roller raceway, it is characterized in that: described inner ring is provided with the raceway groove suitable with described tapered roller, described raceway groove both sides are provided with large flange, little flange, described tapered roller is round table-like, comprise large, little both ends of the surface, described tapered roller large end face is provided with the arcuation protuberance, arcuation protuberance on described large flange and described tapered roller is inconsistent, described arcuation protuberance covers whole tapered roller large end face.
By adopting technique scheme, change tapered roller and the way of contact of flange greatly, with the tapered roller of cambered surface, make contacting between original face and face change to contacting of line and face, reduce the area of contact, reduce friction, the wearing and tearing of tapered roller, the unbalance stress that can seriously not cause because of the tapered roller concentrated wear, be conducive to the stable of tapered roller, significantly promotes the service life of tapered roller bearing.
The utility model preferably is set to: be equipped with wearing layer on described retainer and tapered roller, described wearing layer is the titanizing layer.
By adopting technique scheme, equally also there are friction, wearing and tearing between retainer and tapered roller, technology for plating titanium, belong to coating technique, it is excellent that technology for plating titanium has simply, practical, effect is good etc., after the retainer titanizing, under film hardness HV ≈ 1500, equal conditions, than wear-resisting 150 times of plating 22K gold, significantly promote the wear resistance of retainer and tapered roller.
The accompanying drawing explanation
The structural representation that Fig. 1 is a kind of tapered roller bearing embodiment of the utility model.
1-outer ring in figure, 2-inner ring, 3-retainer, 4-tapered roller, 5-raceway groove, the little flange of 6-, the large flange of 7-, 8-small end face, 9-large end face, 10-arcuation protuberance.
Embodiment
With reference to Fig. 1, the embodiment of a kind of tapered roller bearing of the utility model is described further.
A kind of tapered roller bearing, comprise outer ring 1, inner ring 2, retainer 3, tapered roller 4, be provided with retainer 3 between inner ring 2 and outer ring 1, retainer 3 is provided with tapered roller 4, described outer ring 1 is provided with tapered roller raceway, described inner ring 2 is provided with the raceway groove 5 suitable with described tapered roller 4, described raceway groove 5 both sides are provided with large flange 7, little flange 6, described tapered roller 4 is round table-like, comprise large end face 9, small end face 8, described tapered roller large end face 9 is provided with arcuation protuberance 10, described large flange 9 is inconsistent with the arcuation protuberance 10 on described tapered roller 4, described arcuation protuberance 10 covers whole tapered roller large end face 9, be equipped with wearing layer on described retainer 3 and tapered roller 4, described wearing layer is the titanizing layer.
Before bearing working, in order to guarantee tapered roller 4 and outer ring 1, the raceway close contact of inner ring 2, must give pretightening force of bearing, pretightening force acts on respectively the large end face of bearing outer ring 1 and the large end face of inner ring 2, make arcuation protuberance 10 on tapered roller 4 contact at the very start with large flange 7, when bearing working, tapered roller, outer ring, inner ring rotates, aggravation arcuation protuberance 10 and contacting between flange 7 greatly, described arcuation protuberance 10 can be to cover whole tapered roller large end face 9, the part that can be also contact between arcuation protuberance 10 and large end face 9 makes arcuation into and gets final product, changed contacting of traditional face and face, reduced friction, wearing and tearing, improve the stability that bearing uses, increase the service life.
Above a kind of novel tapered roller bearing that the utility model embodiment is provided is described in detail, and for one of ordinary skill in the art, the thought according to the utility model embodiment, all will change in specific embodiments and applications.In sum; this description should not be construed as restriction of the present utility model; other any any variation and modification of doing according to the constructed thought of the utility model and scope of patent protection or be equal to enforcement, be scope of patent protection of the present utility model and contain.
