Abstract
The utility model discloses a bearing conical roller, which aims to provide a bearing conical roller which rotates flexibly and has long service life. The bearing conical roller adopts the technical scheme that the bearing conical roller comprises a cone body, wherein the end surface of the big end of the cone body is an arched surface. The bearing conical roller has the advantages of flexible rotation and long service life as compared with the prior art.
Description
Technical field:
The utility model relates to a kind of bearing, particularly a kind of bearing tapered roller.
Background technique:
The tapered roller that existing thrust-bearing uses, its large end face is the plane, and in use the rubbing surface of this plane and rib increases, and the flexibility of rotation is affected, and causes bearing life to reduce.
Summary of the invention:
The utility model purpose provides a kind of bearing tapered roller that rotates flexible long service life.The technical solution of the utility model is that a kind of bearing tapered roller comprises cone, it is characterized in that: the end face of the big termination of cone is an arc shaped surface.The utility model has the advantage of rotating flexible long service life compared with the prior art.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The utility model is described in further detail in conjunction with above-mentioned accompanying drawing, for overcoming the defective of existing roller and rib friction increase, the large end face 1 of tapered roller made arc shaped surface, reduced frictional force, moves it more flexibly, prolonged working life of roller.
