Abstract
The utility model belongs to the technical field of the bearing technique and specifically relates to a tapered roller bearing. The tapered roller bearing comprises a bearing, an outer ring, an inner ring, a retainer and rollers, wherein the outer ring and the inner ring are arranged on the bearing, the retainer is arranged between the inner ring and the outer ring, the rollers are arranged in the retainer, the outer ring raceway and the inner ring raceway protrude outwards, and the outer walls of the rollers protrude outwards. The outer ring raceway and the inner ring raceway of the tapered roller bearing protrude outwards to form a convexity bus, and the outer wall of the roller also protrudes outwards to form the convexity bus, so that stress concentration at the contact part of the edge of the roller and the raceway caused by deflection can be effectively prevented, and the service life of the bearing is prolonged.
Description
Technical field
The utility model relates to technical field of bearings, especially a kind of tapered roller bearing.
Background technique
The outer ring of present tapered roller bearing, inner ring and roller bus all are straight line, and it is concentrated to cause roller and roller and raceway contact point to produce stress easily, thereby influence the working life of bearing.
The model utility content
In order to overcome existing tapered roller bearing short deficiency in working life, the utility model provides a kind of tapered roller bearing.
The utility model solves the technological scheme that its technical problem adopted: a kind of tapered roller bearing; Comprise bearing, outer ring, inner ring, retainer and roller; Said bearing is provided with outer ring and inner ring, is provided with retainer in the middle of said inner ring and the outer ring, is provided with roller in the said retainer; Said outer ring raceway and inner ring raceway outwards protrude, and said roller outer wall outwards protrudes.
The beneficial effect of the utility model is; The outer ring raceway of this tapered roller bearing and inner ring raceway outwards protrude the formation convex bus; The roller outer wall also outwards protrudes and forms convex bus; Can effectively prevent the roller deflection and produce roller edge and raceway contact point and produce stress and concentrate, improve bearing life.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the equipped schematic representation of the utility model outer ring, inner ring and roller.
Among the figure 1, bearing, 2, the outer ring, 3, inner ring, 4, retainer, 5, roller.
Embodiment
Like Fig. 1 is the structural representation of the utility model; A kind of tapered roller bearing comprises bearing 1, outer ring 2, inner ring 3, retainer 4 and roller 5, and said bearing 1 is provided with outer ring 2 and inner ring 3; Said inner ring 3 and the outer ring 2 middle retainers 4 that are provided with; Be provided with roller 5 in the said retainer 4, said outer ring 2 raceways and inner ring 3 raceways outwards protrude, and said roller 5 outer walls outwards protrude.
This tapered roller bearing; The raceway of outer ring 2 and inner ring 3 is processed into outside convex shape; The outer wall of roller 5 also is designed to the outer gibbosity that agrees with mutually with the raceway of outer ring 2 and inner ring 3; Can effectively prevent roller 5 deflections and produce roller 5 edges and raceway contact point and produce stress and concentrate, improve bearing life.
