Abstract
The utility model relates to a novel tapered roller bearing, which comprises a bearing inner race, a roller and a bearing outer race, wherein a circle of the roller is arranged between the bearing inner race and the bearing outer race; a retainer is arranged in the axial direction of the roller; the retainer is located between the bearing inner race and the bearing outer race; a small flange and a large flange are arranged in the bearing inner race; the large flange is in close contact with one end face of the roller; the portion where the large flange is in contact with the roller end face is an extended convex block; and the thickness of the large flange is increased by 3-40% based on the original flange design. The utility model has the benefits that as the large bearing flange is a main loading area of axial force, the flange strength is very important; to prevent that when meeting too large axial force, the flange is broken, the design is optimized and the large baffle thickness is reinforced; the thickness of the large flange is increased by 3-40% based on the original flange design, thus the axial loading capacity of the large flange is effectively improved; and the novel tapered roller bearing has the characteristics of good safety and long service life.
Description
Technical field
The utility model relates to a kind of tapered roller bearing, relates in particular to the reinforced novel tapered roller bearing of a kind of large-flange.
Background technique
Tapered roller bearing can be applicable to pure radial force, pure axial force, and radial and axial federated environment, but no matter which kind of receives force environment, and this class bearing large-flange all receives axial force, drives the rolling element rotation.
This class bearing is widely used in not only playing transmission, supporting role in all kinds of automobiles and the engineering machinery, and early warning is more arranged, occurs bigger loss when avoiding auto parts to lose efficacy; This class bearing large-flange is the main loading zone of axial force, its rib intensity outbalance.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of above-mentioned existence, and provides a kind of rib intensity high novel tapered roller bearing.
The purpose of the utility model is accomplished through following technological scheme; It comprises bearing inner race, roller, retainer, bearing outer ring; Be provided with a circle roller between described bearing inner race and bearing outer ring; This roller axially on be provided with retainer, and this retainer is positioned between bearing inner race and bearing outer ring.
As preferably, be provided with little rib and large-flange in the described bearing inner race, large-flange closely contacts with an end face of roller.
As preferably, the part that described large-flange contacts with roller end face is one to extend the fritter of convex shape, and the thickness of this large-flange is to increase 3%-40% on the former large-flange base of design.
The beneficial effect of the utility model is: be the main loading zone of axial force because of the bearing large-flange; Its rib intensity outbalance; Occur the rib fracture when preventing larger axial force, optimal design is strengthened large-flange thickness, makes large-flange thickness on former base of design, increase by 3%～40%; Effectively improve large-flange axial load ability, have that Safety performance is good, the characteristics of long service life.

Label in the accompanying drawing is respectively: 1, bearing inner race, 2, roller, 3, retainer, 4, bearing outer ring, 11, little rib, 12, large-flange, 121, fritter.
Embodiment
To combine accompanying drawing that the utility model is done detailed introduction below: shown in accompanying drawing 1; The utility model comprises bearing inner race 1, roller 2, retainer 3, bearing outer ring 4; 4 of described bearing inner race 1 and bearing outer rings are provided with a circle roller 2; This roller 2 axially on be provided with retainer 3, and this retainer 3 is positioned at 4 of bearing inner race 1 and bearing outer rings.
Shown in accompanying drawing 2, be provided with little rib 11 and large-flange 12 in the described bearing inner race 1, large-flange 12 closely contacts with an end face of roller 2.The part that described large-flange 12 contacts with roller 2 end faces is the fritter 121 of an extension convex shape, and the thickness of this large-flange 12 is to increase 3%-40% on the former large-flange base of design, effectively improves large-flange axial load ability.
Except that the foregoing description, all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
