Embodiment Construction

[0026] Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present disclosure, but are not intended to exhaust all possible ways of the present disclosure, nor are they used to limit the scope of the present disclosure.

[0027] Such as figure 1 As shown, the present disclosure provides a radial roller bearing, which includes an outer ring 1 , an inner ring 2 , rolling elements 3 and a cage 4 . The rolling elements 3 are, for example, cylindrical rollers, tapered rollers, symmetrical spherical rollers, asymmetrical spherical rollers, etc., which have end faces in the axial direction A of the bearing.

[0028] The cage 4 is, for example, a riveted cage, in particular a riveted brass cage. The holder 4 includes a holder comb 41 and a holder cover 42 assembled together. The cage 4 has two sid...

Abstract

The invention provides a radial roller bearing, comprising an outer ring, a retainer and a rolling body. The outer ring is provided with two outer ring flanges arranged at intervals in the axial direction of the bearing; the rolling body is positioned in the axial direction through the two outer ring flanges; the retainer is provided with a pocket hole; and the axial size of the pocket hole is larger than the distance between the two outer ring flanges in the axial direction. Thus, when the rolling bodies rotate at a high speed, the axial end surfaces of the rolling body are not in contact with the axial inner end surfaces of edge beams of the retainer, so that friction force borne by the rolling body is reduced, the performance of the rolling bodies is improved, and the service life of the bearing is prolonged.

Description

technical field [0001] The disclosure relates to the technical field of bearings, and in particular to a radial roller bearing. Background technique [0002] Such as Image 6 As shown, in the radial roller bearing, the cage 8 (such as a two-piece brass cage (riveted brass cage)) is guided by the outer ring rib 9 in the radial direction, and is guided by the roller in the axial direction. Sub 10 to boot. [0003] During the operation of the bearing, the cage 8 will be in contact with the end face of the roller 10, such as cylindrical rollers and tapered rollers. The frame 8 has severe friction, which reduces the service life and performance of the bearings. Contents of the invention [0004] The present disclosure is made in view of the state of the prior art described above. The purpose of the present disclosure is to provide a low-friction radial roller bearing, wherein the end faces of the rollers are not rubbed by the cage, and the frictional force on the rollers is ...
