Aligning roller bearing and bearing assembling

Abstract

The embodiment of the invention provides an aligning roller bearing and a bearing assembling. The aligning roller bearing comprises an outer ring, a first aligning ring and a second aligning ring; theouter ring surface of the outer ring comprises a first wing surface, a main surface and a second wing surface; the surface where the first wing surface is positioned and the surface where the secondwing surface is positioned are the same spherical surface; the main surface is suitable for being in contact with the inner ring surface of a bearing seat; the first aligning ring is arranged outsidethe outer ring in a sleeving manner; the inner ring surface of the first aligning ring is fit with the first wing surface; the second aligning ring is arranged outside the outer ring in the sleeving manner; and the inner ring surface of the second aligning ring is fit with the second wing surface. According to the aligning roller bearing provided by the embodiment of the invention, an aligning function can be realized, and moreover, the radial thickness of the aligning rings and the outer ring can be reduced, so that the sizes of rollers of the aligning roller bearing are increased within limited space, thereby improving the radial bearing capacity of the aligning roller bearing.

Description

technical field [0001] The embodiments of the present invention relate to the field of bearings, in particular to a spherical roller bearing and a bearing assembly. Background technique [0002] Spherical roller bearings are widely used in various fields of industry because of their good self-aligning function and the ability to compensate for coaxiality errors. [0003] Although the existing self-aligning roller bearings have a good self-aligning function, they generally have insufficient radial bearing capacity, so they cannot meet the requirements well. [0004] Therefore, how to improve the radial bearing capacity of the self-aligning roller bearing on the basis of satisfying the self-aligning requirements has become an urgent technical problem to be solved by those skilled in the art. Contents of the invention [0005] The technical problem solved by the embodiments of the present invention is how to improve the radial bearing capacity of the self-aligning roller bea...
