Bearing

Abstract

A bearing comprises an inner ring, an outer ring surrounding the inner ring, a plurality of rolling bodies arranged between the inner ring and the outer ring, and check rings arranged at the two axialends of the inner ring; the two axial ends of the inner ring are provided with blocking edges protruding outwards in the radial direction of the bearing; the inner ring and the outer ring rotate relative to each other through the rolling bodies, and a blocking edge at each end faces the corresponding rolling body in the axial direction of the bearing; and each check ring surrounds the corresponding blocking edge and faces all the rolling bodies in the axial direction of the bearing. The check rings can increase the height of the blocking edges in the radial direction of the bearing, the installing gaps between the blocking edges and the outer ring are reduced, it is prevented that the rolling bodies flee to the exterior of the bearing and fall off from the installing gaps, and the bearingstructure is kept stable.

Description

Technical field [0001] The invention relates to the technical field of bearings, in particular to a bearing. Background technique [0002] An existing spherical roller bearing includes: an inner ring; an outer ring surrounding the inner ring; and a plurality of rolling elements located between the inner ring and the outer ring. The inner ring and the outer ring rotate relatively through the rolling elements. [0003] Generally, the inner ring is provided with ribs protruding outward in the radial direction of the bearing at both ends of the axial direction. The ribs face all the rolling elements in the axial direction of the bearing, and the ribs play a role in blocking the leakage of lubricant inside the bearing. When the bearing is assembled, it is necessary to insert the rolling elements from the outside of the bearing into the radial gap between the inner ring and the outer ring after the outer ring surrounds the inner ring. This requires that the height of the rib along the r...

AI Technical Summary

Problems solved by technology

This requires that the height of the rib along the radial direction of the bearing should not be too large, so as not to block the rolling elements and cause the rolling elements to fail to assemble

[0004] However, since the height of the rib along the bearing radial direction is small, it cannot effectively block the rolling elements, so this bearing has the problem that the rolling elements escape and fall off from the gap between the rib and the outer ring
