Rolling body of self-aligning roller bearing

Abstract

The invention discloses a rolling body of a self-aligning roller bearing. A through hole penetrating through two ends is formed in the middle of the rolling body along the axial line direction, and inclined surfaces are formed between two ends of the through hole and two end faces of the rolling body, and are in arc transition with the end parts of the through hole and the end faces of the rolling body. The rolling body is simple in structure and reasonable in design, and the defect of the core part of the rolling body can be effectively overcome; the rolling body is capable of generating trace elastic deformation when the self-aligning roller bearing suffers from extreme load impaction, so that the impact resistance of the bearing is improved, and the service life of the bearing is further prolonged.

Description

technical field [0001] The present invention relates to the technical field of bearings, in particular to a rolling body for a spherical roller bearing. Background technique [0002] In the prior art, the rolling bodies of spherical roller bearings are double-row drum rollers, such as figure 1 As shown, the rolling element 1 is a solid structure, and the two ends are machined with pockets 2. At present, large rolling elements are processed by forging. Due to the limitations of raw materials or forging processes, the core of the rolling elements is difficult to handle, has poor compactness, is prone to defects, and is prone to cracks and early failures in the later heat treatment process. The corners of the cavity are prone to cause stress concentration. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, the purpose of the present invention is to provide a rolling element for spherical roller bearing with reasonable structure design and long service l...
