Title:
ROLLING BEARING
Document Type and Number:
WIPO Patent Application WO/2023/187919
Kind Code:
A1
Abstract:
This rolling bearing comprises: a steel outer race; a steel inner race which has a shared center axis with the outer race and is disposed on the inner circumferential side of the outer race; and a plurality of rolling elements which are disposed so as to be capable of rolling on the inner circumferential surface of the outer race and the outer circumferential surface of the inner race. The outer race includes a first outer race and a second outer race which is fixed to the first outer race and disposed side by side with the first outer race in a first axial direction, which is the direction in which the center axis extends. The inner race includes a first inner race, and a second inner race which is fixed to the first inner race and disposed side by side with the first inner race in the first axial direction. The first outer race, the second outer race, the first inner race, and the second inner race each have a first part, a second part, and a third part. The first part is an annular disc part that extends in a direction orthogonal to the first axial direction. The second part is connected to the first part, and a circumferential surface thereof constitutes an annular rolling surface. The third part is a tubular part that is connected to the second part and extends along the first axial direction. An end face of the third part of the first inner race and an end face of the third part of the second inner race are opposite from and spaced from the inner circumferential surface of the third part of the first outer race and the inner circumferential surface of the third part of the second outer race, respectively.
