ROLLING BEARING
Document Type and Number:
WIPO Patent Application WO/2020/113514
Kind Code:
A1
Abstract:
A rolling bearing, comprising an outer ring (1), an inner ring (5), and a first rolling body (2) located between the outer ring (1) and the inner ring (5). The first rolling body (2) is designed as a tapered roller. The rolling bearing further comprises at least one second rolling body (6; 6'; 6'') located between the outer ring (1) and the inner ring (5), wherein the first rolling body (2) has a first self-rotation axis, and the second rolling body (6; 6'; 6'') has a second self-rotation axis. On at least one same axial position of the rolling bearing, the diameter of the second rolling body (6; 6'; 6'') in a cross section perpendicular to the second self-rotation axis is greater than the diameter of the first rolling body (2) in a cross section perpendicular to the first self-rotation axis. The rolling bearing is capable of preventing slippage when the load borne by the rolling bearing decreases.
