Title:
CAGE FOR SELF-ALIGNING ROLLER BEARING
Document Type and Number:
Japanese Patent JP2019173919
Kind Code:
A
Abstract:
To improve mass balance while suppressing the lowering of rigidity accompanied by the formation of an assembling notch at an outside diameter side of a cage, in the cage for a self-aligning roller bearing.SOLUTION: An inside diameter rib 13 is continuously arranged at an inside diameter face of a cage 10 so that a notch 12a coincides with a phase in a peripheral direction. Since an inside diameter side of a point in which the notch 12a is formed is expanded in a width and reinforced by the inside diameter rib 13, the lowering of the rigidity of the cage 10 caused by the notch 12a is suppressed. Also, since a mass which is lost due to the notching the notch 12a from the outside diameter rib 12 is compensated by the continuous arrangement of the inside diameter rib 13, the mass balance of the cage 10 in the peripheral direction can be improved.SELECTED DRAWING: Figure 1
