Title:
BEARING AND POWER TRANSMISSION DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP2015075183
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent abrasion of a specific part by displacing rolling elements little by little by utilizing very small differential rotation of inner and outer rings in an operating state keeping a ratio.SOLUTION: A bearing includes an outer ring, an inner ring disposed inside of the outer ring coaxially with the outer ring, a plurality of rolling elements disposed between an inner peripheral face of the outer ring and an outer peripheral face of the inner ring, and a retainer for retaining the plurality of rolling elements. The retainer includes a contact portion kept into contact with the inner peripheral face of the outer ring or the outer peripheral face of the inner ring. The contact portion is constituted so that frictional resistance by contact with the inner peripheral face of the outer ring or the outer peripheral face of the inner ring is different between a time when the outer ring or the inner ring rotates in one rotating direction, and a time when it rotates in the other direction.
