Title:
REDUCTION BEARING AND ELECTRIC MOTOR
Document Type and Number:
Japanese Patent JP2018159468
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To increase a bearing performance of a conventional reduction bearing and to reduce the total size of the reduction bearing.SOLUTION: An inner ring (3), a center ring (2) and an outer ring (1) are concentric around a rotational symmetry axis (50). A first ring of a plurality of rolling elements (4a) and a second ring of a plurality of rolling elements (4b) are further disposed. Two rings of the plurality of rolling elements (4a, 4b) are centered around the rotational symmetry axis (50) and located between the inner ring (3) and the outer ring (1). The inner ring (3) and the outer ring (1) are configured to have radial bearing races (8a, 8b) for both of two rings of the plurality of rolling elements (4a, 4b). A reduction bearing (31) is configured to transmit a wave-like reduction action between the center ring (2) and either the inner ring (3) or the outer ring (1) via axial displacement of the plurality of rolling elements (4a, 4b) of at least one of the two rings of the plurality of rolling elements (4a, 4b).SELECTED DRAWING: Figure 1
