Title:
TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/094795
Kind Code:
A1
Abstract:
A transmission device in which a ring-shaped first holding member is interposed between first and second transmission members, said first holding member having a plurality of holding holes uniformly restricting the interval between a plurality of first rolling bodies so as to suppress sudden random movements of the first rolling bodies inside first and second transmission grooves, when passing through a section of the grooves having a sudden change in curvature, and allow the first rolling bodies to roll smoothly. In the transmission device: the ring-shaped first holding member (R1) provided between first and second transmission members (5, 8) has a plurality of first holding holes (31) that uniformly restrict the intervals between and rotatably hold the plurality of first rolling bodies (23); each section of first and second transmission grooves (21, 22) is always open to the inner peripheral side or the outer peripheral side of the first holding member (R1); and lubricating oil is permitted to flow through these openings (IN1, IN2) to inside the first and second transmission grooves (21, 22). As a result, lubrication of a transmission groove inner surface and the rolling bodies can occur unhindered even if the first holding member is present.
