Title:
CLUTCH DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/146776
Kind Code:
A1
Abstract:
Provided is a clutch device capable of reliably transmitting predetermined torque. Power is transmitted from an outer ring (10) to a second gear (13) through a first gear (12). The teeth (12a) of the first gear (12) are formed so that the lines of the teeth (12a) are non-parallel to the center axis (o). The direction of axial force generated by the reaction force of the second gear (13) and acting on the first gear (12) is set to be the same as the direction of movement of the outer ring (10). When rollers (8) engage with raceway surfaces (4a, 10a) and power is transmitted from the first gear (12) to the second gear (13), the reaction force of the second gear (13) promotes the movement of the outer ring (10) in the axial direction. Predetermined torque can be reliably transmitted because axial pull-in force between an inner ring (4) and the outer ring (10) increases.
