Title:
POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/216185
Kind Code:
A1
Abstract:
The present invention provides a power transmission device (10) that is capable of mechanically cutting torque. This power transmission device (10) is provided with: an input member (12) and an output member (16) with a plurality of rollers (18) interposed therebetween; a first cam (30) coupled to the input member (12) or the output member (16); a second cam (40) that faces the first cam (30) and is restricted in movement in the axial direction; and a spring (43) that applies an elastic force so as to separate the cam surfaces from each other. The first cam (3) and the second cam (40) are engaged with each other when the elastic force, which is a product of the mass of the second cam (40) and the absolute value of the acceleration of the first cam (30) in the rotation direction as seen from the second cam (40), is greater than the elastic force of the spring (43).
