摘要： A friction transmission device has a friction transmission mechanism that transmits power by contact between a take-out member from which output rotation is taken out and a plurality of friction rolling elements. The take-out member has a contact surface inclined with respect to an axial direction. The device includes an output member that is used to transmit the output rotation to a driven device, and a coupling that connects the take-out member and the output member to each other. The coupling is configured to be more easily deformed than the take-out member and the output member with respect to an axial load, and has a function of absorbing deviation of an axial center between the take-out member and the output member and a function of converting a torque acting on the output member into an axial force to transmit the axial force to a take-out member side.

摘要： A planetary gear device includes: a first internal gear and a second internal gear, a first external gear which meshes with the first internal gear, a second external gear which meshes with the second internal gear, and an eccentric body which circumferentially moves the first external gear and the second external gear. The first external gear and the second external gear each independently have external teeth and are connected to each other to integrally rotate with each other, the first internal gear and the second internal gear each independently have internal teeth, one of the first internal gear and the second internal gear is connected to a stationary side, and the other thereof is connected to an output side, and each of the first internal gear and the second internal gear has internal teeth which are constituted by a support body, and a rotating body rotatable to the support body.

摘要： Provided is a friction transmission device including an input raceway ring, a planetary rolling element that is disposed around a rotation axis of the input raceway ring and comes into contact with the input raceway ring; an output raceway ring that comes into contact with the planetary rolling element and is connected to an output shaft, and a first support raceway ring and a second support raceway ring that come into contact with the planetary rolling element. A quadrangle is formed by extension lines of normal vectors at contact points between the planetary rolling element and the respective raceway rings.
