Abstract
A clutch assembly includes a first member for mechanically coupling to an output shaft. A first material is frictionally coupled to a first side surface of the first member. A second material is frictionally coupled to a second side surface of the first member. A compliant member is configured to apply an axial force on at least one of the first material and the second material. A radial spring least partially surrounds an exterior surface of the first member.
Claims15
A clutch assembly comprising:
- a housing;
- a harmonic drive at least partially positioned within the housing, the harmonic drive including:
- a wave generator configured to mechanically couple to an input shaft,
- a flex spline fixed with respect to the housing, and
- a circular spline arranged to rotate at a different speed than the wave generator when the wave generator rotates;
- a first pad frictionally coupled to a distal side surface of the circular spline;
- a second pad frictionally coupled to a proximal side surface of the circular spline;
- a compliant member configured to apply an axial force on the first pad and the second pad;
- and
- a radial spring surrounding an exterior surface of the circular spline, the radial spring comprising a bushing lining.
