    Abstract: A rotary actuator is provided which includes a prime mover including a rotor and a stator; a front-end star compound gear equipped with a first pinion, a first plurality of star gears arrayed concentrically around said first pinion, a first clutch, a first clutch shift motor, an output shaft, and first, second and third gears, wherein said third gear is attached to said output shaft; a back-end star compound gear; and a wheel interface including a principal bearing and a brake disk. The first pinion drives said the clutch. The first clutch shift motor shifts the first clutch between a first position in which the first clutch engages the first gear, and a second position in which the first clutch engages the second gear. When the first clutch engages the first gear, the first gear drives the first plurality of star gears. When the first clutch engages the first gear, the first plurality of star gears drive the third gear, or the first clutch engages the third gear to drive the output shaft directly.

    Abstract: A parallel eccentric electro-mechanical actuator provides motive power and includes an electric prime mover that drives the reducer's pinion gear. This pinion drives minimum three star gears with stationary shaft bearings. Each shaft contains an eccentric which are completely in parallel with each other. These eccentrics can be thought of as parallel/in-phase driven crankshafts. Each eccentric drives the parallel eccentric (PE) gear through a bearing. The PE gear exhibits a circular motion (without rotation) which in itself is unbalanced. The crankshafts have another eccentric which create an opposite inertia force to balance that of the PE gear. The PE gear contains an external toothed gear on its periphery. It meshes with the internal teeth of the output ring gear. The relative motion between the PE gear and the ring gear is that the PE gear rolls inside the ring gear. This relative motion is called hypo-cycloidal motion.

    Abstract: An orthotic or prosthetic actuator is provided which includes a parallel eccentric gear train which terminates on a first end in a first plate, and which terminates on a second end in a second, rotatable plate which is adjacent to the first plate. The actuator further includes a spring which is disposed between these adjacent plates. The actuator preferably utilizes Oldham coupling, by way of a pair of crosslinks disposed on each side of the motor, to restrain rotation of the dual parallel eccentric gears in the actuator, while permitting their linear oscillation. The crosslinks are preferably equipped with a tongue/spline lubrication system to provide continuous lubrication to the mated and loaded crosslink tongue and groove surfaces.
