    摘要: A rotary actuator (101) is provided which includes a crankshaft (103), first and second eccentric gears (121), first and second end plates (123), a first crosslink (117) which is disposed between the first eccentric gear and the first end plate, a second crosslink which is disposed between the second eccentric gear and the second end plate, a stator (113) disposed between the first and second eccentric gears, and a rotor (109). Preferably, the rotary actuator further includes first and second support plates (115) which are disposed concentrically about the crankshaft and which are attached to first and second surfaces of the stator, respectively. The foregoing configuration allows the stator to serve as a major structural element, which may enhance the stiffness and reduce the weight of the actuator, while simplifying many of its active components.

    摘要: 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.

    摘要: 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.

    摘要: A self-contained rotary actuator provides motive power in automated mechanical systems and includes a cross-roller bearing operating as a structural joint. An outer attachment shell rigidly interfaces the automated mechanical system and contains a motor stator and an internal bull gear. The internal bull gear interfaces the cross-roller bearing and provides stiffness and includes internal gear teeth. An output attachment plate mechanism includes an internal ring gear and supports drive shaft bearings. The internal ring gear rigidly interfaces the output attachment plate and includes internal gear teeth. A drive shaft holds a prime mover rotor and an eccentric and associates with the output attachment plate via the drive shaft bearings. A gear train includes a meshing gear having external gear teeth with circular arc surfaces for meshing with the internal gear teeth of the internal bull gear and the internal gear teeth of the internal ring gear and walks a minimal number of the external gear teeth for each rotation of the prime mover rotor. The cross-roller bearing, the outer attachment shell, the drive shaft, and the meshing gear train provide a self-contained, integrated, actuation torque transmitting force from the prime mover along a shortest-possible transmission path.
