    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 gear reducer and a juicer including the gear reducer are disclosed. The gear reducer transfers rotational force, provided by a drive unit, to a juice extraction screw assembly after gear reduction. The gear reducer includes one or more gear reduction units. At least one of the one or more gear reduction units includes a sun gear coaxially connected to a rotating shaft of the drive unit; a ring gear configured such that a plurality of gear teeth are formed on the inner circumferential surface thereof around the sun gear, and configured to output a rotation speed slower than the rotation speed of the sun gear; and a plurality of planetary gears disposed between the sun gear and the ring gear, and configured to transfer the rotational force of the sun gear to the ring gear.

    摘要： A radially stacked planetary gear assembly provides improved lubrication fluid flow to the planet gear bearings of an outer planetary gear set which is especially important when the housing or outer planetary gear carrier is stationary. The assembly includes radially aligned or stacked inner and outer planetary gear sets each having a sun gear, a ring gear and a carrier having planet gears in constant mesh with the sun and ring gears wherein the ring gear of the inner gear set is also the sun gear of the outer gear set and the outer carrier is the assembly housing. The sun gear is disposed on a transmission shaft having lubrication passages which aligns with pluralities of radial openings in a hub housing. A circular plate or guide adjacent one side of the housing includes channels which align with the openings and functions as a lubrication director, channeling lubrication from the transmission shaft and the pluralities of radial openings in the housing hub to the outer bearings, shafts and planet gears.

    摘要： A driving force transmission device includes a sun gear that rotates upon receipt of a driving force, an internal gear that has a hollow portion and internal teeth on an inner surface of the hollow portion, the internal gear being disposed coaxially with the sun gear, a planetary gear that rotates and revolves in mesh with the sun gear and the internal gear, a rotating member that supports a rotating shaft of the planetary gear, and rotates about an output shaft as the planetary gear revolves, and a retaining member that contacts with one end of the rotating shaft of the planetary gear on one surface side of the rotating member to retain the rotating shaft.

    摘要： A planetary gear assembly is provided, comprising a first planetary gear stage and a second planetary gear stage. The first planetary gear stage comprises a first sun gear, first planet gears and an outer ring gear, and the second planetary gear stage comprises a second sun gear, second planet gears and one or more output ring gears. The outer ring gear and the second sun gear are the same component, and the first planetary gear stage is located within the second planetary gear stage.
