  • Patent number: 9879760
    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.

  • Patent number: 8821331
    Abstract: A speed/torque enhancing power transmission is disclosed that translates slow rotating, high torque motion to high rotation, low torque motion or alternatively high rotating low torque motion to low rotating high torque motion and is suitable as a speed increaser for use in a device like a wind turbine. As a speed increaser the transmission has certain advantages, such as reduced weight and/or size compared to other units having the same performance characteristics. The speed increaser employs a pair of externally toothed spur gears orbiting in a non-rotating manner 180° out of phase inside an internally toothed ring gear. The input drives the ring gear and the orbiting spur gears drive separate eccentrics on the output shaft extending in opposite directions to provide dual output. In one embodiment, cross guide projections on the spur gear and cross guide projections on the housing engage slots in a swash plate.

  • Patent number: 8801559
    Abstract: A vehicular power transmitting system including an oil pump constructed to sufficiently reduce a required drive torque. A high-pressure-port discharge amount of first and second high-pressure passages of the oil pump is determined such that an amount of consumption of working oil of relatively high pressure can be afforded only by the high-pressure-port discharge amount, during steady-state running of a vehicle in which engine speed is not lower than a predetermined threshold value corresponding to a predetermined lowest target input shaft speed of a continuously variable transmission for its shifting control. The pressure of the working oil discharged from first and second low-pressure discharge passages is kept at a predetermined low level, and the required drive torque of the oil pump is sufficiently reduced.

  • Patent number: 8789455
    Abstract: Drive mechanism for the conversion of oscillatory motion into rotating motion or vice versa by means of a non-circular gear train, in a system composed of arcuate pistons solidly fixed to a rotor which is able to oscillate about its axis inside a stator. The mechanism comprises a set of non-circular internal and external toothed gears coupled in a fashion similar to that of two epicyclic gearings joined by their respective planet gears, although there are not any sun gears in the present arrangement. All the gears cooperate so as to produce the sought motion conversion between the pistons and the planet carriers and the drive shaft attached thereon. Its field of application includes therefore any device that uses variable volume chambers as a means to transmit energy to, or obtain energy from, a working gas, such as compressors, pneumatic motors or internal combustion engines.
