The actuating device has a centrally aligned input component, that transversely receives an output component through a central aperture, and is engaged with a driving mechanism. Torque is increased about the central output component as a series of axially aligned, but centrally offset, lobes push a corresponding driver disc around the central output at reduced velocity and increased torque. Each driver disc moves in eccentric fashion, yet remains engaged with a corresponding, centrally aligned take off member, each of which is further in combination with the central output component.

Abstract: A torque transmission device for providing steplessly variable torque conversion. The torque transmission device has a set of unidirectionally-rotatable, slotted levers radiating from a first axis, capable of engaging a torque output ring which is also rotatable on the first axis. An abaxial ring, which has studs that operate in the slots of the levers, is rotatable on a parallel second axis which can orbit the first axis. Torque input induces the second axis to orbit the first, and the force of orbital motion bears, through the abaxial ring, on at least one lever in a direction opposite its rotatable direction, holding it fixed, and also bears on at least one other lever in a direction that coincides with its rotatable direction, causing it to rotate. The fastest-rotating lever engages and drives the torque output ring. Varying the distance between the first and second axes varies the torque conversion ratio.

The carrier pin includes a crank portion that is eccentric by “e” relative to the axis center of the carrier pin with the eccentric angle being made variable. The planet gear is supported rotatably about the axis center of the crank portion.

Accordingly, the axial dynamic balance can be secured in every individual rotating element composing a gear device. The gear device is employed in the electrically driven actuator for the purpose of providing an electrically driven actuator with a low vibration and a property of high precision.

Abstract: This invention is a steplessly variable power transmission, comprising: an input driven planet gear, having axially disposed teeth, confined to reciprocate in straight diametrical channels in a output driving ring gear. When the teeth also move on a straight line as related to the housing, no rotary drive can be placed on the output ring gear, and the transmission is in a neutral mode. But, when the teeth are forced to curve, as related to the housing, the output gear must rotate accordingly. For example: if the input driven teeth veer away one degree, from a straight line, while the input rotates a full 360 degree rotation, then the input-output ratio is 360 to 1 underdrive. When the teeth path is a circle, the ratio is 1 to 1, but, the extreme lows, allow built-in overdrive gearing. The preferred embodiment has a stepless range from neutral to 3 to 1 overdrive. There are numerous methods to curve the path of the input driven teeth.

The second member has an inwardly directed flange formation with oppositely inclined conical faces. The first and second members thereby define a pair of inwardly directed annular grooves the walls of which diverge inwardly. First and second annular discs are mounted for rotation about axes parallel to but eccentric of the axis of rotation of the input assembly, so that each disc engages in a different one of the grooves. Each disc engages the opposed conical walls of its associated groove so that drive is transmitted from the input assembly to each of the discs.

Abstract: A technique for modifying an input rotation in continuously variable increments to produce a controlled rotational output is disclosed herein. This technique combines epicyclic motion of a series of planetary shafts in a parallel fashion in order to produce continuous, controlled, intermediate output in the same direction and at the same speed or a greater speed than the input rotation. This intermediate output is then modified to produce a continuous, controlled, final rotational output only when the intermediate output is greater in speed than the input. The final output can be in the same direction as the rotational input and at a speed which is proportionate to the excess speed of intermediate output.
