ABSTRACT:
A transmission apparatus includes an input shaft; an output shaft; a ring gear having internal ring gear teeth and having a ring gear central axis; a ring gear constraining structure constraining the ring gear to move translationally along a substantially circular path about the input shaft rotational axis without rotating about its own central axis relative to the apparatus; a mechanism for continuously changing the distance between the ring gear central axis and the input shaft rotational axis; a pinion gear having a diameter smaller than the inner diameter of the ring gear and retained with the ring gear so that its rotational axis is parallel with the ring gear central axis; and held in engagement with the ring gear teeth by a pinion gear constraining structure rotationally connected to an apparatus output shaft; where each time the input shaft rotates one revolution, the ring gear constraint structure moves the ring gear one revolution translationally along the circular path around the input shaft rotational axis, and the distance between the input shaft rotational axis and the ring gear central axis defines the diameter of the circular path over which the pinion gear travels during a single input shaft revolution, and thus defines the distance over which the pinion gear rolls for each revolution.
