ABSTRACT:
This invention relates to high reduction planetary transmissions that do not use ring gears and particularly planet gears that are the support for the planet carrier. The planet carrier is entirely supported by the planet gears meshing with their respective sun and output gears. The planet gears can move in a radial direction to improve tooth alignment between the meshing gears and equalize the distribution of the torque load between the planet gears. In some cases the planet carrier may act as one of the support bearings for the input shaft.
