Abstract
Gear sets and methods for speed transformation are provided. In one aspect, an input gear is attached to an input motor shaft and a plurality of gear elements comprising an output element cooperatively engage the input gear, wherein a bearing means disposed about the input motor shaft supports the plurality of gear elements upon the motor shaft, the input motor shaft thereby functioning as a torque arm for the plurality of gear elements, the bearing means transferring an operational load comprising a total operative torque load of the gear set to an input motor through the motor shaft. In one aspect the bearing means comprises inner and outer high-speed bearings, and inner and outer disc bodies are disposed about the high-speed bearings and supported by the high-speed bearings. Embodiments include planetary gear and harmonic gear structures, and multistage gear sets.
