Abstract:
1. A gear set, comprising: an input gear attached to an input motor shaft, the input gear comprising a plurality of gear teeth; a plurality of gear elements cooperatively engaging the input gear teeth and comprising an output element, the plurality of gear elements configured to translate a first motor shaft input gear revolution speed into a second output element output revolution speed and a first input torque into a second output element torque; and a bearing means disposed about the input motor shaft and configured to support the plurality of gear elements upon the motor shaft, the bearing means thereby transferring an operational load of the gear set to an input motor through the motor shaft, the operational load comprising a total operative torque load of the gear set; wherein the bearing means comprises inner and outer high-speed bearings; and the plurality of gears further comprises: an inner disc body defining a central aperture, the inner disc body aperture disposed about the inner high-speed bearing and the inner disc thereby supported by the input shaft through cooperative engagement with the inner high-speed bearing; and an outer disc body defining a central aperture and axially spaced relative to the input shaft from the inner disc body, the output element is affixed to the outer disc body, the outer disc body aperture disposed about the outer high-speed bearing and the outer disc body and output element thereby supported by the input shaft through cooperative engagement with the outer high-speed bearing.
