Abstract
A flexible band-gear system has an ring gear assembly with bands in electrical contact with and a ring gear in mechanical engagement with corresponding bands and gears of planet gear assemblies which are in turn in electrical contact and geared engagement with a sun gear assembly mounted to a rotating shaft. Electrical power and/or an electrical signal can thus be conducted across a rotating joint which also transfers mechanical power. The flexible band-gear system can also be used in linear applications to transfer electrical power/signal via rolling contact with a linear band. The geared aspect of the system simplifies axial alignment and maintains the relative positions (within the ring annulus) of the planet gears. Electrical power and signal capacity can be varied with the number of planet gears in the system. Multiple channels are added using segmented contact bands and/or multiple contact band layers.
