Abstract

A power generating bearing assembly (100) comprising a power generating subassembly (200) integrated into a bearing (110). The power generating subassembly (300, 400) utilizes the relative motion between an inner bearing ring (112) and an outer bearing ring (116) of the bearing (110) to generate electrical power. The power generating subassembly (300, 400) includes a generator drive member (310, 410) in operational engagement with an electrical generator (320, 420). The power generating subassembly (300, 400) is affixed to one of the bearing rings. A plurality of drive engaging members (130, 432, 434) is affixed to the opposite bearing ring in a spatial relationship at an equidistant radial location. The generator drive member (310, 410) is formed having a plurality of recessions (312, 412), which engage with drive engaging members (130, 432, 434). The relative motion between the rings (112, 116) engages the drive engaging members (130, 432, 434) and the generator drive member (310, 410) to rotate the electrical generator (320, 420) creating electrical current. The generator drive member (310, 410) can optionally be retained against the drive engaging members (130, 432, 434) by a biasing member (442).
