Title: BEARING EMBEDDED POWER GENERATION CONFIGURATION
Abstract:
A power generating bearing assembly (100) comprising a power generating subassembly (200, 300) integrated into a bearing (110). The power generating subassembly (300) utilizes the relative motion between a bearing inner ring (112) and a bearing outer ring (116) of the bearing (110) to generate electrical power. A sealing member (136) is attached to one of the bearings (112, 116) at one end thereof. The power generating subassembly (300) includes an electrical generator (320) assembled through an aperture (137) of the sealing member (136) within an interior section of the bearing (110) and positioned to be in operational engagement with a magnetically polarized material (324). The magnetically polarized material (324) is integrated into a magnetic ring (138), which is attached to the non-seal carrying bearing ring. The relative motion between the rings (112, 116) engages the electrical generator (310) and the magnetically polarized material (324) causing a generator core (312) of the electrical generator (320) to create an electrical current.
