Abstract

A power generating bearing assembly (100) comprising a power generating subassembly (200, 300, 400) integrated into a bearing (110). The power generating subassembly (300, 400) 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 system (130) is attached to one of the bearings (112, 116). The power generating subassembly (300, 400) includes an electrical generator (310, 410) in operational engagement with a magnetically polarized material (324, 424). The electrical generator (310, 410) is attached to the non-sealing carrying bearing (112, 116). The magnetically polarized material (324, 424) can be attached directly to the sealing system (130) or carried by a magnetically polarized material mount ring (320). The relative motion between the rings (112, 116) engages the electrical generator (310, 410) and the magnetically polarized material (324, 424) causing a generator core (312, 412) of the electrical generator (310, 410) to create an electrical current.

Description

technical field [0001] The invention relates to a device and method for generating electricity during bearing movement. Background technique [0002] A bearing can be defined as any of various mechanical elements that restrict relative motion between two or more components to only the desired type of motion. Typically, this allows and facilitates free rotation about the longitudinal axis and / or inhibits any linear movement of the component in a direction relative to the normal to the bearing. Bearings can be broadly classified according to the motion they allow and according to their principle of operation and the direction of applied loads they can handle. [0003] Bearings experience considerable use, which causes wear on the various bearing components. Over time, bearing wear can lead to mechanical failure. Mechanical failures may affect rotational motion and / or axial linear constraints. Failure to control any of these movements can lead to catastrophic failure of the...
