Document Type and Number:
WIPO Patent Application WO/2023/189614
Kind Code:
A1
Abstract:
A sensor-equipped bearing (100, 100A, 100B, 100C) comprises: a bearing (10) including a rotating ring (11), a fixed ring (12), and rolling element (13); and a sensor unit (20). The rotating ring has a rotating ring raceway surface (11da) extending along the circumferential direction. The fixed ring has a fixed ring raceway surface (12ca) that extends along the circumferential direction and is opposite the rotating ring raceway surface with a gap therebetween in the radial direction. The rolling element is disposed between the rotating ring raceway surface and the fixed ring raceway surface. The sensor unit is detachably attached to the fixed ring, and has: a power generating coil (22) that generates an induced voltage as the rotating ring rotates; a sensor (24) that outputs a physical quantity or chemical quantity as an electrical signal; and a wireless communication module (25) that wirelessly transmits the output of the sensor to the outside.
