Title:
BEARING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/199689
Kind Code:
A1
Abstract:
A bearing device comprises: a rolling bearing (30) having a rotating ring (32), a fixed ring (31), and rolling elements (33); a preload-applying member (40); and a sensor unit (60). The rotating ring has a rotating ring raceway surface (32ca) extending along the circumferential direction. The fixed ring has a fixed ring raceway surface (31da) that extends along the circumferential direction and is opposite the rotating ring raceway surface with a gap therebetween in the radial direction. Rolling elements are disposed between the rotating ring raceway surface and the fixed ring raceway surface. The preload-applying member applies a preload to the rolling bearing along the axial direction. The sensor unit has a sensor (63) that is removably attached to either the rotating ring or the preload-applying member, and that senses the rotation state of the rotating ring.
