DETECTION DEVICE

WIPO Patent Application WO/2023/171238

A1

This detection device comprises a base part (42) and a bearing (50). The bearing has an outer ring member (51), an inner ring member (52), and rolling bodies (53) provided between the outer ring member and the inner ring member. A first bearing member (52) which is one among the outer ring member and the inner ring member is fixed to a rotary body, and a second bearing member (51) which is the other is fixed to the base part. The detection device comprises: disk-like detection rotary parts (80, 83, 86) which are provided to rotate integrally with the first bearing member and extend outward in a radial direction of the bearing with respect to the first bearing member; and a displacement detection part (90). The displacement detection part is provided at a position which is separated from the bearing in the radial direction and which faces the detection rotary parts in the axial direction of the bearing. The displacement detection part outputs a voltage signal according to the axial displacement of the detection rotary parts and a displacement in a direction perpendicular to the axial direction.
