Document Type and Number:
WIPO Patent Application WO/2023/166567
Kind Code:
A1
Abstract:
A rolling bearing abnormality detection device for detecting an abnormality in a rolling bearing (1), said detection device being equipped with a detection member (15) provided along the inner-circumferential surface of an outer race (4) or along the outer-circumferential surface of an inner race (7) so as to be electrically insulated relative to a first-side detection member on one side in the rolling bearing rotational axis direction and a second-side detection member on the other side in said direction, and a measurement unit (16) for outputting measurement information obtained by measuring the electrical properties between the first-side detection member and the second-side detection member, wherein the first-side and second-side detection members contact the cage when the cage encounters friction.
