Title:
BEARING WITH SENSOR
Document Type and Number:
WIPO Patent Application WO/2024/058050
Kind Code:
A1
Abstract:
The objective of the present invention is to make it possible to avoid contraction of an inner diameter surface of an inner race of a rolling bearing even if a magnetic ring of a magnetic rotation sensor is coupled to an outer circumferential portion of the inner race, and to improve the reusability of the magnetic ring when replacing the inner race, while enabling the outer circumferential portion of the inner race to be coupled to the magnetic ring even if the width of the inner race is small. In order to achieve this objective, a hook member (20) formed in an annular shape using a resin is provided. An outer circumferential groove (12a) extending in a circumferential direction is formed in an outer circumferential portion (12) of an inner race (3). The hook member (20) includes a protruding portion (25) that is engaged with the outer circumferential groove (12a) of the inner race (3). A metal core (18) is retained by the hook member (20).
