Title:
MAGNETIC ROTATION SENSOR, BEARING WITH MAGNETIC ROTATION SENSOR, AND METHOD FOR ATTACHING ACTUATOR AND MAGNETIC ROTATION SENSOR
Document Type and Number:
WIPO Patent Application WO/2019/065717
Kind Code:
A1
Abstract:
In the present invention, a sensor holder (12) to be attached to a first lateral surface part (10) of a first member (3) is configured such that a sensor substrate part (16) is fixed to an annular housing part (15) that overlaps in the axial direction with the first lateral surface part (10) of the first member (3). An encoder (13) to be attached to a first lateral surface part (11) of a second member (4) comprises an outward flange part (26) that extends in the lateral direction of the housing part (15) from an annular base part (25) that overlaps in the axial direction with the first lateral surface part (11) of the second member (4) and a magnetic track part (27). When a cylindrical part (33) of a cap (14) is attached to the outer periphery (22) of the housing part (15), an inward flange part (34) of the cap (14) is positioned in the lateral direction from the outward flange part (26), and a labyrinth passage (35) is formed by the cap (14) and encoder (13).
