BEARING DEVICE WITH ABSOLUTE-TYPE ROTATION SENSOR

Japanese Patent JP2023149189

A

To provide a bearing device with an absolute-type rotation sensor which has a double-row track type rotation sensor, and is easy in assembling and transportation.SOLUTION: In a bearing device (1) with an absolute-type rotation sensor having a bearing (3), an annular detected member (5) fixed to a rotating shaft which is supported to the bearing, and having a detected part (19) having two rows of magnetic tracks, a rotation sensor (7) fixed to a fixed-side bearing ring (11) of the bearing (3), and detecting the rotation of the detected part (19) in a non-contact manner, a sensor baseboard (23) mounted with the rotation sensor (7), and a sensor housing (21) attached with the sensor baseboard (23), a screw member (43) which is constituted so as to be capable of advancing and retreating in a direction parallel with an axial core direction of the bearing is arranged at the sensor housing (21) so that the detected member (5) can abut on a rotation-side bearing ring of the bearing, and can be released in the abutment.SELECTED DRAWING: Figure 1
