Title:
BEARING DEVICE WITH ABSOLUTE-TYPE ROTATION SENSOR
Document Type and Number:
Japanese Patent JP2022149362
Kind Code:
A
Abstract:
To provide a bearing device with an absolute-type rotation sensor which can simplify a constitution by a small number of part items by combining a double-row track-type rotation sensor to a bearing, and is easy in assembling.SOLUTION: In a bearing device (1) with an absolute-type rotation sensor comprising a bearing (3) and a detected member (5) fixed to a rotation-side bearing ring of the bearing (3), and having a detected part (19) having a double-row magnetic track arranged over a peripheral direction of an annular core grid (17), there is arranged a rotation sensor unit (7) having one rotation sensor (21) fixed to a fixed-side bearing ring of the bearing (3), and detecting the rotation of the detected part (19) at a non-contact manner, a sensor baseboard (23) on which the rotation sensor (21) is mounted, and a sensor housing (25) for covering the sensor baseboard (23), and attached with the sensor baseboard (23).SELECTED DRAWING: Figure 1
