ROLLING BEARING DEVICE WITH SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a rolling bearing device with a sensor in which the sensor can be disposed in a space-saving manner.SOLUTION: A rolling bearing device with a sensor 1 includes: a rolling bearing 10 having an outer ring 11 having an outer ring raceway 11a on an inner peripheral surface, an inner ring 12 having an inner ring raceway 12a confronting the outer ring raceway 11a on an outer peripheral surface and concentrically arranged with the outer ring 11, and a plurality of balls 13 interposed between the outer ring raceway 11a and the inner ring raceway 12a to be freely rolled; and sensors 21 and 22 for detecting a state of the rolling bearing 10. A center line Y1 in the axial direction of the outer ring raceway 11a and the inner ring raceway 12a is shifted to one end side in the axial direction with respect to a center line C1 in the axial direction of the corresponding outer ring 11 and the inner ring 12. Cutout step parts 11b and 12b for forming a storage space 15 for storing the sensors 21 and 22 between the outer ring 11 and the inner ring 12 are formed on the other end side in the axial direction of the inner peripheral surface of the outer ring 11 and the outer peripheral surface of the inner ring 12.SELECTED DRAWING: Figure 1
