Japanese Patent JP2023147973
Kind Code:
A
Abstract:
To provide a bearing device with a sensor capable of reusing at least a sensor unit even when a rolling bearing is exchanged.SOLUTION: A bearing with a sensor is equipped with a bearing that includes a rotary ring, a fixed ring, and a rolling body, and a sensor unit. The rotary ring has a rotary ring raceway surface extending in a circumferential direction. The fixed ring has a fixed ring raceway surface extending in the circumferential direction and opposing the rotary ring raceway surface at an interval in a radial direction. The rolling body is disposed between the rotary ring raceway surface and the fixed ring raceway surface. The sensor unit has a generation coil that is detachably attached to the fixed ring and generates induction electromotive voltage with rotations of the rotary ring, a sensor that outputs physical amount or chemical amount as an electric signal, and a radio communication module that radio-transmits the output of the sensor to the outside.SELECTED DRAWING: Figure 1A
