Description
上記課題を解決するために本発明のセンサ付き転がり軸受装置は、軸の周方向に沿って磁界が交互に変化するように取り付けられた磁性体と、その磁性体の回転速度を計測するように非回転輪側に固定されたセンサとを有するセンサ付き転がり軸受装置であって、前記センサは前記軸受装置の非回転輪を固定する固定部材に固定され、前記軸の外周面に嵌合して固定された環状部材を備え、前記環状部材は、前記軸受装置の回転輪と非回転輪との間の空間を軸方向から覆う鍔部を備え、前記磁性体は前記鍔部の前記軸受に対向する面に周方向に渡って固定され、前記センサは、前記磁性体と前記軸受との間に位置し、前記磁性体は前記環状部材に固定されたことを特徴とする。 In order to solve the above problems, the sensor-equipped rolling bearing device according to the present invention measures a rotational speed of a magnetic body attached so that a magnetic field changes alternately along the circumferential direction of the shaft, and the rotational speed of the magnetic body. A sensor-equipped rolling bearing device having a sensor fixed on a non-rotating wheel side, wherein the sensor is fixed to a fixing member that fixes the non-rotating wheel of the bearing device, and is fitted to an outer peripheral surface of the shaft. A fixed annular member, and the annular member includes a flange portion that covers the space between the rotating wheel and the non-rotating wheel of the bearing device from the axial direction, and the magnetic body faces the bearing of the flange portion. The sensor is positioned between the magnetic body and the bearing, and the magnetic body is fixed to the annular member.
