To remove the vibration from an object other than a bearing for a passenger conveyor and to accurately inspect the degradation of the bearing, when the bearing is inspected.SOLUTION: This inspection device includes: a vibration sensor 11 for detecting a vibration of a bearing 5 of a passenger conveyor; a magnetic sensor 13 for detecting a magnetism generated from the bearing; and a determination processing unit 16 for determining the state of the bearing on the basis of an output signal of the vibration sensor. Here, the determination processing unit 16 extracts a vibration component that is generated by the degradation of the bearing 5 including the rolling element or by the degradation of a shaft 41 of the bearing 5 or a member rotating in interlock with the shaft 41, from the state of an output signal of the vibration sensor 11, in the time of one revolution of the rolling element in the bearing 5 that is calculated from the output signal of the magnetic sensor 13.SELECTED DRAWING: Figure 2
【課題】乗客コンベア用軸受を検査する場合に、軸受以外からの振動を取り除き、正確に軸受の劣化を検査できるようにする。【解決手段】乗客コンベア用軸受5の振動を検出する振動センサ11と、軸受から発生する磁気を検出する磁気センサ13と、振動センサの出力信号を基に軸受の状態を判定する判定処理部16と、を有する。ここで、判定処理部16は、磁気センサ13の出力信号から算出した軸受5内の転動体の1公転の時間における振動センサ11の出力信号の状態から、転動体を含む軸受5の劣化あるいは軸受5の軸41又は軸41と連動して回転する部材の劣化に起因する振動成分を取り出す。【選択図】図2
