PROBLEM TO BE SOLVED: To reduce cost and installation work of a device which acquires the temperature of a bearing together with the load and/or the rotational speed thereof to monitor the condition of the bearing.SOLUTION: There is provided a bearing monitoring device for a railroad vehicle in which a plurality of vehicles each having a vehicle body and trucks are joined to each other. The bearing monitoring device comprises: a bearing temperature sensor provided in each of the trucks and directly or indirectly detecting the temperature of a bearing of each truck; at least one condition sensor provided in at least one of the vehicle bodies of the plurality of vehicles, and used to calculate the load or the rotational speed of the bearing; and a memory provided in at least one of the vehicle bodies of the plurality of vehicles and memorizing each data of each signal detected by the bearing temperature sensor and the condition sensor.SELECTED DRAWING: Figure 1

    【課題】軸受の温度とともに軸受の荷重及び/又は回転速度を取得して軸受の状態を監視する装置において、装置コスト及び設置作業を低減する。【解決手段】車体及び台車を有する複数の車両が互いに連結されてなる鉄道車両の軸受監視装置であって、各前記台車に設けられ、各前記台車の軸受の温度を直接的又は間接的に検出する軸受温度センサと、前記複数の車両の少なくとも1つの前記車体に設けられ、前記軸受の荷重又は回転速度の算出に用いる少なくとも1つの状態センサと、前記複数の車両の少なくとも1つの車体に設けられ、前記軸受温度センサ及び前記状態センサで検出された各信号の各データを記憶する記憶器と、を備える。【選択図】図1
