本发明的铁道车辆的轴承监视装置,监视支持车体的转向架的轴承,具备:信号接收器,接收轴承温度的数据、与该轴承的负载及旋转速度中的至少一方的数据;及诊断器,在监视值超过可变阈值的情形时,判定为在该轴承产生异常,该监视值是自该信号接收器所接收的轴承温度的数据获得的温度值及温度上升率的至少一方;该诊断器,在该负载及该旋转速度中的至少一方的数据的值减少时,降低该可变阈值。
Provided is a bearing monitoring device of a railcar, the bearing monitoring device being configured to monitor a bearing of a bogie supporting a carbody, the bearing monitoring device including: a receiving unit configured to receive a data piece of a temperature of the bearing and at least one of a data piece of a load of the bearing and a data piece of a rotating speed of the bearing; and a diagnostic unit configured to, when a monitoring value exceeds a variable threshold, determine that an abnormality of the bearing has occurred, the monitoring value being at least one of a temperature value and a temperature increase rate, the at least one of the temperature value and the temperature increase rate being obtained from the data piece of the temperature of the bearing received by the receiving unit, wherein when at least one of a value of the data piece of the load and a value of the data piece of the rotating speed decreases, the diagnostic unit lowers the variable threshold.
