PROBLEM TO BE SOLVED: To provide an abnormality diagnostic apparatus capable of reducing maintenance and management costs by reducing the frequency of disassembly and assembly work, which requires time and labor. SOLUTION: The abnormality diagnostic apparatus for a bearing device for an axle of a rolling stock for diagnosing the presence or absence of abnormalities of the bearing device for the axle of the rolling stock is provided with a detection processing part incorporated in the bering device for outputting a signal, as an electric signal, generated from the bearing deice; an arithmetic processing part for performing arithmetic processing for determining the presence or absence of the abnormalities in machinery facilities on the basis of the output of the detection processing part; a result outputting part for outputting the result of determination by the arithmetic processing part. The detection processing part comprises a vibration detector for detecting vibrations of the bearing device on at least two directions or more. COPYRIGHT: (C)2004,JPO&NCIPI |
