<p>A bearing damage detection method, comprising: executing frequency analysis for a vibration waveform of the vibration at the bearing obtained through measurement by sensor; setting at least two frequency ranges each substantially equal to a range defined by a rotation frequency fr of the moving ring which do not overlap, based upon results of the frequency analysis; obtaining peak frequencies, each manifesting in one of the plurality of frequency ranges having been set; and determining that the bearing is to be damaged upon deciding that the difference between the peak frequencies and the k multiple of the rotation frequency fr having been compared with each other may be regarded to be matched.</p> |
