Beschreibung
Zusammenfassung:	A state monitoring system for monitoring state of a gear device having a plurality of gear pairs has a meshing frequency determination device. The meshing frequency determination device includes a maximum-peak-amplitude calculation unit that calculates a maximum peak amplitude from a detected meshing vibration, in estimated frequency ranges and a set harmonic region, and selects such estimated frequencies that a difference in maximum peak amplitude between a plurality of estimated frequency ranges, is less than or equal to a predetermined multiple, and a meshing frequency determination unit that determines an estimated frequency having a total value of maximum peak amplitudes calculated in the plurality of estimated frequency ranges, within a predetermined time, being the k-th (k is a natural number) greatest among the selected estimated frequencies, as a meshing frequency of a gear pair having the k-th highest tooth surface speed.
