1. A detecting device comprising:

  • a measuring unit that measures a rotating speed of at least one of connected gears;

    a calculating unit that calculates frequency characteristics for the rotating speed measured by the measuring unit;

    a detecting unit that detects a period of fluctuation of the rotating speed measured by the measuring unit;

    a determining unit that determines whether the connected gears include a damaged gear by using the frequency characteristics calculated by the calculating unit; and

    an identifying unit that, if the determining unit determines that the connected gears include a damaged gear, identifies a gear whose rotation period corresponds to the period detected by the detecting unit as the damaged gear among the connected gears.
