In gears with eccentric errors, the tooth-meshing frequency is subjected to both amplitude modulation and frequency modulation at the same time. Consequently, the noise spectrums consist of a large number of sidebands. The general equation about sideband levels is derived in the case the modulation signals include the high order harmonics of the angular frequency of the eccentric gear. The value of the parameter inthe general equation is estimated from the change of the amplitude of the tooth-meshing noise and the fluctuation of the angular velocity of the input and the output shaft. The appropriateness of the general equation is shown by comparing the spectrum of the actual tooth-meshing noise with the calculated one by the general equation.
