This paper deals with a diagnosis of tooth surface failure by change in dynamic performance of a gear using the wavelet transform. The dynamic performances of the gear, which are tooth root strain and vibration acceleration of gear box, were mearsured during the fatigue process of the gear using a power circulating type gear testing machime. These dynamic performances were analyzed at a time-frequency domain using the wavelet transform. As the result of the time-frequency analysis of the vibration, it became clear that each failed tooth can be detected by this analysis when one tooth was failed. However, in the case of adjoining plural failed teeth, it was difficult to detect the all failed teeth. The result of the time- frequency analysis of the tooth root strain suggested that it is possible to detect the failed location on the tooth surface by this analysis.
