To detect a damage of the gear is strongly requested for the reliable operation of transmission systems. Although many methods based on the vibration analysis of the gearbox were proposed, it remained the limitation in the detection of the location and the size of the damage. In this paper, we developed the method based on the estimation of the rotational speed of the gear to detect the location and the size of wear of the tooth of the gear. Our experimental result showed the good performances in precise estimation of tooth wear.
