The vibration and noise of gears is due to the vibrational exciting force caused by the tooth stiffness which changes periodically as the mesh of teeth proceeds and by the transmission error, that is, the rotation delay between driving gear and driven gear caused by manufacturing error and alignment error in assembly and so on. The vibrational exciting force between ring gear and planet gear is smaller than that between sun gear and planet gear in the planetary gear train with the thin-rimmed gear. The purpose of this study is to develop how to calculate the optimum amounts of tooth profile modification, by minimizing the vibrational exciting force of sun-planet gears. The proposed method can calculate the optimum amounts of tooth profile modification automatically and is to be utilized to resolve the problem of vibration of planetary gear tarin.<br/>
