The vibration/noise of power transmission gears is one of the serious problems for vehicles, e.g. automobiles, and therefore many researches on gear vibration have been reported. Those reports were, however, concluded by the investigation using numerical simulation which needs input data such as gear dimensions and tooth flank modification. Therefore, the characteristics of transmission error of gears are not clarified theoretically. In the previous report, general model of tooth mesh of gears has been proposed, where quasiinfinite elastic model composed by springs with stiffness peculiar to gears is incorporated and transmission error of gears has been expressed by theoretical equations. In this report, the influence of tooth flank form deviation on transmission error is investigated by general model. It is clarified that form of ridge curve of tooth flank form deviation has much influence on the actual contact ratio corresponding to the minimum amplitude of transmission error. The amplitude of transmission error at peak positions is affected by form of ridge curve and that of curve on contact line.
