The design of tooth surface for a low noise under the various load condition is very important. Gear noise is highly related to the transmission error. The optimal tooth surface for the reduction of transmission error is very difficult to determine analytically due to nonlinearity of transmission error and the satisfaction of several load conditions. The satisfaction of design variables in several load conditions leads to Pareto optimum of multi-objective optimization. Therefore, this study proposes the method to determine the optimal lead curve and robust design of the tooth surface, using the response surface method and multi-objective optimization. To do so, the effect of transmission error on candidate design variables by a screening experiment has been investigated using an analysis of variance and the design variables are selected. Then the fitted regression model is built with the statistic validation of the model. The model with constraints is solved to obtain the optimum design of the lead curve and the robust design for the tooth surface.
