The alignment condition of automotive gears changes considerably during operation due to the deformation of shafts, bearings, and gear box by transmitting load. Under such condition, the gears are requested to satisfy not only reliability in strength and durability under the maximum loading, but also low vibrational characteristics under light loading at cruising of the car. In the previous report, the fundamental method for optimization of 3 dimensional tooth flank form in terms of both vibration and load carrying capacity for such gears was proposed. Gears of high total contact ratio have although multiple local optimum solutions in the design of tooth flank form and it is therefore needed to choose the comprehensively optimum tooth flank form. In this report, the influence of the choice of different local optimum solution in different vibrational excitation valley and the influence of different vibrational criterion at the optimizing procedure on the low vibrational performance of the optimized gears are investigated. The practical design algorithm for the optimum tooth flank form of a gear set in terms of both vibration and load carrying capacity is then proposed and its result is evaluated by the field experience.
