In view of the characteristics of the low-noise and high-strength of auto gears, this paper proposes a new method of optimization of fine-pitch tooth profile. Based on the constant gear-pair parameter values of transmission ratio, modulus, pressure angle, the method takes the optimal contact ratio as design object, sets up the constraint conditions such as noise limit index, non-interference, non-undercutting, and non-sharpened in the tip, and optimizes the addendum coefficient and coefficient so as to increase the contact ratio. In addition, this paper makes a finite element strength analysis on the design result, and the result shows that the new method can not only reduces noise but also improves gear strength of fine-pitch gear.
