It is necessary to create appropriate configuration and geometry at upstream design stage to satisfy design specifications at detail design stage. In our study, a design system is developed for generating gear trains under design constraints on specified area. The design specifications are input torque, output torque, rotation speed, rotation direction and design space constraints. The spur gear train mechanism is generated based on the generation of random numbers with probability distribution. And then positions of the gear axis are optimized by using the conjugate gradient method. The advantage of the configuration constraints to generating effective gear trains is reported through several examples.
