A multiple objective function optimization design of straight bevel gearing with an advanced optimization method is described. The main parameters and geometric dimensions obtained with this algorithm are made use of to make computer parametric drawing of bevel gear in accordance with gear structure and by adopting currently high-level FORAUT interface software and the U. S.-made AUTOCAD autoplotting package, thus organically combining mechanical design calculation with the drawing of graphs.

The said program is applicable to the optimization design of straight bevel gearing with arbitrary shaft angles and different pressure angles (α = 14.5°, 20°, 22.5°, 25°) to obtain ideal optimization parameters or engagement parameters, geometrical parameters and strength performance parameters and plot the correspnnding part working diagram.

The results of application show that the system proposed is feasible, the algorithm explicit, the program operation reliable, convenient and flexible.
