It is a foundation of engineering design to optimize technology most. Because of the popularization and application of the technology of the computer and improvement of operation ability, optimization design based on computer make the solving in complicated system optimum has obvious advantages, and promoting the wide application in engineering design of optimization design. The general steps of optimization design are following: 1.Setting up systematic mathematics model, generally speaking, the model makes up by the the equation of balance, engineering design relational expression and equation of the physical phenomenon in the system describing the physical characteristic. The model describes the interreaction among every variable and designing the impact on systematic function standard of the variable, confirming the goal function of the model; 2.Finding out the systematic restraint condition , namely some of above-mentioned equations supplements the inequality, with since confirm by range of allowing, not most performance not minimum not heavy ; 3.Working out the most optimum design value. It is through being minimum in this text drive than, modulus, tooth count and setting up terms of restraining, utilizing Powells method to draw the best result finally.Keyword: Main transmission Optimization design I
