The main characteristics of it is large power transmission、manufacture simple、easy maintenance and long life. Traditionally, in order to get satisfied design data of reducer, you must cut and try again and again. Although this design can satisfy conditions given. Proved by the practice, according to the traditional design method to the design, most of them have room for improvement, it is not optimal. In this article we will two-grade helical cylindrical gear redactor conduct optimal design . Taking account the minimum distance of center into the goal, penalty function used in this method . In this paper, by the way of selecting design variable , setting up goal function and restriction condition , the mathematical model of cylindrical gear reducer is established . The preparation of the optimal design program , run by the computer and calculating the optimal design parameters . The structure of the gear reducer is analyzed and made conventional design in theory, and some other accessories for the corresponding design , which proved reasonable for the the checking of Tooth surface and tooth root bending strength after the designation completed . The results show that the optimal design methods , strength requirements are met under the premise of the size reducer greatly reduced, reducing the timber and the cost , improve the design efficiency and quality.
