The design of worm drive usually uses the method of intensity emendation, the design is fit for the condition of design, but it' s not the most optimized. With the three-dimension software Pro/e as a design platform, the interface was designed by software VC ++ 6.0, the three-dimension models was created by the dimension-drive and program-drive function of the software Pro/e. By inputting the design information, the calculation for optimized design was carried out by software Matlab7. 0, the three-dimension model of the worm and worm wheel a...
