【Abstract】 Owing to the complex contour of double-linked gear, it is difficult to design a double-linked gear using parameter-driving method. A parameterized design method based on 3D sofeware UG was introduced to conduct 3D modeling. Contour of gear tooth was set up through regulation curve in model module, then 3D model of spur gear was established using UG commands such as Boolean calculation, Pad, Feature ISET Arrays and so forth. A parameterdriving design method was realized that when transforming basic parameter, the corresponding 3D model of double- linked gear is obtained immediately.更多还原
