ABSTRACT:Pro/E depend on its strong modeling function, the parameters of style design, and the characteristics of the unified database management, let it become machine manufacturing industry at home and abroad and most widely used one of CAD/CAM software. PTC software included in the series of industrial design and mechanical design, and other aspects of the multiple functions, which also include large assembly body of the management, the function, the simulation, the manufacture, the product data management and so on. Pro/E also provides a comprehensive, integrated closely product development environment. is a set of the design to production machinery automation software, is a new generation of product modeling system, is a set of parameterized, based on the characteristics of the solid modeling system, and has the function of a single database comprehensive MCAD software, Pro/E software in parts of the three-dimensional entity reducer modeling and virtual assembly has important application in. the traditional design of gear reducer inefficient and easy to make a mistake. And reducer parametric design is to improve the design efficiency and precision of the effective way. In understanding the development situation and reducer parametric design based on the research progress, make gear reducer modeling and simulation movement parts of the overall scheme, the use of the Pro/E modeling functions, building up a 3 d model of gear reducer, finally application of Pro/E motion simulation function, make speed reducer design direct-viewing, fast and efficient, this technology in mechanical engineering, chemical equipment, automobile manufacturing, and many are in the areas of strong practicability and popularize value.
