毕业设计（论文）-基于Proe的齿轮加工设计仿真精选.doc

摘 要 Pro/Enginer是美国PTC公司的产品，于1988年问世Pro/Enginer is America PTC products, came out in 1988. Born in ten years, has experienced 20 times of revision, become the standard software 3D CAD/CAM system in the world and Chinas most popular. Widely used in electronics, machinery, tooling, industrial design, automotive, aerospace and other industries, toy, add. It is the all directions 3D product development software package. A collection of parts design, product assembly, mold development, manufacturing, sheet metal parts design, industrial design, reverse engineering, automatic measurement, mechanism analysis, database management and other functions. In order to shorten product development time and simplify the development process. Gear is an important part of industrial production. In the gear production process, Pro/E also plays an important role. In the gear industry, due to the special nature of the gear itself, the parameter is widely used. Parameterization is based on mathematical method, the geometric constraint is based on artificial intelligence method, based on the principle of geometric modeling method of feature model. The gear parametric modeling is mainly used in the modeling of components in industrial production. The purpose is to design method and structure characteristics of more in-depth study of gear and the worm, worm. Graduation design is an important part of the subject, is the detection of common learning, common practice is irreplaceable teaching life.
