ABSTRACT:This design is according to the related theoretical knowledge and standard requirement, using Pro/E related module function to some engineering graphics equipment, such as parts, combination and assembly body of 3D modeling, virtual assembly and movement simulation.Using Pro/E powerful simulation and simulation to promote the reform of teaching, helping students to get a better understanding of the course content, establish specific sensory understanding, it also can faster understand the regular pattern of cartography curriculum, and make a good use about this type of engineering important language. Particularly, Pro/E is based on 3D software engineering graphics teaching method reform, which can bring the abstract of the planar graphics into intuitive and make it easier to understand the 3D graphics, enhancing the mutual transformation between 3D models and 2D drawings, improve the students' space imagination and engineering design ability, reaching the purpose of strengthen the teaching effect about the study of engineering graphics course.

　　　With the help of the powerful Pro/E of cone-cylindrical gear reducer for animation production and movement simulation in this design, Pro/E is mainly using software for 3D entity modeling design to the reducer, animation and virtual assembly generated movement simulation animation, making the product structure and function to the image of the dynamic way to express it, and the whole assembly process is clear. This design mainly covers the cylindrical gear reducer to cone-the removal of parts and surveying and mapping work, 3D modeling the each parts of this design, then the virtual assembly animation production, motion simulation animation. Lastly, virtual assembly animation will introduced the cone-cylindrical gears reduction gear parts structure and assembly process clearly, and the movement simulation animation also show the cone-cylindrical gears reduction gear specific motion clearly, it will improve production efficiency and reduce cost have great significance.
