Differential characteristics of its structure can be divided into gear, cam, turbo-wheeled freedom and jaw and other forms. The symmetrical design style bevel gear differential, which is mainly composed of the differential housing, planetary gears, axle gears, planetary gear shaft and bolts and other components. The design is mainly for automotive differential design. First, by making the structure and principle of differential analysis, based on the analysis in this structural scheme proposed differential; Next, the main technical parameters were calculated selection; then, for each of the main components were designed and school nuclear; and finally, through the AutoCAD drawing software to draw a differential assembly drawing and major components diagram and by the Pro/E design software to build a three-dimensional model of the differential. Through this design, the consolidation of the university is the professional knowledge, such as: mechanical principles, mechanical design, mechanics of materials, tolerances and interchangeability theory, mechanical drawing and the like; mastered the design of general machinery products and be able to skillfully use AutoCAD mapping software , Pro / E three-dimensional design software, for the future work of great significance in life.
