摘　　要：本文以齿根应力作为齿轮结构设计的应力约束条件,对齿轮的腹板结构进行了优化设计,在满足齿根最大等效应力的情况下,齿轮的整体重量减少了27.39%,大大节约了材料,降低了成本。这种将有限元技术应用到优化设计中的方法,真正意义上实现了零部件的计算机辅助设计,是实现零部件设计自动化的主要途径。The paper used stress of root of tooth that was resolved as stress constraint condition, and carried out optimum design in the web plate structure. The whole gear＇s weight reduced to 27.39% under the condition of less than the most equivalent stress of the root of tooth. It gTeatly saves material and reduces cost. The method that applying finite element technology to optimum design achieves computer aided design （CAD） of parts indeed, and it is the main approach of achieving automatic design of parts.
