摘　　要：齿轮传动影响因素多,如何设计才能使齿轮结构紧凑、承载能力强是一个值得深入探讨的问题。根据实际工程条件,以齿轮机构体积最小为目标构造目标函数,列取模数、齿宽、应力、结构等为约束条件,建立包含6个设计变量、12个约束条件的圆柱齿轮优化设计数学模型,并将优化结果在UG中运用表达式功能进行了齿轮参数化设计和精确造型。There are many factors that influence gear transmission. Therefore question of how to design a gear with compact structure and high load capacity is worthy of in-depth discussion. Based on practical/realistic engineering conditions. A mathematical cylindrical gear design model is presented which incorporates an objective function of 6 design variables and 12 constraints （modulus, tooth width, stress, structure, etc.） and minimizes structural volume of target gear set. The result of optimization is applied to subsequent parametrical gear design and precision modeling utilizing expression functions of UG.
