摘　　要：根据塑性成形前后体积不变原则,应用渐开线基本性质及微积分原理,推导了花键冷滚轧成形前坯料直径计算公式;并通过Pro/E造型验证了花键截面积的数值解,其相对误差小于0.09(,保证了坯料直径的计算精度,为滚轧轮设计提供理论依据。根据理论公式计算的滚压成形前坯料直径制备工件坯料,在工艺实验中获得合格的零件。The diameter of billet before helical involute spline cold rolling has been deduced based on the principal that the former-volume is equal to later-volume in the process of plastic forming by using the property of invo-lute and the knowledge of calculus. The numerical solution of sectional area of spline has been confirmed by Pro/E. The error percentage is less than 0.09 % which insures the calculated accuracy of diameter of billet and affords theory basis for designing model. Acceptable parts are obtained in industrial process according to the theoretical formula of diameter.
