摘　　要：推导了渐开线曲线的参数方程,基于Pro/E5.0对渐开线花键进行了参数化造型并使用Pro/toolkit对Pro/E进行二次开发,得到了渐开线花键参数化造型模板零件,可快速修改参数并再生出新的花键;提出了一种滚轧花键坯料直径数值计算方法,并对DIN5480标准中不同规格的花键进行了滚轧坯料直径计算,得到的结果可为滚轧工艺数值模拟提供依据。The parametric equation of the involute curve has been deduced. The parametric model has been estab- lished to the involute spline based on Pro/E 5.0. The second development has been conducted to Pro/E by use of Pro/toolkit. Theinvolute spline parametric modeling template parts have been gained, which can quickly modify pa- rameters and regenerate new spline. Anumerical method to calculate the rolling spline billet diameter has been put forward, and different specifications of the spline rolling billet diameter in DIN5480 standard have been calculat- ed. The results can provide a basis for numerical simulation of rolling process.
