摘要：提出在SolidWorks中以直角坐标系渐开线参数方程绘制渐开线的两种方法，以德国标准 DIN5480渐开线花键为例，阐述渐开线花键轴的建模。该方法对非标准渐开线齿轮的建模有一定的参考价值。

Abstract: In this paper, two methods for drawing the involute according to the involute parameter equation in the rectangular coordinate system of Solidworks were proposed. The modeling of spline shaft with involute was illustrated by taking the German standard DIN5480 involute spline as an example. It has certain referential value for the modeling of non-standard involute gear.

渐开线花键具有齿根强度高、承载能力强、定心精度高等特点⑴，被广泛应用于机械传动中。随着国外先进技术的引进，不少领域采用了德国标准DIN5480的渐开线花键。图1 所示为塑料机械上配瑞典油马达的过渡联接轴，它采用DIN5480渐开线花键联接，当前流行的三维设计软件中没有提供直接生成渐开线花键特征的功能，目前通常采用两种方法实现渐开线齿廓的建模：一是以软件提供的二次开发接口来完成囚，二是采用GearTrax插件和 SolidWorks软件共同完成建模叫这两种方法均有一定的局限性，本文借助于渐开线的参数方程在SolidWorks中完成该DIN5480渐开线花键的三维建模。
