摘　　要：给出了斜航式法向圆弧螺旋锥齿轮的参数化建模方法。推导了在CAD/CAE软件中建立齿轮齿面的方程,解决了建模过程中由于齿面复杂而引起的技术难点。利用ANSYS软件的APDL语言生成齿轮轮廓的主要关键点,结合实体造型功能建立生成齿轮模型的宏文件,完成参数化程序建立。最后,给出了一对齿轮的实体模型以及基于实体模型建立的有限元模型。The parametric modeling method for loxodrome normal circular-arc spiral bevel gear was presented. Equations of profile surface, which can be used in the CAD/CAE software, are developed, and difficulties in modeling due to the complexities of the gear contours were analyzed and solved. The modeling method is applicable to lots of CAD/CAE software, such as ANSYS and UG. The parametric macroinstruction could be made using APDL language, which created the main key points of the gear contour in ANSYS, and the modeling function in ANSYS preprocessor. Finally, the solid models of a pair loxodrome normal circular-arc spiral bevel gear and the finite element models of a pair of single rack are given.
