摘　　要：TI蜗杆传动的实体造型由渐开线斜齿轮和它所包络的TI蜗杆的三维造型两部分组成。本文以造型软件PRO/E为工具,完成了TI蜗杆传动中蜗轮(斜齿轮)的精确三维造型,采用间接造型的方法实现了TI蜗杆的三维建模。利用接触线方程进行数值分析,在蜗杆三维模型上绘制出齿面接触线,直观地展示了TI蜗杆传动齿面接触线的形成过程。显示了三维造型技术在蜗杆传动研究领域应用中的重要性。Solid modeling of TI worm gear drive is composed of two parts,3Dmodeling of involute helical gear and hourglass worm enveloped by the gear.Base on the modeling soft of PRO/E,the methods of accurate modeling for gear and indirect modeling for TI worm are described.Accurate models offer the foundation for further studying TI worm gear drive performance.Using the result of numerical value analysis,contact lines are drawn on 3d model,which straightly confirm the theoretical analysis results and indicate the importance of 3d modeling.
