准双曲面齿轮齿面主动设计与先进制造技术

准双曲面齿轮的具面形状对其传动性能起着决定性的作用。现行齿轮设计技术只能在有限的几种模式中被动地选择齿面形式，这限制了齿轮传动性能的进一步提高。齿面主动设计直接以齿面在其全啮合过程中的主要啮合性能参数作为设计变量来确定齿面的形状参数，齿面形式不受传统的摇台结构机床的限制。研究表明，只需用三轴联动CNC铣齿机就能加工出主动设计得到的啮合性能良好的准双曲面齿轮。本文介绍了确定CNC机床参数的原理，提供了直接面向CNC铣齿机的有关的切齿加工计算公式，并给出了计算示例。

A Study on the Function-oriented Design and Advanced Manufacturing Technology for Tooth Surfaces of Hypoid Gears

The tooth surface form has the determinative effect on the performances of a hypoid gear drive. The current design technique for the gears is confined in several types of tooth surface forms, which limits the further enhancement of gear performances. With the function-oriented tooth surface design technique, the parameters of engagement performances were directly taken as design variables to determine the tooth surface parameters, so the tooth surface form is free of limitation by the traditional gear cutting machine. The study shows that the excellent tooth surface obtained by the function-oriented design can be manufactured with the three-axis CNC gear cutting machine. The principle of determining the CNC machine parameters is introduced, the formulae concerned are provided, and a calculating example is presented.
