螺旋渐开线齿轮传动研究

摘要

In this paper, a new gear transmission with spiral involute is proposed, which works just on point-contact of spiral involutes. Due to uniform speed transmission, this kind gear can be used in transmission between intersecting axes, so that generating milling and generating grinding can be achieved. The generation of tooth profile is introduced in detail. The manufacturing methods and determining parameters of gear is provided. In order to verify the spiral involute gear with constant transmissions ratio, kinematics simulation is implemented in ADAMS based on solid models of a pair of spiral involute gear. The calculated results show that this kind gear can achieve a constant transmission ratio.%基于螺旋渐开线的啮合提出了一种新型齿轮一螺旋渐开线齿轮，这种齿轮就是以螺旋渐开线的点啮合实现传动的，用于相交轴传动，具有简单、易懂的匀速传动原理，可实现展成铣削加工和展成磨削加工。本文中详细阐述了这种新型齿轮的齿廓生成方法，并给出了各基本参数的确定原则，可行的加工方法。建立了一对螺旋渐开线齿轮的实体模型，将这对齿轮模型导入多体动力学分析软件ADAMS中，仿真、计算结果表明：这种螺旋渐开线齿轮可实现定传动比传动。
