中文摘要：

针对硬齿面内齿轮渗碳淬火后难于实现磨削的现状，提出以易于成形磨削的直线齿廓代替渐开线齿廓的方法。建立行星轮系齿轮的几何模型，利用齿面接触分析技术、承载接触分析技术和行星轮相位差的概念计算行星轮系传动误差。在不同转速和载荷下对渐开线内齿轮行星减速器和直廓内齿轮行星减速器进行噪声对比试验。传动误差计算和噪声试验均表明，在一定载荷条件下，直廓内齿轮行星轮系代替渐开线内齿轮行星轮系在工业上是完全可行的。

英文摘要：

In order to improve the accuracy of internal gears with hard face which is hard to grind after quench carburizing process, a new tooth profile with the straight substitute for the involute one was now presented. The geometric models of planetary gear trains were established, so that the TE of planetary gear trains was calculated by TCA and the Loaded Tooth Contact Analysis（LTCA） as well as the concept of planet gears phase. The contrastive experiments of the noise produced from both the planetary gear trains with the straight tooth profile internal gear and with the involute one were carried out. The TE calculations and experiments demonstrate that the transmission error between the straight profile and the involute one is very close under loading conditions, so the straight tooth profile internal gear is fully applicable in the industrial production.
