摘要 谐波齿轮传动是20世纪50年代发展起来的一种靠柔性齿轮原理来传动的新的传动型式。我国从60年代初开始研制，主要是在科研机构与高校进行，多年来得到了很大的发展。它具有体积小、重量轻、传动比大、精度高等特点，目前被广泛应用在航空航天、仪器仪表、机器人、雷达等需要精密定位的领域。不同于一般的齿轮传动，谐波齿轮传动的扭转刚度具有明显的非线性特性。目前，我们需要研发一种小体积、长寿命、高承载能力谐波齿轮减速器，对传动装置的可靠性、重量、体积、回差、扭转刚度及动态性能等均提出了很高要求。我国现有的杯形柔轮谐波齿轮传动装置，轴向尺寸大，不能满足安装空间的要求；现有的短筒杯形柔轮谐波齿轮传动装置，虽然轴向尺寸较小，但不可避免地带来了应力急剧增加的问题，导致其承载能力不高；因有柔性轴承的存在，导致其成本高和寿命短。 本设计根据谐波齿轮传动的基本理论，建立谐波齿轮减速器虚拟样机模型；对谐波齿轮关键零部件进行强度校核。通过本课题可以了解谐波齿轮传动的更多特点，更多地去研究和创新。 关键词：谐波齿轮减速器，双波发生器，柔轮，钢轮，传动装置 Abstract Harmo
