谐波齿轮减速器的设计 摘要：谐波传动是五十年代中期出现的一种新型传动，它随着空间技术的发展而迅速发展起来。由于谐波传动具有传动比大、体积孝传动精度高的特点，一开始就被运用在火箭、导弹、卫星等飞行器中，实现了他的优越性。目前这种传动技术已由航天飞行器，飞机中的应用迅速推广到原子能、雷达、通讯、造船、冶金、汽车、坦克、机床、仪表、防止、建筑、起重运输、医疗器械等各个部门。无论是作为数据传递的高精度传动，还是作为传递大转矩的动力传动，都得到了比较满意的效果。特别是，这种传动通过密封壁来传递机械运动，因而它用于操纵高温，高压的管路以及用来驱动工作在高真空，有原子辐射或其他有害介质空间的机构，是现有的其他一切传动所不能比拟的。 关键词：谐波传动，齿轮，减速器 The Desig
