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。

The DesignofHarmonicGear Reducer
Abstract:Harmonic Drive is a newly established drive firstly appeared in the mid 1950s,with the rapid development space technology. With the attributes of high drive ratio, smallvolume and high transmission accuracy, harmonic drivewas largely applied in aerocrafts such as rocket, missile and satellite. Nowadays, this drive technology has already been expanded from aerocraft tovarious aspects such as atomic energy, radar, communication, metallurgy, automobile, tank, machine tool, meter, architecture, medical mechanics and so on. No matterworking as high-precision drive transmitting statistics, or as power transmission transmitting high torque, harmonic drive received satisfactory outcomes. This drive use sealed chamber to transmit mechanical movement, so that it has great merits over other driveswhen it is ustilized in controlling pipelineswith high pressure and temperature, aswell as driving mechanisms functioning in space environmentwhich is highvacuum, andwith atomic radiation and harmful media.
