摘要

大型光学仪器的机械传动系统

对于仪器的瞄准跟踪性能具有很重要的作用。过去这类仪器大都采用蜗杆传动和齿轮传动。考虑到谐波齿轮传动具有速比大、结构紧凑和多齿啮合等特点

研究探讨了在大型精密光学仪器中应用这类新型传动的可能性。试验表明

为负载转动惯量J=200kg·m·s

的俯仰轴研制的大速比谐波齿轮传动的动态传动误差可达9″以内

间隙虚动3″左右。对于转动惯量更大的方位轴

设计试制的谐波齿轮减速器与摩擦滚轮组合成的传动系统

能够获得高精度。文内还对比了两种结构的波发生器

对方位谐波齿轮减速器啮合性能的影响。

Abstract

In large optical instruments

there are always applications of precision worm-wormgear or gears for transmission of azimuth axis and elevation axis. Low efficiency and low wear resistance are the chief disadvantages of the former

although the latter verifies some improvement in transmisslon

but the fabrication cost is rather high. In consideration of the advantages of harmonic gear drive

we have approached to use this new transmission in a large optical instrument. It has been shown that this transmission system has advantages of good structure character

high accuracy and low backlash. Some experimental results from our research work also will be illustrated in this paper.
