星载天线指向机构的润滑

Lubrication of the satellite antenna pointing mechanisms

空间机械的润滑不同于地面设备,星载天线指向机构更有其本身的特点,应针对天线指向机构不同组件的工作特点选择最适合的润滑方式。文章对目前空间机械常用的几种润滑方式的机理和优缺点进行了综述,指出了天线指向机构润滑设计应考虑的问题和不同组件可采取的润滑措施。

The lubrication of the space machine is different from the ground equipment, especially used in the Satellite Antenna Pointing Mechanisms （APM）. It＇s essential to select the most appropriate lubricant style for the different components of the APM according to their working features. This paper summarizes the principle and the advantages/disadvantages of the lubricant styles commonly used in current space machine. Some questions that should be considered in the APM and the lubricant measures used in the different components are presented.
