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。
Spatial mechanical lubrication is different from the ground equipment, the spaceborne antenna pointing mechanism has its own characteristics, the antenna should be directed to different components of the work mechanism to choose the most suitable lubrication. In this paper, the mechanism, advantages and disadvantages of several lubrication methods commonly used in space machinery are reviewed. The problems that should be considered in the lubrication design of the antenna pointing mechanism and the lubrication measures that can be taken by different components are pointed out.
