摘　　要：针对空间微重力下热泵压缩机的承载与润滑,提出了基于气浮轴承的承载与润滑方案,对气浮轴承的静态特性进行了数值仿真分析,并建立了高速气浮轴承试验系统,获取了高速气浮轴承的静态和动态承载特性。证明了所提出的气浮轴承以氟利昂工质可实现高速稳定运行。The bearing and lubrication technology of heat pump compressor under microgravity envi-ronment was studied and a scheme based on gas thrust bearing was proposed.The static characteris-tics of gas thrust bearings were analysis by numerical simulation.A high speed gas thrust bearing ex-periment system was build,and the static and dynamic characteristics of gas thrust bearings were ob-tained by this experiment system.
