摘要(Abstract)：

气体轴承具有速度高、精度高、功耗低、寿命长、低振动、无污染等优点,气体润滑技术在高速透平机械中具有广泛的开发和应用前景。全面回顾了我国在低温透平膨胀机领域开发应用气体轴承的历史与发展概况,以及国外在制冷机、风机等通用高速透平机械中动压气体轴承成功应用的实例。
Gas lubricated bearings are of tremendous prospect especially in high speed turbo-machinery fields because gas bearings retain some prominent advantages such as high precision,low power loss,long life,low vibration and no contamination etc.The use of gas bearing in cryogenic turbo-expanders in china is summarized.The outline of the application of aerodynamic gas bearing in some foreign countries within several high speed turbo-machineries including refrigeration compressor and blower are presented.
