本文介绍了高参数航空涡轮制冷机用高速气体轴承研制中的部分工作。在论述工作环境条件苛刻的这类制冷机中用气体轴承替代滚动轴承的必要性、可行性和特殊性的基础上,叙述了研制这类气体轴承时在设计、选材、加工和调试等方面完成的多项特殊试验以及气体轴承改装产品的航空环境适应性试验和应用概况。 This paper describes some of the work in the development of high-speed gas bearings for high-parameter aviation turbine refrigerators. Based on the necessity, feasibility and particularity of using gas bearings instead of rolling bearings in the refrigerators with harsh operating conditions, this paper describes the design, material selection, machining and debugging of such gas bearings A number of special tests as well as gas bearing modified products aviation environment adaptability test and application overview.
