Web13 de abr. de 2004 · This is the net rotor load capacity for a matched pair of opposing hydrodynamic thrust bearings. - "A self-acting gas thrust bearing for high-speed microrotors" ... The micro hybrid spiral-grooved thrust bearing is a promising candidate to support the rotating elements in power MEMS devices such as micro gas turbine engines. WebThe non-linear dynamic behavior of a hybrid air bearing-rotor system is very complicated and requires careful attention when designing to avoid spindle failure, especially under ultra-high speed condition. In this paper, the rotor trajectory of a hybrid air bearing-rotor system is obtained by solving the unsteady Reynolds equation and motion equations simultaneously.
