摘要

Hybrid gas bearings could increase its load-carrying capacity and stiffness considerably, especially the high-speed bearings. In 1971 Fleming presented a hybrid gas bearing [1] with double columns orifices and a herringbone grooves and with a disturb method calculated its performance. It is witnessed that this bearing had a weakened performances including load carry capacity and stiffness under a low compressible number. This phenomenon had been explained in 2006 [2, 3] by analytical analysis combined aerostatics and aerodynamics based on Whipple-like theory and the reason is that the structure coupling between aerodynamics and aerostatics weakened the performances. The groove configuration could be changed to overcome this disadvantage. An Out-Pump type aerodynamic/aerostatic thrust bearing [4] has been presented in 2008 considering coupling of aerodynamics and aerostatics with incompressible assumption.
