GAS THRUST BEARING OF INCREASED BEARING CAPACITY WITH YIELDING BEARING SURFACE

Advanced Engineering Research, 2010
Basic operation factors of the deformed gas-lubricated thrust bearing with increased bearing capacity are theoretically analysed. It is shown that steady-state operation characteristics of this bearing differ from those of the rigid bearing.
