Granitsy primenimosti i ekonomicheskiy effekt ot vnedreniya gibridnykh gazovykh podshipnikov

The bearings on gasfilm lubrication system such as gasstatic air bearings are widely known; to create a lifting force they use an air forced supply into a bearing gap under excess pressure. Gas dynamic bearings that create a lifting force only at sufficiently high speed of a shaft rotation due to the Poiseuille aerodynamic effect are also widespread. Hybrid bearings may operate both in gasdynamic and gasstatic regimes. The work examines the limits of such parameters as bearing capacity, typical geometrical sizes and precision of their manufacture that define the rationality of using gasstatic, gasdynamic and hybrid air bearings; the economic effect of implementation of such bearings, in particular, in turbomachines, was estimated as well.
