LEAF-TYPE GAS BEARING WITH SUPERCHARGE Russian patent published in 2009 - IPC F16C27/02 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering, particularly to bearings with gas-film lubrication, used for suspension of shafts, rotors, rotating casings of different mechanisms, allowing complex loading nature of bearing elements, including torque transfer, axial and radial load, load from sinusoidal vibrations of rotating parts. Leaf-type gas bearing with supercharge includes mobile card, installed on mobile element of mechanism, and immovable card, installed on immovable element of mechanism, with fixed on it reference elements, and overlapping each other by elastic leaves. Each of leaves is fixed by one end on reference element, and by other end is beard on mobile card. On mobile card from both sides there are implemented butt forcing devices with blades and inner inducer with blades, channels for feeding of working gas to blades.

EFFECT: optimisation of rigidity and load-carrying ability of bearing mount assembly by means of receiving of the least rate of angular motion of mobile card, at which it set in of mode of neatly aerodynamical friction, that is separation of elastically deformed leaves of mobile card by lubricating layer of working gas.
