COMBINED RADIAL-AXIAL GAS-DYNAMIC LEAF-TYPE PLAIN BEARING Russian patent published in 2013 - IPC F16C17/10 F16C27/02 F16C32/06 

FIELD: machine building.

SUBSTANCE: invention can be used as supports of high-speed rotors of machines and units loaded with radial and axial loads, provide when required high carrying capacity at preserving stable position of the rotor in air conditioning systems of aircraft cabins, as well as turbo-supercharge systems in modern car industry and in microgas-turbine electric units. A combined radial-axial gas-dynamic leaf-type plain bearing includes a sleeve enclosing the shaft neck with slots located on its inner surface, into which inserts with leaves are inserted. In order to provide higher carrying capacity at maintaining the rotor stability in the design there provided is cylindrical and conical surfaces of the bearing and the shaft.

EFFECT: improving reliability and increasing durability of a bearing assembly, service life, stable movement and suppression of beating of shafts and rotors.
