CONIC LEAF-TYPE FRICTION BEARING Russian patent published in 2011 - IPC F16C17/12 F16C27/02 F16C32/06 

FIELD: machine building.

SUBSTANCE: conic leaf-type friction bearing consists of bush enveloping journal of shaft. On internal surface of the bush there are made slots wherein there are inserted leafs. The leaves are protected from falling out with end covers screwed to a case of the bearing. In the middle of the bearing there is an amount of radial orifices multiple to the amount of leaves for supply of gas under pressure and for facilitation of additional gas-static pressure in a working area.

EFFECT: conic leaf-type friction bearing increases reliability and service life of bearing unit, endurance, stability of motion and suppression of shafts and rotors runout owing to additional gas-static pressure in working area.
