FIELD: engines and pumps.
SUBSTANCE: invention is related to devices for lubrication of gas-turbine engine bearings and may be applied in most stressed supports of turbomachines rotors. Catching hole of visor arranged as integral with oil catching ring, is coupled with receiving socket provided on rotor journal, recesses are provided on internal surface of oil catching ring, which connect receiving sockets with collecting cavity, besides, oil supply channels are arranged on mounting surface of shaft for bearing internal ring, and these channels connect collecting and flow cavity. Recesses on internal surface of oil catcher ring have conical surface. Mutual position of receiving socket located on rotor journal, catcher hole and local recess on oil catcher ring is fixed by means of pin.
EFFECT: improvement of device for oil supply to holes at the ends of bearing internal ring half-races, when oil bath is not available on journal internal surface.
