A device for lubrication of bearing of gas-turbine engine includes rotor shaft 1, this has reception hole 15 inner surface of which at tangent line is connected to side surface of opening that catches oil 14, and on the inner surface of oil-catch ring 3 local recess 18 is provided, this has conical surface that connects the opening catching oil 14 to collection cavity 12. Screen 13 of oil-catch ring is arranged as one part with it. On fit surface of rotor shaft 1 for inner ring of bearing 2 oil-supply channels 11 are provided, those connect oil-collection 12 and discharge 10 cavities. A method for assemblage of the device for lubrication of bearing of gas-turbine engine is in connection of opening 14 that catches oil on shaft of rotor 1 and recess 18 on the inner surface of oil-catch ring 3 with pin 1 for provision of respective placement of those at tangent line. Such implementation and assemblage of the device provides oil supply to holes at ends of semi-rings of the inner ring of ball bearing at absence of oil bath on inner surface of shaft and can be used in most loaded supports of shafts of turbo-machines. |
