RESILIENT DAMPING SUPPORT Russian patent published in 1999 - IPC

FIELD: mechanical engineering; supports for gas-turbine engine rotors. SUBSTANCE: jet flange with jets is centered during assembly in radial direction by means of centering projections relative to centering surface in inner spring. flange is axially pressed between outer rate of roller bearing and nut and is circumferentially fixed by means of T-shaped projections of plate over side surfaces of centering projections; this plate is used for keeping the nut from turn after radial tail-piece in nut slots. Plates are mounted as lock on opposite sides from centering projections of jet flange to avoid turning of flange both clockwise and counter-clockwise. During operation of engine, resilient damping support of construction ensures matching of oil passages in jet flange and in flexible members and excludes delay of delivery of oil to bearing which may cause break of bearing. EFFECT: enhanced efficiency and reliability. 4 dwg
