SUPPORT OF GAS TURBINE ENGINE Russian patent published in 2002 - IPC

FIELD: mechanical engineering; gas turbine engines. SUBSTANCE: support is designed for gas turbine engines, including those of ground application. It improves reliability of operation of gas turbine engine by excluding getting of oil particles into engine gas-air duct. Support has bearing secured on engine housing and oil space around bearing. Labyrinth seal separating oil space of support from air space of engine is provided with intermediate air-oil space connected at inlet through slot with oil space and through labyrinth seal, with air space, and at outlet, through channel in lower part of stator flange of labyrinth seal, with oil space. Intermediate air-oil space is formed by U-shaped projection of stator flange, conical lip of projection is made at acute angle to support axis forming radial overlap of Δ = 0...10 mm, with first rib of labyrinth relative to bearing. First rib is mirror part relative to other ribs of labyrinth. EFFECT: increased reliability of operation of support by excluding penetration of oil particles into gas-duct of engine. 2 dwg
