GAS-TURBINE PLANT Russian patent published in 2001 - IPC

FIELD: mechanical engineering. SUBSTANCE: proposed gas- turbine plant has intake device and power turbine with radial-thrust bearing. Bearing is installed at side of intake device. Unloading space is located before bearing. Unloading space is formed by labyrinth disk secured on shaft and stator flange of labyrinth seal. Invention improves reliability of plant owing to increasing service life of bearing and stability of power turbine rotor shaft by compensation of axial forces acting onto bearing, arrangement of bearing out of zone of action of hot gases and exclusion of compressing forces acting onto power turbine shaft. Shaft. EFFECT: improved reliability of operation. 3 dwg
