Beschreibung
Zusammenfassung:	mechanical engineering; gas-turbine engines. SUBSTANCE: proposed sealing device has labyrinth with hub connected by splines with compressor shaft. Plate of hub consists of two sections differing in thickness. Bulge is found between sections in hub plate. Radius of bottom of hub spline spaces is 0.45 - 0.5 of space width. EFFECT: increased reliability of sealing device by reduction of level of stresses in labyrinth hub. 3 dwg
