Abstract

659,592. Turbine and compressor rotors. SULZER FRERES SOC. ANON. Aug. 2, 1949, No. 20111. Convention date, Sept. 17, 1948. [Class 110(iii)] In a rotor for a turbine or an axial flow com, pressor in which blades are in. serted into circumferential grooves through a filling aperture, the aperture is closed by means of a mul. ti-part key, the main part of which is wedgeshaped and tapers outwardly and means are provided for urging this mair part outwardly In Fig. 3, the filling aperture 3 has overhang ing shoulders and the main part 6 of the key is threaded to receive a screw 7. The two auxiliary parts 9 of the key are also wedge-shaped. The screw 7 bears against a spring disc 16 in a recess in the filling aperture and the parts 9 have extensions 13 against which the head of the screw 7 may bear to assist in dismantling. A slit 15 is provided in the main part 6 whereby the screw 7 is locked by the wedging action. The filling aperture may be of inverted T-section or of staggered wedge section and the auxiliary parts are correspondingly shaped. In Fig. 6 the root 30 of a blade is wedge-shaped and forms one part of the key, an auxiliary wedge-shaped piece 37 being inserted between the root and the main part 38 of the key.
