Abstract

778,300. Turbine and compressor rotors. ROLLS-ROYCE, Ltd. Aug. 19, 1955 [Aug. 19, 1954], No. 24231/54. Class 110 (3). [Also in Group XXIV] An axial-flow turbine or compressor rotor disc 10 is mounted on a shaft 11 by a thin cylindrical flange 13 secured to the larger end 16 of a rigid frusto-conical member 18 secured to the shaft 11, and by a disc-like member 24 in contact with the shaft 11 and the rotor disc 10, the disc 24 being positioned on the side of the rotor remote from the flange 13 and being adapted to resist deflection of the rotor 10 from a plane at right angles to the shaft axis. The disc 24 is secured to the shaft 11 by the cylindrical portion 19 of the member 18, and has at its outer periphery a thickened portion 27 containing a circumferential groove 29. T- headed members 32 are clamped at spaced positions round the groove 29 by bolts 36 in clearance holes 30, which members have circular sections 34 co-operating with slightly wider slots 31 in a flange 26 on the rotor 10. A spigot 28 has a slight clearance with the inner periphery of the portion 27 of disc 24 to limit tilting deflection of the rotor 10 which is allowed to expand radially by virtue of the thinness of the flange 13. In another embodiment described in the Provisional Specification, the disc-like member is in splined engagement with an extension of the shaft and with a flange on the turbine disc and means are provided to prevent axial displacement of the member in relation to the turbine disc.
