Abstract

715,044. Turbine and compressor rotors. ROLLSROYCE, Ltd. July 29, 1952 [Aug. 23, 1951], No. 19952/51. Class 110(3) In a rotor comprising a disc 13a liable to expansion under' centrifugal loads and having at its centre a bore substantially larger than the shaft 10, the disc is formed at its centre with a thin axially-extending sleeve-like extension 16 having at its end remote from the disc a thin re-entrant flange 17b, spaced from the bore and the shaft, and terminating in the plane of the disc in a thickened internally-splined bead 17c making an interference fit with a set of splines on the shaft. The discs are axially spaced by separate spacer rings 14 or by axially directed abutting flanges 15. The disc assembly is placed in compression by a ring nut 27 threaded on the shaft, the degree of compression being determined by the thickness of the washer 29. An extraction rim .17d is provided on each re-entrant flange 17b. The rim can be engaged by a tool to withdraw the disc from the shaft.
