Abstract
880,281. Axial-flow compressors and turbines. SULZER FRERES S.A. Aug. 8, 1960 [Aug. 14, 1959], No. 27471/60. Classes 110 (1) and 110 (3). The pivots 5, Fig. 1, of adjustable rotor blades 8 of an axial-flow compressor or turbine are each journalled in a radial bearing 10, and an axial bearing is afforded by a screwthread engagement 3 with a bush 11. The bush 11 is screwed into the rotor hub 1 and, after adjustment to give the required clearance between the blade tips and the casing and to balance the rotor, is secured by a locking device 4. It is stated that the radial displacement of the blades produced by the screw threads 3 when the blades are turned, keeps the mean blade tip clearance substantially constant. In a modification, annular member 6 is omitted and the bearings 10 are formed in hollow extensions of the bushes 11. Fig. 5 shows an inversion of this latter arrangement in which the blades 8 are carried by the extended bushes 11 and the pivots 5 are attached to the hub 1.
