Abstract

1,236,920. Rotor blade fixing. ROLLSROYCE Ltd. July 15, 1968 [July 13, 1967], No. 32190/67. Heading F1T. The blades 14 in at least one rotor blade row of a fluid-flow machine, e.g. the compressor of a gas turbine engine, are mounted in axial slots 12 in the periphery of the rotor body 10 and retained axially in position by ring segments 15 seated in a circumferential groove 16 and slidable in the groove between a first position, Fig.2 (not shown), in which the ends 18 of the segments are spaced apart to permit removal or insertion of a blade and a second position, Fig. 3, in which the segments cover all the slots to retain the blades therein, means being provided to retain the segments in the second position. The segments 15 each cover just under half a circle so that the gap between their ends 18 in the first position will only allow one blade to pass therethrough. In the case of blade row A, the segments 15 are locked in the second position by the heads 20A of screws 20 screwed into a flange 19 to project into the gaps between the ends of the segments. Whereas for rows B and C the segments are locked by projections 23 from the end flanges on cylindrical spacer rings 24. The latter carry sealing ribs 31 and are located against circumferential movement and outward bowing by engagement of lugs 25 on the rings in axial slots 26 provided in projections 27 on the rotor body 10. The assembly sequence of the blades and spacer rings is described. The number of blades in each row may differ to reduce vibration. In a modification, the rotor body is constructed of separate discs releasably secured together.
