Abstract

745,073. Axial-flow compressors. ROLLSROYCE, Ltd. May 17, 1954 [May 27, 1953], No. 14825/53. Class 110(3) In a rotor for an axial-flow compressor in which the rotor blades are pivotally mounted on the periphery of a disc or drum, a pivot pin for a blade is restrained against displacement axially of itself by a plate member which engages a circumferentially-extending groove on the pivot pin, means being provided to locate the plate member against displacement relative to the disc or drum. A multi-stage axial-flow compressor rotor comprises a number of discs 10, mounted on a common shaft and spaced apart by for instance, flanges 21. The rotor blades 12 are pivoted 'at their roots 14 between annular flanges 11a, 11b by means of pivot pins 15. Plate - members 16 have semi-circular notches 18 which engage annular grooves 17 on the pivot pins 15; each member 16 co-operates with, say, five or, as shown, three pivot 'pins 15. Each plate member 16 engages 'at its outer periphery in a channel 22 and is restrained against circumferential displacement by the engagement of bent lugs 23 with notches formed in an annular rib 25, and against radial displacement by a springy tongue 24 of less thickness than the remainder of the member 16 and having a rib 27 which engages in an annular channel 26.
