Abstract
1,061,370. Axial-flow compressors. GENERAL MOTORS CORPORATION. Jan. 27, 1966 [March 3, 1965], No.3662/66. Headings F1C and F1T. In a ring of adjustable stator vanes, e.g. for a multi-stage axial-flow compressor, Fig. 1 (not shown), the radially inner end of each vane 32 has a pair of tangs 96 passing through an aperture 72 in a band 70 and a pair of blade adjustment limiting, arcuate slots 84, Fig. 6 (not shown), in a band 82. Circular shims fitted over the tangs comprise a steel shim 74 and p.t.f.e., shims 78, 88, the shims 74, 78 and aperture 72 forming a radial bearing and the shims 78, 88 bearing against opposite faces of the band 82. The shims, band 82 and a retaining disc 92 are held in contact between shoulders 98 on the tangs, and a convex portion 100 on the vane by bowed leaf springs 102. The vane can rock slightly if deflected by gas loading to eliminate binding at the inner end of the vane. Rings 87 provide seals with the surface of a rotor part 28. The rotor comprises a number of blade carrying elements 28 comprising end discs fixed to the shaft and intermediate rings splined one to another. The radially outer end of the vane has a stub shaft 44, Fig. 2 (not shown), which passes through an opening in an outer casing comprising four quarter-cylindrical segments. The opening is fitted with p. t. f. e., washers (42), (47) which provide a seal and radial and thrust bearing surfaces. The stub shaft carries a crank-arm (34) having a spherical projection fitted within a p.t.f.e., socket (66) seated on a spring in an annular channel in a segmented control ring (36). The portion of the crank-arm fitted over the stub shaft is in the form of a sleeve split longitudinally and provided with a conical surface which is forced into wedging contact with a complementary surface on a metal washer (46) by a nut (58) screwed on to the end of the stub shaft. Those crank-arm sleeve portions and stub shafts associated with the vanes adjacent the flanges for joining the casing segments together, are longer than the others.
