Abstract

867,759. Axial flow turbines and compressors. GENERAL MOTORS CORPORATION. Dec. 2, 1959 [Dec. 3, 1958], No. 40942/59. Classes 110 (1) and 110 (3). A stator vane assembly of an axial flow turbine or compressor comprises a sheet-metal shroud ring with a double-walled portion having slots in which the ends of the stator vanes are secured, each axial end of the shroud ring having a radially outward flange and each flange having around its periphery alternate axially and radially directed portions which bear against corresponding faces of a flange on the turbine or compressor casing. Stator vanes 18 are secured to an inner shroud 20 of zig-zag form and an outer shroud 22. The outer shroud has two annular sheet-metal plates 24, 38 forming a boxlike structure 44. To a recess 28 in the annular sheet-metal plate 24 is fitted an abradable ring 30 to form the rotor blade shroud ring. In the box-like structure 44 are formed slots 46 to receive the stator blades 18 which are welded in position. The axial extremities of the shroud ring are bent to form radially-directed flanges 34, 36, the peripheries of which are crimped to form alternate axially and radially-directed portions 48, 50 which are used to locate the shroud on ridges 14 and flanges 12 in the turbine casing 10. The stator vane assembly is formed in two 180 degree segments each held intermediately by a bolt welded to the annular plate 38 and at its ends by flanges clamped between bolted flanges of the turbine casing 10.
