Abstract
758,696. Axial-flow compressors; blade fixing. SIEMENS-SCHUCKERTWERKE AKT.- GES. Aug. 19, 1954 [Aug. 19, 1953], No. 24230/54. Classes 110(1) and 110(3) In an axial-flow compressor, the guide blade tips are secured to a non-resilient substantially annular support 6, Fig. 1, and the guide blade roots are secured to a substantially annular support 7 which is resilient and is adapted to locate the blade roots by co-operation with the compressor casing. The root of each guide blade 4 is chamfered at 9 and sweated into the ring 7, while the tip is slid into an axial groove in the ring 6 and retained by inserted wires 8. The ring 7 has a thin web 10 which overlaps the following rotor blades, and a thickened portion 11 which is a snug fit in the cylindrical bore of the casing. The thin web 10 allows the part of the ring 7 which carries the blades 4 to expand radially. Adjacent root support rings 12, 7 and 13 abut one another and are located and held against rotation by pins such as 14, 15 which engage the thickened parts such as 11, 16 and are inserted in the joint of the casing and held by screws. Ridges such as 25 co-operate with annular webs 19, 20, 21 to form labyrinth glands. In a modification, Fig. 2, two labyrinth seals in series are formed by thin cylinders 30, 31 screwed to an extension 28 of a guide blade support ring 27 and cooperating with ridges 33 on a ring 35 and similar ridges on a cylinder 34. In a further modification, two rows of whirlremoving stator blades are provided after the last row of rotor blading, their two tip-supporting rings being secured together, with a spacer ring interposed, by screws. The two root-supporting rings are spaced from the inner wall of the casing, and radial location is provided by the engagement of the second tip-supporting ring with an annular surface in the casing.
