Abstract

841,815. Elastic fluid turbines; compressors. GENERAL MOTORS CORPORATION. Oct. 7, 1958 [Nov. 6, 1957], No. 31949/58. Class 110 (3). In a stator vane ring assembly for an axial flow compressor or turbine comprising an outer shroud ring 20, an inner shroud ring 27 and stator vanes 24 connecting the two shroud rings, the assembly is made up of segments secured together at the ends of the inner shroud ring portions by a coupling device comprising a lug 52 eccentrically mounted on a rotatable plug 54 on one of the inner shroud segments and on the end of the other inner shroud segments a slot 50 is engaged by the lug. The inner shroud ring is made up of an outer flat band 28, Fig. 4, and an inner hat section 34 forming a box-like chamber 33 wherein is secured a thin metal plate 40 with a semicircular end which is received within the end of the adjacent shroud. The plate 40 is slotted to receive the lug 52 which has an enlarged annular rim part 56. The plug 54 is mounted within a guide member 64 and can be rotated by a tool engaging in the slot 68. Rotation of the plug causes the eccentric lug 52 to bear against the walls of the slot 50 in plate 40 drawing the shroud portions into abutment. A locking finger 72 is provided which engages in the slot 68 in plug 54 preventing further rotation of the plug. Radial movement of the plug is prevented by the abutment face of the enlarged portion 56 of the lug 52 and the face 60 of the plug 54 which bear on plate 40.
