Abstract

641,709. Turbine nozzles. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. June 15, 1948, No. 16086. Convention date, Aug. 29,1947. [Class 110(iii)] A nozzle structure comprises spaced concentric ring members 28, 29, vane members 30 disposed in circumferential groups therebetween, each vane member having terminal shroud portions making loose engagement with annular portions of the ring members to permit relative radial and circumferential movements, and means for securing certain vane members in each group so as to interlock all the vane members. The member 28 has a mounting face 35 parallel to its axis with a flange 36 at one side, and the member 29 has a mounting face 45 flanked by a pair of peripheral flanges 41, 42. The nozzle structure is assembled by first inserting the shroud member 51 of a vane member 32 through a gap 47 in the flange 42 and sliding it to a position registering with one of the apertures 46 in the mounting face 45. A locking element such as a bolt 60 is then screwed into the aperture 46 and engages a slot 61 in the shroud 51, Fig. 7. A group of vanes 30 is then inserted and slid into engagement with the member 32. A vane member 31 is then inserted and held in position by a locking element 64 which engages a recess 63, Fig. 6, in its shroud 50. This completes the insertion of one group of blades. The process is then repeated until the whole annulus is filled. The sides of the shrouds 50, 51 are inclined to the axis of the nozzle assembly so as to prevent any tendency for an individual vane member to pull away from the annular members 28, 29. The vane members 30, 31 and 32 have radial and axial clearance with respect to the members 28, 29 to allow for expansion.
