A turbine diaphragm assembly includes inner and outer endwall rings, nozzle vanes each with a tenon extending outwardly from one end, and inner and outer retaining rings. The inner and outer endwall rings each have inner and outer radial surfaces and a plurality of openings extending radially through the inner and outer endwall rings about their circumference. Each of the vanes is positioned between the inner and outer endwall rings, with one of the tenons protruding radially inward through one of the openings in the inner endwall ring and with the other tenon protruding radially outward through one of the openings in the outer endwall ring. The inner radial surface of the inner endwall ring is located adjacent to the outer radial surface of the inner retaining ring with the portion of the tenons protruding radially inward through the openings in the inner endwall ring and positioned in a first circumferential groove in the outer radial surface of the inner retaining ring. The outer radial surface of the outer endwall ring is located adjacent to the inner radial surface of the outer retaining ring with the portion of the tenons protruding radially outward through the openings in the outer endwall ring and positioned in a second circumferential groove in the inner radial surface of the outer retaining ring. |
