  • Diaphragm construction for turbomachinery
    Patent number: 5772401
    Abstract: A highly accurate, reproducible and economnical method of manufacturing split diaphragms for use in turbomachinery wherein the diaphragm is first machined axially, and then split across the axial machining to for precision positioning channels into which a pin of matching dimensions is placed to preserve the circularity and stability of the diaphragm when the diaphragm pieces are replaced together about a turbine shaft. Alternatively, the diaphragm is split first and is then machined axially through the split to form precision positioning channels.
