Abstract
A rotary shaft to hub connection, such as that used between a centrifugal compressor or pump and a shaft. The hub includes inner and outer axial extending members that fit within inner and outer annular grooves formed within the rotary shaft so that a tight fit between the shaft and the hub is maintained during high speed rotation. An inwardly extending projection is formed on the outer axial extending member of the hub that forms a tight fit against the shaft.
