STEAM TURBINE WHEEL ANTIROTATION MEANS |
摘要 |
The steam turbine rotor includes a number of turbine wheels secured to a shaft by an interference shrink fit between each wheel and a corresponding step surface on the shaft. The step surfaces have decreasing radii over a portion of the axial length of the shaft. Each wheel includes a hub section proximate the shaft and each hub section has a shoulder portion of greater radial dimension that the radially innermost surface of the hub section is secured. A member or finger protrudes from one shoulder and mates with a longitudinal slot on one of the step surfaces of the shaft. Relief grooves are also provided on the shaft and hub section.
