Abstract
In a steam turbine, apparatus for preventing rotation of a first wheel with respect to a second wheel adjacent the first wheel, wherein the first and second wheels are secured to a shaft of a rotor of the steam turbine by an interference shrink fit, comprises a key disposed in a keyway defined by and between respective hubs of the wheels. The key is exposed to ambient environment of the rotor and is spaced from the axial ends of the keyway to permit steam to flow through portions of the keyway. Key and keyway configurations for prohibiting radial movement of the key are illustrated.
