ABSTRACT:
In a steam turbine having a wheel secured to a rotatable shaft by a key and cooperating keyway, a passageway provides steam flow communication between an axial end of the keyway and a first location on an axial end of the wheel. A channel provides steam flow communication between the other axial end of the keyway and a second location on the axial end of the wheel. The first and second location are preferably diametrically opposed. Steam may be directed to enter the passageway at the first location, flow along the keyway and channel and exit at the second location, thereby ventilating the key and keyway.
