Document Type and Number:
Japanese Patent JPS60252103
Kind Code:
A
Abstract:
In a steam turbine, a device for keying hubs of adjacent wheels together, wherein the wheels are not an integral part of the shaft of a rotor of the steam turbine and may be secured to the shaft by an interference shrink-fit at the surface of a bore through the hub of the wheel, comprises a substantially I-beam shaped key disposed in a keyway formed between adjacent hubs. A lip extends axially from the outer periphery of a pair of opposing end faces of adjacent hubs, the outboard surface of one lip of the pair of opposing end faces being in close proximity to the outboard lip of the other lip of the pair of opposing end faces. A respective pair of lands on each respective pair of opposing end faces defines a substantially radial slot respectively between the pair of lands. Streamlined fillets respectively transition the leading and trailing faces of each respective member of the pair of lands to the respective opposing end face. Radial extensions of the key contact the shaft and an inner radial portion of one of the lips.
