A turbine blade assembly composed of a rotor which is rotatable about a turbine axis of rotation and a plurality of turbine blades supported by the rotor, each blade having a root and the rotor being provided with a groove shaped for holding each root in a manner such that the root and groove have mutually contacting surfaces which apply a radially inwardly directed restraining force to the root, the root further having a bottom facing the turbine axis and the groove having a base which is located radially inwardly of, and faces, the root bottom. The mutually contacting surfaces of the root and the groove are pressed together by means of at least one disc spring compressed between the root bottom and the groove base.

A method and apparatus for supporting a journal bearing includes a three-part support key. The top piece is a rectangular member having a male cylindrical surface formed to mate with a female cylindrical groove formed axially with respect to a rotor in the bearing shell, and a female cylindrical surface formed perpendicularly to the male cylindrical surface. A middle piece having a top surface adapted to conform with the female cylindrical surface of the top piece and a flat bottom surface which is mated with the top piece and inserted within a keyway formed in the bearing pedestal. Thereafter, a bottom piece in the form of a variable thickness shim is inserted between the flat bottom surface and the keyway to align the rotor.
