Abstract
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.
