1. Apparatus for determining the magnitude of static linear displacement of a rotating shaft from an aligned reference position at each respective one of a plurality of bearings supporting said shaft, said shaft tending to vibrate differently than when aligned due to said static displacement at least one of said bearings, said apparatus comprising:

  • means for determining at each of said bearings the linear vibration amplitude of said shaft caused by said static displacement of said shaft from at least one of said reference positions;

    means responsive to said means for determining for producing an indication representing the magnitude of said static displacement of each said bearings from said aligned reference position which displacement corresponds to and is the cause of the determined linear vibration amplitude at each of said bearings; and

    means for shimming each of said bearings in accordance with the magnitude of said static displacement of each said bearing, an amount of shimming for each respective bearing being substantially equal to and opposite from said static displacement at each respective bearing.
