Method for straightening coupling shafts

摘要

A method and apparatus are provided for straightening a coupling shaft comprising a tubular member having a midship tube shaft affixed at one end thereof, with the midship tube shaft mounted in a center shaft support bearing assembly. The coupling shaft is rotatably supported at the end opposite the midship tube shaft and at the center shaft support bearing which rotatably supports the midship tube shaft of the coupling shaft. The coupling shaft is rotated relative to an indicator for measuring radial misalignment thereof, and the radial misalignment is measured at one or more locations along the midship tube shaft. A force is applied to the coupling shaft to permanently deflect the same and thereby reduce any observed radial misalignment.
