More Information
Summary:The present invention relates generally to manufacturing rotor assemblies, and, more specifically, to the assembly thereof. A plurality of rotors are individually measured for determining relative eccentricity between forward and aft annular mounting ends thereof. The measured rotor eccentricities are stacked analytically to minimize eccentricity from a centerline axis. The rotors are then assembled axially end-to-end to correspond with the stacked measured eccentricities thereof.
