Abstract:
1. A method for assembling a first rotor and a second rotor having non-complementary flange openings, the method comprising: providing a male protrusion in substantially a center of a first rotor flange of the first rotor; providing a female opening corresponding to the male protrusion in substantially a center of a second rotor flange of the second rotor; coupling an at least partially threaded dowel into each of a plurality of circumferentially spaced flange openings in the first rotor flange; mating the male protrusion to the female opening and extending the plurality of at least partially threaded dowels through corresponding flange openings in the second rotor flange; progressively drawing the first rotor and the second rotor closer by threading a threaded collar onto each at least partially threaded dowel, while ensuring alignment between the first rotor flange and the second rotor flange by periodically measuring axial position of the flanges relative to a reference; with the first rotor flange and the second rotor flange contacting, machining at least one of: a flange opening in the first rotor flange and a flange opening in the second rotor flange to make complementary flange openings; removing the plurality of at least partially threaded dowels; and assembling the first rotor to the second rotor by coupling a fastener in each set of complementary flange openings.
