The GT rotor is composed of a plurality of discs and two shafts. The GT gas turbine rotor may be bent after assembled because of each part has its geometric tolerance.The scheme must be carry out to straight the bend rotor. In oder to get well high speed balance, the surface of each disc excircle, torque tube and disc adaptor can’t be remachine on lath after assemble. We can machine the journal of the shaft on horizontal lathe to straight the slightly bended rotor. For the serious bended rotor, we must disassemble the rotor and change the parallelism of two side of the disc flange on vertical lathe to get a straight rotor. This attic detailed analysis these two schemes and proposed specific actions measures, then the problem of how to straight a bent GT rotor get well solution.
