Method for balancing and assembling a turbine rotor

摘要

A method for balancing and assembling a turbine rotor 2 including at least one turbine disk 3 and a compressor rotor 15 of a gas turbine. A front cover disk 6 is fastened by connections 10 to the turbine disk 3, and the turbine disk 3 is balanced together with the cover disk 6. The turbine disk 3 and the cover disk 6 are braced by a clamping device 19, 20. The bolted connections 10 are then removed and the turbine disk 3 and the cover disk 6 are connected to the compressor rotor 15 by bolted connections 10. The clamping device 19, 20 is then removed.
