  • Publication number: 20130129478
    Abstract: A gas turbine rotor for a gas turbine is provided. The gas turbine rotor includes a compressor rotor shaft, a turbine rotor shaft and a coupling device frictionally connecting the two rotor shafts, wherein the coupling device is designed in such a way that the friction connection also exists when the two rotor shafts are displaced relative to one another. In this case, the turbine rotor shaft is lengthened at the end facing the compressor rotor shaft in such a way that said turbine rotor shaft overlaps with the compressor rotor shaft in the axial direction and the coupling device connects this lengthened end of the turbine shaft to the compressor rotor shaft in the radial direction.

  • Patent number: 8226366
    Abstract: Disclosed is an axial rotor section for a rotor of a turbine, on which a sealing element, which is provided on an end side surface, is secured by means of a bolt against movement in the circumferential direction, with the bolt being reliably secured against becoming loose by means of a securing plate. One particular advantage of the invention is the comparatively simple and low-cost design, comprising a securing plate, a bolt, holes and grooves. Furthermore, these components can be fitted and removed quickly, because of their simple geometry.
