Patent ID: 8641365

Claim:
A rotor for a gas turbine, comprising: a compressor-side section; a turbine-side section; a plurality of individual compressor-side rotor components a plurality of individual turbine-side rotor components; a tie-bolt; wherein the plurality of individual compressor-side and turbine-side rotor components are pressed to each other using a tie-bolt and assembled to form a rotor unit, wherein for each tie-bolt provided, each rotor component has a tie-bolt opening which extends centrally in an axial direction of the rotor, wherein the tie-bolt extends centrally through the respective tie-bolt opening leaving a space between the tie-bolt and the respective rotor component, wherein a support wheel is arranged as a rotor component between the turbine-side rotor section and the compressor-side rotor section and radially supports the tie-bolt, wherein the support wheel has a central hub through which the tie-bolt extends, wherein the support wheel is connect to two adjacently arranged rotor components using Hirth toothing, wherein the hub of the support wheel is provided with a crowned profile on a connection side.
