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 the 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.

An oil supply system for a stationary turbomachine is provided. A safe operation of the turbomachine is enabled even at ambient temperatures of up to 60&#xb0; C. for a plurality of hours in a novel connection arrangement of the components of the oil supply system, such as the oil tank, pump a, and heat exchanger, as well as the pipeline system, without one of the components having to be designed for a further increased operating temperature. The oil tank has two regions stacked horizontally one above the other for storing the oil. The two regions are largely or completely separated from each other by a separating element.
