Abstract
The invention relates to a rotor arrangement for a low-pressure turbine of a turbomachine with end-side linkage to a shaft of the turbomachine, comprising a plurality of rotating stages, which are arranged in a flow direction and are connected to one another, wherein the last rotating stage in the flow direction can be linked to the shaft by a rotor disk.
Claims13
A rotor arrangement for a low-pressure turbine of a turbomachine with end-side linkage to a shaft of the turbomachine, comprising:
- a plurality of rotating stages, which are arranged in a flow direction and are connected to one another,
- wherein the rotor arrangement is linked to the shaft in the flow direction at a last rotating stage of the plurality of rotating stages by a rotor disk, wherein the rotor disk is configured and arranged as a conical disk that expands radially outward along an axial length from upstream to downstream;
- the rotor disk having a wall between a radially inner shaft linkage region and a radially outer hub region;
- the wall having a thinnest region;
- the wall having only one widening of the wall thickness from the thinnest region of the wall to the shaft linkage region and only one widening of the wall thickness extending from the thinnest region of the wall to the hub region.
