Abstract
The present invention relates to a hydraulic extrusion tool for extruding a rotor shaft for a turbomachine, and a corresponding method. The turbomachine has a structure that is fastened to the rotor shaft by a press fit. The extrusion tool has a first tool part that is configured for the purpose of being arranged on a first side of the structure, and which has a coupling mechanism that is configured for the purpose of coupling the first tool part to the structure, in such a way that the first tool part and the structure cannot move away from each other, at least in one direction along an axis of the rotor shaft; and an induction device that is configured for the purpose of heating the structure by induction in the region of the press fit.
Claims5
A hydraulic extrusion tool for extruding a rotor shaft for a turbomachine, comprising
- the turbomachine including a structure that is fastened to the rotor shaft by a press fit,
- a first tool part that is arranged on a first side of the structure, and has a coupling mechanism that couples the first tool part to the structure in such a way that the first tool part and the structure cannot move relative to each other, at least in one direction along an axis of the rotor shaft;
- and
- at least one induction device that is configured for the purpose of heating the structure by induction in the region of the press fit;
- wherein the first tool part has a hydraulic actuator that is configured for the purpose of pushing or pulling the rotor shaft out from the structure against the press fit, when an assembled state is present in which the first tool part is coupled to the structure,
- wherein the at least one induction device is integrated in the first tool part, and
- wherein a second tool part that is arranged on a second side of the structure, the second side being opposite to the first side;
- wherein a second induction device is integrated in the second tool part.
