Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an improved rotor shaft for a turbomachine, subjected to a high thermal load, such as a gas turbine, being equipped with a multiplicity of radially extending cooling bores, the rotor shaft being advantageous over the state-of-the-art technology especially with regard to its lifetime.SOLUTION: At least one inlet portion 132 of cooling bores 130 is formed as a projecting plateau 124 projecting beyond an outer circumference contour 122 of a rotor cavity 120. 【課題】半径方向に延在する複数の冷却孔を備える、ガスタービンのような高い熱負荷に曝されるターボ機械用のロータシャフトを改良して、特にその耐用期間に関して技術的現状を超える好適なものを提供する。【解決手段】冷却孔１３０の少なくとも１つの入口部分１３２は、ロータ空洞部１２０の外周輪郭１２２を越えて突出する隆起平坦部１２４として形成されている。【選択図】図３
