Abstract
The invention relates to a rotor end piece () for rotors () of thermal turbomachines with a circumferential slot (), consisting of two end piece halves (') having side faces (′) opposite one another in the installed state and of a wedge () which is pushed in between them and which, in the installed state, is anchored in the side faces (′) of the end piece halves (′) in a form-fitting manner, the rotor end piece () being arranged in the axial direction of the rotor () between two moving blades (′). It is characterized in that each of the end piece halves (′) is fastened in the axial direction of the rotor () to the two adjacent moving blades (′) by means of one interlocking connection (′) each. These four interlocking connections (′), instead of the rotor (), now absorb the axial forces which are caused by the centrifugal force and the caulked wedge (). In this way, disturbing rotor vibrations are advantageously avoided.
