Abstract
A rotor end piece (1) for rotors (2) of thermal turbormachines is provided with circumferential slot (3), including two end piece halves (4, 4′) having side faces (5, 5′) opposite one another in the installed state and top surfaces (6, 6′) adjoining one another. The rotor end piece (1) side faces (5, 5′) of the end piece halves (4,4′) are connected to one another in a form-fitting manner. To this end, the side faces (5, 5′) are designed in such a way that a dovetail interlocking connection of the two end piece halves (4, 4′) is preferably realized. The interlocked end piece halves are then secured with a weld (8). The firm anchoring of the rotor end piece (1) achieved in this way prevents detachment during operation and damage to the turbomachine caused as a result.
