摘要: A rotor (20) for a compressor, in particular in a gas turbine, has a number of rotor blades (25) which are arranged around the rotation axis of the rotor (20) in the form of a rim and are each held in a circumferential recess (21) on the rotor (20) by a blade root (26), with the blade root (26) having a widening lower part (27) which engages behind two shoulders (24) that are formed on the side walls of the recess (21). In such a rotor, the life is lengthened in that the recess depth (T) of the recess (21) is substantially greater than a minimum recess depth (Tmin) which results in the rotor (20) having sufficient strength in the area of the blade attachment for starting, based on the predetermined material characteristics of the rotor (20) and the operating conditions of the compressor.

摘要: 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.
