TURBINE ROTOR AND METHOD FOR THE PRODUCTION THEREOF

The invention relates to a turbine rotor comprising one or several rows of blades with a corresponding number of slots respectively arranged on a radia l plane (RE) which is perpendicular to the rotor (4) longitudinal axis (RM). Each blade consists of a blade footing (1), a blade profile (2) and a cover plate (3), wherein said blade footings (1) of the blade row are densely adjacently integrated into the rotor (4) slots. The cover plate (3) and blad e footing (1) are rhomboid-shaped and continuously tapered. The cover plates ( 3) of the row of adjacently arranged blades form a closed ring and, are larger, in the rotor (4) peripheral direction, at a division tolerance (3.1) than a theoretical division, for forming the closed ring. The faces on the cover plate (3) rhomboids oriented in the rotor (4) peripheral direction are embodied with a twisted angle of 90~ minus a twisted angle alpha with respec t to the longitudinal axis (RM) of the rotor (4). The cover plates (3) and the blade profiles (2) of each blade of the blade row are turned at the angle alpha in the position of 90~ with respect to the longitudinal axis (RM) of t he rotor (4) in such a way that a torsional stress is produced in the blade profile (2) by a force applied on the cover plates (3) around the longitudin al axis of the blades.
