Axial running blade for gas turbine - has running blades with blade feet anchored in axial grooves distributed over periphery of wheel plate

摘要

Each axial groove encloses a deepened formation (T) formed between the groove base and the foot end. In each deepened formation a filling piece (5) locating on the groove base and a securing plate (6) are fitted. The securing plate bridges over a gap (S) running along the deepened formation (T) between the foot end and the filling piece (5). The securing plate ends emerging from the deepened formation are bent around against the face surfaces of the filler piece (5), the wheel plate (4) and the blade foot (2), whereby a rotor imbalance is compensated by at least one filling piece. USE/ADVANTAGE - To eliminate rotor imbalance in an axial throughflow compressor or turbine.
