Patent ID: 8128374

Claim:
A securing element for securing rotor blades in position in grooves of a rotor base body of a turbine engine rotor, the grooves extending at least predominantly in the axial direction, the securing element comprising: a plate-shaped base member, the base member having an approximately centrally disposed recess formed between two end sections of the base member so as to define a middle section of the base member extending between the two end sections, the two end sections having mutually in parallel extending bearing surfaces, wherein the middle section is dimensioned in such a way that, for the assembly operation, a ram-type tool is capable of acting exclusively on the securing element in the middle section at a distance from the two end sections thereof, thereby plastically deforming the middle section in regions where edge sections of the tool rest; and a projection formed in the region of an end section of the base member and, once the assembly operation has taken place, is disposed radially inwardly, and the projection determining a center-of-mass of the securing element in such a way that centrifugal forces acting during operation of the turbine engine rotor press the projection against a sealing surface.
