Abstract
In the device, the turbine blades are anchored with blade feet, which are profiled like teeth, to correspondingly shaped axial grooves of a wheel disk. An axial gap is left between each blade foot end and the base of an axial groove, in which gap a securing element is disposed. The securing element can be bent on both ends, which protrude out from the gap, directed opposite each other against faces of the wheel disk and a blade foot, and is clamped in a wedged manner in the relevant axial gap between the groove base and the blade foot. The securing element bridges over a recess, which is formed in the blade foot to receive a balancing mass.
