Abstract
Described is a fixation device for blading of a turbo-machine, in which, longitudinally to a mounting groove (1), a plurality of blades (31, 32) is positioned, and in which, between at least two blades (31, 32) positioned adjacent to each other inside the mounting groove (1), a mounting gap is provided, having two insertion elements constructed as collar halves (41, 42) that can be inserted into the mounting gap, and each of which has a width adapted to the width of the mounting gap and which enclose between themselves a gap space (5) into which a wedge element (43) can be inserted that can be wedged in such a way that both collar halves (41, 42) are fixed in a force-derived manner by means of the wedge element (43) inside the mounting groove (1). The invention is characterized in that the wedge element (43) is provided with at least one connecting element (45) towards the side of a blade (31, 32) and that at least one of the two blades (31, 32) adjoining the wedge element (43) is provided with a counter-contour (46) corresponding to the connecting element (45), so that the wedge element (43) and the blade enter (31, 32) into an intimate shape-mated connection with each other.
