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