Abstract
The use of spring clamping clips between two adjacent guide vane shafts leads to a defined force on the bearing points of the guide vane in the guide bush. The seating force, resulting from the clamping force and the flow-related lift/drift forces, of the guide vane in the guide bush is therefore always positive and the guide vane rests constantly in the guide bush.
