Zusammenfassung:An arrangement is presented for axially securing rotating blades in a rotor, having a shaft collar on whose external circumference rotating blade securing grooves which extend in the axial direction of the rotor are provided. At one end side face of the shaft a projection is arranged in the region of the securing grooves, in which projection a circumferential groove which is open radially towards the outside is provided and said projection having securing grooves which are arranged in each rotating bade, sheet-metal-shaped sealing elements which each engage in the circumferential groove and in the securing groove and form an end side sealing ring in the circumferential direction being provided for axially securing the rotating blades, and at least one of the sealing elements comprising a sheet metal strip which is attached to said sealing ring in order to secure the sealing elements against displacement in the circumferential direction.
