  • This functional position of the blocking element is ensured that the blocking element engages in a certain rotational position relative to the cover plate the edge of the opening blade end side by means of a cam formed on the blocking element and that the blocking element located in this rotational position is secured against rotation relative to the cover plate about a longitudinal axis of the blocking element. Securing the rotational position of the blocking element is achieved in that a part of the blocking element is plastically deformed and thereby engages in a beard opening of the keyhole-like opening.

  • the functional position of the cover plate is secured when the securing bolt extends partially in the formable on the guide portion of the cover plate guide opening and the web is at least partially disposed in the recesses. This is effected in particular by the fact that the web extends radially with respect to the rotor disk when the rotor blade is arranged on the rotor disk.
  • the thickening formed on the cover plate or the guide section which can be formed thereby enables the formation of a longer guide opening and thus a good guidance of the securing bolt.
  • the guide portion completely surrounds the guide opening.
  • the fact that the outer diameter of the securing bolt corresponds to the diameter of the guide opening is intended to mean that the securing bolt can be inserted in a form-fitting manner into the guide opening.

Without the rounding at the end of the securing bolt, damage to the securing wire could occur during bending of the safety wire and / or under mechanical stress during operation of a correspondingly formed gas turbine. This could in turn the durability of a corresponding fuse the functional position of the locking bolt are affected.
