Definitions

  • a vane foot of the vane is attached to the vane support (also TVC - turbine vane carrier), in particular by means of a sliding block.
  • the guide vane can be attached to the vane carrier by simple means.
  • the bore is arranged such that the spacer element 15 in a leak-free Area 16 impinges on the rotor 10, so that it is ensured that no sealing tips 21 of the rotor 10 are damaged by the spacer 15, if at a disassembly of vanes 2 then freely movable U-ring 13a, for example, due to gravity in the direction of the rotor 10 moved.
  • FIG. 3 is a radially outer end, ie a vane root 18, of the vane 2 shown attached to a vane support 13b.
  • the two respective hooks facing each other or open that is, they are arranged oriented opposite.
  • the vane support 13b has an exception bay 19 which additionally provides space for removal.
  • the exception bay 19 accessible, so that sections Leitschaufelfuß 18, in particular those on the in FIG. 3 molded right engagement means 8b, can dive into the exception bay 19 to the in FIG. 3 left engagement device 7a disengaged from in FIG. 3 also to bring left counter-engagement device 8a.
