Abstract
A gas turbine has at least one guide blade ring, whose guide vanes are axially and radially fixed via detachable locking elements. A shell ring is configured as a freely machinable component having projections bearing a stop surface and mating surfaces. A holding piece is provided for each guide vane, which engages into corresponding recesses on an upstream shell ring. The holding pieces are held in a position determined by the locking elements, via spring clips.

In a gas turbine having a turbine housing, and guide vane rings and moving blade rows arranged axially side by side, an arrangement for axially and radially fixing guide vanes of the guide vane ring wherein stop surfaces of the guide vanes that serve for fixation are arranged on locking elements, which are structurally separate from the turbine housing.
A gas turbine, comprising:
- a turbine housing;
- guide vane rings and moving blade rows arranged alternately in axial sequence within said housing;
- and
- fixing means for axially and radially fixing guide vanes of the guide vane ring within said housing;
- wherein,
- said fixing means comprise stop surfaces of the guide vanes;
- and
- said stop surfaces are provided on locking elements that are structurally separate from the turbine housing.
