Definitions
- the invention relates to a bayonet connection for a Ring housing for a high pressure compressor according to a gas turbine the preamble of the main claim.
- the invention relates to a ring housing, which comprises a plurality of axially arranged housing rings.
- the invention has for its object a ring housing to create the type mentioned, which with a simple structure and simple, inexpensive to assemble the disadvantages avoids the prior art.
- the object is characterized by the features of Main claim solved, the sub-claims show further advantageous Embodiments of the invention.
- the ring housing according to the invention is characterized by a number significant benefits.
- that the housing ring is composed of individual ring segments is.
- a rotational fixation of the bayonet connection and thus a securing against unintentional loosening is preferred Embodiment of the invention by means of detachable radial connecting elements. These can be used as bolts, screws or be formed in a similar manner.
- sealing surfaces can be more preferred Embodiment of the invention a trapezoidal or beveled Have cross-section. It is thus due to the rotational fixation and bracing of the individual parts of the ring housing at the same time also realized a reliable seal without this would require further, additional components.
- sealing surfaces are radial are arranged on the outside of the ring housing.
- the sealing surfaces are radial are arranged on the outside of the ring housing.
- the bayonet design it is possible to have a compact Outer contour of the ring housing (inner housing of the high pressure compressor) to achieve which is a cheaper design of cooling air supplies or the like.
- the figures show a front housing ring 1 and one rear housing ring 2. These are by means of a bayonet connection 3 connected to each other.
- the bayonet connection 3 comprises as can be seen in particular from FIG. 1, against each other plantable trapezoidal elements 10, 11, the each have slanted contact surfaces.
- the two housing rings are connected by means of the bayonet connections inserted into each other and by a predetermined angular amount twisted to each other.
- a rotation lock and fixation takes place by means of a large number of connecting elements 12, which at the same time apply a radial force and become one accordingly lead tight tension of the trapezoidal elements 10, 11.
- the outer contour shows (see Fig. 4) on a relatively smooth outer surface that the Supply of cooling air and the introduction of cooling air openings or something like that.
- stator blade segments 8 are in the interior of the rear Housing ring 2 several stator blade segments 8 by means of Fasteners 12 attached.
- the stator blade segments have Thread inserts 13 in which, as in Fig. 1 shown, bolts or screws screwed are.
- plug elements 4 formed lugs or grooves, which is a pre-fixation and an unintentional Prevent twisting.
- the bayonet connection which is formed by the trapezoidal element 10, 11, both a adequate fixation as well as good power transmission and ensures an excellent sealing effect.
