Definitions
- the present invention relates to the field of gas turbine technology. It relates to a rotor for a gas turbine according to the preamble of the claim 1.
- Such a rotor is e.g. known from US-A-4,505,640.
- FIG. 1 A section of a rotor of the type mentioned at the outset is exemplary in FIG. 1 shown.
- the rotor 10 comprises a rotor disk 11, on the circumference of which one A large number of rotor teeth, which run essentially in the axial direction 15 mutually separate receiving slots 13 are arranged. In the slots 13 come coming from below in the rotor disc 11 extending Cooling air inlets 14, through the cooling air for cooling the rotor blades 16 provided.
- the rotor blades 16, each of an airfoil 17, one Blade root 19 and a platform arranged above the blade root 19 18, are with the blade root 19 in the axial direction in the receiving slots 13 inserted and are detachably held there, with a positive connection usually through a fir-tree-like design ("fir-tree") of the cross-sectional profile is achieved.
- fir-tree fir-tree-like design
- the cooling air (or some other suitable one) brought in by means of the cooling air supply 14 Cooling medium) is through channels (not shown) in the interior of the blade root 19 led into the interior of the (hollow) airfoil 17, flows there and is then through outlet openings on the airfoil 17 and / or on the platform 18 left out.
- the rotor blades 16 do not have to for thermal reasons only the actual airfoil 17 due to the cooling medium flowing inside are cooled, but also the blade root 19 and the above the Platform 18 arranged on the blade root.
- US-A-4,012,167, US-A-5,639,216 and US-A-5,848,876 proposed, for example, horizontally running inside the platform
- Such internal cooling of the platform is, however, manufacturing-related very complex because it is difficult, for example with cast Blades to form corresponding channels.
- cooling air that flows past the attachment for Use cooling of the platform or at least to flush the cavities.
- the amount of cooling air is because of the fit between the blade root and Recording slot depends and is more like a leak, indefinitely.
- the essence of the invention is between the outside of the blade root and form the inside of the receiving slot cooling air channels, the can be easily manufactured as recesses, for example, and the cooling medium lead directly from the cooling air supply into the cavities.
- a preferred embodiment of the rotor according to the invention is characterized in that that the cooling air channels at least partially as recesses in the Blade root and / or receiving slot are formed. These recesses can be formed in a particularly simple manner directly during casting or through subsequent material removal can be produced.
- the cooling air channels are formed as recesses, which run vertically between the mouth of the cooling air supply and the cavities.
- Cooling air channels are formed as recesses, which on the one hand from the Mouth of the cooling air supply horizontally outwards to one end of the Blade root and on the other hand vertically up to the front Cavities run that the front recesses to the outside are sealed by cover plates that axially secure the rotor blades
- cover plates that axially secure the rotor blades
- Axial locking plates arranged on the face side in the receiving slots are provided, and that the axial locking plates are used as cover plates become.
- a cooling air duct is formed as a recess, which from the mouth of the cooling air supply leads horizontally outwards to an end face of the blade root, that for axially securing the rotor blade in the receiving slot on one end arranged axial locking plate is provided, and that the axial locking plate is so shaped that between the axial locking plate and the front of the blade root vertically up into the cavities extending cooling air duct is formed.
- the formation of the cooling air channels can at least in part through a comparatively simple shaping of the axial locking plates be effected.
- FIG. 2 shows a rotor with additional ones in a representation comparable to FIG. 1 vertical cooling air channels according to a first embodiment of the invention reproduced.
- the same parts have the same reference numerals provided, as in Fig. 1.
- the cavities 21 below the platform 18 are here supplied with cooling air directly by means of vertical cooling air channels 22.
- the cooling air ducts 22 run directly from the mouth of the cooling air supply 14 in the bottom of the receiving slot 13 to the cavity 21 and flush the cavity 21 with cooling air and simultaneously cool the underside of the platform 18.
- the cooling air ducts 22 are located in the vertical center plane of the rotor blade 160 and are made by recesses formed in the blade root 19, either when casting the rotor blade 160 molded in or later formed by material removal (e.g. milling) become.
- the cross section of the cooling air channels 22 is in accordance with the required Cooling air volume designed.
- cooling air channels on the blade root to be formed by corresponding recesses is shown in Figs. 3 and 4.
- cooling air channels 23, 24 running vertically through cutouts are kept free, is led upwards into the cavities 21 by the cooling air.
- To the outside Limitation of the cooling air channels 23, 24 is used to axially secure the rotor blade 161 axial locking plate inserted into corresponding grooves 27, 28 26.
- To connect the vertical cooling air channels 23, 24 with the mouth of the A further horizontal cooling air duct 25 is provided for the cooling air supply 14 through a recess or recess on the underside of the blade root 19 is formed.
- the cooling air then flows according to the arrows in Fig. 4 from the Cooling air supply 14 and via the cooling air channels 25 and 23 or 24 upwards in the cavities 21 below the platform 18.
- blade root in the one shown in FIG. 1 Maintain shape and the additional cooling air channels through complementary Recesses or recesses in the receiving slots 13 of the To form rotor disk 11.
- FIGS. 5 to 8 Another type, the cooling air channels according to the invention in the area of the blade root Forming 19 is shown in FIGS. 5 to 8.
- the recesses necessary for this are not provided on the blade root 19 itself, but on one end for axially securing the rotor blade 162 used axial locking plate 260 or 261.
- the vertical cooling air channels 30 through in the axial locking plate molded beads 29 and 29 'formed (one of the beads is assigned to a blade root).
- the invention results in manufacturing technology that is particularly simple A defined flushing of the cavities below the platforms, through which the entry of hot gas is reliably prevented, as well as a good one Cooling of the platforms themselves.
