Definitions
- the invention relates to a rotor according to the preamble of claim 1.
- the invention further relates to a thermal fluid machine with such a rotor.
- Thermal turbomachinery includes steam and gas turbines as well as rotary compressors. These usually have a rotatably mounted rotor surrounded by a stationary housing.
- the fixed components of a thermal turbomachine are collectively referred to as a stator.
- a flow channel extending in the axial direction of the turbomachine for a compressible flow medium is arranged.
- On the rotor usually in the flow channel projecting and combined into groups of blades or rows of blades blades are attached.
- the blades serve to drive the rotor shaft by momentum transfer from a hot and pressurized flow medium.
- the thermal energy of the flow medium is thus converted in its relaxation in mechanical energy that can be used for example to drive an electric generator.
- the rotor of a gas turbine which is also referred to as a rotor, is usually exposed to high mechanical and thermal stress. Above all, due to the high temperature of the working medium and the forces acting on the rotor during operation of the gas turbine, the rotor components forming the rotor are heavily stressed. Nevertheless, in order to be able to ensure operational safety on the one hand and to keep the manufacturing costs of the runner within acceptable limits on the other hand, a large number of design options have been proposed in the past.
- a proposed embodiment of the rotor for example, by the production of a part feasible.
- a production method is comparatively complicated in the manufacturing process.
- no order-independent prefabrication and no parallel processing of individual parts is possible, resulting in high production throughput times.
- a greater axial distance between the adjacent blade rings must be accepted in order to produce with appropriate tools necessary for attachment of the blade contours can.
- these production-related relatively large distances between the blade rings deteriorate the rotor dynamics.
- each rotor part designed as a rotor disk has an axially extending recess through which the tensioned tie rod can extend. By screwed at the end of the tie rod nuts this can be stretched, whereby the end face adjacent rotor parts can be clamped together. The rotor parts are then pressed together by the tie rod and transmit the forces acting on them over a torque Hirth toothing mentioned, which each frontally arranged forms a positive connection between two adjacent rotor parts.
- the rotor of the gas turbine is arranged at the end by suitable bearings in the housing of the turbine.
- suitable bearings in the housing of the turbine.
- nuts can also shell side more complex components be angeschankerend noted screwed, which in addition to the tension of the rotor parts also allow other functions, such as the bearing of the rotor in a radial and / or thrust bearing.
- the Stülpringe create an axial connection between the rotor discs and tie rods to reduce its vibrations.
- the Stülpringe are not used in the area of a hollow shaft.
- the invention is therefore an object of the invention to provide a runner of the type mentioned, which ensures safe operation of the gas turbine even with increasing overall length. Furthermore, the vibration amplitudes of the tie rod, especially in the region of the central hollow shaft should be kept as small as possible.
- the tie rod is supported in its central region.
- the support wheel arranged between the turbine-side section and the compressor-side section constitutes a rotor component radially supporting the tie rod.
- the invention is based on the consideration that for a reduction of the oscillation of the tie rod this should be supported on one of the rotor components, wherein the thermally induced different expansions of the rotor components should still be compensated.
- the fact should be taken into account that due to the increasing requirements with respect to the performance of the turbine whose length increases, whereby the natural frequency of the tie rod approaches the operating speed of the gas turbine.
- the reduction of Switzerlandschwingungen is achieved in that the tie rod is supported radially by the support wheel.
- the jockey wheel constitutes a further, supporting rotor component, the jockey wheel preferably being - in the axial direction of the rotor - connected to the tie rod in a region in which the amplitudes of the vibrations occurring during operation of the turbine reach their maximum values.
- the jockey wheel is arranged between the turbine-side section of the rotor and the compressor-side section of the rotor, i. H. at the place of maximum deflection of the tie rod in case of possibly occurring Switzerlandankerschwingungen.
- this area may be between the compressor section and the turbine section. This allows a support of the tie rod to a vibration particularly effective position.
- the support of the tie rod is preferably achieved by non-positively and / or positively with the support wheel connected to the tie rod.
- the support wheel can be shrunk on the tie rod.
- This type of connection is particularly suitable, since thus a particularly rigid connection between the support wheel and the tie rod is made possible in a simple manner.
- the thermally induced different expansions of the rotor components occurring during operation of the gas turbine, in particular between the support wheel and the tie rod can be compensated in an advantageous manner, preferably by providing at least one of the rotor components with a profile.
- the connection between the tie rod and the support wheel be set elastically, such that the differential volume is largely compensated due to the different heating of the rotor components.
- the hub of the support wheel is provided with a profile seen in the longitudinal section of the rotor crowned profile. With such a connection side compliant hub shape, stresses and cracks in the rotor component can be prevented.
- the spherical profile of Stauerradnabe can also be described in other words: the cylindrical surface of the tie rod opposite surface of the Ceiankerbohrung the support wheel is - seen in the axial direction - arched, the curvature is directed to the outer surface.
- the support wheel is connected to two adjacently arranged rotor parts by means of a Hirth gearing.
- a Hirth gearing Using such an axially effective connection, the torques acting on the rotor can be transmitted and transmitted via the support wheel.
- a radial guide for receiving different thermal and centrifugal deformations is ensured by means of the Hirth gearing. In particular, thus the occurrence of vibrations during operation of the gas turbine due to a thermally induced non-uniform expansion of the support wheel can be reduced.
- the support wheel is provided with cooling holes, which are preferably arranged uniformly around the hub.
- a rib structure is formed due to the recesses introduced for cooling in the support wheel, which allows the passage of a cooling medium in the axial direction of the rotor.
- the surface of the support wheel can be increased on the one hand by the introduced openings and a smooth transport of the cooling air within the rotor can be made possible by means of cooling air openings formed in this way.
- the tie rod can be surrounded by a number of concentrically arranged cooling separation tubes for a suitable guidance of cooling medium, wherein these divide the channel formed between the tie rods and the rotor components encompassing these into a number of radially adjacent partial cooling channels. This ensures that the cooling of the rotor components, in particular the cooling requirement of the respective turbine stage can be carried out accordingly.
- the cooling air separation tubes are axially divided into two sections for receiving the support wheel, such that their ends pointing in the direction of the support wheel can be guided into provided, introduced in the support wheel receiving grooves.
- the cooling air separation pipes thus realize on the one hand an improved heat dissipation, and on the other hand, the heat capacity of this rotor component can be reduced.
- a so-called middle hollow shaft is arranged, which is axially divided in at least two pipe sections in the case of the use of a support wheel according to the invention.
- the pipe sections are substantially the same length.
- the advantages achieved by the invention are in particular that a particularly safe operation of the gas turbine is made possible by the associated with the tie rod jockey wheel with its increasing length.
- the vibration amplitudes can be kept particularly small by the appropriate support of the tie rod.
- a targeted increase in the natural frequency of the tie rod with comparatively little effort can be realized through this system.
- the thermally induced relative movements between the tie rod and trained as a support wheel rotor part can be compensated particularly well.
- necessary cooling is ensured by means extending in the axial direction of the rotor cooling air, even with passage of cooling air with different pressures and temperatures, which are separated by separable tubes feasible.
- FIG. 1 A rotor 2 of a gas turbine with a number of individual, held together by a tie rod 4 and assembled into a unit rotor parts 6 is in FIG. 1 shown in a longitudinal section.
- the rotor 2 has a compressor-side section 1 and a turbine-side section 3, each having a number of rotor parts 6.
- the respective rotor parts 6 designed as rotor disks are connected on the connection side, i.
- Each of the rotor parts 6 is provided for the spaced passage of the tie rod 4 with an axially extending bore 10.
- a middle hollow shaft 11 is arranged between the compressor-side rotor parts 6 and the turbine-side rotor parts 6. End of the tie rod 4 is bolted to a rotor part 7, 9, whereby all interposed rotor parts 6 are held together and clamped.
- the present between the rotor parts 6 recesses 8 serve to guide a cooling medium for cooling the rotor components by cooling air is supplied via a cooling channel formed between the tie rod 4 and the rotor part 6.
- rotor parts 6 In order to support the tie rod 4 in a suitable manner by him surrounding rotor components, ie rotor parts 6, is between two rotor parts 6, preferably between compressor side Section 1 of the rotor 2 and turbine-side section 3 of the rotor 2, another trained as a support wheel 14 rotor part 6 inserted.
- the previously one-piece central hollow shaft 11 has been divided into two pipe sections 11a, 11b, between which the support wheel 14 is preferably clamped.
- the support wheel 14 in this case represents a further rotor component.
- the rotor parts 6 and the support wheel 14 are clamped together by means of tie rods 4, wherein the support wheel 14, in contrast to the other rotor parts 6 is additionally positively and / or positively connected to the tie rod 4 ,
- the central hollow shaft 11 comprising at least two pipe sections 11a, 11b, between which the support wheel 14th is clamped.
- the picture according to FIG. 2 shows a cross section through the compressor output side portion of the rotor 2 in detail.

- the picture according to FIG. 3 shows a provided with cooling holes 12 support wheel 14, wherein the depth of 12 serving as cooling holes 12 recesses corresponds to the material thickness of the support wheel 14 at this point.
- the recesses 12 are introduced uniformly distributed over the cross section of the support wheel 14, so that a uniform cooling of the support wheel 14 can be done and thus stresses and uneven deformations are avoided.
- the heat transfer to the cooling medium is particularly effective, since due to the introduced by the introduced into the wheel body 15 recesses 12 increased cooling surface more heat can be removed.
- a serration 18 is provided on both sides of the outer rim of the support wheel 14 on both sides.
