Definitions

  • the invention relates to a method for producing a machine carrier for a wind power plant, wherein a main carrier is produced by casting a casting as a cast part of cast iron with nodular graphite and a rear carrier is made as a welded part.
  • the invention further relates to a machine carrier for a wind energy plant with a main carrier designed as a casting and a tail carrier designed as a welded part, as well as a wind energy plant.
  • Wind turbines usually have a tower, at the top of which a nacelle with a rotor with a rotor hub with rotor blades is arranged, which drives a generator during operation.
  • the gondola accommodates machine parts such as bearings, shafts and the generator, as well as, if necessary, a gearbox.
  • the machine parts are carried by a floor platform or a machine carrier, which is rotatably mounted on the tower.
  • the machine carrier transmits the entire rotor forces to the tower via the azimuth bearing, picks up the heavy loads of the machine parts and is correspondingly rigid and solid.
  • Machine carriers can be designed completely in one piece as a welded construction or as a cast component.
  • a machine carrier consists of two parts, wherein both the front main carrier and the rear carrier, which is connected to the main carrier at the rear side, may be welded or cast.
  • the main task of the rear carrier is to carry the weight of the generator and, where appropriate, of a transformer, an inverter and control cabinets.
  • the strength design is less critical than the highly stressed main beam. More important here is the stiffness design, as the generator must be exactly aligned with the gearbox. Dynamic loads of the rear carrier result mainly from vibrations and inertial forces.
  • Main girders are currently manufactured in some wind turbines as castings made of cast iron, so produced as a casting in a casting process. This has the advantage that even complicated shapes are easy to produce.
  • the casting material has vibration-damping properties that a welded part made of steel does not have. This is in the environment in a nacelle of a wind turbine, in the strong vibrations and thus strong sound emissions may arise advantageous.
  • cast iron with a lower density than steel, has good compressive strength and, due to its embrittlement, good dimensional stability, which makes it particularly suitable for use as a machine carrier.
  • An example of a suitable cast iron is spheroidal graphite cast iron, ie spherical graphite deposits additionally has a comparatively high tensile strength.
  • the rear carrier may be a welded part, that is, welded together from a plurality of steel parts, ie steel carriers, steel tubes and steel plates, in particular made of rolled steel. Because of the higher tensile and breaking strength compared to cast iron, the rear carrier with the same load capacity on a lower weight.
  • connection between the main carrier and the rear carrier is usually designed as a flange connection.
  • the rear carrier is flanged to the machine frame by means of suitable screw.
  • Corresponding screw and flange connections between the main carriers and the rear carriers require regular maintenance in order to guarantee a lasting, stable hold. Flange connections are also bulky and can be difficult to access due to the tight space in a nacelle.
  • a flange connection in a power house of a wind turbine is in EP 2 161 445 A1 shown.
  • the nacelle is formed of a front segment and a rear segment, which are carried together by an azimuthal module.
  • the front segment includes a molded front frame or cast base that receives the load of the rotor and a gearbox.
  • the rear segment includes a welded rear frame that carries a generator and power electronics. The rear frame is hung in the front frame and the connection then fixed by bolts.
  • WO 2005/056373 A1 relates to a body component for a support frame structure a self-supporting vehicle body, which is designed as a thin-walled steel casting.
  • a steel sheet is integrated in the body component such that an inner part of the steel sheet is embedded in the steel casting and an outboard part of the steel sheet protrudes from the steel casting.
  • EP 1 880 784 A2 discloses a composite of a light metal cast component and at least one steel component, in which the steel component is galvanized and partially cast in thechtmetallgussbauteil.
  • the composite can be welded to other steel components or assemblies via the steel component.
  • EP 1 050 357 A1 discloses a sealed connection of turbine parts having a first cast turbine part and a second metal turbine part joined together by pouring.
  • the second part has an end part with a curved contour, which is cast in the first turbine part.
  • the area of the angled contour of the cast-in end part is a multiple of the area of an end part with flat end faces without angulations.
  • a preferred angled contour has the shape of a Christmas tree. The shape ensures a positive and positive as well as a vapor and gas-tight connection between the two turbine parts.
  • the invention is therefore based on the object of providing a method for producing an improved machine carrier, an improved machine carrier and a wind energy plant with a corresponding machine carrier, which eliminate the aforementioned disadvantages.
  • a method for producing a machine carrier for a wind turbine wherein a main carrier is produced by casting a casting as a cast iron castings with spheroidal graphite and a rear carrier is produced as a welded part, which is further developed by at least one weldable Eingussteil is provided
  • a main carrier is produced by casting a casting as a cast iron castings with spheroidal graphite and a rear carrier is produced as a welded part, which is further developed by at least one weldable Eingussteil is provided
  • the invention is based on the basic idea that the machine carrier is produced in a composite casting process.
  • a weldable Eingussteil partially poured into the main carrier or in a connecting piece of the main carrier so that it protrudes from the main carrier out.
  • the connecting piece is a part or region of the main carrier to which the rear carrier is attached. The protruding from the cast body of the main carrier out part of the sprue is or will be welded to the rear carrier, but may also be part of the rear carrier in the invention.
  • the composite casting technique offers the possibility of creating a permanent and maintenance-free connection between castings and steel parts.
  • the embedding of the sprue in the cast body constitutes an at least partially cohesive connection, as well as a welded joint or an integral connection of the protruding from the cast body part of the sprue with the rear carrier.
  • a connection between the main carrier and rear carrier is made, which is more durable and stronger than a bolted flange, which produces only a force and / or positive connection and can loosen under constantly changing load.
  • the method according to the invention offers increased design freedom in the arrangement of the connection point and a simple design possibility of the cast support. This leads both to a casting cost optimization and to a welding cost optimization.
  • the elimination of the flange leads to a cost savings for flange material and flange processing and to a better utilization of the available in a nacelle of a wind turbine room.
  • molded parts can also be arranged in inaccessible places in the nacelle, for example below the transmission.
  • a screw flange has to be regularly maintained and therefore has to be arranged further to the rear, that is to say at a greater distance from the tower axis, in order to be accessible.
  • the cast-in part is first partially cast in the rear-side connecting piece of the main carrier, and then the rear carrier is welded to a part of the sprue protruding on the main carrier.
  • the at least one casting is particularly easy to position when casting the main carrier.
  • the result of the casting process in this case is a cast main carrier with at least one partial casting projecting out of the cast body of the main carrier. This is used in the further manufacturing process as welding surface for the welded rear carrier.
  • first of all the rear carrier is produced with a cast-in part and then a part of the sprue part in the production of the main carrier in the rear-side connecting piece of the main carrier is poured.
  • the cast-in part can already be a part of a carrier or steel carrier of the rear carrier or be welded thereto and serves to be molded in during the production of the main carrier.
  • the connection of the main carrier with the rear carrier during manufacture of the main carrier is made by pouring instead of a subsequent welding.
  • Both versions require a precise alignment of the rear carrier to the main carrier.
  • a device for positioning and alignment is required because there are no correction options after the casting.
  • the method according to the invention is advantageously developed if the cast-in part is preheated prior to pouring into the rear-side connecting piece of the main carrier. This promotes alloy formation in the edge zone to the cast material. Also advantageously, the main carrier alone, together with a casting or together with the rear carrier subjected to an annealing process, whereby the desired material structure is set, which has the advantages of stability, damping properties and tensile and tear resistance.
  • a machine carrier for a wind turbine with a substantially as a casting of a cast iron formed with ductile iron main carrier and a substantially formed as a welded part rear carrier, which is further developed by at least one weldable Eingussteil is provided which is partially cast in a rear-side molded connection piece of the main carrier and outside of the connecting piece of the main carrier the rear carrier is connected, in particular by means of a welded joint.
  • the cast-in part may also be integral with the rear carrier or with a supporting part of the rear carrier. In this case, a part of the sprue part protrudes from the connecting piece of the main carrier.
  • a connector a part or region of the main carrier to which or to which the rear carrier is recognized.
  • the main carrier and the connector are preferably molded together as a unit.
  • An inventive machine carrier is manufactured in a composite casting technique and has no bolted flange connection between main carrier and rear carrier.
  • the casting at least in the area which is cast in the main carrier, having a profiled surface or a profiled edge, whereby the casting and the connecting piece of the main carrier are positively connected to each other, in addition to the material connection of the sprue connection and a positive connection between the casting and reached the surrounding casting of the main carrier.
  • the additional positive locking prevents slipping out of the sprue the cast body of the main carrier even if the cohesive connection loses part of its strength due to material fatigue.
  • a corresponding profiled surface or profiled edge may for example be a sawtooth profile or a suitable other profile.
  • the rear carrier has two or more carriers or carrier arms, each with one or more sprues.
  • the sprues are preferably designed as paired horizontal plates.
  • the at least one upper cast part can be formed with a larger cast surface than the at least one lower cast part. This takes into account the fact that the upper die is subjected to a tensile load and tends to pull this die from the casting of the main carrier, while the lower die under a compressive load tends to slide into the main carrier is pressed into it.
  • At least one casting is designed as a substantially horizontally or vertically arranged sheet metal or as a sheet having in cross-section an L-profile, a C-profile, a U-profile a box section or a tubular cross-section.
  • Corresponding sheets are for example burned out of sheet steel, laser cut or punched.
  • the substantially horizontally arranged sheets efficiently absorb loads resulting from the weight of the generators and inverters arranged on the rear carrier, while substantially vertically accommodating sheets, in particular loads from transverse accelerations, for example, from movements of the nacelle about the tower axis transferred to the main carrier. It can also be advantageously arranged a plurality of vertically and horizontally arranged sheets or castings in an L-shape, C-shape, U-shape or box shape to each other.
  • the carrier or carrier arms of the rear carrier by means of diagonal braces, diagonal braces or thrust plates become additionally or alternatively advantageously provided Pushing Association are connected. This serves to absorb loads from lateral accelerations and prevents parallelogram movement with the casting parts as pivotal points.
  • At least one casting is designed as a cast steel part.
  • Steel castings make an ideal transition between the softer cast iron of the main beam and the welded rear carrier, since the material properties of cast steel, in particular strength, density and damping properties, lie between those of the main carrier and those of the rear carrier. This reduces damage to the connection of the rear carrier and the main carrier, resulting from the stress of a joint between materials with different mechanical properties.
  • Steel castings have the advantage that they are easy to shape due to the casting process. They are also weldable.
  • a cohesive embedding of molded parts in the casting of the main carrier is advantageously favored if at least one casting is coated, in particular with zinc, tin or a Zn-Al alloy.
  • the coating promotes alloy formation and thus the intermetallic connection between the cast part and the cast material.
  • the coating may preferably be applied by spray metallizing, for example by thermal spray galvanizing or zinc flame spraying.
  • a typical tower head diameter for a 2 megawatt wind turbine is between 2.4 m and 3 m.
  • An advantageously compact design, the cost savings, is achieved in this context, when the main carrier has a tower flange whose center is located on a tower axis, wherein a distance of a sprue to the center of the tower flange less than 250% of a radius of a bolt circle of Turmflansches is, more preferably less than 200%, more preferably less than 180%.

  • an inverter 9 which adjusts the electric current generated by the generator 8 so that it is in a private or public power grid can be fed.
  • a machine carrier with a main carrier 10 and a rear carrier 11 is shown in the lower part of the nacelle 1.
  • the main carrier 10 supports the support 6 of the slow shaft and the rotor hub 2 and the gearbox 7.
  • the rear carrier 11 carries electrical components such as the generator 8, control and switching cabinets and optionally a transformer and the inverter 9.
