Description
Stand der TechnikState of the art
Die Erfindung geht aus von einer Lagerung einer Rotorwelle einer eine tragende Struktur aufweisenden Windenergieanlage (WEA), nach der Gattung des Anspruchs 1.The The invention is based on a bearing of a rotor shaft of a carrying structure having wind turbine (WEA), according to the Genus of claim 1.
Die
Entwicklung der kommerziellen Nutzung der Windenergie an Land (Onshore)
nahm vor ca. 20 Jahren ihren Anfang. Seitdem werden Windenergieanlagen,
die in der Regel aus einem Turm und aus einer mittels Windrichtungsnachführungslager
(i. d. R. ein- oder doppelreihige Kugeldrehverbindungen) um eine
vertikale Achse drehbar auf dem Turm gelagerten, der Windrichtung
nachführbaren und bremsbaren Gondel, die eine mit mindestens
einem Rotorblatt versehene um eine horizontal drehbar gelagerte
Rotornabe aufweist, bezüglich der auftretenden Lasten, deren
Ableitung in den Turm und fertigungstechnischen Aufgabenstellungen
immer weiter fortentwickelt. Eine derartige Windenergieanlage wird
in der Offenlegungsschrift
Moderne Windenergieanlagen (WEA) nutzen die im Wind enthaltene Bewegungsenergie durch die Energieumwandlung anhand von Rotorblättern. Eine große Kraftkomponente der an den Rotorblättern entstehenden sog. Auftriebskräfte ist der Rotorschub, der nicht in Energie umgewandelt werden kann, sondern über eine geeignete Lagerung über den Turm in das WEA-Fundament geleitet werden muss. Bei der weit verbreiteten WEA-Bauweise mit Getriebe wird die Lagerung der langsam drehenden Rotorwelle mittels Lagergehäusen inkl. Kugellager (auch als Lagerbock oder Stehlager bezeichnet) realisiert, die als Standard-Komponenten großer Wälzlagerhersteller (z. B. SKF, FAG, INA) angeboten werden. Wie der Fachliteratur entnommen werden kann, sind diese Lagereinheiten im Falle von Ungenauigkeiten in Auslegung und Fertigung verschleißanfällig, wodurch kostenintensive Reparaturarbeiten und damit verbundene unwirtschaftliche Ausfallzeiten entstehen.modern Wind turbines (wind turbines) use the kinetic energy contained in the wind the energy conversion based on rotor blades. A big Force component of the resulting on the rotor blades so-called. Buoyancy is the rotor thrust that is not in energy can be converted, but over a suitable storage over the tower must be routed into the WEA foundation. At the far widespread WEA construction with gearbox, the storage of the slow rotating rotor shaft by means of bearing housings including ball bearings (also referred to as bearing block or pillow block bearing) realized as Standard components of large bearing manufacturers (eg SKF, FAG, INA). As taken from the literature These storage units are in case of inaccuracies wear-prone in design and manufacture, whereby costly repair work and associated uneconomical Downtime arises.
Die Erfindung und ihre VorteileThe invention and its advantages
Die erfindungsgemäße Lagerung einer Rotorwelle einer eine tragende Struktur aufweisenden Windenergieanlage (WEA), mit dem kennzeichnenden Merkmal des Anspruchs 1, hat demgegenüber den Vorteil, dass die Windenergieanlage zur Lagerung der Rotorwelle ein Lagergehäuse aufweist, das über mindestens drei Aufnahmen an die tragende Struktur der WEA angebunden ist, so dass auf diese Weise die Lastableitung aus dem im Lagergehäuse befindlichen lagerbildenden Mittel (z. B. Kugellager) optimiert ist und, da zumindest ein Großteil der auf die Rotorwelle einwirkenden Lasten, insbesondere Schublasten, durch das Lagergehäuse abgetragen werden, der Eintrag von Lasten z. B. in das Getriebe reduziert wird.The Inventive storage of a rotor shaft a a supporting structure having wind turbine (WEA), with the characterizing feature of claim 1, in contrast, has the Advantage that the wind turbine for storing the rotor shaft a bearing housing having over at least three pictures are connected to the supporting structure of the wind turbine, so that in this way the load dissipation from the located in the bearing housing bearing-forming means (eg ball bearings) is optimized and, since at least a majority of the loads acting on the rotor shaft, in particular thrust loads, are removed by the bearing housing, the entry of loads z. B. is reduced in the transmission.
Die erfindungsgemäße ein Lagergehäuse (Rotorwellen-Lagergehäuse) aufweisende Lagerung für eine Windenergieanlage (WEA) mit seiner Mehrpunkt-Anbindung an die tragende Struktur der WEA (auch Maschinenträger genannt, ein Gondelchassis z. B. in Schweiß- oder Guss-Ausführung bzw. Gondel als selbsttragendes Fachwerk) beherbergt bevorzugt ein Rotorwellen-Kugellager, welches die am Rotor der WEA entstehenden Lasten (sog. Schublasten aus aerodynamischem Auftrieb) aufnimmt. Diese Bauweise mit Mehrpunkt-Anbindung ermöglicht eine gleichmäßigere Ableitung der Lasten z. B. aus dem Rotorwellen-Kugellager in das Rotorwellen-Lagergehäuse und weiter in die tragende Struktur der WEA, was der hohen geforderten Lebensdauer der Kugellager im 20-jährigen Betrieb einer WEA dienlich ist. Auf diese Weise wird die Lastableitung z. B. bei einem Dreipunktlager z. B. alle 120° des Kugellagerumfangs realisiert.The A bearing housing according to the invention (rotor shaft bearing housing) having storage for a wind turbine (WEA) with its multi-point connection to the supporting structure of the WEA (also Machine carrier called, a gondola chassis z. In welding or cast design or nacelle as a self-supporting framework) preferably houses a rotor shaft ball bearing, which the am Rotor of the WEA resulting loads (so-called thrust loads of aerodynamic Buoyancy) absorbs. This design with multi-point connection allows a more uniform discharge of the loads z. B. from the rotor shaft ball bearing in the rotor shaft bearing housing and further into the supporting structure of the WEA, what the high demanded Lifespan of ball bearings in 20-year operation of a WEA is useful. In this way, the load dissipation z. B. at a three-point camp z. B. every 120 ° of the ball bearing circumference realized.
