Reliability - Made by Schaeffler: H here Zuverl ssigkeit f r Windkraftanlagen

Wirtschaftliche Windkraftanlagen brauchen zuverl ssige Komponenten. Als einer der weltweit f hrenden W lzlagerhersteller und Entwicklungspartner der Branche produziert Schaeffler seit ber 30 Jahren Lagerungen f r Windkraftanlagen. Mit diesem umfassenden Know-how bietet Schaeffler die passende Lagerl sung f r jede Windkraftanlage und ein ganzheitliches Konzept, das die Zuverl ssigkeit von Windkraftanlagen weiter steigert.

W lzlagern kommt in Windkraftanlagen eine Schl sselrolle zu. Sowohl in der Onshore- als auch in der Offshore-Windkraft sind die Anforderungen an die Zuverl ssigkeit der Komponenten in den vergangenen Jahren erheblich gestiegen. Das Wachstum der Anlagen hin zu Multi-Megawatt-Kraftwerken f hrt zu h heren Kr ften und Momenten, die die Komponenten immer st rker beanspruchen. Gleichzeitig verursachen Stillstandszeiten und Wartungsarbeiten insbesondere bei Offshore-Anlagen immer h here Kosten.

Schaeffler Wind-Power Standard (WPOS)

Mit dem Wind-Power-Standard (WPOS) tr gt Schaeffler den steigenden Anforderungen an die Zuverl ssigkeit von Anlagen und Komponenten in der Windkraft Rechnung. Dieser h chste Qualit tsstandard f r Produkte und Prozesse sichert weltweit eine optimale Qualit t und Zuverl ssigkeit und bietet auch f r die Windkraft Qualit tsma st be, wie sie bereits in der Automobilindustrie oder in der Luft- und Raumfahrt erfolgreich umgesetzt werden.

Um die hohen Standards sicherzustellen, setzt Schaeffler ber die gesamte Prozesskette hinweg in enger Zusammenarbeit mit Kunden und Lieferanten auf abgestimmte und transparente Prozesse, ein definiertes nderungsmanagement, eine strenge Qualit ts berwachung und eine umfangreiche Dokumentation. Eine gezielte Lieferantenentwicklung sichert h chstes Qualit tsniveau von Beginn an, etwa bei der Qualit t des eingesetzten Stahls. So entwickelt Schaeffler gemeinsam mit den Kunden die optimale L sung f r jede Lagerstelle. Die FAG und INA Produkte nach Schaeffler Wind-Power-Standard erhalten das Kennzeichen WPOS.

Zuverl ssigkeit - Made by Schaeffler bedeutet noch mehr. Neben dem Wind Power Standard bietet Schaeffler weitere Ma nahmen, um die Zuverl ssigkeit von Windkraftanlagen zu erh hen.

Optimale Auslegung mit hochmodernen Berechnungs- und Simulationsprogrammen

Neben der langj hrigen Erfahrung und dem umfassenden System-Know-how der Spezialisten bei Schaeffler sichern insbesondere hochmoderne Berechnungs- und Simulationsprogramme eine optimale Auslegung der Windkraftlager. Schaeffler ber cksichtigt dabei das gesamte System vom einzelnen W lzlager und seinen Komponenten ber die Anschlusskonstruktion bis hin zum kompletten Antriebsstrang, der mit eigens entwickelten. Mehrk rper-Simulationsprogrammen abgebildet und optimiert wird.

Realit tsnahe Tests auf Schaeffler ASTRAIOS

Erg nzt und validiert werden die Berechnungen auf leistungsf higen Pr fst nden. Auf einem der modernsten und gr ten Gro lagerpr fst nde der Welt, k nnen Lager bis 3,5 Meter Au endurchmesser getestet werden. ASTRAIOS simuliert die realen Lasten und Momente, die in einer Windkraftanlage auftreten. Damit tr gt Schaeffler entscheidend zu einer schnelleren und zuverl ssigeren Auslegung von Windkraftanlagen bei und erh ht deren Wirtschaftlichkeit und Sicherheit.

Asymmetrische FAG-Pendelrollenlager f r gesteigerte axiale Tragf higkeit

Asymmetrische FAG-Pendelrollenlager verf gen ber einen h heren Druckwinkel auf der axial belasteten Lagerreihe und einen flacheren Druckwinkel auf der haupts chlich radial belasteten Lagerreihe. Die asymmetrischen Druckwinkel reduzieren Gleitbewegungen im Antriebsstrang durch eine noch h here axiale Steifigkeit der Lager. Triondur C, eine lamellenartig aufgebaute, amorphe Kohlenwasserstoffschicht, sorgt als Beschichtung der Rollen zus tzlich f r eine Reibungsreduzierung und einen hohen Verschlei schutz bei Mischreibung.

Innovative L sungen gegen White Etching Cracks (WEC)

Schaeffler verf gt ber umfassende Pr fm glichkeiten, um WEC zu erzeugen, die Ursachen zu untersuchen und L sungskonzepte zur Senkung des WEC-Risikos zu entwickeln. Diese k nnen beispielsweise in einer optimierten Auslegung des Lagers, in der Wahl eines WEC-resistenten Werkstoffes oder auch in einem verbesserten Schmierstoff-Konzept liegen. Die von Schaeffler empfohlene Produktl sung sind durchgeh rtete, br nierte W lzlager. Das Schichtsystem Durotect B bietet neben weiteren Vorteilen einen erh hten Schutz gegen ber WEC, der durch eine umfassende Felderfahrung statistisch belegt ist.

Hohe Anlagenverf gbarkeit durch Condition Monitoring

Schaeffler bietet umfangreiche Dienstleistungen und Produkte rund um die Zustands berwachung an, z. B. Fern berwachung und Diagnose, Offline-Messungen, Endoskopie, Thermografie und Drehmomentmessung. So k nnen die Kosten f r Instandhaltungsma nahmen gesenkt und die Verf gbarkeit von Windkraftanlagen erh ht werden.
