Plug-and-Play-fertige Linearsysteme f r den Werkzeug- und Sondermaschinenbau
Um den sehr kurzen Entwicklungszeiten im Werkzeug- und Sondermaschinenbau gerecht zu werden, fordern die Hersteller von ihren Lineartechnik-Lieferanten heute nicht mehr allein Linear-Komponenten, sondern in erster Linie Plug-and-Play-fertige Subsysteme einschlie lich Engineering, Antriebstechnik und weiterer Services. Das schlie t auch die Endmontage, die Verkabelung, die Parametrierung der Steuerung und die Inbetriebnahme ein. Genau auf diese funktionsfertigen und projektspezifischen Linearsysteme hat sich Schaeffler Lineartechnik in Homburg mit dem Bereich Systeml sungen spezialisiert: Ein intelligenter Mix aus konfektionierbaren und leistungsf higen Linearsystemkomponenten aus dem Schaeffler-Programm, mechanischen und elektrischen Antriebselementen von namhaften Zulieferern und Partnern bilden die Basis f r funktionsfertige und wirtschaftliche Linearsysteme und Systeml sungen.
Wirtschaftliche L sungen durch Funktionsintegration
In hauseigene und selbst entwickelte Aluminium-Strangpressprofile integrieren die Schaeffler-Ingenieure Linearf hrungen, Zahnriemenantriebe und Kugelgewindeantriebe, Planetengetriebe, Messsysteme, Drehgeber, Laufwagen, Schmiersysteme, Endschalter, Abdeckungen usw. Mit der Integration von vielen Funktionen in wenige Bauteile sind wirtschaftliche Linearsysteme realisierbar. ber die Standardkomponenten hinaus entwickelt und fertigt Schaeffler kundenindividuelle und ma geschneiderte Linearsysteme. Diese werden mittels FEM speziell auf den jeweiligen Belastungsfall hin optimiert. Mit einem Programm an Direktantrieben, Servomotoren, Steuerungen und Sensoren werden die Linearsysteme auch elektrisch funktionsfertig entwickelt und gefertigt. In Verbindung mit dem umfangreichen Schaeffler-Programm an W lz- und Linearlagern sowie dem W lzlager-Know-how entstehen so immer wieder innovative L sungen mit hohem Integrationsgrad.
Teleskopmodul MTKUSE: Mehr Freiraum f r Werkzeugmaschinen
Teleskopachsen bieten im Vergleich zu Standard-Linearachsen den gro en Vorteil, dass Sie sich nicht ber den gesamten Verfahrweg erstrecken und so den Arbeitsraum f r andere Maschinen und Prozesse freigeben k nnen. Teleskopmodule als Nebenachsen eingesetzt, bieten dem Werkzeugmaschinenbau daher die M glichkeit, seine Maschinen sehr viel flexibler zu gestalten. Auch die bergabe in Bereiche hinter Schutzw nden oder getrennten Arbeitsr umen wird so m glich.
Speziell f r solche Nebenachsen, wie z. B. Pick-and-Place-Anwendungen oder die Werkzeug bergabe, entwickelte die Schaeffler-Lineartechnik das Teleskopmodul MTKUSE. Darin sind drei Pr zisions-Kugelumlaufeinheiten so bereinander angeordnet, dass der m gliche Verfahrweg mehr als doppelt so lang ist wie das Basismodul selbst. Die Lineareinheit ist in beide Richtungen teleskopierbar. Ein Servogetriebemotor ist au en an das Aluminiumprofil angeflanscht und treibt ber ein Zahnstangengetriebe das Modul an. Es k nnen auf Kundenwunsch Servomotoren verschiedenster Hersteller und entsprechend vorbereitete spielarme Pr zisions-Planetengetriebe montiert werden. Endschalter und Wegmesssysteme werden nach Kundenwunsch integriert. ber den Servoregler ist mittels Stromerfassung und Schleppfehler berwachung eine indirekte Zustandsauswertung des Reibmomentes und damit des Lagerzustandes m glich.
Linearpr zisionstisch LTP: pr zise und wiederholgenaue Bewegung
Pr zisionslineartische LTP kommen zum Einsatz, wenn Werkzeuge bei der Bearbeitung oder Kontrolle pr zise und mit gro er Wiederholgenauigkeit bewegt werden. Der Linearschlitten ist in einer hochgenau gefertigten Aluminumplatte auf pr zisen Kugelumlaufeinheiten gelagert. Die Kugelumlaufeinheiten verleihen dem LTP-Tisch einen ruhigen, ger uscharmen Lauf mit gleichzeitig geringem Verfahrwiderstand. Angetrieben wird die Einheit ber einen Servomotor und einen Kugelgewindetrieb. Alternativ ist auch eine direkt angetriebene Version m glich. Wegmesssysteme und Positionsschalter werden kundenspezifisch appliziert. Die Linearpr zisionstische LTP sind in drei Baugr en und optional auch in einer schwingungsd mpfenden Graugussvariante erh ltlich. Zum Schutz vor Fremdk rpern und Fl ssigkeiten k nnen die LTP mit Faltenbalg oder mit einer Metallteleskopabdeckung ausgestattet sein. Um je nach Kundenwunsch Servomotoren verschiedenster Hersteller montieren zu k nnen, wurde ein Kupplungsgeh use KGEH als offene Schnittstelle entwickelt. Auch bei den LTP ist ber den Servoregler eine indirekte Zustandsauswertung des Reibmoments und damit des Lager- bzw. Spindelzustands m glich. Einsatz finden die Linearpr zisionstische als Hilfsachsen an Werkzeugmaschinen, bei der Werkzeug bergabe oder auch als Antrieb f r die Laserzuf hrung zur Werkzeugbeschriftung und Codierung.
