Schaeffler auf der COMPAMED 2014

Integrierte Lagertechnologie in der Medizintechnik

Ob f r C-B gen, Patientenliegen, OP-Tische oder Deckenstative - f r W lzlager, Linearf hrungen und Antriebe gelten stets h chste Anforderungen an Pr zision, Laufruhe und Sicherheit. Unter den Marken INA und FAG sowie den Untermarken IDAM und Barden bietet Schaeffler ein weltweit einzigartiges Know-how und Produktportfolio f r alle bewegten Komponenten und Systemen in der Medizintechnik und ist damit der ideale Entwicklungspartner und Lieferant. Im Rahmen der Compamed 2014 zeigte Schaeffler innovative und bew hrte L sungen, die sowohl die hohen Qualit ts- und Sicherheitsanforderungen im Bereich Medizintechnik erf llen, als auch ein Mehr an Zuverl ssigkeit und Flexibilit t bieten und das Einsatzspektrum der medizintechnischen Ger te erweitern.

Lagerintegriertes Messsystem - L sungen f r Industrie 4.0

Das speziell f r den Einsatz in Computertomographen entwickelte, einbaufertige System FAG SIMTUS tr gt erheblich dazu bei, dass Rundum-R ntgenaufnahmen zeitlich immer k rzer und die Bildqualit t immer hochwertiger wird. Hinter FAG SIMTUS, abgeleitet von Special Integrated Mechatronic Turning Unit System, verbergen sich direktangetriebene Lagereinheiten der FAG Aerospace GmbH & Co. KG als einbaufertige Komplettl sungen, die h chsten Anforderungen an computergest tzte bildgebende Verfahren in Krankenh usern oder radiologischen Kliniken gerecht werden. Ein lagerintegriertes, hochaufl sendes Messsystem dient der Bildgebung im Computertomographen.

Vorteile des FAG SIMTUS sind geringe Scanzeiten aufgrund hoher Drehzahlen des Systems, gestochen scharfe Bilder selbst aktiver Organe wie z. B. des schlagenden Herzens, sowie absolute Ger uschreduzierung.

Als Antriebseinheit kommt ein Torquemotor von IDAM (INA - Drives & Mechatronics GmbH & Co. KG) zum Einsatz, w hrend die mechanischen Komponenten, das speziell entwickelte Lager und auch die Montage zur Kernkompetenz des Gesch ftsbereichs FAG Aerospace z hlen. Die elektronischen Schnittstellen, mechanische Anschlussgeometrie, Genauigkeiten und Steifigkeiten werden mit dem Kunden gemeinsam entwickelt.

Elektromechanische Hubs ule: Einbaufertige Komplettl sung f r C-B gen erf llt h chste Anforderungen

Die elektromechanische Hubs ule zeichnet sich durch eine hohe und exakte F hrungsqualit t aus. Robust konstruiert und kompakt gebaut, kann die Hubs ule Lasten von mehreren hundert Kilogramm sicher, dauerhaft und zuverl ssig bewegen. Das kompakte mechatronische System ist f r die hohen Anforderungen bei C-B gen in der Medizintechnik konzipiert, l sst sich jedoch einfach auf die Anspr che anderer Industrie-Anwendungen adaptieren. Die Hubs ulen werden als komplette, anschlussfertige Einheiten geliefert, die sich problemlos in bestehende bzw. neu zu erstellende Anlagen integrieren lassen.

F r die hohe und exakt reproduzierbare F hrungsqualit t sorgen zwei gegen berliegende Hochleistungs-Linearf hrungssysteme. Die Endposition des Hubwegs wird durch elektronische Endschalter erfasst. Als Antrieb dient ein b rstenloser 24-Volt-Gleichstrommotor.

Linearanwendungen f r Patientenliegen und OP-Tische

Gr tm gliche Beweglichkeit gepaart mit hoher Robustheit erfordern Patientenliegen, OP-Tische und Zahnarztst hle. Die perfekte L sung hierf r sind INA-Linearf hrungen. Insbesondere die Kugelumlaufeinheiten KUVE-B und KUSE erf llen hohe und h chste Anforderungen. Aufgrund ihrer vier bzw. sechs W lzk rperreihen sind sie extrem tragf hig. Ausgelegt f r hohe Lasten pro F hrungswagen gew hrleisten die Kugelumlaufeinheiten alle Erfordernisse hinsichtlich Qualit t, Belastbarkeit, Laufeigenschaften und Sicherheit.

Lager f r Deckenstative - leichtg ngig, hoch belastbar, ger uscharm

Moderne OP-R ume zeichnen sich durch Flexibilit t beim Personaleinsatz und den verwendeten Ger ten aus. Am Boden verlegte Leitungen geh ren aus Sicherheits- und Reinigungsgr nden der Vergangenheit an. Nach wie vor steigt die Anzahl der w hrend einer Operation verwendeten Ger te. Wohin aber mit all den Bildschirmen, medizinischen Ger ten, Computern und Leitungen? Die L sung sind Deckenstative, deren Schwenkarme die Ger te tragen und eine flexible und individuelle Positionierung erm glichen. Die Deckenstative m ssen dabei hohe Belastungen aufnehmen, leicht beweglich sein und ausreichend Platz f r die Versorgungsleitungen (Strom, Sauerstoff, Daten etc.) bieten. Speziell f r Deckenstative eignet sich das Axial-Schr grollenlager AXS. Es wird paarweise eingebaut, nimmt hohe Lasten und Kippmomente auf und erm glicht eine leichtg ngige und ger uscharme Bewegung. Der kleine Lagerquerschnitt - also die kleine radiale Bauh he bei gro em Innendurchmesser - vergr ert die Querschnitts ffnung des Tragarmgelenks im Deckenstativ und erleichtert so die Durchf hrung der zahlreichen Versorgungsleitungen.

Das Axial-Schr grollenlager AXS ist zudem mit integrierter elektromechanischer Bremse erh ltlich. Diese verhindert, dass sich die Lagereinheit im stromlosen Zustand drehen kann, weil Federn die Ankerplatte gegen den Bremsbelag dr cken. Das Deckenstativ ist somit sicher fixiert. Im bestromten Zustand zieht ein Elektromagnet die Ankerplatte gegen die Federn und gibt den Bremsbelag frei, die Einheit kann rotieren und damit leichtg ngig in eine neue Position gebracht werden.
