Mehr Zerspanungsleistung bei h herer Pr zision
Schaeffler bietet Rundtischlager-Baureihe jetzt in X-life-Qualit t
Mit einer kompletten berarbeitung der INA Rundtischlager-Baureihe YRTC erreicht Schaeffler noch h here Drehzahlen und h chste Kippsteifigkeiten. Damit stehen Betreibern von Werkzeugmaschinen neue Wege zu mehr Zerspanungsleistung bei gleichzeitig h herer Pr zision zur Verf gung.
Schaeffler pr sentiert seine INA Rundtischlagereinheit YRTC jetzt in X-life Qualit t. Als Ergebnis der kompletten Neuauslegung wird das bisherige Leistungsspektrum hinsichtlich Steifigkeit und Drehzahlen nochmals deutlich bertroffen. Das neue Design der YRTC-Lager bietet um 50% reduzierte und sehr gleichm ige Reibmomente. Dadurch lie en sich die Grenzdrehzahlen teilweise um bis zu 80% anheben. Gleichzeitig konnten die Kippsteifigkeiten um bis zu 20% gesteigert werden. Mit diesen Leistungsmerkmalen erh lt die Baureihe nun auch das X-life-Premiumsiegel.
Technische Merkmale der neuen YRTC-Lager sind Kunststoff-K figsegmente mit speziellem Fettreservoir, konstruktiv optimierte Lagerringe, sowie eine optimierte W lzk rpergeometrie. Au erdem verf gen die Lager ber exzellente Plan- und Rundlaufgenauigkeiten. Optional stehen f r diese Baureihe auch lagerintegrierte Messsysteme zur Verf gung. Die YRTC-Lager eignen sich besonders f r den Einsatz in W lzfr smaschinen sowie in hochbelasteten Positionier- und Schwenkachsen f r die Ultrapr zisionsbearbeitung.
Baureihe YRTC im Vergleich zu den Baureihen YRTS und ZKLDF
Schaeffler verf gt mit den drei Baureihen YRTC, YRTS und ZKLDF ber eine au ergew hnlich gro e Auswahl an Rundtischlagern f r jeweils bevorzugte Bearbeitungsverfahren, Achstypen, Baugr en, Last- und Drehzahlbereiche. F r Anwendungen mit sehr hohen Drehzahlen sowie erh hten Anforderungen an die Kippsteifigkeit bietet Schaeffler neben den YRTC- auch noch die YRTS-Rundtischlager (S=Speed) an. Sie kommen z.B. in ultrapr zisen Fr s-, Schleif- und Verzahnungsmaschinen und in Rundtischen mit sehr hohen Drehzahlen zum Einsatz. Bei h chsten Drehzahlanforderungen stehen die zweireihigen INA Axial-Schr gkugellager der ZKLDF-Baureihe zur Verf gung. Ihr bevorzugter Einsatzbereich sind unter anderem Lagerungen mit hoher Einschaltdauer in Rundtischen mit Hauptspindelfunktion. Alle Baureihen k nnen mit integrierten Winkelmesssystemen ausger stet werden.
