Description

  • Wälzlager
  • Zweck der Erfindung sind Wälzlager herzustellen, die bei höchsten Drehzahlen der äußeren rotierenden Lagerschale durch die auftretenden Fliehkräfte keine Schmiermittelverluste haben.
  • Die bekannten seitlichen Abdeckungen von Wälzlagern sind im Außenring entweder durch Eindrücken der Blechscheiben 1 oder diese Scheiben 1 werden durch Springringe 2 (Abb. 1) befestigt. Beide Formen sind auf die Dauer bei hohen Fliehkräften nicht dicht.
  • In vorliegender Erfindung wird die absolute Schleuderdichtheit durch folgende Maßnahmen erreicht: Nach Abb. 2 werden die seitlichen Abdeckscheiben 3 durch Schweißen 4 oder bei geringerer Beanspruchung durch einen z.B.
  • heißhärtenden Metallkleber befestigt.
  • In Abb. 3 sind die seitlichen Abdeckscheiben 5 mit je einer längsgeteilten Lagerschale 7-7' aus einem Stück gefertigt und die Lagerschalenteile 7 und 7' durch Schweißen 4 verbunden.
  • In Abb. 4 ist ein Schräglager dargestellt, bei dem eine Abdeckscheibe 5 aus einem Stück mit dem Außenring 8 besteht, während die andere Scheibe 9 eingeschweißt 4 ist.
  • Abb. 5 stellt den gleichen Lagertyp mit Zentrierstufe lo dar, bei dem ein Teil des Außenringes 71 am Umfang mit dem Hauptteil 7 verschweißt 4 ist.
  • Diese M 5de ist auch.snnemf a-f andere Lagertypen z.B. Doppelrillenlager anzuwenden.
  • In Abb. 6 ist die schleuderdichte Ummantelung 11 eines Achsiallagers dargestellt, die mit einer Lagerscheibe 12 bei 4 verschweißt ist und die andere 13 berührungslos mit dem Teil 14 umfaßt
