Ein in der Figur linkes Ende der Messerwelle 2 ist mittels eines axial belastbaren radialen Lagers 7.1 - hier in Form eines Wälzlagers - in einem Lagerschaft 7 aufgenommen. Der Lagerschaft 7 dient der Lagerung des genannten linken Endes der Messerwelle 2 in einer bestimmungsgemäßen Lage. Hierunter wird eine Lage verstanden, in der die Messerwelle 2 ihre Funktion erfüllen kann und axial spielfrei aufgenommen ist.An in the figure left end of the
Der Lagerschaft weist einen radial expandierbaren Expansionsabschnitt 8 auf. In diesem Expansionsabschnitt 8 trägt der Lagerschaft 7 eine in der Weise elastisch verformbare Druckhülse 9, dass sich diese unter axialer Druckspannung radial ausdehnt. Diese radiale Ausdehnung wird dazu genutzt, den Lagerschaft an dessen Expansionsabschnitt 8 in einer Lagerbohrung 11 eines zweiten der genannten Lagerhebel 6 und 6', und zwar des Lagerhebels 6', zu fixieren.The bearing shaft has a radially
Die Druckhülse 9 ist auf einen der Messerwelle 2 abgewandten Absatz des Lagerschaftes 7 aufgeschoben und in der von der Messerwelle 2 weg weisenden Richtung an einer stirnseitig am Lagerschaft 7 befestigten Anschlagscheibe 10 axial angeschlagen. Der Querschnitt der Druckhülse 9 überbrückt einen axialen Abschnitt eines Ringraumes zwischen dem genannten Absatz des Lagerschaftes 7 und der diese aufnehmenden Lagerbohrung 11.The
An die der Messerwelle 2 zugewandte Stirnseite der Druckhülse 9 ist ein in den genannten Ringraum eingesetzter Druckring 12 angestellt. In der Nachbarschaft des Druckringes 12 ist der Lagerschaft 7 mit einer diametralen Ausnehmung 13 versehen, in welche ein Druckbalken 14 eingesetzt ist, der an die der Messerwelle 2 zugewandte Stirnseite des Druckringes 12 angestellt ist.At the
In einer zentralen Axialbohrung des in Richtung auf die Messerwelle 2 auf die diametrale Ausnehmung 13 folgenden Abschnittes des Lagerschaftes 7 ist ein mit einer Längsnut 15' versehner erster Stößel 15 geführt. Dieser ist mittels einer quer in den Lagerschaft 7 eingeschraubten und in die Längsnut 15' eingreifenden Führungsschraube 16 gegen Verdrehen gesichert. An einem der Messerwelle 2 abgewandten Ende des Stößes 15 bildet dieser einen Zapfen 15" aus, der in eine entsprechende Bohrung des Druckbalkens 14 eingreift und diesen trägt. Eine durch den Zapfen 15" am Stößel 15 ausgebildete Schulter ist in Anlage an dem Druckbalken 14.In a central axial bore of the following in the direction of the
Eine quer in den Lagerschaft 7 eingeschraubte Stellschraube 17 weist einen konischen Abschnitt auf und steht in diesem jedenfalls in der bestimmungsgemäßen Lage der Messerwelle in Kontakt mit einer an den Konuswinkel der Stellschraube 17 angepassten, schrägen und der Messerwelle 2 zugewandten Stirnfläche des Stößels 15.A screwed transversely into the
In der genannten zentralen Axialbohrung des Lagerschaftes 7 ist auf der der Messerwelle 2 zugewandten Seite des Lagerschaftes 7 ein mit einer Längsnut 18.2 versehener zweiter Stößel 18.1 geführt.
