Description
Die Erfindung betrifft einen Extruder nach dem Oberbegriff des Anspruchs 1 und eine Schnecken-Welle für einen Extruder nach dem Oberbegriff des Anspruchs 4.The The invention relates to an extruder according to the preamble of the claim 1 and a screw shaft for an extruder after the Preamble of claim 4.
Derartige Extruder und die in ihnen eingesetzten Schnecken-Wellen der gattungsgemäßen Art sind allgemein bekannt und in der Praxis verbreitet.such Extruder and the worm shafts used in them the generic Species are well known and widely used in practice.

Der Erfindung liegt die Aufgabe zugrunde, einen Extruder und eine Schnecken-Welle für einen Extruder so auszugestalten, dass die Drehmoment-Belastung der Verzahnungs-Welle über ihre Länge vergleichmäßigt und damit eine besonders hohe Drehmoment-Übertragung möglich wird.Of the Invention is based on the object, an extruder and a screw shaft for an extruder in such a way that the torque load the toothing shaft uniformed over its length and thus a particularly high torque transmission possible becomes.
Diese Aufgabe wird bei einem Extruder der gattungsgemäßen Art durch die Merkmale im Kennzeichnungsteil des Anspruchs 1 und bei einer Schnecken-Welle der gattungsgemäßen Art durch die Merkmale im Kennzeichnungsteil des Anspruchs 7 gelöst. Der Kern der Erfindung liegt darin, dass einerseits die Drehmoment-Kopplung zwischen allen Behandlungs-Elementen und der mit einer Längs-Verzahnung versehenen Welle über deren volle Länge erfolgt, und dass die Drehmoment-Belastung pro Längeneinheit der Verzahnungs-Welle über ihre Länge vergleichmäßigt wird. Dadurch wird die insgesamt mögliche Drehmomentübertragung, d. h. die insgesamt mögliche Drehmomentbelastung der Rundum-Verzahnungen der Verzahnungs-Welle einerseits und der Behandlungs-Elemente andererseits ausgeglichen und damit in vollem Umfang ausnutzbar.These Task is in an extruder of the generic type Kind by the features in the characterizing part of claim 1 and in a worm shaft of the generic Art solved by the features in the characterizing part of claim 7. The core of the invention is that on the one hand the torque coupling between all treatment elements and the one with a longitudinal toothing provided shaft over its full length, and that the torque load per unit length of Gear shaft uniformed over its length becomes. This will reduce the total possible torque transfer, d. H. the total possible torque load of the all-round gears the gear shaft on the one hand and the treatment elements on the other balanced and thus fully exploitable.
