Halterung für die umlaufenden Gegenmesser an Flügelrädern zur Fliehkraft—^r Zerkleinerung in Mahl- oder Zerspanungsgehäusen.Bracket for the rotating counter knife on impellers for centrifugal force— ^ r Comminution in grinding or machining housings.

Die Erfindung betrifft eine Halterung für die umlaufenden Gegenmesser an den Flügelrädern beispielsweise" in Messerring—Zerspanern, in denen Hackschnitzel zu mehr oder weniger flachen Holzteilphen aufgespant werden, wobei das Flügelrad die Hackschnitzel unter Einwirkung der Fliehkraft gegen einen Ring schleudert,' der mit nach innen weisenden Messern bestückt ist und vor diesen Messern jeweils Schlitze zum Durchtreten der Späne hat. In gleicher Weise können die umlaufenden Gegenmesser in Flügelrädern für Schlagkreizmühlen oder Schlägermühlen verwendet werden. Die Außenkante derartiger Flügelräder ist einem starken Verschleiß ausgesetzt und man hat sie deshalb schon verschiedentlich mit auswechselbaren Gegenmessern bestückt. Diese Gegenmesser wurden an der Peripherie des umlaufenden Flügelrades bzw. Schlagkreuzes angeschraubt. Das Auswechseln und Neueinstellen auf einen gleichmäßigen Flugkreis erforderte viel Zeit und damit einen langen Maschinenstillstand.The invention relates to a holder for the rotating counter knife to the Impellers, for example, "in knife ring hoggers, in which wood chips to be machined to more or less flat wooden parts, with the impeller the wood chips against a ring under the action of centrifugal force flings, 'which is equipped with inwardly pointing knives and in front of them Knives each have slots for the chips to pass through. In the same way the rotating counter knives can be used in impellers for spreading beater mills or beater mills can be used. The outer edge of such impellers is subject to severe wear and tear and has therefore been used on a number of occasions equipped with interchangeable counter knives. These counter knives were screwed onto the periphery of the rotating impeller or cross beater. Replacing and readjusting to an even flight circle required a lot of time and thus a long machine downtime.

Gegenstand der Erfindung ist die Halterung dieser Gegenmesser an einem leicht auszuwechselnden Messerträger, so daß das Auswechseln in der Maschine in kürzester Zeit erfolgen kann. Das Gegenmesser wird außerhalb der Maschine an diesem Messerträger befestigt Und vorzugsweise durch Paßstifte fertig auf den gewünschten Flugkreis eingestellt. Der Messerträger wird in eine Schwalbenschwanzführung an der Peripherie des Flügelrades eingeschoben und durch Druckfedern in Richtung der Zentrifugalkraft vorgespannt.The subject of the invention is the mounting of this counter knife on an easy one to be exchanged, so that the change in the machine in can be done in the shortest possible time. The counter knife is on outside of the machine attached to this knife carrier and preferably set to the desired flight circle with dowel pins. The knife carrier is in a dovetail guide inserted on the periphery of the impeller and supported by compression springs biased in the direction of centrifugal force.

Die Figur erläutert die Erfindung an einem Schemabeispiel näher: In dem Messerring 1 mit nach innen weisenden Zerspanermessern 2 läuft das Flügelrad 3 um. Das Gegenmesser 4 ist an dem Messerträger 5 angeschraubt, der mittels einer Schwalbenschwanzführung 6 in das Flügelrad 3 axial eingeschoben worden ist. Er wird mit einer oder mehreren-,Federn 7 beispielsweise über Kugeln 8 in Richtung der Fliehkraft nach-außen vorgespannt. Die Schwalbenschwanzführung 6 kann parallel oder spitzwinklig zu der Schneide des Gegenmessers 4 verlaufen, die im Falle eines achsparallelen Flügels geradlinig, im Falle eines schrägen Flügels jedoch entsprechend einer Ellipse gekrümmt ausgebildet ist. Anstelle der Kugel, 8 können beliebig andere Gleitstücke verwendet werden.The figure explains the invention in more detail using a schematic example: In the knife ring 1 with inwardly pointing chipper knives 2, the impeller 3 rotates. The counter knife 4 is screwed to the knife carrier 5, the pushed axially into the impeller 3 by means of a dovetail guide 6 has been. He is with one or more, springs 7 for example over Balls 8 biased outward in the direction of the centrifugal force. The dovetail guide 6 can be parallel or at an acute angle to the cutting edge of the counter knife 4 run in a straight line in the case of an axially parallel wing, in the case of an inclined wing, however, it is curved in accordance with an ellipse. Instead of the ball 8, any other sliding pieces can be used be used.
