Description

Es ist bekannt, bei Walzwerken zum Aufbereiten von Ton oder anderen breiigen oder körnigen Massen an den Stirnseiten der Walzen Abschlußplatten anzubringen, die verhindern sollen, daß sich Walzgut an den Walzenenden durchquetscht, zwischen Walzenstuhl oder Walzenwange und den Walzen festsetzt und schließlich in die Walzenlager eindringt, also einen vorzeitigen Verschleiß ίο der Lager herbeiführt. Werden derartige Abschlußplatten fest angebracht, so unterliegen sie einem starken Verschleiß, der ein häufiges Auswechseln erfordert, welches selbst bei dem auch schon bekannten Einlegen auswechselbarer Platten in Herzstücke noch sehr unbequem und unvollkommen ist, da das kleinste Undichtwerden wieder den Ton in die Lager gelangen läßt.It is known in rolling mills for processing clay or other pulpy or to attach granular masses to the end faces of the rollers, which prevent should that rolling stock squeezes through at the roll ends, between the roll frame or roll cheek and the rolls sets and finally penetrates the roller bearings, i.e. premature wear ίο the camp brings about. If such end plates are firmly attached, so are subject they are subject to heavy wear and tear, which requires frequent replacement, even with the already known insertion exchangeable plates in frogs is still very uncomfortable and imperfect, since the slightest leak will again the Lets clay get into the camp.

Gegenstand der Erfindung ist nun eine Abao dichtung, bei welcher die Nachteile der bisher bekannten Walzenspaltabdichtungen dadurch vermieden werden, daß an den beiden Stirnseiten der einen Walze jedes Walzenpaares oder an der einen Stirnfläche der einen und der entgegengesetzten Stirnfläche der anderen Walze, zweckmäßig auswechselbar, je eine Scheibe aus Stahl o. dgl. angebracht wird, die, über den Walzenumfang allseitig vorragend und auf der in gleicher Ebene Hegenden Stirnfläche der Nachbarwalze gleitend, den Walzenspalt überdeckt. Diese mit den Walzen umlaufenden Abschlußplatten haben auch noch den besonderen Vorteil, daß sie durch Fliehkraft das Material stets abschleudern, wobei durch eine Abstreiferanordnung die Möglichkeit des Eindringens von Werkstoff zwischen Walzen und Walzenstuhl noch weiter verringert werden kann. j Die Zeichnung veranschaulicht ein Aus- i führungsbeispiel des Erfindungsgegenstandes, j und zwar zeigtThe invention is now an Abao seal in which the disadvantages of the previous known roll gap seals are avoided in that each pair of rolls on the two end faces of one roll or on one end face of the one and the opposite end face of the other roller, expediently interchangeable, each with a steel disc or the like attached that protrudes over the circumference of the roller on all sides and is on the same level Front surface of the neighboring roller sliding, covering the roller gap. This with the Rolls revolving end plates also have the particular advantage that they go through Centrifugal force always throw off the material, whereby the Possibility of penetration of material between the rollers and the roller frame even further can be reduced. j The drawing illustrates an i management example of the subject invention, j namely shows

Abb. ι eine Stirnansicht eines erfmdungs- ' gemäß ausgebildeten Walzenpaares und Abb. 2 einen wagerechten Schnitt durch dieses Walzenpaar und die Walzenwangen.Fig. Ι a front view of an inventive 'according to trained roller pair and Fig. 2 shows a horizontal section through this pair of rollers and the roller cheeks.

In den beiden Walzenwangen 1 sind in üblicher Weise die beiden Walzen 2 mittels Zapfen 3 und Lagerkörpern 4 gelagert. Die beiden einander gegenüberliegenden ■ Stirnflächen der Walzen 2 und 3 tragen je eine ringförmige Stahlscheibe 5, die den Walzenumfang allseitig überragen, auf der in gleicher Ebene liegenden Stirnfläche der Nachbarwalze gleiten und den Walzenspalt 6 überdecken. Die Stahlringe 5 sind zweckmäßig lösbar, beispielsweise mit Hilfe von Nieten o. dgl., befestigt. Sie könnten naturgemäß auch beide an den beiden Stirnflächen einer der Walzen sitzen.In the two roller cheeks 1, the two rollers 2 are in the usual way by means of Journal 3 and bearing bodies 4 supported. The two opposite faces of the rollers 2 and 3 each carry an annular steel disk 5, which surrounds the roller circumference protrude on all sides, on the face of the neighboring roller lying in the same plane slide and cover the nip 6. The steel rings 5 are expediently detachable, for example with the aid of rivets o. The like., attached. You could of course also both at the two end faces of one the rollers sit.

Am Umfang der Walzen sind zweckmäßig in üblicher Weise Abstreifer vorgesehen, so daß das von den Walzenumf ängen mitgenommene Walzgut abgestreift wird, bevor es in eine Lage gelangt, in der es in die Lager abfallen könnte. Die große Umfangsgeschwindigkeit der Ringe 5 bewirkt überdies ein Abschleudern etwa noch an ihren Umfangen anhaftender Stoffe.On the circumference of the rollers, scrapers are expediently provided in the usual way, see above that the rolled material entrained by the roll circumferences is stripped before it is in reaches a position where it could fall into the bearings. The great peripheral speed the rings 5 also causes a spinning off about even more clinging to their circumferences Fabrics.
