Description

Universalwalzwerk. Es sind Universalwalzwerke bekannt, bei welchen der Antrieb der Walzen von einem zentral gelagerten Getriebekörper aus erfolgt. Diese Vorrichtungen haben einen sehr verwickelten Bau mit zahlreichen Getrieberädern und einen entsprechend schlechten Wirkungsgrad. Die Erfindung betrifft eine neue, beispielsweise für das Herunterwalzen von Rohren gut geeigneteAusführungsform eines derartigen Universalwalzwerkes, welche sich durch große Einfachheit und Übersichtlichkeit auszeichnet.Universal rolling mill. There are universal rolling mills known in which the rollers are driven by a centrally mounted gear unit. These devices are very intricate in construction with numerous gears and a correspondingly poor efficiency. The invention relates to a new, An embodiment of a well suited for rolling down pipes, for example such universal rolling mill, which is characterized by great simplicity and clarity excels.

Nach der Erfindung wird der zentral angeordnete Getriebekörper mit einem Hyperbelradkranz versehen, und dieser kämmt unmittelbar mit Hyperbelrädern der Walzenachsen. Es erfolgt also ein unmittelbarer Antrieb der Walzenachsen durch den -zentralen Getriebekörper unter Verwendung einer überraschend geringen Zähnezahl.According to the invention, the centrally arranged gear body is with provided with a hyperbolic wheel rim, and this meshes directly with hyperbolic wheels of the roller axles. So there is a direct drive of the roller axles the central gear body using a surprisingly small number of teeth.

Um in an sich bekannter Weise zwei benachbarte Walzensätze mit einem gemein Samen Antrieb zu versehen, wird ein mit zwei Hyperbelradkränzen versehener Getriebekörper zentral zwischen den beiden Walzensätzen angeordnet. Sämtliche Walzen beider Sätze erhalten dann unmittelbaren Antrieb, und zwar können dabei die beiden Walzensätze beliebig gegeneinander versetzt angeordnet sein. Infolge der einfachen Gesamtanordnung sind die Arbeitsstellen leichter zugänglich, so daß Störungen in einfacherer Weise zu beseitigen sind, und es lassen sich schließlich Führungen für die Arbeitsstücke wesentlich besser anbringen als bei den bekannten Universalwalzwerken.To in a known manner two adjacent sets of rollers with one Common to provide seed drive becomes a twin hyperbolic wheel rim Gear body arranged centrally between the two sets of rollers. All the rollers both sentences then receive direct drive, and both can Roll sets can be arranged offset from one another as required. As a result of the simple Overall arrangement, the jobs are more accessible, so that disturbances in Easier ways to eliminate, and it can eventually be guides for Attach the work pieces much better than with the known universal rolling mills.

In der Zeichnung ist eine Ausführungsform der Vorrichtung dargestellt. Es zeigen Abb. i einen Längsschnitt, Abb. 2 einen Querschnitt. Die Abbildungen zeigen zwei Walzensätze, deren Walzena bzw. b gegeneinander um 45' versetzt sind. Der zwischen den beiden Walzensätzen angeordnete gemeinsame Antrieb besteht aus dem zentral gelagerten Getriebekörper c mit zwei Hyperbelradkränzen d und e für den unmittelbaren Eingriff der Räder f der Walzenachsen. Ein auf der Welle r angeordnetes Antriebsrads greift in einen auf dem Getriebekörper c angeordneten Zahnkranz g ein. Beim Umlauf des Getriebekörpers werden sämtliche Walzen unmittelbar angetrieben, und zwar ist es gleichgültig, um welchen Winkel die beiden Walzensätze gegeneinander versetzt sind. In dem Gehäuse lassen sich, wie Abb. i zeigt, in einfacher Weise gute Führungen k bzw. i anordnen. Die Walzen sind leicht zugänglich, da sie durch Abnahme der Deckel k bzw. m freigelegt werden können.In the drawing, an embodiment of the device is shown. Fig. 1 shows a longitudinal section, Fig. 2 shows a cross section. The figures show two sets of rollers, the rollers a and b of which are offset from one another by 45 '. The common drive arranged between the two roller sets consists of the centrally mounted gear body c with two hyperbel wheel rims d and e for the direct engagement of the wheels f of the roller axles. A drive wheel arranged on the shaft r engages in a toothed ring g arranged on the gear body c. When the gear body rotates, all of the rollers are driven directly, regardless of the angle by which the two sets of rollers are offset from one another. As Fig. I shows, good guides k and i can be arranged in the housing in a simple manner. The rollers are easily accessible because they can be exposed by removing the cover k or m.
