In der DE 199 11 751 C1 ist eine Antriebseinrichtung für ein Walzgerüst mit zwei Arbeitswalzen beschreiben, wobei die Antriebseinrichtung ein Getriebe mit zwei Zahnwalzen aufweist, von denen je eine mit je einer Arbeitswalze des Walzgerüstes koppelbar ist. Die Zahnwalzen weisen eine unterschiedliche Zahl von Zähnen auf.In the DE 199 11 751 C1 is a drive device for a rolling stand with two work rolls describe, wherein the drive means comprises a gear with two toothed rollers, one of which is one each with a work roll of the rolling stand coupled. The toothed rollers have a different number of teeth.

Antriebseinrichtungen für Walzvorrichtungen, bestehend aus mindestens einem Motor und einem Getriebe sind weiterhin aus DE 699 121 , DE 924 983 , DE 44 08 289 A1 und DE 694 11 580 T2 bekannt.Drive devices for rolling devices, consisting of at least one engine and a transmission are still off DE 699 121 . DE 924 983 . DE 44 08 289 A1 and DE 694 11 580 T2 known.

Die bekannten Walzvorrichtungen sind für eine bestimmte Art ( Warmwalzen /Kaltwalzen ) und für vorher festgelegte Eigenschaften an das Walzgut ausgelegt. Anders ausgedrückt, die bestehenden Anlagen können nur bis zu einer vor längerer Zeit festgelegten Grenze belastet bzw. ausgenutzt werden.The known rolling devices are designed for a specific type (hot rolling / cold rolling) and for predetermined properties of the rolling stock. In other words, the existing facilities can only be charged or used up to a limit set a long time ago.

Um die Produktionsmengen zu erhöhen, die Qualität der-Erzeugnisse zu verbessern, geringere Enddicken erzeugen zu können sowie neue Erzeugnisse (Stahlsorten) produzieren zu können, müssen die Leistungen bzw. die Drehmomente und Abnahmen insbesondere an den ersten Walzgerüsten deutlich erhöht werden.In order to increase the production volumes, to improve the quality of the products, to be able to produce smaller final thicknesses and to produce new products (steel grades), it is necessary to significantly increase the performance or the torques and reductions, especially at the first rolling stands.

Bei vorhandenen Anlagen besteht das Problem, dass ein Umbau bzw. eine Modernisierung nur möglich ist, wenn die Stillstandszeiten minimal sind. Daher scheiden größere Fundamentarbeiten aus. Auf Grund der nicht veränderbaren Fundamente müssen auf gleicher Fläche wesentlich höhere Drehmomente bei Antriebsmotoren, Hauptgetriebe, Kammwalzengetriebe, den Zahnspindeln und den Arbeitswalzen übertragen werden. Durch die vorhandenen, nicht zu verändernden Fundamente ist der horizontale Abstand der Antriebsachse und der Abtriebsachse, die bei den bekannten Hauptgetrieben auf einer Ebene liegen (siehe Figuren 2 und 3) nicht zu verkleinern oder zu vergrößern.For existing systems, the problem is that a conversion or modernization is only possible if the downtime is minimal. Therefore, greater foundation work is eliminated. Due to the unchangeable foundations significantly higher torques must be transmitted on the same surface drive motors, main gear, pinion gear, the toothed spindles and the work rolls. Due to the existing, not to changing foundations, the horizontal distance of the drive axle and the output shaft, which lie in the known main gears on a plane (see FIGS. 2 and 3 ) not to reduce or enlarge.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Antriebsvorrichtung der eingangs beschriebenen Art derart zu verbessern, dass die oben aufgezeigten Nachteile / Probleme vermieden werden.The invention is therefore based on the object to improve a drive device of the type described above such that the above-mentioned disadvantages / problems are avoided.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Antriebsachse im Hauptgetriebe einstufig und die Antriebsachse mit einem, nach oben gerichteten, vertikalen Abstand zur Abtriebsachse und der Motor unit einem Zwischenrahmen Verbunden auf dem Fundament befestigt ausgebildet ist. Hierdurch bleibt der horizontale Abstand der Achsen gleich, der räumliche Abstand kann aber vergrößert werden, um beispielsweise größere Achsdurchmesser, größere Zahnraddurchmesser usw. zu berücksichtigen.This object is achieved in that the drive axle in the main gear single stage and the drive axle with an upwardly directed, vertical distance to the output shaft and the motor unit is formed an intermediate frame connected fixed on the foundation. As a result, the horizontal distance between the axes remains the same, but the spatial distance can be increased to take into account, for example, larger axle diameter, larger gear diameter, etc.

In einer Weiterbildung ist das Hauptgetriebe mehrstufig, d.h. mindestens zweistufig ausgebildet. In besonderen Anwendungsfällen sind auch drei- oder vierstufige Ausführungen möglich. Durch eine mehrstufige Ausbildung des Hauptgetriebes wird erreicht, dass der horizontale Abstand der Antriebs- und der Abtriebsachse vor und nach dem Umbau identisch angeordnet ist, auch wenn ein höheres Drehmomente übertragen wird.In a further development, the main transmission is multi-stage, i. formed at least two stages. In special applications, three- or four-stage versions are possible. Through a multi-stage design of the main gear is achieved that the horizontal distance of the drive and the output shaft is arranged identically before and after the conversion, even if a higher torques is transmitted.

Durch eine Erhöhung der Übersetzung gegenüber dem ursprünglichen Zustand kann unter Umständen sogar der Antriebsmotor beibehalten werden. Bei einem Kammwalzengetriebe ist eine Drehmomenterhöhung meist bauraumneutral über den Achsabstand möglich.By increasing the ratio to the original state, it may even be possible to maintain the drive motor. In a pinion gearbox, torque increase is usually possible in a space-neutral manner over the axial spacing.

Bei den Zahnspindeln können größere Durchmesser eingesetzt werden, da im Gerüst Arbeitswalzen mit einem größeren Durchmesser eingesetzt werden.Larger diameters can be used with the toothed spindles since work rolls with a larger diameter are used in the framework.

Die Gestaltung des Hauptgetriebes erfolgt derart, dass der horizontale Achsabstand identisch bleibt. Eine vertikale Verschiebung der Antriebachse nach oben ist möglich, da eine Versetzung des Antriebsmotors auf dem vorhandenen und nicht zu ändernden Fundament in vertikaler Richtung durch einen Zwischenrahmen auf einfache Weise erfolgen kann.The design of the main gear is such that the horizontal center distance remains identical. A vertical displacement of the drive shaft upwards is possible, since a displacement of the drive motor on the existing and unchangeable foundation in the vertical direction can be done by an intermediate frame in a simple manner.

Der Vorteil der erfindungsgemäßen Antriebsvorrichtung besteht darin, dass die Produktionsmengen erhöht, die Qualität des Walzgut verbessert, geringere Enddicken erzeugt und neue Erzeugnisse ( Stahlsorten ) produziert werden können.The advantage of the drive device according to the invention is that the production quantities can be increased, the quality of the rolling stock improved, lower final thicknesses produced and new products (steel grades) can be produced.

Gemäß der Erfindung können die bei der vorhandenen Walzvorrichtung eingesetzten Motoren weiter verwendet werden. Es können aber auch neue Motoren zum Einsatz gelangen.According to the invention, the motors used in the existing rolling apparatus can continue to be used. However, new engines can also be used.

Die vertikale Ausrichtung des Motors erfolgt in einer speziellen Ausführung durch Unterlegen. Daher sind aufwändige Fundamentarbeiten nicht notwendig.The vertical alignment of the motor is done in a special design by lining. Therefore, elaborate foundation work is not necessary.

In Fig. 1 sind in Draufsicht die Komponenten einer Walzvorrichtung W dargestellt. Von einem Motor M wird ein Drehmoment auf ein Hauptgetriebe HG übertragen. Dieses ist beispielsweise mittels einer Zwischenrohrkupplung ZRK mit einem Kammwalzengetriebe KWG verbunden. Von dort werden die Arbeitswalzen AW von einem Walzgerüst G über Zahngelenkspindel ZS angetrieben.In Fig. 1 the components of a rolling device W are shown in plan view. From a motor M, a torque is transmitted to a main transmission HG. This is connected for example by means of an intermediate pipe coupling ZRK with a pinion gearbox KWG. From there, the work rolls AW are driven by a rolling stand G via toothed spindle ZS.

In einem Abstand I sind parallel dazu weitere Antriebsvorrichtungen vorhanden, die weitere Walzgerüste G, die in einem Abstand g vom ersten Walzgerüst G aufgestellt sind, antreiben. Der Abstand g zwischen mehreren Walzgerüsten G und der Abstand I zwischen mehreren Antriebsvorrichtungen kann dabei gleich oder unterschiedlich sein.At a distance I further drive devices are parallel to this, the other rolling stands G, which are placed at a distance g from the first stand G drive. The distance g between a plurality of rolling stands G and the distance I between a plurality of drive devices may be the same or different.

Aus dem Stand der Technik ist bekannt, das Hauptgetriebe HG einstufig auszubilden. Wie in Figur 2 und Figur 3 zu sehen, weist ein bekanntes Hauptgetriebe HG eine Antriebswelle und eine Abtriebswelle auf die mittels eines vorhandenen Zahnradpaares verbunden sind. Das Hauptgetriebe HG ist auf einem Fundament F angeordnet.From the prior art is known to form the main transmission HG in one stage. As in FIG. 2 and FIG. 3 To see, a known main gear HG has a drive shaft and an output shaft which are connected by means of an existing gear pair. The main transmission HG is arranged on a foundation F.

Die Antriebsachse AN und die Abtriebsachse AB einer Walzvorrichtung W weisen sowohl einen horizontalen Abstand hA als auch einen vertikalen Abstand vA auf. Ausgehend von einem vorhandenen Fundament, welches auf Grund von Zeitvorgaben nicht baulich verändert werden kann, muss die Achse des Antriebsmotors nur in vertikaler Richtung angepasst werden.A fiction, according to Ausfürungsbeispiel is in FIG. 6 shown. The drive axis AN and the output axis AB of a rolling device W have both a horizontal distance hA and a vertical distance vA. Based on an existing foundation, which can not be structurally modified due to time constraints, the axis of the drive motor must be adapted only in the vertical direction.
