Description

Die Erfindung bezieht sich auf ein Stauchwalzwerk zum seitlichen Stauchen eines Metallstrangs mit einem Paar mit den Mittelachsen senkrecht angeordneten, gegeneinander anstellbaren Walzen, die mittels Gelenkwellen an einen Drehantrieb angeschlossen sind.The invention relates to an upsetting roll for lateral upsetting of a metal strand with a pair of vertically arranged with the center axes, against each other engageable rollers which are connected by means of propeller shafts to a rotary drive.

Derartige Stauchwalzwerke werden in erheblichem Umfang als Vertikalwalz- oder Stauchgerüste mit einem oder mehreren Querhäuptern oder Traversen ausgeführt.Such compression rolling mills are carried out to a considerable extent as vertical rolling or edger stands with one or more crossheads or trusses.

Aus der EP 1 606 067 B1 ist ein Stauchwalzwerk für den Warmbetrieb bekannt, das ein Paar mit ihren Mittelachsen senkrecht angeordneten, gegeneinander anstellbaren Walzen umfasst, die mittels Gelenkwellen an zumindest einen Drehantrieb angeschlossen sind. Dieses Stauchwalzwerk zeichnet sich dadurch aus, dass der Drehantrieb für die beiden Walzen unterhalb der Hüttenflur-Ebene ortsfest angeordnet und mit jeweils einem ortsfesten Getriebe jeweils mit der Gelenkwelle antriebsmäßig verbunden ist. Ausgehend von einem Drehantrieb, der aus einem schweren elektrischen Motor besteht, wird die Antriebskraft mittels einer waagrecht angeordneten, durchgehenden und drehgelagerten Antriebswelle und beidseitig abgezweigten Kegelradgetriebestufen auf die beiden gegenüber der Senkrechten unter einem spitzen Winkel geneigten Gelenkwellen übertragen, die ihrerseits ihre Drehbewegung in Gelenkwellenkopf-Aufnehmern über Gelenkwellenköpfe auf die Stauchwalzen übertragen. Das bekannte Stauchwalzwerk hat den Nachteil, dass es einen großen Bauraum einnimmt.From the EP 1 606 067 B1 For example, an upsetting mill for hot operation is known, which comprises a pair of vertically arranged, mutually engageable rollers with their center axes, which are connected by means of drive shafts to at least one rotary drive. This compression roll mill is characterized by the fact that the rotary drive for the two rolls below the hut floor level arranged stationary and is drivingly connected in each case with a stationary gear each with the propeller shaft. Starting from a rotary drive, which consists of a heavy electric motor, the driving force is transmitted by means of a horizontal, continuous and rotatably mounted drive shaft and beveled on both sides bevel gear stages on the two opposite the vertical inclined at an acute angle propeller shafts, which in turn their rotary motion in Gelenkwellenkopf- Transfer transducers to the swaging rollers via cardan shaft heads. The known compression roll mill has the disadvantage that it occupies a large space.

Es ist die Aufgabe der Erfindung, ein Stauchwalzwerk der eingangs genannten Art so zu verbessern, dass es einfacher aufgebaut ist.It is the object of the invention to improve an upset mill of the type mentioned so that it is simpler.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass die beiden Walzen über zusammen mit den Walzen verstellbare Getriebe und über jeweils mit einem der beiden Getriebe verbundene Gelenkwellen mit dem Drehantrieb verbunden sind, wobei die Gelenkwellen unter einem spitzen Winkel gegenüber der Horizontalen geneigt sind.According to the invention, this object is achieved in that the two rollers are connected together with the rollers adjustable gear and connected via one of the two gearbox drive shafts with the rotary drive, wherein the propeller shafts are inclined at an acute angle to the horizontal.

Ein Vorteil der Erfindung ist, dass die Stauchwalzen und die zugehörigen Getriebe in von einander getrennte Baueinheiten aufgelöst sind. Ein weiterer Vorteil dieser neuen Ausgestaltung besteht darin, dass die Drehbewegung unmittelbar von den über eine Synchronwelle mit einem einzigen Antriebsmotor verbundenen Übersetzungsgetrieben oder von den über jeweils einen eigenen Antriebsmotor angetriebenen Übersetzungsgetrieben auf die Gelenkwellen übertragen wird. Daher können diese unter einem spitzen Winkel zur Horizontalen angeordnet sein. Durch diesen Aufbau kann die sonst auf die geneigt gegenüber der Senkrechten stehenden Gelenkwellen entfallende Bauhöhe entfallen, und durch den erfindungsgemäßen Aufbau des Stauchwalzwerks wird gegenüber dem Stand der Technik eine kompaktere Bauweise ermöglicht.An advantage of the invention is that the compression rollers and the associated gear are resolved into separate units. Another advantage of this new embodiment is that the rotational movement is transmitted directly from the connected via a synchronous shaft with a single drive motor transmission gears or driven by their own drive motor gearboxes on the propeller shafts. Therefore, these can be arranged at an acute angle to the horizontal. By this structure, the otherwise attributable to the inclined standing with respect to the vertical drive shafts omitted height, and by the inventive design of the compression roll mill is compared to the prior art allows a more compact design.

Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen, der Beschreibung und den Zeichnungen.Advantageous developments of the invention will become apparent from the dependent claims, the description and the drawings.

Vorzugsweise umfasst der Drehantrieb zwei Antriebsmotoren, von denen ein jeder, insbesondere über ein Übersetzungsgetriebe, mit einer der beiden Gelenkwellen verbunden ist.Preferably, the rotary drive comprises two drive motors, each of which, in particular via a transmission gear, is connected to one of the two drive shafts.

Alternativ hierzu lässt sich ebenfalls mit Vorteil vorsehen, dass die beiden Gelenkwellen jeweils mit Getrieben verbunden sind und dass das zu einer der Gelenkwellen gehörige Getriebe über eine Synchronwelle mit dem Antriebsmotor für den gemeinsamen Antrieb der beiden Getriebe verbunden ist. In einer weiteren Alternative sind die beiden Gelenkwellen über ein gemeinsames Getriebe und eine sich an dieses anschließende Synchronwelle mit dem Antriebsmotor verbunden. Die Getriebe sind beispielsweise als Übersetzungsgetriebe und beispielsweise als Kammwalzgetriebe ausgebildet.Alternatively, it can also be advantageously provided that the two propeller shafts are each connected to gears and that the belonging to one of the propeller shaft transmission is connected via a synchronous shaft with the drive motor for the common drive of the two gearboxes. In another alternative, the two propeller shafts via a common transmission and connected to this subsequent synchronous shaft with the drive motor. The gearboxes are designed, for example, as a transmission gearbox and, for example, as a combed roller gearbox.

In einer vorteilhaften Ausgestaltung ist die Synchronwelle in einem Führungselement gelagert, durch das sie gegenüber dem Boden abgestützt wird.In an advantageous embodiment, the synchronous shaft is mounted in a guide element, by which it is supported relative to the ground.

Vorzugsweise ist der Drehantrieb unterhalb der Hüttenflur-Ebene angeordnet.Preferably, the rotary drive is arranged below the hut floor level.

In einer weiteren vorteilhaften Ausgestaltung ist vorgesehen, dass unterhalb der Hüttenflur-Ebene eine Medienkette gelagert ist, die mit den zwischen den Gelenkwellen und den Stauchwalzen angeordneten Getrieben verbunden ist und die zur Versorgung der Getriebe mit den für den Betrieb erforderlichen Medien, insbesondere mit einem Schmiermittel oder einem Kühlmittel, und mit elektrischer Spannung, insbesondere für Messgeräte, dient.In a further advantageous embodiment, it is provided that below the hut floor level, a media chain is mounted, which is connected to the arranged between the propeller shafts and the compression rollers gears and to supply the transmission with the necessary media for operation, in particular with a lubricant or a coolant, and with electrical voltage, in particular for measuring instruments, is used.

Von Vorteil ist es, wenn das Stauchwalzwerk einen Walzenständer mit zwei Querhäuptern und mehreren zwischen diesen angeordneten Holmen umfasst.It is advantageous if the compression roll comprises a roll stand with two transverse heads and a plurality of bars arranged between them.

Vorzugsweise nehmen die Querhäupter jeweils Walzenanstelleinrichtungen auf, die jeweils auf eine der beiden Stauchwalzen wirken.Preferably, the crossheads each take Walzenanstelleinrichtungen, each acting on one of the two compression rollers.

Mit Vorteil weisen die Querhäupter zumindest je einen Balancierzylinder zum Vorspannen der Walzeinrichtung und zur Durchführung von Verfahrbewegungen beim Walzenwechsel auf.Advantageously, the crossheads each have at least one balancing cylinder for pretensioning the rolling device and for carrying out movements when changing the rolls.

Vorteilhaft ist es auch, wenn auf den Holmen Laufbahnen zur Führung von Balanciertraversen, der Stauchwalzen und der Getriebe angeordnet sind.It is also advantageous if tracks are arranged on the rails for the management of Balanciertraversen, the compression rollers and the transmission.

Ein weiterer Vorteil besteht darin, dass an den Stauchwalzen nach unten gerichtete Walzenzapfen angeordnet sind, die über Formschluss mit einem Walzentreffer in dem zugehörigen Getriebe verbunden sind.A further advantage is that the roll-ups are arranged downwardly directed roll journals, the positive fit with a roller hit are connected in the associated gear.

Das erfindungsgemäße Stauchwalzwerk besteht beispielsweise aus einem Walzenständer mit zwei Querhäuptern oder Traversen und jeweils zwei oberen, zwei mittleren und zwei unteren Holmen. Die Querhäupter nehmen zumindest je eine Walzenanstelleinrichtung auf, die mechanisch, hydraulisch arbeitet oder aus einer Kombination beider Betätigungsweisen besteht. Die Walzenanstelleinrichtung wirkt auf die beiden Stauchwalzen und übt die Walzkraft aus, die erforderlich ist, um die seitlichen Ränder eines Metallstrangs zu stauchen.The compression roll mill according to the invention consists for example of a roll stand with two transverse heads or traverses and two upper, two middle and two lower bars. The Querhäupter take at least ever a Walzenanstelleinrichtung, which operates mechanically, hydraulically or consists of a combination of both modes of operation. The Walzenanstelleinrichtung acts on the two compression rollers and exerts the rolling force required to compress the lateral edges of a metal strand.

Die zwei Querhäupter nehmen zumindest je einen Balancierzylinder auf, der eine Ausbalancierung, d. h. ein nahezu spielfreies Verspannen der Walzeneinrichtung, durchführt.The two crossheads at least each take a Balancierzylinder on which a balance, d. H. a virtually backlash-free clamping of the roller device, performs.

Die Querhäupter sind durch die Holme verbunden, die Kräfte aus dem Walzprozess in allen drei Raumrichtungen aufnehmen. Zudem sind Laufbahnen auf den oberen und den unteren Holmen angeordnet, die die Balanciertraverse, die Stauchwalzen und die zugehörigen Getriebe führen. Die Laufbahnen können für bestimmte Anwendungszwecke geneigt sein. Ebenso können die Balancierzylinder und die Walzenanstelleinrichtung zur Erreichung der optimalen Krafteinstellung und für die Bewegungsübertragung geneigt angeordnet sein.The crossheads are connected by the spars, which absorb forces from the rolling process in all three spatial directions. In addition, tracks are arranged on the upper and lower spars, which guide the Balanciertraverse, the compression rollers and the associated gear. The raceways may be inclined for certain applications. Likewise, the balancing cylinder and the Walzenanstelleinrichtung may be inclined to achieve the optimum force adjustment and for the motion transmission.

Die Balanciertraverse ist mit dem Balancierzylinder verbunden. Sie ist hier auf Laufbahnen auf den oberen Holmen geführt und formschlüssig mit dem Stauchwalzensatz verbunden. Beim Stauchwalzenwechsel verbleiben die Balanciertraversen und die Getriebe im Stauchwalzwerk.The balance crossbar is connected to the balance cylinder. She is led here on careers on the upper spars and positively connected to the compression roller set. During the compression roll change, the balancing cross members and the gearboxes remain in the compression roll mill.

Der Stauchwalzensatz wird durch die Walzenanstellung an das Walzgut gedrückt und übt die Walzkraft aus. Die Stauchwalze ist mit einem nach unten gerichteten Walzenzapfen ausgestattet, der über Formschluss mit einem Walzentreffer im Getriebe verbunden ist und so das Drehmoment von dem Getriebe auf die Walze überträgt. Hier wird der Formschluss durch einen walzenseitigen Flachzapfen und entsprechende Flachstellen im Walzentreffer des Getriebes gebildet, die über Verschleißplatten geschützt sind.The compression roller set is pressed by the roller adjustment to the rolling stock and exerts the rolling force. The compression roller is equipped with a downwardly directed roll neck, which is connected via positive engagement with a roller hit in the transmission and so the torque from the transmission transfers to the roller. Here, the positive connection is formed by a roller-side flat pin and corresponding flats in the roller hit of the transmission, which are protected by wear plates.

Die Stauchwalzen werden auf Laufbahnen auf den oberen Holmen geführt. Die entsprechenden Führungen an den Stauchwalzen sind drehbar und erlauben einen Ausgleich von Positionsunterschieden der Stauchwalzen gegenüber den Positionen im kalibrierten Zustand. Dadurch werden Zwang und durch diesen verursachte Beschädigungen von Lagern vermieden.The compression rollers are guided on tracks on the upper spars. The corresponding guides on the compression rollers are rotatable and allow a compensation of positional differences of the compression rollers relative to the positions in the calibrated state. This avoids compulsion and damage to bearings caused by it.

Das Getriebe ist jeweils zweistufig mit Kegelradsätzen und Stirnradsätzen ausgeführt. Jedes Getriebe und jeder Walzentreffer der Stauchwalzen wird mit Vorteil auf Laufbahnen auf den gemäß der Erfindung zusätzlich zum Einsatz kommenden unteren Holmen geführt und lässt sich daher als einzelnes Modul in das Stauchwalzwerk einbauen. Die entsprechenden Führungen an den Getriebekästen sind drehbar und vermeiden dadurch Zwang in den Lagern und in der Verbindung zwischen der Stauchwalze und dem Getriebe. Beim Wechsel der Stauchwalzen können die Getriebe im Stauchwalzwerk verbleiben.The gearbox is designed in two stages with bevel gear sets and spur gear sets. Each gear and each roller hit the compression rollers is performed with advantage on careers on the invention according to the invention in addition to use lower spars and can therefore be installed as a single module in the compression roller. The corresponding guides on the gear boxes are rotatable, thereby avoiding forcing in the bearings and in the connection between the compression roller and the gearbox. When changing the compression rollers, the gear can remain in the compression roller.

Die Getriebe folgen der Anstellbewegung der Stauchwalzen durch den Formschluss. Die Verbindungsstelle ist beispielsweise mit einem Zentrierring ausgestattet, der es dem Getriebe erlaubt, exakt der Bewegung der Stauchwalze zu folgen.The gearboxes follow the adjustment movement of the edging rolls due to the positive connection. The connection point is equipped, for example, with a centering ring, which allows the transmission to follow exactly the movement of the compression roller.

Jedes Getriebe ist über eine Medienkette mit den für den Betrieb erforderlichen Medien und der elektrischen Versorgung verbunden. Die Versorgung der Balanciertraverse und der Stauchwalzen erfolgt über diese Medienkette.Each gearbox is connected via a media chain with the necessary media for operation and the electrical supply. The supply of the balancing crosshead and the compression rolls takes place via this media chain.

Jedes Getriebe ist über eine Gelenkwelle mit Längenausgleich über je einen seitlich angeordneten Antriebsmotor verbunden. Alternativ ist auch die Verwendung nur eines einzigen Antriebsmotors möglich. Die Drehmomentenverteilung erfolgt dann über zusätzliche Übersetzungsgetriebe. Antriebsseitig sind die zusätzlichen Übersetzungsgetriebe mit einer Synchronwelle verbunden. Die Gelenkwellen sind an der Abtriebsseite dieser Übersetzungsgetriebe angeordnet. Die Synchronwelle kann mehrteilig sein und über ein oder mehrere Lagergehäuse unterstützt werden.Each gearbox is connected via a cardan shaft with length compensation via a laterally arranged drive motor. Alternatively, the use of only a single drive motor is possible. The torque distribution then takes place via additional transmission gear. On the drive side, the additional transmission gear are connected to a synchronous shaft. The propeller shafts are arranged on the output side of this transmission gear. The synchronous shaft can be multi-part and can be supported via one or more bearing housings.

Durch die Auflösung des Stauchwalzwerks in eine Vielzahl von einzelnen Modulen ergeben sich gegenüber dem Stand der Technik eine verbesserte Wartung und Handhabung und eine geringere Fehleranfälligkeit. Konstruktive Änderungen lassen sich leicht durchführen. Erfindungswesentlich ist insbesondere die Modulbauweise der Stauchwalzenbalancierung, der Stauchwalzen und des Hauptantriebsgetriebes.The resolution of the compression roll mill in a plurality of individual modules resulting in improved maintenance and handling and a lower susceptibility to errors compared to the prior art. Constructive changes are easy to perform. Essential to the invention is in particular the modular design of the compression roll balancing, the compression rolls and the main drive gear.

Vorzugsweise sind die Getriebe mit seitlich angeordneten Schwingen auf den unteren Holmen gelagert, die ein Pendeln der Getriebe entsprechend der Bewegung der Stauchwalzentreffer erlauben. Hierbei sind die Abtriebsräder der Getriebe jeweils mit einem separaten Treffer zur Aufnahme des Walzenzapfens der Stauchwalzen ausgestattet. Die Treffer sind mit einem Außen- und Innenmehrkant zur Momentenübertragung ausgestattet. Vorzugsweise sind die Treffer mit mindestens einem Zentrierring ausgestattet, die das zugehörige Getriebe exakt der Bewegung der jeweiligen Stauchwalze folgen lassen.Preferably, the gears are mounted with laterally arranged wings on the lower spars, which allow a commuting of the gearbox according to the movement of the compression roller hits. Here, the output gears of the transmission are each equipped with a separate hit to accommodate the roll neck of the compression rollers. The hits are equipped with an external and internal polygon for torque transmission. Preferably, the hits are equipped with at least one centering ring, which can follow the associated gear exactly the movement of the respective compression roller.

Zusammengefasst bestehen die Vorteile der Erfindung darin, dass sich das Stauchwalzwerk einfacher warten und leichter handhaben lässt als ein herkömmliches Stauchwalzwerk. Das erfindungsgemäße Stauchwalzwerk baut kompakter als ein Stauchwalzwerk nach dem Stand der Technik.In summary, the advantages of the invention are that the compression roll mill is easier to maintain and easier to handle than a conventional compression roll mill. The compression roll mill according to the invention is more compact than a prior art compression roll mill.

Ein Stauchwalzwerk (Fig. 1) umfasst einen Rahmen 1 mit Querhäuptern 2, 3 und oberen, mittleren und unteren Holmen 4, 5 und 6. Zwischen den oberen Holmen 4 sind jeweils die oberen Lagergehäuse 7, 8 von Stauchwalzen 9, 10 auf Balanciertraversen 11, 12 aufgenommen. Die unteren Lagergehäuse 13, 14 der Stauchwalzen 9, 10 werden im Bereich der mittleren Holme 5 von den Balanciertraversen 11, 12 aufgenommen.An upsetting mill ( Fig. 1 ) comprises a frame 1 with transverse heads 2, 3 and upper, middle and lower bars 4, 5 and 6. Between the upper bars 4 respectively the upper bearing housings 7, 8 of compression rollers 9, 10 are accommodated on balancing beams 11, 12. The lower bearing housings 13, 14 of the compression rollers 9, 10 are received in the region of the central spars 5 of the balancing spars 11, 12.

Auf der Oberseite der oberen Holme 4 sind geneigte Fahrbahnen 15 angebracht, über die in an sich bekannter Weise die Stauchwalzen 9, 10, deren Lagergehäuse 13, 14 und die Balanciertraversen 11, 12 verfahren werden. Anstelleinrichtungen 17, 18, 19 und 20 drücken seitlich gegen die Lagergehäuse 13, 14 sowie die in ihnen gelagerten Stauchwalzen 9, 10, wodurch die Stauchwalzen 9, 10 ihrerseits gegen den zu walzenden Metallstrang angestellt werden. Auf der Oberseite der unteren Holme 6 sind Fahrbahnen, über die die Getriebe 27, 28 mittels Schwingen 16 verfahren werden. Zur Einstellung der genauen Lage der Stauchwalzen 9, 10 und zur Vermeidung von Losen sind zwischen den Anstellantrieben zusätzlich Balancierzylinder 21, 22 angeordnet, die mit ihren Kolbenstangen 23, 24 an den Balanciertraversen 11, 12 angreifen und Positionierungenauigkeiten der Anstelleinrichtungen 17 bis 20 ausgleichen.On the upper side of the upper spars 4 inclined roadways 15 are mounted on the compression rollers 9, 10, the bearing housing 13, 14 and the Balanciertraversen 11, 12 are moved in a conventional manner. Adjustment means 17, 18, 19 and 20 press laterally against the bearing housing 13, 14 and the compression rollers 9, 10 mounted in them, whereby the compression rollers 9, 10 are in turn employed against the metal strand to be rolled. On the top of the lower spars 6 are lanes over which the gear 27, 28 are moved by means of swing 16. To adjust the exact position of the compression rollers 9, 10 and to avoid lots additional Balancierzylinder 21, 22 are arranged between the Anstellantrieben, which attack with their piston rods 23, 24 on the Balanciertraversen 11, 12 and compensate for positioning inaccuracies of the Anstelleinrichtungen 17 to 20.

Die Stauchwalzen 9, 10 sind jeweils mit Walzenzapfen 25, 26 oder Walzentreffern ausgestattet, über die sie mit Getriebesätzen 27, 28 zusammenwirken, die ihr Antriebsmoment auf die Stauchwalzen 9, 10 übertragen. Die Getriebesätze 27, 28 umfassen jeweils Stirnradgetriebe mit schrägverzahnten Zahnrädern und Kegelradgetriebe; diese werden jeweils durch eine Gelenkwelle 29, 30 angetrieben. Die Gelenkwellen 29, 30 sind jeweils längen- und winkelverstellbar, so dass sie Verstellungen der Stauchwalzen 9, 10 in horizontaler Richtung mitvollziehen können, während sie antriebsseitig jeweils über (nicht dargestellte) Getriebe mit Antriebsmotoren 31, 32 verbunden bleiben. Eine Medienkette 33 stellt die Versorgung der Getriebesätze 27, 28 sowie anderer Bestandteile des Stauchwalzwerks mit elektrischer Energie sowie mit fluiden Medien sicher.The compression rollers 9, 10 are each with roll necks 25, 26 or roller hits equipped, over which they interact with gear sets 27, 28, which transmit their driving torque to the compression rollers 9, 10. The gear sets 27, 28 each comprise helical gears with helical gears and bevel gear; These are each driven by a propeller shaft 29, 30. The propeller shafts 29, 30 are each adjustable in length and angle, so that they can carry out adjustments of the compression rollers 9, 10 in the horizontal direction, while on the drive side via (not shown) transmission with drive motors 31, 32 remain connected. A media chain 33 ensures the supply of gear sets 27, 28 and other components of the compression roll with electrical energy and fluid media.

Alternativ zum Einsatz zweier Antriebsmotoren 31, 32 ist gemäß einer weiteren Ausführungsform der Erfindung (Fig. 2) lediglich ein einziger Antriebsmotor 34 vorgesehen, der über ein Übersetzungsgetriebe 35 unmittelbar die Gelenkwelle 30 antreibt, während die Gelenkwelle 29 über eine ein- oder mehrteilig ausgestaltete Synchronwelle 36 und ein Getriebe 37 von dem Antriebsmotor 34 angetrieben wird. Alternativ zu dieser Ausgestaltung lässt sich vorsehen, dass die beiden Gelenkwellen 29, 30 ein gemeinsames Getriebe 35 haben und dass die Gelenkwelle 29 lediglich über das Getriebe 37, beispielsweise ein Kammwalzgetriebe, mit der Synchronwelle 36 verbunden ist. Die Gelenkwelle 30 ist über ein beispielsweise ebenfalls als Kammwalzgetriebe ausgebildetes Getriebe 35 mit der Synchronwelle 36 sowie dem Antriebsmotor 34 verbunden. Die Synchronwelle 36 wird aus Gründen der Stabilität vorzugsweise in wenigstens einem Führungselement 38 drehbar gelagert.Alternatively to the use of two drive motors 31, 32, according to a further embodiment of the invention ( Fig. 2 ) only a single drive motor 34 is provided, which drives directly via a transmission gear 35, the propeller shaft 30, while the propeller shaft 29 is driven via a one or more parts configured synchronous shaft 36 and a transmission 37 of the drive motor 34. As an alternative to this embodiment, it can be provided that the two propeller shafts 29, 30 have a common transmission 35 and that the propeller shaft 29 is connected to the synchronizing shaft 36 only via the transmission 37, for example a comb-type gearbox. The propeller shaft 30 is connected via a, for example, also designed as Kammwalzgetriebe gear 35 with the synchronous shaft 36 and the drive motor 34. For reasons of stability, the synchronizing shaft 36 is preferably rotatably mounted in at least one guide element 38.

Durch die Ausgestaltung der Erfindung ist es gemäß beiden dargestellten Ausführungsformen möglich, die Bauhöhe des Bereichs unterhalb einer Hüttenebene 39 gegenüber dem Stand der Technik erheblich zu reduzieren, da der Kellerraum unterhalb der Hüttenebene 39 in der Höhe lediglich Raum für die Antriebsmotoren 31, 32 oder den einzelnen Antriebsmotor 34 und die schräg gelagerten Gelenkwellen 29, 30 benötigt.Due to the embodiment of the invention, it is possible according to both illustrated embodiments, the height of the area below a hut level 39 to reduce significantly compared to the prior art, since the basement below the hut level 39 in height only space for the drive motors 31, 32 or the single drive motor 34 and the obliquely mounted propeller shafts 29, 30 required.
