Description

Die vorgeschlagene Einrichtung bezieht sich auf das Lagern eines Zylinderpaares, insbesondere für Zylinder zum Bearbeiten von Bogen oder Bahnen aus Papier, Gewebe, Folie, Kunststoffen, Metallen o. dgl. mit mindestens zwei Lager je Zapfen der jeweils beteiligten Zylinder, wobei der gegenseitige Abstand der Zylinder einstellbar, jeweils eines der Lager eines Zylinderzapfens in einem Nebengehäuse angeordnet und dieses Nebengehäuse einer Druckeinrichtung ausgesetzt ist.The proposed device relates to the storage of a pair of cylinders, in particular for cylinders for processing sheets or sheets made of paper, fabric, film, plastics, metals or the like. With at least two bearings per pin of the cylinder involved, the mutual distance between the Adjustable cylinder, one of the bearings of a cylinder pin is arranged in a secondary housing and this secondary housing is exposed to a pressure device.

Eine Einrichtung auf diesem Gebiet ist beispielsweise aufgrund der DE-C 12 53 282 vorbekannt. Bei dieser Einrichtung handelt es sich jedoch um eine Einrichtung, mit der unerwünschtes Spiel unwirksam gemacht werden soll, nicht jedoch um eine Einrichtung, mit der Kräfte, die während des Arbeitsvorganges der beteiligten Zylinder auftreten, so beherrscht werden sollen, daß sich eine möglichst geringfügige und/oder beherrschbare Durchbiegung aller beteiligten Maschinenelemente und/oder Maschinenteile ergibt.A device in this area is known for example from DE-C 12 53 282. However, this device is a device with which undesirable play is to be rendered ineffective, but not a device with which forces which occur during the working process of the cylinders involved are to be controlled in such a way that the smallest possible and / or controllable deflection of all involved machine elements and / or machine parts results.

Aufgrund der DE-B 20 33 515 ist daneben eine Einrichtung bekanntgeworden, bei der die Zapfen eines einzigen Zylinders und damit der Zylinder selbst mit Hilfe von Druckmittelzylindern durchgebogen werden sollen. Hier wirken die beteiligten Druckmittelzylinder auf die axial außenliegenden Enden der Zapfen, wohingegen ein ortsfest angeordnetes Lager am axial innenliegenden Ende jedes Zylinderzapfens angeordnet ist. Demzufolge kann sich der hier beschriebene Zylinder aufgrund der auf ihn ausgeübten Biegekräfte an die anderweitig vorgegebene Durchbiegung eines anderen Zylinders anpassen. Daher wird hier nur der eine Zylinder durchgebogen, während der andere Zylinder unbeeinflußt bleibt.Due to DE-B 20 33 515 a device has also become known in which the pin of a single cylinder and thus the cylinder itself with the help of Pressure cylinders should be bent. Here, the pressure medium cylinders involved act on the axially outer ends of the pins, whereas a stationary bearing is arranged on the axially inner end of each cylinder pin. As a result, the cylinder described here can adapt to the otherwise predetermined deflection of another cylinder due to the bending forces exerted on it. Therefore only one cylinder is deflected here, while the other cylinder remains unaffected.

Daneben ist durch die DE-B 15 75 479 eine weitere Einrichtung vorbekannt, bei der jeweils zwei Lager je Zapfen eines beteiligten Zylinders angeordnet sind. Hier soll ein Walzenabstand genau eingestellt werden, weshalb auch jedes der beteiligten Lager in einem Nebengehäuse gelagert ist und alle Lager jedes Zylinderzapfens durch eine druckausübende Einrichtung derart aufeinandergedrückt werden, daß in den Lagern etwa vorhandenes Spiel beseitigt wird. Keines der Lager ist jedoch in dem jeweiligen Gestell, das die beiden Zylinder des Zylinderpaares trägt, unmittelbar gelagert. Darüber hinaus ist eine Verstellung des Abstandes der Achsen der beiden Zylinder recht unbequem, denn dazu müßte ein Keil ohne Zuhilfenahme irgendwelcher Einstellvorrichtungen entgegen der auf ihn wirkenden Reibungskräfte feinfühlig verstellt werden. Es erfordert jedoch einen hohen zeitlichen Aufwand, um diesen Keil genau positionieren zu können.In addition, DE-B 15 75 479 discloses a further device in which two bearings are arranged for each pin of a cylinder involved. Here, a roller distance should be set exactly, which is why each of the bearings involved is mounted in a secondary housing and all bearings of each cylinder journal are pressed together by a pressure-exerting device in such a way that any play in the bearings is eliminated. However, none of the bearings is directly supported in the respective frame that carries the two cylinders of the pair of cylinders. In addition, an adjustment of the distance between the axes of the two cylinders is quite uncomfortable, because a wedge would have to be adjusted sensitively against the frictional forces acting on it without the aid of any adjusting devices. However, it takes a lot of time to position this wedge exactly.

Aus der DE-A 20 34 490 ist eine Einrichtung vorbekannt, bei der zwei Zylinder je Zapfen zwei Lager enthalten. Beide Lager jedes Zapfens sitzen jedoch in einem Hilfsgehäuse. Wenn daher dieses Hilfsgehäuse mit Hilfe hydraulischer Zylinder in seiner Lage verstellt wird, dann werden beide Lager zusammen verstellt.From DE-A 20 34 490 a device is known in which two cylinders contain two bearings per pin. However, both bearings of each pin sit in an auxiliary housing. Therefore, if this auxiliary housing is adjusted in position with the help of hydraulic cylinders, then both bearings are adjusted together.

In der JP-A 60-238 005 wird vorgeschlagen, das sog. Hilfsgehäuse auf das sog. äußere Lager, d. h. dasjenige, das von dem zu lagernden Zylinder weiter entfernt ist als das andere, zu setzen. Dies ergibt jedoch andere Möglichkeiten der Einflußnahme auf Lagerung bzw. Biegung oder Beseitigung von Spiel als bei der vorliegenden Erfindung.In JP-A 60-238 005 it is proposed that the so-called auxiliary housing on the so-called outer bearing, i. H. to set the one that is further away from the cylinder to be stored than the other. However, this results in other possibilities for influencing storage or bending or elimination of play than in the present invention.

Die bereits genannte DE-A 12 53 282 läßt zwar auch Hilfsgehäuse an den inneren Lagern erkennen, führt diese inneren Lager jedoch nicht im Hauptgestell und macht zudem das Hauptgestell selbst einstellbar.The already mentioned DE-A 12 53 282 also shows auxiliary housings on the inner bearings, but does not guide these inner bearings in the main frame and also makes the main frame itself adjustable.

Es besteht daher die Aufgabe, eine Einrichtung der in Rede stehenden Art derart auszubilden, daß sie bequem bedienbar wird und weitestgehend auch während des Betriebes an variable oder variierende Betriebsweisen der beteiligten Zylinder angepaßt werden kann.It is therefore the task of designing a device of the type in question in such a way that it is easy to operate and can largely be adapted during operation to variable or varying modes of operation of the cylinders involved.

Diese Aufgabe wird mit Hilfe der beigefügten Patentansprüche gelöst.This object is achieved with the help of the appended claims.

Aufgrund der vorgeschlagenen Lösung wird es möglich, daß der Fluß der an der Biegung oder den Biegungen beteiligten Kräfte unmittelbar am Gestell der Maschine entlangfließt, so daß es innerhalb praktischer Grenzen zu keiner oder nur äußerst geringer Durchbiegung des Gestells kommt. Darüber hinaus ergeben sich zahlreiche Möglichkeiten zum Einstellen oder für das Verstellen der Durchbiegung der Zylinder oder der übrigen Maschinenteile, so daß es ermöglicht wird, die Durchbiegung der Zylinder innerhalb sehr weiter Grenzen zu wählen und zu beherrschen. Dazu gehört beispielsweise, daß die Biegung der Zylinder oder eine Biegung, die den während des Betriebes auf diese Zylinder wirkenden Kräften entgegengerichtet ist, auch während des Umlaufes der Zylinder, also während des laufenden Betriebes der Maschine, in der diese Zylinder eingebaut sind, gegebenenfalls selbsttätig oder aber wahlweise auch durch Eingreifen einer Bedienungsperson eingestellt oder nachgestellt werden können. Beispielsweise ist es möglich, die Biegung oder eine die Biegung aufhebende Gegenbiegung mit Hilfe eines regelbaren Programms, das auch automatisiert ablaufen kann, während des Betriebs mehr oder weniger stark variierend einzustellen, wobei der Druck des in den Druckmittelzylindern befindlichen Druckes nicht unbedingt zeitweise auf Null abfallen muß.The proposed solution makes it possible for the flow of the forces involved in the bend or bends to flow directly along the frame of the machine, so that there is no or only very slight deflection of the frame within practical limits. In addition, there are numerous possibilities for adjusting or adjusting the deflection of the cylinders or the other machine parts, so that it is possible to select and control the deflection of the cylinders within very wide limits. This includes, for example, the curvature of the cylinders or a curvature that affects those cylinders that operate during operation Forces are opposed, even during the rotation of the cylinders, that is, during the ongoing operation of the machine in which these cylinders are installed, if necessary automatically or alternatively can also be adjusted or adjusted by the intervention of an operator. For example, it is possible to adjust the bend or a counter-bend that eliminates the bend with the aid of a controllable program, which can also run automatically, to a greater or lesser extent during operation, the pressure of the pressure in the pressure medium cylinders not necessarily occasionally dropping to zero got to.

In Weiterbildung des Grundgedankens ist es möglich, daß das axial zu dem jeweiligen Zylinder hin angeordnete Nebengehäuse der Druckeinrichtung ausgesetzt ist. Außerdem wird vorgeschlagen, daß die stärker tragenden sogenannten Hauptlager des jeweiligen Zylinderzapfens axial zu den Außenseiten des Zylinders hin angeordnet sind und daß zwischen den jeweils einander zugeordneten Nebengehäusen Druckmittelzylinder oder verstellbare Spannschlösser angeordnet sind. Außerdem kann zwischen einem Nebengehäuse und dem Gestell ein verstellbarer Anschlag oder ein weiterer Druckmittelzylinder angeordnet sein. Die dabei beteiligten Druckmittelzylinder können Metallbalgzylinder sein. Ferner kann die Abstützung einander zugehöriger Nebengehäuse gegenüber dem Gestell und die gegenseitige Abstützung dieser Nebengehäuse jeweils verschiedenen Seiten des jeweils zugehörigen Zylinderzapfens zugeordnet sein. Ferner können die in jedem Druckmittelzylinder anstehenden Drücke wahlweise entweder für mindestens einen Druckmittelzylinder jeweils einzeln oder für mindestens zwei Druckmittelzylinder gemeinsam eingestellt, gesteuert oder geregelt werden.In a further development of the basic idea, it is possible for the auxiliary housing which is arranged axially towards the respective cylinder to be exposed to the pressure device. It is also proposed that the stronger bearing so-called main bearings of the respective cylinder journal are arranged axially towards the outside of the cylinder and that pressure medium cylinders or adjustable turnbuckles are arranged between the respectively associated secondary housings. In addition, an adjustable stop or another pressure medium cylinder can be arranged between an auxiliary housing and the frame. The pressure medium cylinders involved can be metal bellows cylinders. Furthermore, the support of associated secondary housings with respect to the frame and the mutual support of these secondary housings can each be assigned to different sides of the respectively associated cylinder journal. Furthermore, the pressures present in each pressure medium cylinder can either be for at least one pressure medium cylinder can be adjusted, controlled or regulated individually or for at least two pressure medium cylinders.

Anhand zweier in den beigefügten Figuren schematisch abgebildeter Ausführungsbeispiele wird die vorgeschlagene Einrichtung näher erläutert. In den Figuren sind im vorliegenden Zusammenhang nicht wesentliche Maschinenteile wegen einer übersichtlicheren Darstellungsweise nicht dargestellt. Die nicht dargestellten Teile sind dem Fachmann jedoch hinreichend bekannt. Außerdem wird darauf hingewiesen, daß die Ausführungsbeispiele in verschiedener Weise abgeändert werden können, ohne den der Einrichtung zugrundeliegenden Grundgedanken zu verlassen.The proposed device is explained in more detail with reference to two exemplary embodiments shown schematically in the attached figures. In the present context, non-essential machine parts are not shown in the figures because of a clearer representation. However, the parts which are not shown are sufficiently known to the person skilled in the art. It is also pointed out that the exemplary embodiments can be modified in various ways without departing from the basic idea underlying the device.

Eine Bahn 1 aus Papier, Folie, Gewebe, Kunststoff, Metall o. dgl. oder aber auch ein derartiger Bogen läuft zwischen zwei Zylindern 2 und 3 hindurch, wobei sie/er bei dieser Gelegenheit bearbeitet wird. Der Bearbeitungsvorgang kann beispielweise darin bestehen, daß die Bahn 1 oder der Bogen bedruckt wird. In diesem Fall müßte der eine der beiden Zylinder ein solcher Zylinder sein, der imstande ist, ein Druckmuster auf die Bahn 1 aufzubringen, und der andere Zylinder ein solcher, der imstande ist, die dabei auftretenden Kräfte oder Gegenkräfte aufzunehmen. Die Zylinder können aber auch beispielsweise solche Zylinder sein, die zum Längs- und Querschneiden oder Längs- oder Querperforieren benutzt werden können. Auch jegliche andere Zylinder, mit denen die Bahn 1 oder der Bogen bearbeitet werden können, sind möglich, was jedoch voraussetzt, daß die beteiligten Zylinder dem jeweils vorliegenden Bearbeitungsvorgang entsprechend ausgestaltet oder ausgerüstet sind.The individual figures mean:

A web 1 made of paper, foil, fabric, plastic, metal or the like, or else such a sheet runs between two cylinders 2 and 3, whereby he / she is processed on this occasion. The processing operation can consist, for example, in that the web 1 or the sheet is printed. In this case, one of the two cylinders would have to be one which is able to apply a printing pattern to the web 1, and the other cylinder which is capable of absorbing the forces or counterforces that occur in the process. However, the cylinders can also be, for example, cylinders which can be used for longitudinal and transverse cutting or longitudinal or transverse perforation. Any other cylinder with which the web 1 or the sheet can be processed is also possible, which, however, presupposes that the cylinders involved are designed or equipped in accordance with the respective processing operation.

Damit die während des Bearbeitungsvorganges auf die beteiligten Zylinder wirkenden Kräfte aufgefangen werden können, ist jeder Zylinder mit Zylinderzapfen versehen. Diese Zylinderzapfen sind an jedem stirnseitigen Ende des jeweiligen Zylinders angebracht. Die Lagerung der Zylinderzapfen ist für jeden Zapfen im wesentlichen die gleiche. Die Zapfen der beiden beteiligten Zylinder 2 und 3 wirken jedoch in ähnlicher Weise miteinander zusammen wie die beteiligten Zylinder selbst. Da die Lagerung der Zapfen an beiden Stirnseiten im wesentlichen die gleiche ist - die Zylinderzapfen können gegebenenfalls über die Lagerung hinaus verlängert werden, um Zahnräder oder dgl. für den Antrieb der beiden Zylinder aufzunehmen, falls dies erforderlich sein sollte - braucht zum Verständnis der vorgeschlagenen Einrichtung nur die Lagerung an einer Stirnseite der beteiligten Zylinder beschrieben zu werden. Die Lagerung an der anderen Stirnseite ist im wesentlichen die gleiche.So that the forces acting on the cylinders involved during the machining process can be absorbed, each cylinder is provided with cylinder pins. These cylinder pins are attached to each end of the respective cylinder. The storage of the cylinder pin is essentially that for each pin same. However, the pins of the two cylinders 2 and 3 involved interact in a similar manner to one another as the cylinders themselves. Since the bearing of the pins on both end faces is essentially the same - the cylinder pins can be extended beyond the bearing, if necessary, by gears or The like for the drive of the two cylinders, if this should be necessary - in order to understand the proposed device, only the mounting on one end face of the cylinders involved needs to be described. The storage on the other end face is essentially the same.

Der Zylinder 2 ist mit einem Zapfen 4 und Zylinder 3 mit einem Zapfen 5 versehen. Der Zapfen 4 ist mit Hilfe eines Lagers 6 und der Zapfen 5 mit Hilfe eines Lagers 7 in dem Gestell 8 der Einrichtung unmittelbar und Kräfte hauptsächlich aufnehmend gelagert. Die Lager 6 und 7 befinden sich an demjenigen Ende des Zapfens 4 oder 5, das dem Zylinder 2 oder 3 jeweils abgewendet ist. An denjenigen Enden der Zapfen 4 und 5, die den Zylindern 2 und 3 zugewandt sind, ist ein Lager 9 für den Zapfen 4 und ein Lager 10 für den Zapfen 5 vorgesehen. Da die Lager 9 und 10 dem Zylinder 2 bzw. 3 zugewandt sind, spricht man hier auch gern von sogenannten inneren Lagern im Gegensatz zu den sogenannten äußeren Lagern 6 und 7. Es ist dabei auch möglich, daß die inneren Lager stärkere Kräfte als die äußeren oder daß beide Arten von Lagern gleichgroße Kräfte aufnehmen.The cylinder 2 is provided with a pin 4 and cylinder 3 with a pin 5. The pin 4 is mounted with the aid of a bearing 6 and the pin 5 with the aid of a bearing 7 in the frame 8 of the device directly and mainly absorbing forces. The bearings 6 and 7 are located at that end of the pin 4 or 5 which faces away from the cylinder 2 or 3, respectively. A bearing 9 for the pin 4 and a bearing 10 for the pin 5 are provided at those ends of the pins 4 and 5 which face the cylinders 2 and 3. Since the bearings 9 and 10 face the cylinders 2 and 3, one speaks of what are known as inner bearings, in contrast to the so-called outer bearings 6 and 7. It is also possible that the inner bearings have stronger forces than the outer ones or that both types of bearings absorb equally large forces.

Lager 9 wird durch ein erstes Teil 11 eines Nebengehäuses, Lager 10 durch ein zweites Teil 12 des Nebengehäuses umgeben/gehalten. Die Ausbildung des Nebengehäuses 11/12 geht insbesondere aus Fig. 2 hervor. Die Teile 11 und 12 des Nebengehäuses sind vorzugsweise in entsprechenden senkrechten, am Gestell befindlichen Führungen vertikal verschiebbar gelagert. Diese Führungen sind in den Figuren wegen besserer Anschaulichkeit nicht dargestellt. Zwischen dem Gestell 8 und dem Teil 12 des Nebengehäuses ist ein erster Druckmittelzylinder 13, also eine druckausübende Einrichtung, vorzugsweise in einer Ausnehmung des Gestells 8 befindlich, angeordnet. Zwischen dem zweiten Teil 12 und dem ersten Teil 11 ist ein zweiter Druckmittelzylinder 14 und zwischen ersten Teil 11 und Gestell 8 ein dritter Druckmittelzylinder 15 angeordnet. Insbesondere dadurch, daß der zweite Druckmittelzylinder ebenso wie alle anderen Druckmittelzylinder ein Metallbalgzylinder sein kann, sind die Teile 11 und 12 durch ihn untereinander verbunden, denn Metallbalgzylinder werden üblicherweise mit den durch sie bewegten Maschinenteilen verschraubt. Wie aus Fig. 2 zu ersehen ist, sind die Druckmittelzylinder 13 und 15 auf der einen Seite der Geraden 16, die die geometrische Mitte 18 von Zylinder 3 und die geometrische Mitte 17 von Zylinder 2 und damit die zugehörigen Zylinderzapfen 4 und 5 verbindet, angeordnet (in Fig. 2 links), wohingegen der zweite Druckmittelzylinder 14 auf der entgegengesetzten Seite (in Fig. 2 rechts) angeordnet ist. Auf diese Weise können Kräfte, die beispielsweise von einem dieser Druckmittelzylinder ausgeübt werden, derart durch die Lager 9 und 10 geleitet werden, daß etwa zwischen den Zylinderzapfen und den jeweiligen Lagern vorhandenes Spiel unwirksam gemacht werden kann.Bearing 9 is surrounded / held by a first part 11 of an auxiliary housing, bearing 10 by a second part 12 of the auxiliary housing. The design of the secondary housing 11/12 is particularly apparent from Fig. 2. The parts 11 and 12 of the secondary housing are preferably vertically displaceably mounted in corresponding vertical guides located on the frame. These guides are not shown in the figures for better clarity. A first pressure medium cylinder 13, that is to say a pressure-exerting device, preferably located in a recess in the frame 8, is arranged between the frame 8 and the part 12 of the secondary housing. A second pressure medium cylinder 14 is arranged between the second part 12 and the first part 11 and a third pressure medium cylinder 15 is arranged between the first part 11 and frame 8. In particular, because the second pressure medium cylinder, like all other pressure medium cylinders, can be a metal bellows cylinder, the parts 11 and 12 are connected to one another by it, since metal bellows cylinders are usually screwed to the machine parts moved by them. As can be seen from FIG. 2, the pressure medium cylinders 13 and 15 are arranged on one side of the straight line 16, which connects the geometric center 18 of cylinder 3 and the geometric center 17 of cylinder 2 and thus the associated cylinder pins 4 and 5 (on the left in FIG. 2), whereas the second pressure cylinder 14 is arranged on the opposite side (on the right in FIG. 2). In this way, forces which are exerted, for example, by one of these pressure medium cylinders can be passed through the bearings 9 and 10 such that approximately between the Cylinder pin and the respective bearings existing game can be made ineffective.

Die in den Druckmittelzylindern herrschenden Drücke werden vorzugsweise hydraulisch erzeugt, weshalb die vorgeschlagene Einrichtung durch einen entsprechenden Druckerzeuger mit Steuerung-, Einstell- oder Regelungseinheit ergänzt wird. Das zugehörige Druckmittel, insbesondere Hydrauliköl, kann entweder jedem Druckmittelzylinder einzeln oder allen Druckmittelzylindern gemeinsam zugeführt und auch je nach Wahl einzeln oder in Gruppen zusammengefaßt eingestellt, gesteuert oder geregelt werden. Es ist daher möglich, die Zylinder sowohl einzeln mit Druckmittel als auch mehrere oder gar alle Druckmittelzylinder einander strömungstechnisch parallelliegend mit Druckmittel zu versorgen.The pressures prevailing in the pressure medium cylinders are preferably generated hydraulically, which is why the proposed device is supplemented by a corresponding pressure generator with a control, setting or regulating unit. The associated pressure medium, in particular hydraulic oil, can either be supplied to each pressure medium cylinder individually or all pressure medium cylinders together and can also be set, controlled or regulated individually or in groups, depending on the choice. It is therefore possible to supply the cylinders both individually with pressure medium as well as several or even all of the pressure medium cylinders in a fluidically parallel manner with pressure medium.

Das zugehörige Druckmittel kann auch mit Hilfe eines entsprechend gesteuerten oder gespeicherten Programms sowohl in seiner Menge als auch in seinem Druck gesteuert oder geregelt zugeführt werden. Diese Steuerung kann abhängig sein von den verschiedenen Betriebszuständen der Maschine, wie z. B. verschiedenen Laufgeschwindigkeiten. Es ist aber auch möglich, den Druck entsprechend der Laufgeschwindigkeit während des Betriebes zu modulieren. Die Druckmittelzylinder können beispielsweise aus sogenannten Metallbalgzylindern bestehen oder anderen Zylindern, die die Verwendung relativ hoher Drücke gestatten. Dadurch, daß den Druckmittelzylindern verschiedene Drücke wahlweise zugeführt werden können und jeder in den Figuren dargestellte Druckmittelzylinder auch durch jeweils mehrere dieser Druckmittelzylinder ersetzt werden kann, kann der auf das Nebengehäuse 11/12 ausgeübte Druck oder können die auf dieses Nebengehäuse ausgeübten Kräfte und deren Angriffspunkte in weiten Grenzen verändert werden. Beispielsweise ist es möglich, dem ersten Druckmittelzylinder 13 relativ hohen Druck zuzuführen, so daß er relativ hohe Kräfte entwickelt, und dem zweiten Druckmittelzylinder 14 und/oder dem dritten Druckmittelzylinder 15 relativ kleine Drücke zuzuführen, so daß diese nur relativ kleine Kräfte entwickeln können. Es ist aber ebenfalls möglich, jeden Druckmittelzylinder mit einem anderen Druck arbeiten zu lassen, so daß jeder Druckmittelzylinder eine andere Kraft oder andere Kräfte hervorzubringen in der Lage ist. Auf diese Weise kann der zwischen den Zylindern 2 und 3 befindliche Abstand feinfühlig und innerhalb weiter Grenzen je nach Wunsch eingestellt werden. Damit können auch die auf die sogenannten Hilfslager 9 und 10 wirkenden Kräfte in weiten Grenzen eingestellt, vorgewählt oder während des Betriebes der Einrichtung je nach Wunsch auch laufend verstellt werden. Während dieser Zeit bleiben die sogenannten Hauptlager 6 und 7 in dem Gestell 8 gelagert, ohne daß an ihrer Lagerung direkt etwas geändert würde. Selbstverständlich wirken von den Druckmittelzylindern aufgebrachte Reaktionskräfte auch auf diese Lager, was hingegen nur ein zusätzlicher Nebeneffekt sein kann.The associated pressure medium can also be supplied or controlled in terms of both its quantity and its pressure with the aid of a correspondingly controlled or stored program. This control can depend on the various operating states of the machine, such as. B. different running speeds. But it is also possible to modulate the pressure according to the running speed during operation. The pressure medium cylinders can, for example, consist of so-called metal bellows cylinders or other cylinders that allow the use of relatively high pressures. Characterized in that different pressures can be optionally supplied to the pressure medium cylinders and each pressure medium cylinder shown in the figures can also be replaced by several of these pressure medium cylinders, the pressure exerted on the secondary housing 11/12 or the forces exerted on this secondary housing and their points of application can be varied within wide limits. For example, it is possible to supply the first pressure medium cylinder 13 with relatively high pressure, so that it develops relatively high forces, and to supply the second pressure medium cylinder 14 and / or the third pressure medium cylinder 15 with relatively low pressures, so that these can only develop relatively small forces. However, it is also possible to have each pressure medium cylinder work with a different pressure, so that each pressure medium cylinder is able to produce a different force or forces. In this way, the distance between the cylinders 2 and 3 can be adjusted sensitively and within wide limits as desired. The forces acting on the so-called auxiliary bearings 9 and 10 can thus also be set within wide limits, preselected or continuously adjusted during operation of the device as desired. During this time, the so-called main bearings 6 and 7 remain stored in the frame 8 without anything directly changing their storage. Of course, reaction forces exerted by the pressure medium cylinders also act on these bearings, which, however, can only be an additional side effect.

Neben den in Fig. 2 dargestellten drei Druckmittelzylindern können unter Vergrößerung des Aufwandes auch mehrere Druckmittelzylinder zweckentsprechend an geeigneten Stellen angeordnet werden. Es ist hingegen unter Verringerung des Aufwandes aber ebenfalls möglich, nur einen Druckmittelzylinder vorzusehen und beispielsweise den zweiten Druckmittelzylinder 14 durch mindestens ein mechanisches Spannschloß 19 und den dritten Druckmittelzylinder 15 durch mindestens einen mechanisch verstellbaren Anschlag 22 zu ersetzen. Das Spannschloß 19 wird mit Hilfe von Gelenken 20 und 21 mit den Teilen 11 und 12 des Nebengehäuses in üblicher Weise verbunden. In diesem Fall bleibt jedoch mindestens ein Druckmittelzylinder 13 je Zapfenpaar der beteiligten Zylinder auch bei dem Ausführungsbeispiel nach Fig. 4 in der Einrichtung, so daß es auch hier möglich wird, während des Betriebes, d. h. während des Drehens der Zylinder 2 und 3, unterschiedliche, einander abwechselnde oder variierende Kräfte je nach Wahl aufzubringen. Das Ausführungsbeispiel nach Fig. 4 ist beispielsweise nichts anderes als ein Sonderfall des Ausführungsbeispiels nach Fig. 2, wenn die Einrichtung einerseits preiswerter, andererseits jedoch nicht so weitgehend variierbar wie in dem Beispiel nach Fig. 2 gestaltet werden soll. Zum Einstellen, Steuern oder Regeln ist eine Stell- oder Regelvorrichtung 23 vorgesehen, der über eine Leitung 24 und eine Pumpe 25 Druckmittel, wie beispielsweise Hydrauliköl zugeführt wird. Im Falle einer Regelung ist ein Sensor 26 mit der Regeleinrichtung über Leitung 27 ebenfalls verbunden. Beispielsweise signalisiert der Sensor 26 die Durchbiegung der Zylinder 2 und/oder 3 und veranlaßt die Regeleinrichtung, entsprechende Drücke den Druckmittelzylindern 13 bis 15 über Leitungen 28 bis 31 zuzuführen. Teileliste 1 Bahn 23 Stellvorrichtung 2 Zylinder 24 Leitung 3 Zylinder 25 Pumpe 4 Zapfen 26 Sensor 5 Zapfen 27 Leitung 6 Lager 28 Leitung 7 Lager 29 Leitung 8 Gestell 30 Leitung 9 Lager 31 Leitung 10 Lager 11 Nebengehäuse, erster Teil 12 Nebengehäuse, zweiter Teil 13 erster Druckmittelzylinder 14 zweiter Druckmittelzylinder 15 dritter Druckmittelzylinder 16 Gerade 17 geometrische Mitte 18 geometrische Mitte 19 Spannschloß 20 Gelenk 21 Gelenk 22 Anschlag In addition to the three pressure medium cylinders shown in FIG. 2, a plurality of pressure medium cylinders can also be suitably used, with an increase in complexity Positions. However, it is also possible, while reducing the effort, to provide only one pressure medium cylinder and, for example, to replace the second pressure medium cylinder 14 with at least one mechanical turnbuckle 19 and the third pressure medium cylinder 15 with at least one mechanically adjustable stop 22. The turnbuckle 19 is connected by means of joints 20 and 21 to the parts 11 and 12 of the secondary housing in the usual way. In this case, however, at least one pressure medium cylinder 13 per pair of pins of the cylinders involved also remains in the device in the exemplary embodiment according to FIG. 4, so that it is also possible here during operation, ie during the rotation of cylinders 2 and 3, different, to apply alternating or varying forces depending on the choice. The exemplary embodiment according to FIG. 4 is, for example, nothing other than a special case of the exemplary embodiment according to FIG. 2, if the device is to be made cheaper on the one hand, but on the other hand is not to be varied as widely as in the example according to FIG. 2. An adjusting or regulating device 23 is provided for setting, controlling or regulating, to which pressure medium, such as hydraulic oil, is supplied via a line 24 and a pump 25. In the case of control, a sensor 26 is also connected to the control device via line 27. For example, the sensor 26 signals the deflection of the cylinders 2 and / or 3 and causes the control device to supply corresponding pressures to the pressure medium cylinders 13 to 15 via lines 28 to 31.
