Abstract

The invention relates to a cylinder in a rotary press, in particular, for interacting with a form cylinder for a gravure press. According to the invention, the cylinder is improved with regard to its variable adaptability by the provision of a linear drive located at the end of the cylinder between the fixed support and rotating outer surface. Said linear drive operates in a vertical radial direction upwards toward the inner ring of a roller bearing.

Description

Die Erfindung betrifft einen Zylinder gemäß dem Oberbegriff des Anspruches 1.The invention relates to a cylinder according to the preamble of claim 1.

Durch die DE 30 33 230 C2 ist ein Gegendruckzylinder bekannt, dessen Achszapfen in Lagerschilden gehalten sind. Auf die aus den Lagerschilden herausragenden freien Enden der Achszapfen wirkt dabei jeweils ein Stellorgan zur dosierten Einleitung von Druckkräften zwecks Kompensation der Zylinderdurchbiegung.By the DE 30 33 230 C2 is known a counter-pressure cylinder whose journal are held in end shields. In each case, an actuator for the metered introduction of compressive forces in order to compensate for the cylinder deflection acts on the protruding from the end shields free ends of the journal.

Die US 4 913 051 A offenbart einen Zylinder einer Rotationsdruckmaschine, wobei ein Mantel des Zylinders mittels Wälzlager auf einem Träger gelagert ist. An den Enden ist ein Abstand zwischen Mantel und Träger in radialer Richtung unveränderbar mittels Wälzlager festgelegt. Zwischen diesen Wälzlagern sind weitere Wälzlager mit Stellmitteln zum Verändern des Abstands zwischen Mantel und Träger angeordnet.The US 4,913,051 A discloses a cylinder of a rotary printing machine, wherein a jacket of the cylinder is mounted by means of rolling bearings on a support. At the ends of a distance between the shell and the carrier in the radial direction is fixed unchangeable by rolling bearings. Between these bearings further bearings are arranged with adjusting means for varying the distance between the shell and the carrier.

Die US 4 637 109 A offenbart einen Zylinder, dessen Mantel auf einer Achse rotierbar gelagert ist. An den beiden Enden sind zwischen Mantel und Achse in radialer Richtung unbewegliche Wälzlager, dazwischen mittels Exzenter radial verstellbare Lager angeordnet.The US 4 637 109 A discloses a cylinder whose shell is rotatably mounted on an axis. At the two ends immovable rolling bearings between shell and axis in the radial direction, interposed by means of eccentric radially adjustable bearings.

Der Erfindung liegt die Aufgabe zugrunde, einen Zylinder mit verbesserter Biegesteifigkeit zu schaffen.The invention has for its object to provide a cylinder with improved flexural rigidity.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst.The object is achieved by the features of claim 1.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, dass die Einleitung der Anstellkraft über die Achse und über die zwischen Mantel und Achse angeordneten Lager erfolgt. Dadurch ergibt sich beim Aufsetzen des Zylinders bereits eine Rohrbiegung, die der Tendenz der Formzylinderbiegung entspricht. Der Biegeangleich erfolgt über die äußeren Lager.The achievable with the present invention consist in particular in that the introduction of the contact force on the axis and via the arranged between the shell and axle bearing takes place. This already results when placing the cylinder a pipe bend that corresponds to the tendency of the forging cylinder bend. The bend adjustment takes place via the outer bearings.

Durch die Anordnung eines Lagers mit Stellantrieb an den Enden des Mantels wird eine Schwächung infolge des Raumbedarfs des Stellantriebs nur im Bereich der Enden des Trägers bzw. Mantels notwendig. Dies hat im Gegensatz zu innenliegendenStellantrieben eine verbesserte Biegesteifigkeit zur Folge.By arranging a bearing with actuator at the ends of the jacket is a weakening due to the space requirement of the actuator only in the region of the ends of the Carrier or coat necessary. This results in improved flexural rigidity unlike internal actuators.

Innen- und Außenlager sind innerhalb eines gemeinsamen Ölkreislaufs platziert, dadurch ist kein Nachschmieren der Außenlager erforderlich. Darüberhinaus führt ein permanenter Ölumlauf zwischen beiden Enden des Gegendruckzylinders zum Abführen der Wärme vom gummibeschichteten Zylindermantel, welche durch die Walkarbeit des Gummimantels entstanden ist.Internal and external bearings are placed within a common oil circuit, so no relubrication of the outer bearing is required. Moreover, a permanent oil circulation between both ends of the counter-pressure cylinder leads to dissipating the heat from the rubber-coated cylinder jacket, which has been created by the flexing of the rubber jacket.

Dadurch, dass alle Lagerstellen innerhalb des Rohrmantels untergebracht sind, ergibt sich ein kürzerer Achsüberstand und eine kürzere Gesamtlänge, dadurch entsteht eine günstigere Einbaumöglichkeit, auch bei Nachrüstung in bestehende Maschinen.The fact that all bearings are housed within the tubular jacket, resulting in a shorter Achsüberstand and a shorter overall length, this results in a cheaper installation option, even when retrofitted into existing machines.

Die Gestaltung der Achslagerung erleichtert den Ein- und Ausbau gegenüber bekannten Ausführungen.The design of the axle mounting facilitates installation and removal compared to known designs.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is illustrated in the drawing and will be described in more detail below.
