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

Beschreibungdescription
Zylindercylinder
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 3033230 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.From DE 3033230 C2 an impression cylinder is known, the axle journals are held in end shields. An actuator for the metered introduction of pressure forces in order to compensate for the cylinder deflection acts on the free ends of the axle journals protruding from the end shields.
Die US 4 913051 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.US 4 913051 A discloses a cylinder of a rotary printing press, wherein a jacket of the cylinder is mounted on a carrier by means of roller bearings. At the ends, a distance between the jacket and the carrier is fixed in the radial direction and cannot be changed by means of roller bearings. Additional rolling bearings with adjusting means for changing the distance between the jacket and the support are arranged between these rolling bearings.
Der Erfindung liegt die Aufgabe zugrunde, einen Zylinder zu schaffen.The invention has for its object to provide a cylinder.
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 advantages achievable with the invention consist in particular in that the setting force is introduced via the axis and via the bearings arranged between the jacket and the axis. This already results in a pipe bend when the cylinder is fitted, which corresponds to the tendency of the forme cylinder bend. The bending is adjusted 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 innenliegenden Stellantrieben eine verbesserte Biegesteifigkeit zur Folge.Due to the arrangement of a bearing with an actuator at the ends of the jacket, a weakening due to the space requirement of the actuator is only in the area of the ends of the Carrier or jacket necessary. In contrast to internal actuators, this results in improved bending stiffness.
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.Inner and outer bearings are placed within a common oil circuit, which means that no relubrication of the outer bearings is required. In addition, a permanent oil circulation between both ends of the impression cylinder leads to the dissipation of the heat from the rubber-coated cylinder jacket, which is caused by the flexing work 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 bearing points are housed within the pipe jacket results in a shorter axis overhang and a shorter overall length, which results in a cheaper installation option, even when retrofitting in existing machines.
Die Gestaltung der Achslagerung erleichtert den Ein- und Ausbau gegenüber bekannten Ausführungen.The design of the axle bearing 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 shown in the drawing and will be described in more detail below.

Der rotierbare Mantel 03 des Gegendruckzylinders 01 kommt auf seiner Innenfläche 29 mit einem Fluid, z. B. Öl von einem Schmiermittel- und Kühlkreislauf 31 in Verbindung. Der Schmiermittel-Kühlkreislauf 31 erstreckt sich von einem ersten Fluideinlass oder - auslass 32 im ersten hohlen Achszapfen 04 zu einem zweiten Fluideinlaß oder -auslaß im nicht dargestellten zweiten hohlen Achszapfen.The rotatable jacket 03 of the impression cylinder 01 comes on its inner surface 29 with a fluid, for.

The lubricant cooling circuit 31 extends from a first fluid inlet or outlet 32 in the first hollow journal 04 to a second fluid inlet or outlet in the second hollow journal, not shown.
In Strömungsrichtung von links nach rechts verlaufen beiderseitig des Arbeitszylinders 17 Axialbohrungen 33 und nachfolgend im Achszapfen 04 Radialbohrungen 34 (Fig. 2). Weiterhin wird das Fluid in einen Raum zwischen dem Träger 02 mit dem Durchmesser D; d und der Innenfläche 29 des Mantels 03 geführt.
