Description

Die vorliegende Erfindung betrifft eine auswechselbare Druckwalze mit einer inneren Lagerhülse und einer äußeren Hülse.The present invention relates to a replaceable pressure roller having an inner bearing sleeve and an outer sleeve.

Die WO 2005/030487 offenbart eine auswechselbare Druckwalze, die einen mehrlagigen Aufbau besitzt. Eine innere Kernschicht besteht dabei aus Polyurethanschaum, der von einer Zinkschicht umgeben ist. Die Zinkschicht schafft eine Verbindung zu einer umgebenden Aluminiumhülse, die eine Druckschicht bildet und über eine Klebemittelschicht mit einer Polymerhülse verbunden ist. Ein solcher mehrschichtiger Aufbau ermöglicht zwar die Herstellung von Druckwalzen mit einem großen Durchmesser bei geringem Eigengewicht, allerdings ist die Herstellung vergleichsweise aufwendig. Zudem ist die Rundlaufgenauigkeit und die Maßhaltigkeit abhängig von dem Aufwand bei der Herstellung. Eine gewisse Elastizität des Kernmaterials führt jedoch zwangsläufig zu Ungenauigkeiten bei der Rundlaufgenauigkeit.The WO 2005/030487 discloses a replaceable pressure roller having a multilayer structure. An inner core layer consists of polyurethane foam, which is surrounded by a zinc layer. The zinc layer bonds to a surrounding aluminum sleeve that forms a print layer and is bonded to a polymer sleeve via an adhesive layer. Although such a multilayer construction allows the production of pressure rollers with a large diameter at low weight, but the production is relatively expensive. In addition, the concentricity and the dimensional accuracy depends on the effort in the production. However, a certain elasticity of the core material inevitably leads to inaccuracies in the concentricity.

Die EP 791 477 eine Walze für das Auftragen einer Flüssigkeit, wobei ein äußeres Metallrohr auf einer elastischen Zwischenschicht aus Kunststoff gelagert ist. Die Zwischenschicht ist wiederum auf einer inneren Hülse gehalten.The EP 791 477 a roller for applying a liquid, wherein an outer metal tube is mounted on a plastic elastic intermediate layer. The intermediate layer is in turn held on an inner sleeve.

Die EP 1 138 483 offenbart eine Hülse für Druckwalzen, bei der ein Mantelrohr mittels Buchsen beabstandet von einem dehnbaren Rohr gehalten ist. Zur Montage des Hülse auf einem Walzenkern sind zusätzliche Tragscheiben vorgesehen, die auf dem Walzenkern aufliegen und deren Bohrungen auf den Durchmesser des Walzenkerns angepasst sind.The EP 1 138 483 discloses a sleeve for pressure rollers in which a jacket tube is held by bushes spaced from a stretchable tube. For mounting the sleeve on a roll core additional support disks are provided, which rest on the roll core and the bores are adapted to the diameter of the roll core.

Es ist daher Aufgabe der vorliegenden Erfindung eine auswechselbare Druckwalze zu schaffen, die eine hohe Maßhaltigkeit und eine hohe Rundlaufgenauigkeit besitzt.It is therefore an object of the present invention to provide a replaceable pressure roller, which has a high dimensional stability and high concentricity.

Diese Aufgabe wird mit einer auswechselbaren Druckwalze mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with a replaceable pressure roller having the features of claim 1.

Erfindungsgemäß ist zwischen der inneren Lagerhülse und der äußeren Hülse ein ringförmiger Spalt ausgebildet, wobei an gegenüberliegenden Endabschnitten ein Montagering zwischen der Lagerhülse und der äußeren Hülse eingefügt ist. Dadurch kann die Druckwalze mit geringem Eigengewicht auch bei großen Durchmessern hergestellt werden, da der ringförmige Spalt zu einer Bauweise mit geringem Eigengewicht führt. Die auswechselbare Druckwalze kann dadurch bei Druckwerken eingesetzt werden, deren Antriebe auf ein vorbestimmtes Gewicht hinsichtlich der Masseträgheit der Druckwalzen eingestellt sind, ohne dass Probleme aufgrund eines höheren Gewichtes auftreten.According to the invention, an annular gap is formed between the inner bearing sleeve and the outer sleeve, wherein at opposite end portions a mounting ring between the bearing sleeve and the outer sleeve is inserted. As a result, the pressure roller can be produced with a low weight even with large diameters, since the annular gap leads to a design with low weight. The replaceable pressure roller can thereby be used in printing units whose drives are set to a predetermined weight in terms of inertia of the pressure rollers, without problems due to a higher weight occur.

Für eine stabile Befestigung ist der Montagering zwischen der äußeren Hülse und der inneren Lagerhülse klemmend mittels Presspassung gehalten. Dadurch können sowohl Radialkräfte als auch Torsionskräfte zwischen der äußeren Hülse und der inneren Lagerhülse übertragen werden. Zusätzlich kann der Montagering auch mit der inneren Lagerhülse und/oder der äußeren Hülse verklebt sein.For a stable attachment of the mounting ring between the outer sleeve and the inner bearing sleeve is clamped by means of press-fitting. As a result, both radial forces and torsional forces can be transmitted between the outer sleeve and the inner bearing sleeve. In addition, the mounting ring may also be glued to the inner bearing sleeve and / or the outer sleeve.

Für eine einfache Montage der Druckwalze besteht die innere Lagerhülse aus einem aufweitbaren Kunststoff. Dadurch kann die Druckwalze auf eine Lagerachse aufgezogen werden, wobei mittels Druckluft der Kunststoff der Lagerhülse aufgeweitet werden kann, um diese dann von dem Lagerzapfen abzuziehen.For easy installation of the pressure roller, the inner bearing sleeve consists of an expandable plastic. Thereby, the pressure roller can be mounted on a bearing axis, which can be expanded by means of compressed air, the plastic of the bearing sleeve, to then deduct them from the bearing pin.

Um die Druckwalze mit geringem Eigengewicht herstellen zu können, ist die äußere Hülse vorzugsweise aus einem extrudierten Aluminiumrohr gebildet. Dieses kann auch dünnwandig ausgebildet sein, beispielsweise mit einer Wandstärke zwischen 1 bis 5 mm, vorzugweise 2 bis 4 mm. Auch der Montagering kann aus Aluminium hergestellt sein, damit die Druckwalze ein geringes Eigengewicht besitzt.In order to produce the pressure roller with low weight, the outer sleeve is preferably formed from an extruded aluminum tube. This can also be formed thin-walled, for example, with a wall thickness between 1 to 5 mm, preferably 2 to 4 mm. Also, the mounting ring may be made of aluminum, so that the pressure roller has a low weight.

Der Montagering ist vorzugsweise gestuft ausgebildet und greift mit einem Ringabschnitt zwischen der inneren Lagerhülse und der äußeren Hülse ein. Zur Lagefixierung der äußeren Hülse und der inneren Lagerhülse kann der Montagering dabei einen Flanschabschnitt aufweisen, der stirnseitig für die Lagerhülse und die äußere Hülse einen Anschlag ausbildet.The mounting ring is preferably stepped and engages with a ring portion between the inner bearing sleeve and the outer sleeve. To fix the position of the outer sleeve and the inner bearing sleeve of the mounting ring can thereby Have a flange portion which forms an end face for the bearing sleeve and the outer sleeve a stop.

Die Erfindung wird nachfolgend anhand von zwei Ausführungsbeispielen mit Bezug auf die beigefügten Zeichnungen näher erläutert. Es zeigen:

Figuren 1 bis 4
mehrere Ansichten eines ersten Ausführungsbeispieles einer erfindungsgemäßen Druckwalze, und
Figuren 5 bis 8
mehrere Ansichten eines zweiten Ausführungsbeispieles einer erfindungsgemäßen Druckwalze.
The invention will be explained in more detail below with reference to two embodiments with reference to the accompanying drawings. Show it:
FIGS. 1 to 4
several views of a first embodiment of a pressure roller according to the invention, and
FIGS. 5 to 8
several views of a second embodiment of a pressure roller according to the invention.

Eine Druckwalze 1 umfasst eine äußere Hülse 2, die an gegenüberliegenden Endabschnitten an einem Montagering 3 bzw. 13 gehalten ist. Der Montagering 3 verbindet dabei die äußere Hülse 2 mit einer Lagerhülse 4 aus einem aufweitbaren Kunststoffmaterial.A pressure roller 1 comprises an outer sleeve 2, which is held at opposite end portions to a mounting ring 3 and 13, respectively. The mounting ring 3 connects the outer sleeve 2 with a bearing sleeve 4 made of an expandable plastic material.

Wie aus Figur 3 ersichtlich ist, umfasst jeder Montagering 3 bzw. 13 einen nach innen gerichteten Abschnitt 5 bzw. 15, der zwischen der äußeren Hülse 2 und der Lagerhülse 4 eingreift. Dieser Abschnitt ist klemmend an der Lagerhülse 4 und der äußeren Hülse 2 festgelegt, vorzugsweise mittels Presspassung. Der Montagering 3 ist dabei gestuft ausgebildet und greift in eine Aufnahme ein, die durch einen verjüngten Endabschnitt 7 an der äußeren Hülse 2 gebildet ist. In einem mittleren Bereich ist zwischen der äußeren Hülse 2 und der Lagerhülse 4 ein ringförmiger Spalt 6 ausgebildet.How out FIG. 3 it can be seen, each mounting ring 3 or 13 comprises an inwardly directed portion 5 and 15, which engages between the outer sleeve 2 and the bearing sleeve 4. This section is fixed by clamping to the bearing sleeve 4 and the outer sleeve 2, preferably by means of a press fit. The mounting ring 3 is stepped and engages in a receptacle which is formed by a tapered end portion 7 on the outer sleeve 2. In a central region, an annular gap 6 is formed between the outer sleeve 2 and the bearing sleeve 4.

Der Montagering 3 weist einen Flanschabschnitt 8 auf, der als stirnseitiger Anschlag für die äußere Hülse 2 wirkt. An dem Flanschabschnitt 8 ist ferner eine Stufe ausgebildet, die auch für die innere Lagerhülse 4 als Anschlag wirkt. An dem Montagering 3 kann ferner an einem Innenumfang ein Ring 11 festgelegt sein, der über ein oder mehrere Schrauben festlegbar ist, die in entsprechende radiale Bohrungen 12 eingedreht werden können.The mounting ring 3 has a flange 8, which acts as an end stop for the outer sleeve 2. At the flange portion 8, a step is further formed, which also acts as a stop for the inner bearing sleeve 4. On the mounting ring 3 may further be fixed to an inner circumference, a ring 11 which can be fixed by one or more screws, which can be screwed into corresponding radial bores 12.

Die Festlegung der äußeren Hülse 2 aus dem extrudierten Aluminiumrohr erfolgen vorzugsweise ausschließlich über die Presspassung mit dem Montagering 3 und 13. Es ist auch möglich, zusätzliche Bohrungen 9 und 10 an einer Aussparung vorzusehen, um dort über Befestigungsmittel die Hülse 2 mit dem Montagering 3 bzw. 13 zu fixieren.The determination of the outer sleeve 2 made of the extruded aluminum tube is preferably carried out exclusively via the interference fit with the mounting ring 3 and 13. It is also possible to provide additional holes 9 and 10 at a recess in order there via fastening means the sleeve 2 with the mounting ring 3 and 13 to fix.

In den Figuren 5 bis 8 ist eine weitere Ausführungsform einer Druckwalze dargestellt, bei der die gleiche Lagerhülse 4' wie bei dem ersten Ausführungsbeispiel eingesetzt wird, allerdings der Außendurchmesser größer ist, so dass auch ein größeres Druckbild durch die Druckwalze 1' erzeugt werden kann. Die Druckwalze 1' umfasst eine äußere Hülse 2' aus einem extrudierten Aluminiumrohr, das an gegenüberliegenden Endabschnitten weder über einen Montagering 3' an einer Lagerhülse 4' fixiert ist. Zwischen der Lagerhülse 4' und der äußeren Hülse 2' ist ein ringförmiger Spalt 6' ausgebildet, der jedoch deutlich größer als bei dem ersten Ausführungsbeispiel ist.In the FIGS. 5 to 8 is a further embodiment of a pressure roller shown, in which the same bearing sleeve 4 'is used as in the first embodiment, however, the outer diameter is larger, so that a larger print image by the pressure roller 1' can be generated. The pressure roller 1 'comprises an outer sleeve 2' of an extruded aluminum tube, which is fixed at opposite end portions neither via a mounting ring 3 'on a bearing sleeve 4'. Between the bearing sleeve 4 'and the outer sleeve 2', an annular gap 6 'is formed, which, however, is significantly larger than in the first embodiment.

Der Montagering 3' ist gestuft ausgebildet und greift mit einem inneren Abschnitt 5' zwischen die Lagerhülse 4' und die äußere Hülse 2' ein, wobei der Ringabschnitt 5' an einem äußeren Umfang der Lagerhülse 4' klemmend anliegt. An einer Außenseite greift der Montagering 3' an einem Endabschnitt 7' der äußeren Hülse 2' ein, wobei an einem Flanschabschnitt 8' ein Anschlag in axiale Richtung für die Hülse 2' ausgebildet ist.The mounting ring 3 'is stepped and engages with an inner portion 5' between the bearing sleeve 4 'and the outer sleeve 2', wherein the annular portion 5 'on an outer periphery of the bearing sleeve 4' is applied by clamping. On an outer side of the mounting ring 3 'engages an end portion 7' of the outer sleeve 2 ', wherein at a flange portion 8', a stop in the axial direction for the sleeve 2 'is formed.

Die Druckwalzen 1 und 1' können bei geringem Eigengewicht unterschiedliche Durchmesser aufweisen, so dass auch unterschiedlich große Druckbilder erzeugt werden können. Durch den ringförmigen Spalt und der Lagerhülse 4, 4' und der äußeren Hülse 2 bzw. 2' kann die Druckwalze 1 bzw. 1' mit geringem Eigengewicht hergestellt werden, wobei die äußere Hülse 2' vergleichsweise dünnwandig ausgebildet sein kann.The pressure rollers 1 and 1 'may have different diameters at low weight, so that also different sized print images can be generated. By the annular gap and the bearing sleeve 4, 4 'and the outer sleeve 2 and 2', the pressure roller 1 and 1 'are made with a low weight, wherein the outer sleeve 2' may be formed relatively thin-walled.
