Abstract
Auswechselbare Druckwalze (1), mit einer inneren Lagerhülse (4, 4') und einer äußeren Hülse (2, 2'), dadurch gekennzeichnet, dass zwischen der inneren Lagerhülse (4, 4') und der äußeren Hülse (2, 2') ein ringförmiger Spalt (6, 6') ausgebildet ist und an gegenüberliegenden Endabschnitten ein Montagering (3, 3') zwischen der Lagerhülse (4, 4') und der äußeren Hülse (2, 2') eingefügt ist.Interchangeable pressure roller (1), with an inner bearing sleeve (4, 4 ') and an outer sleeve (2, 2'), characterized in that between the inner bearing sleeve (4, 4 ') and the outer sleeve (2, 2' ) an annular gap (6, 6 ') is formed and at opposite end portions of a mounting ring (3, 3') between the bearing sleeve (4, 4 ') and the outer sleeve (2, 2') is inserted.
Description
Die vorliegende Erfindung betrifft eine auswechselbare Druckwalze mit einer inneren Lagerhülse und einer äußeren Hülse.The The present invention relates to a replaceable pressure roller with an inner bearing sleeve and an outer Sleeve.
Die
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 is a replaceable To create a pressure roller, which has a high dimensional stability and has a high concentricity.
Diese Aufgabe wird mit einer auswechselbaren Druckwalze mit den Merkmalen des Anspruches 1 gelöst.These Task is with a replaceable pressure roller with the features of claim 1 solved.
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 between the inner bearing sleeve and the outer Sleeve formed an annular gap, wherein at opposite end portions a mounting ring between the bearing sleeve and the outer sleeve is inserted. This allows the pressure roller with low Dead weight can also be produced at large diameters, since the annular gap to a construction with low weight leads. The replaceable pressure roller can thereby at printing units be used, whose drives to a predetermined weight adjusted in terms of inertia of the pressure rollers are without problems due to a higher weight occur.
Für eine stabile Befestigung ist der Montagering vorzugweise zwischen der äußeren Hülse und/oder der inneren Lagerhülse klemmend gehalten, insbesondere mittels Presspassung. Dadurch können sowohl Radialkräfte als auch Torsionskräfte zwischen der äußeren Hülse und der inneren Lagerhülse übertragen werden. Alternativ oder zusätzlich kann der Montagering auch mit der inneren Lagerhülse und/oder der äußeren Hülse verklebt sein.For a stable attachment of the mounting ring is preferably between the outer sleeve and / or the inner Bearing sleeve held clamped, in particular by means of press fit. This allows both radial forces and torsional forces between the outer sleeve and the inner bearing sleeve transferred become. Alternatively or additionally, the mounting ring also with the inner bearing sleeve and / or the outer Sleeve glued.
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 a simple mounting of the pressure roller is the inner bearing sleeve made of an expandable plastic. This allows the pressure roller on a Bearing axis are raised, using compressed air by the plastic the bearing sleeve can be widened to this then of remove the journal.
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.Around to be able to produce the printing roll with low own weight, the outer sleeve is preferably made formed of an extruded aluminum tube. This can also be thin-walled be formed, for example, with a wall thickness between 1 up to 5 mm, preferably 2 to 4 mm. Also, the mounting ring may be off Be made of aluminum, so that the pressure roller has a low weight has.
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.Of the Mounting ring is preferably stepped and engages with a ring portion between the inner bearing sleeve and the outer sleeve. For fixing the position the outer sleeve and the inner bearing sleeve the mounting ring can thereby have a flange, the frontally for the bearing sleeve and the outer Sleeve forms a stop.
