Description

Die Erfindung betrifft eine Walze gemäß dem Oberbegriff der Ansprüche 1 und 11.The invention relates to a roller according to the preamble of claims 1 and 11.

Durch die EP 0 607 283 B1 ist eine Walze mit Mitteln zum axialen Bewegen des Walzenmantels bekannt, wobei eine Drehbewegung in eine axiale Hubbewegung umgewandelt wird. Dies geschieht dadurch, daß zwischen der Walze und im Walzeninneren befindlichen zylindrischen Elementen mittels eines Getriebes eine Differenzdrehzahl erzeugt wird, wodurch unter Verwendung einer Nockeneinheit eine Hubbewegung des Walzenmantels entsteht.From EP 0 607 283 B1, a roller with means for axially moving the roll mantle is known, wherein a rotary motion is converted into an axial stroke movement. This is achieved in that a differential speed is generated by means of a gear between the roller and located inside the roller cylindrical elements, whereby a stroke movement of the roll shell is formed using a cam unit.

Eine Walze 01, z. B. Reibwalze 01 eines Farbwerkes einer Rotationsdruckmaschine besteht aus einem Walzenmantel 02, welcher beidseitig jeweils mit einem ringförmigen Flansch 03 verschlossen ist. Jeder Flansch 03 nimmt in seiner zentrischen Bohrung 04 eine seitengestellfest sowie verdrehfest gelagerte Achse 06 auf. Zwischen Achse 06 und Bohrung 04 befindet sich ein Lager, z. B. Wälzlager 07, welches auf seinen Innenring 08 in axialer Hubrichtung A um einen definierten Betrag, z. B. eine axiale Hublänge h, verschieblich ist.A roller 01, z. B. Reibwalze 01 of an inking unit of a rotary printing machine consists of a roll shell 02, which is closed on both sides each with an annular flange 03. Each flange 03 takes in its central bore 04 on a side frame fixed and rotationally mounted axis 06. Between axis 06 and bore 04 is a camp, z. B. Rolling 07, which on its inner ring 08 in the axial stroke direction A by a defined amount, z. B. an axial stroke length h, is displaceable.

Innerhalb des Walzenmantels 02 und in unmittelbarer Nähe des Flansches 03 ist ein Getriebe 09 angeordnet, welches ein auf der Achse 06 mittels Lager, z. B. Kugellager 11 drehbar sowie um einen Betrag e zur Rotationsachse 12 der Reibwalze 01 exzentrisch gelagertes erstes Zahnrad 13 mit einer Rotationsachse 24 aufweist. Eine Außenverzahnung 14 des Zahnrades 13 ist mit einem am Inneren 16 des Walzenmantels 02 fest angeordneten, eine Innenverzahnung 17 aufweisenden zweiten Zahnrad 18 des Getriebes 09 in Eingriff. Das erste Zahnrad 13 weist etwa die 0,9-fache Anzahl von Zähnen des zweiten Zahnrades 18 auf.Within the roll shell 02 and in the immediate vicinity of the flange 03, a gear 09 is arranged, which is a on the axis 06 by means of bearings, for. B. ball bearing 11 rotatably and by an amount e to the axis of rotation 12 of the friction roller 01 eccentrically mounted first gear 13 having a rotation axis 24. An external toothing 14 of the gear 13 is arranged with a fixed to the interior 16 of the roll shell 02, an internal toothing 17 having second gear 18 of the Gear 09 in engagement. The first gear 13 has about 0.9 times the number of teeth of the second gear 18.

Weiterhin besitzt das erste Zahnrad 13 auf seiner flanschabgewandten Flanke zwei, jedoch vorzugsweise mehrere, z. B. vier, aus der Flanke in axialer Richtung herausragende und voneinander beabstandete Mitnehmer, z. B. Stehbolzen 20, 21, 22, 23. Die Stehbolzen 20 bis 23 bilden einen ersten Teil einer zweiteiligen Kupplung 26. Sie greifen formschlüssig in Bohrungen 27 bis 30 eines auf der Achse 06 drehbar gelagerten zweiten Teils der Kupplung 26 ein. Das zweite Teil der Kupplung 26 besteht aus einem auf der Achse 06 mittels Lager, z. B. Kugellager 32 gelagerten Antriebsteils 33 als Träger eines Innenringes 34 eines Wälzlagers, z. B. Kugellagers 36.Furthermore, the first gear 13 has on its flanschabgewandten flank two, but preferably several, z. B. four, protruding from the flank in the axial direction and spaced apart driver, z. The stud bolts 20 to 23 form a first part of a two-part clutch 26. They engage positively in bores 27 to 30 of a rotatably mounted on the axis 06 second part of the clutch 26 a. The second part of the coupling 26 consists of a on the axis 06 by means of bearings, for. B. ball bearing 32 mounted drive part 33 as a support of an inner ring 34 of a rolling bearing, z. B. ball bearings 36.

Eine Rotationsachse 37 des Kugellagers 36 verläuft in einem spitzen Winkel α von 5° bis 15° zur Rotationsachse 12 der Reibwalze 01. Das schräg angeordnete Kugellager 36 dient als Hubgetriebe zur Erzeugung des axialen Hubes der Reibwalze 01. Dieser wird dadurch bewirkt, daß ein Außenring 38 des Kugellagers 36 über ein Gelenk 39 mit dem Inneren 16 des Walzenmantels 02 formschlüssig verbunden ist.A rotational axis 37 of the ball bearing 36 extends at an acute angle α of 5 ° to 15 ° to the axis of rotation 12 of the friction roller 01. The obliquely arranged ball bearing 36 serves as a lifting gear for generating the axial stroke of the friction roller 01. This is caused by an outer ring 38 of the ball bearing 36 is positively connected via a hinge 39 with the interior 16 of the roll shell 02.

Das Gelenk 39 besteht aus einer Koppel 41, deren Enden 42; 43 jeweils als Gelenke 44; 46 ausgebildet sind.The hinge 39 consists of a coupling 41, the ends 42; 43 each as joints 44; 46 are formed.

Das am Außenring 38 des Kugellagers 36 angeordnete erste Kugelgelenk 44 ist über seine Kugelpfanne in Richtung Rotationsachse 37 des Kugellagers 36 hin- und herverschiebbar angeordnet (Fig. 2). Dies kann dadurch geschehen, daß eine außenringnahe Seite des ersten Gelenkes 44 mit Führungswülsten in radial verlaufenden Nuten des Außenringes 38 verschiebbar und arretierbar in Wirkverbindung sind - in der Zeichnung nicht dargestellt.The first ball joint 44 arranged on the outer ring 38 of the ball bearing 36 is arranged back and forth via its ball socket in the direction of the rotation axis 37 of the ball bearing 36 (FIG. 2). This can be done by an outer ring near side of the first joint 44 with Führungswülsten in radially extending grooves of the outer ring 38 are displaceable and lockable in operative connection - not shown in the drawing.

Durch diese Maßnahme ist es möglich, die in Fig. 1 gezeigte Hublänge h zu verändern, insbesondere gemäß Fig. 2 zu verkürzen.By this measure, it is possible to change the stroke length h shown in FIG. 1, in particular according to FIG. 2 shorten.

Der Durchmesser D jeder Bohrung 27 bis 30 entspricht mindestens dem Durchmesser d jedes Stehbolzens 20 bis 23 zuzüglich des zweifachen Betrages e der Exzentrizität eines Teiles 47 der Achse 06.The diameter D of each bore 27 to 30 corresponds to at least the diameter d of each stud 20 to 23 plus twice the amount e of the eccentricity of a portion 47 of the axis 06th

Die Reibwalze 01 arbeitet wie folgt:The friction roller 01 operates as follows:

Der auf der fest eingespannten Achse 06 umlaufende Walzenmantel 02 wird mittels Friktion von einer anderen, nicht dargestellten Walze, z. B. einer Farb- oder Feuchtauftragwalze angetrieben. Das auf dem exzentrischen Teil 47 der Achse 06 frei drehbar gelagerte erste Zahnrad 13 kämmt mit der Innenverzahnung 17 des zweiten Zahnrades 18. Infolge einer unterschiedlichen Zähneanzahl, z. B. 60 zu 66 erhält das erste Zahnrad 13 eine größere Drehzahl n1 gegenüber einer Drehzahl n2 des Walzenmantels 02 mit dem zweiten Zahnrad 18.The on the fixedly clamped axis 06 rotating roll shell 02 is by means of friction of another, not shown roller, for. B. a paint or dampening roller driven. The freely rotatably mounted on the eccentric portion 47 of the axis 06 first gear 13 meshes with the internal teeth 17 of the second gear 18. As a result of a different number of teeth, z. B. 60 to 66, the first gear 13 receives a larger rotational speed n 1 with respect to a rotational speed n 2 of the roll shell 02 with the second gear 18th

Über die Kupplung 26 wird das den Innenring 34 tragende, schräg stehende Antriebsteil 33 gedreht. Die Hubfrequenz entspricht der Differenzgeschwindigkeit, die von beiden Zahnrädern 13; 18 erzeugt wird.About the coupling 26, the inner ring 34 supporting, inclined drive member 33 is rotated. The stroke frequency corresponds to the differential speed of the two gears 13; 18 is generated.

Infolge der radialen Verstellbarkeit der Kugelpfanne des Gelenkes 44 auf dem Außenring 38 kann die Hublänge h des Walzenmantels 02 verändert, z. B. verkürzt werden.Due to the radial adjustability of the ball socket of the joint 44 on the outer ring 38, the stroke length h of the roll shell 02 can be changed, for. B. be shortened.

Die Kupplung 26 hat eine ausgleichende Wirkung zwischen den exzentrisch gelagerten Stehbolzen 20 bis 23, die jeweils mit ihrem Umfang an der Innenwand der Bohrungen 27 bis 30 abrollen. Die Bohrungen 27 bis 30 sind zentrisch zur Rotationsachse 12 angeordnet.The coupling 26 has a balancing effect between the eccentrically mounted stud bolts 20 to 23, each roll with its circumference on the inner wall of the bores 27 to 30. The bores 27 to 30 are arranged centrically to the axis of rotation 12.

Dazu ist in Fig: 3 jeweils eine erste Position der Stehbolzen 20 bis 23 und Bohrungen 27 bis 30 und eine gestrichelte zweite Position nach Drehung um 45° dargestellt. In der Schnittdarstellung nach Fig. 3 ist das Kugellager 32, die Hülse 48 sowie der Walzenmantel 02 nicht dargestellt.For this purpose, a first position of the stud bolts 20 to 23 and bores 27 to 30 and a dashed second position after rotation by 45 ° are shown in FIG. In the Sectional view of FIG. 3, the ball bearing 32, the sleeve 48 and the roll shell 02 is not shown.

Nach einer Ausführungsvariante der Erfindung ist vorgesehen, daß das Getriebe 09 zum Erzeugen einer von der Drehzahl n2 des Walzenmantels 02 abweichenden Drehzahl n1 sowie die Mittel 36; 39; 02 zum Erzeugen des axialen Hubes h als kompakter axialer Einschub in den Walzenmantel 02 ausbildbar ist. Dazu ist am Inneren 16 des Walzenmantels 02 noch eine verdrehfeste Hülse 48 vorgesehen. Weiterhin ist es alternativ auch möglich, den Innenring 34 des Lagers 36 mit dem Inneren 16 des Walzenmantels 02 gelenkig zu verbinden. Der Außenring 38 ist dann bezüglich der axialen Richtung A der Reibwalze 01 gesehen ortsfest angeordnet.According to one embodiment of the invention, it is provided that the gear 09 for generating a deviating from the rotational speed n 2 of the roll shell 02 speed n 1 and the means 36; 39; 02 for generating the axial stroke h as a compact axial slot in the roll shell 02 can be formed. For this purpose, a non-rotatable sleeve 48 is still provided on the interior 16 of the roll shell 02. Furthermore, it is alternatively also possible to connect the inner ring 34 of the bearing 36 with the interior 16 of the roll shell 02 in an articulated manner. The outer ring 38 is then arranged stationary with respect to the axial direction A of the friction roller 01 seen.

Nach einer anderen Ausführungsvariante können die Stehbolzen 20 bis 23 der Kupplung aus einem elastischen Material sein. Zumindest jedoch weisen die Stehbolzen 20 bis 23 eine elastische Umhüllung auf, ohne ihren Durchmesser d zu verändern.According to another embodiment, the studs 20 to 23 of the coupling may be made of an elastic material. However, at least the stud bolts 20 to 23 have an elastic covering without changing their diameter d.

Es ist natürlich auch möglich, die mit den Stehbolzen 20 bis 23 in Eingriff stehenden Bohrungen 27 bis 30 innen mit elastischen Material auszukleiden. Dabei bleibt der Durchmesser D der Bohrungen 27 bis 30 erhalten.Of course, it is also possible to line the standing with the stud bolts 20 to 23 in holes 27 to 30 with elastic material. In this case, the diameter D of the holes 27 to 30 is maintained.
