Description

Die Erfindung bezieht sich auf ein Walzenlager für Walzen in Druckwerken einer Druckmaschine, insbesondere zur Lagerung von Farbwalzen, Feuchtwalzen oder dergleichen in einer Offset-Rotationsdruckmaschine nach dem Oberbegriff des Patentanspruches 1.The invention relates to a roller bearing for rollers in printing units of a printing press, in particular for storing inking rollers, dampening rollers or the like in an offset rotary printing press according to the preamble of claim 1.

Dieser Stand der Technik ergibt sich aus der DE 36 17 594 A1. Es wird hierin ein Walzenlager beschrieben, welches aus einer im vertikalen Schnitt in einer Ebene der Walzenachse winkelförmigen, oben offenen Aufnahme, die mit dem Gestell der Maschine verbindbar ist, und einem um die Walzenachse drehbaren Niederhalter besteht, so daß das Walzenlager durch Verdrehung des ringförmig ausgebildeten Niederhalters geöffnet werden kann, um den Walzenzapfen in die dann oben offene Aufnahme einlegen und das Walzenlager durch Rückdrehung des Niederhalters schließen zu können. Bei der bekannten Anordnung ist auf dem Zapfen am Walzenende ein Kugellager aufgesetzt, welches in die offene Aufnahme eingelegt und durch Verdrehung des Niederhalters festgehalten wird. Ein solches Walzenlager ist zwar relativ schnell verschließbar und leicht zu öffnen, aber aufgrund des erforderlichen Lagerspiels für schnellaufende Maschinen ungeeignet und stark verschmutzungsgefährdet, wodurch die Funktion beeinträchtigt wird. Der drehbare Niederhalter hat aufgrund von Fertigungstoleranzen Spiel, so daß auch das Lager der Walze mit einem Spiel in der Aufnahme liegt, welches aber zu vermeiden ist, weil es die Farbübertragung beeinträchtigt. Eine Sicherung gegen das öffnen in Drehrichtung wird in der Druckschrift zwar erläutert, aber das unerlaubte Verdrehen in Gegenrichtung ist nicht gesichert, so daß eine öffnung durch einfache Vibrationen möglich ist oder bei einem Rückwärtslauf der Maschine, wie es im Schleichgang üblich ist. Wegen der Enge des zur Verfügung stehenden Bauraumes bringt ein Niederhalterring Probleme mit sich.This prior art results from DE 36 17 594 A1. A roller bearing is described herein, which consists of a vertical opening in a plane of the roller axis, an open top receptacle that can be connected to the frame of the machine, and a hold-down device that can be rotated about the roller axis, so that the roller bearing is rotated by rotating the ring trained hold-down device can be opened in order to insert the roll neck into the receptacle which is then open at the top and to be able to close the roll bearing by turning the hold-down device back. In the known arrangement, a ball bearing is placed on the pin at the roller end, which is inserted into the open receptacle and held in place by turning the hold-down device. Such a roller bearing can be closed relatively quickly and is easy to open, but is unsuitable for high-speed machines due to the required bearing play and is at high risk of contamination, which impairs the function. The rotatable hold-down device has play due to manufacturing tolerances, so that the roller bearing also has play in the receptacle, but this should be avoided because it impairs the ink transfer. A safeguard against opening in the direction of rotation is explained in the document, but the unauthorized twisting in the opposite direction is not secured, so that an opening by simple vibrations is possible or when the machine runs backwards, as is customary in creep speed. A hold-down ring causes problems because of the limited space available.

Aus der EP 0 328 879 B1 ist ein Walzenlager mit einem Walzenschloß bekannt, bei dem auf den am Ende der Walze angeordneten Zapfen ein Lagerring aufgesteckt wird, der einen an zwei Seiten abgeflachten Führungszapfen aufweist und mit diesem Führungszapfen durch einen Schlitz von oben in eine runde Aufnahme eingelegt und darin nach Verdrehung durch einen Federstift gesichert wird. Ein solches Walzenlager ist bei hohen Anforderungen an die Druckqualität ebenfalls mit einer exzentrisch wirksamen Nachstelleinrichtung auszurüsten, um das für den Ausbau und Wiedereinbau notwendige Spiel zur Bewegung der Lagerteile relativ zueinander auszugleichen.From EP 0 328 879 B1 a roller bearing with a roller lock is known, in which a bearing ring is fitted onto the pin arranged at the end of the roller, which has a guide pin flattened on two sides and with this guide pin through a slot from above into a round one Inserted and secured in place after rotation by a spring pin. Such a roller bearing is also to be equipped with an eccentrically effective adjusting device in the case of high demands on the print quality, in order to compensate for the play necessary for the removal and reinstallation for moving the bearing parts relative to one another.

Der Erfindung liegt die Aufgabe zugrunde, ein aus möglichst wenig Einzelteilen aufgebautes, einfaches Walzenlager zu schaffen, welches auf engstem Raum eine sichere, spielfreie Walzenlagerung auch bei hohen Drehzahlen ergibt und den schnellen Ausbau und fehlerfreien Wiedereinbau von Walzen in Druckwerken von Druckmaschinen ermöglicht.The invention has for its object to provide a simple roller bearing constructed from as few individual parts as possible, which results in a safe, play-free roller bearing in a confined space even at high speeds and enables the rapid removal and error-free reinstallation of rollers in printing units of printing presses.

Die Erfindung löst diese Aufgabe durch ein Walzenlager mit Ausbildungsmerkmalen nach dem Patentanspruch 1.The invention solves this problem by a roller bearing with training features according to claim 1.

Die einfachen Bauteile reduzieren die Herstellungskosten eines solchen Walzenlagers. Durch die Verspannung des Niederhalters mit der Aufnahme durch einen federbelasteten Bolzen wird ein radiales Spiel ausgeschaltet und sind die radial auf das Walzenlager einwirkenden Kräfte kontrollierbar. Bevorzugt sollen Tellerfedern verwendet werden, weil dadurch große Federkräfte auf engstem Raum unterzubringen sind. Für das öffnen des Walzenlagers und auch für das Schließen des Walzenlagers kann ein Werkzeug benutzt werden, welches stirnseitig am Bolzenkopf angesetzt wird. Ein Lager mit den Erfindungsmerkmalen ist weitestgehend verschmutzungsfrei und sowohl für feste Zapfen am Walzenende als auch für auf das Zapfenende aufgesetzte Wälzlager anwendbar. Am Walzenzapfen sind keine Veränderungen vorzunehmen. Es sind auch keine Adapterstücke erforderlich. Ein Walzenschloß mit den neuen Ausbildungsmerkmalen ist universell verwendbar.The simple components reduce the manufacturing costs of such a roller bearing. By clamping the hold-down with the holder by means of a spring-loaded bolt, radial play is eliminated and the forces acting radially on the roller bearing can be controlled. Disc springs should preferably be used because this means that large spring forces can be accommodated in the smallest of spaces. A tool can be used to open the roller bearing and also to close the roller bearing which is attached to the face of the bolt head. A bearing with the features of the invention is largely contamination-free and can be used both for fixed pins on the roller end and for roller bearings placed on the pin end. No changes need to be made to the roll neck. No adapter pieces are required. A roller lock with the new training features can be used universally.

Die Unteransprüche 2 bis 7 enthalten weitere Merkmale zur vorteilhaften Gestaltung des Erfindungsgedankens.The sub-claims 2 to 7 contain further features for the advantageous design of the inventive concept.

Das Walzenlager gemaß dem Ausführungsbeispiel besteht aus einer gegebenenfalls fest mit einer einstellbaren Schwinge 1 oder auch unmittelbar mit dem Gestell der Maschine verbindbaren Aufnahme 2, dem Niederhalter 3 und den beide miteinander verbindenden Bolzen 4.The roller bearing according to the exemplary embodiment consists of a receptacle 2, which can optionally be fixedly connected to an adjustable rocker 1 or also directly to the frame of the machine, the hold-down device 3 and the bolts 4 connecting the two.

In dem Beispiel der Figuren 2 bis 4 ist die Aufnahme 2 an der der Walze zugewendeten Stirnfläche eines Lagerkörpers 5 ausgebildet, der seinerseits mit dem Gestell 1 verbindbar ist. Die Aufnahme 2 weist im unteren Bereich eine nach oben offene Stützfläche 6 für den am Ende der Walze ausgebildeten Zapfen 7 oder für ein auf diesen Zapfen aufgestecktes Lager 8 auf. Die Stützfläche 6 erstreckt sich über einen vorgegebenen Winkelbereich. Ihr diametral etwa gegenüberliegend ist der Niederhalter 3 angeordnet, welcher an seiner Unterseite ebenfalls eine kreisrunde Stützfläche 9 aufweist, die von oben entweder gegen den Zapfen 7 oder gegen ein auf diesen Zapfen aufgestecktes Lager 8 liegt. Niederhalter und Aufnahme umschließen somit den Zapfen bzw. das Lager über einen gewissen Umfangsbereich, der eine sichere Halterung gewährleistet und sind durch eine Feder radial gegeneinander verspannt. Der Niederhalter 3 und die Aufnahme 2 sind durch den in einer radial zur Walzenachse verlaufenden Bohrung des Lagerkörpers 5 angeordneten Bolzen 4 miteinander verbunden und durch auf den Bolzen 4 aufgesteckte Tellerfedern 10 gegeneinander verspannt. Die Spannkräfte lassen sich durch Verschrauben der Mutter 11 auf den Bolzen 4 einstellen. In dem gewählten Ausführungsbeispiel sind der Niederhalter 3 und der Bolzen 4 durch eine Schraube 12 oder andere Mittel drehfest miteinander verbunden. Zum Öffnen und Schließen des Walzenlagers wird stirnseitig mit dem Kopf 13 des Bolzens 4 ein Werkzeug verbunden, welches beispielsweise in einen Innensechskant 14 des Bolzenkopfes 13 einsteckbar ist. Auf diese Weise ist der Niederhalter 3 um 90x verschwenkbar, so daß er zur Seite weisend das Lager 8 bzw. d en Zapfen 7 freigibt, um diesen aus der Aufnahme 2 herauszuheben. In dem geschlossenen Walzenlager ist der Zapfen 7 bzw. ein Lager 8 auf dem Zapfen 7 durch die Rundung des Niederhalters und der Aufnahme formschlüssig gesichert. Zum öffnen muß der Niederhalter um das Maß der Rundung seiner Stützfläche 9 in axialer Richtung des Bolzens 4 angehoben werden. Entsprechend ist beim Schließen des Lagers eine axiale Bewegung des Bolzens 4 erforderlich. Um die Federkräfte aus der Tellerfeder 10 bei geschlossenem Lager wirksam werden zu lassen, ist zwischen der Unterseite des Niederhalters 3 und der benachbarten Oberfläche des Lagerkörpers 5 ein Spalt vorgesehen, so daß sich der Niederhalter und der Lagerkörper bei geschlossenem Lager an dieser Fläche nicht berühren.In the example of FIGS. 2 to 4, the receptacle 2 is formed on the end face of a bearing body 5 which faces the roller and which in turn can be connected to the frame 1. The receptacle 2 has in the lower region an upwardly open support surface 6 for the pin 7 formed at the end of the roller or for a bearing 8 plugged onto this pin. The support surface 6 extends over a predetermined angular range. The hold-down device 3 is arranged diametrically opposite one another, which also has a circular support surface 9 on its underside, which lies from above either against the pin 7 or against a bearing 8 fitted onto this pin. The hold-down device and the receptacle thus enclose the pin or the bearing over a certain circumferential area, which ensures secure mounting, and are radially braced against one another by a spring. The hold-down device 3 and the receptacle 2 are connected to one another by the bolts 4 arranged in a bore of the bearing body 5 that runs radially to the roller axis and are braced against one another by plate springs 10 attached to the bolts 4. The clamping forces can be adjusted by screwing the nut 11 onto the bolt 4. In the selected embodiment, the hold-down device 3 and the bolt 4 are connected to one another in a rotationally fixed manner by a screw 12 or other means. To open and close the roller bearing, a tool is connected at the end to the head 13 of the bolt 4, which tool can be inserted, for example, into a hexagon socket 14 of the bolt head 13. In this way, the hold-down device 3 can be pivoted 90 times, so that it releases the bearing 8 or the pin 7 to the side in order to lift it out of the receptacle 2. In the closed roller bearing, the pin 7 or a bearing 8 on the pin 7 is positively secured by the rounding of the hold-down device and the receptacle. To open the hold-down device must be raised by the amount of curvature of its support surface 9 in the axial direction of the bolt 4. Accordingly, an axial movement of the Bolt 4 required. In order to allow the spring forces from the plate spring 10 to take effect when the bearing is closed, a gap is provided between the underside of the hold-down device 3 and the adjacent surface of the bearing body 5, so that the hold-down device and the bearing body do not touch on this surface when the bearing is closed.

Ein Walzenlager in der beschriebenen Ausbildung ermöglicht eine einfache, schnelle und sichere Bedienung durch 90x-Schwenkung des Niederhalters und formschlüssige Sicherung des Walzenzapfens bei geschlossenem Walzenlager. Die radial im Walzenlager wirksamen Federkräfte sind kontrollierbar. Eine Fehlbedienung durch zu festes Einspannen und eventuell plastische Verformung der Teile des Walzenlagers sind somit ausgeschlossen. Das Walzenlager mit den Erfindungsmerkmalen erfordert keine Anpassung des Walzenzapfens bzw. eines auf diesen Walzenzapfen aufgesteckten Lagers, so daß sowohl feste Walzenzapfen als auch drehende Walzenzapfen durch das Walzenlager eingespannt werden können. Es gibt nicht nur eine definierte Lage des Niederhaltrs bei geöffnetem Lager, sondern vor allem auch ein eindeutiges Einrasten des Niederhalters bei geschlossenem Lager. Von besonderem Vorteil ist schließlich, daß Achsenwinkelfehler durch die federnde Einspannung ausgeglichen werden.A roller bearing in the design described enables simple, quick and safe operation by 90x swiveling of the hold-down device and positive locking of the roller journal when the roller bearing is closed. The spring forces acting radially in the roller bearing are controllable. Incorrect operation due to too tight clamping and possibly plastic deformation of the parts of the roller bearing are therefore excluded. The roller bearing with the features of the invention does not require any adaptation of the roller pin or of a bearing fitted onto this roller pin, so that both fixed roller pins and rotating roller pins can be clamped by the roller bearing. There is not only a defined position of the hold-down when the bearing is open, but above all there is a clear engagement of the hold-down when the bearing is closed. Finally, it is particularly advantageous that axis angle errors are compensated for by the resilient clamping.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, den Formschluß nicht durch die beschriebene Rundung im Niederhalter 3 über dem Lager 8 bzw. dem Wellenzapfen 7, auf den das Lager 8 aufgesteckt ist, auszuführen, sondern durch eine entsprechende Gestaltung zwischen dem Niederhalter 3 und dem Lagerkörper 5 mit der Aufnahme.In a further embodiment of the invention, it is provided that the positive connection is not carried out by the rounding described in the hold-down device 3 above the bearing 8 or the shaft journal 7, on which the bearing 8 is attached, but by a corresponding design between the hold-down device 3 and the bearing body 5 with the recording.
