Abstract

The bearing has a socket for fixing the axis in the machine frame and this socket (1) is set in a bore (5) of the frame and has a longitudinal slit so that when the draw roller axis is clamped the socket is spread out and locks free of play in the wall. The socket can have one full length slit or two opposite slit tongues running in the longitudinal direction.The socket can have a radial locking screw. ADVANTAGE - The bearing can be made cost-effectively without flanges.

Description

Die Erfindung betrifft ein Lager für Leitwalzen für Bahnen, beispielsweise in Rollenrotationsdruckmaschinen.The invention relates to a bearing for guide rollers for webs, for example in web-fed rotary printing machines.

An Rollenrotationsdruckmaschinen kommen Leitwalzen zur Anwendung, bei denen der Walzenmantel drehbar auf einer feststehenden Achse gelagert ist. Die Achse wird beiderseits mittels auf ihr schiebbarer Büchsen im Maschinengestell gelagert. Hierzu ist in jede Maschinenseitenwand an der Innenseite in eine Bohrung ein Bolzen mit Kopf eingesteckt, dessen Kopfdurchmesser gleich dem Durchmesser der Walzenachse ist. Die Büchsen werden beim Einbau der Leitwalze auf den Bolzenkopf geschoben und halten diese. Die Büchsen tragen einen Flansch, mit dem sie zur Lagesicherung an der Maschinenseitenwand angeschraubt werden. Weiterhin ist am Büchsenmantel eine radial gerichtete Klemmschraube zur spielfreien Fixierung des Walzenzapfens vorgesehen.Guide rollers are used on web-fed rotary printing machines, where the roller shell rotates on a fixed axis is stored. The axis is on both sides by means of it sliding bushes stored in the machine frame. This is in each machine side wall in a hole on the inside Bolt inserted with head, the head diameter of which is the same The diameter of the roller axis is. The rifles are installed the guide roller pushed onto the bolt head and hold it. The Bushings have a flange with which they can be used to secure the position screwed onto the machine side wall. Furthermore is on Bushing a radially directed clamping screw for play-free fixation of the roll neck provided.

Diese Lagerung ist infolge mehrerer material- und fertigungsaufwendiger Einzelteile kostspielig. Weiterhin bedingt die Flanschbefestigung der Büchse einen erhöhten Platzbedarf.This storage is due to several material and production-intensive individual parts costly. Still conditional the flange mounting of the sleeve requires more space.

Der Erfindung liegt die Aufgabe zugrunde, ein Lager für Leitwalzen für Bahnen mit einer Achse, auf der drehbar der Walzenmantel und schieb- und radial klemmbar eine Büchse zur Befestigung der Achse im Maschinengestell angeordnet ist, zu schaffen, das aus wenigen einfach gestalteten Einzelteilen besteht. Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Büchse in einer Wandbohrung aufgenommen wird und eine Längsschlitzung aufweist. Dank der Schlitzung wird bei der Klemmung der Zugwalzenachse gleichzeitig die Büchse gespreizt und spielfrei in der Wand arretiert. Dadurch erübrigen sich weitere Einzelteile, und das einzige Fertigungsteil des Lagers ist flanschlos und gestattet dessen kostengünstige Herstellung.The invention has for its object a bearing for Guide rollers for webs with an axis on which the Roll sleeve and sliding and radially clampable a sleeve Fastening the axis in the machine frame is arranged too create that from a few simply designed individual parts consists. The object is achieved in that the Bushing is received in a wall hole and a Has longitudinal slit. Thanks to the slit, the Clamping the pull roller axis simultaneously spread the bushing and locked in the wall without play. This eliminates the need for more Individual parts, and the only manufacturing part of the warehouse is flangeless and allows its cost-effective production.

Die Büchse wird vorteilhaft in der Wandbohrung geklemmt, wenn erfindungsgemäß die Büchse einen durchgehenden Längsschlitz oder zwei einander gegenüberliegende, in Längsrichtung verlaufende Einschlitzungen aufweist.The sleeve is advantageously clamped in the wall hole, if According to the invention, the bush has a continuous longitudinal slot or two opposite one another, running in the longitudinal direction Has slits.

Die Erfindung soll nachfolgend an einem Ausführungsbeispiel näher erläutert werden. In den zugehörigen Zeichnungen zeigtThe invention will be described in more detail below using an exemplary embodiment are explained. In the accompanying drawings

Fig. 1 ein Lager in der Seitenansicht, Fig. 1 a bearing in a side view;

Fig. 2 die Ansicht Z nach Fig. 1. Fig. 2 is the view Z of FIG. 1.

Das in Fig. 1 dargestellte Lager nimmt in einer Büchse 1 die Achse 2 der Leitwalze 3 auf, deren Mantel 4 auf der Achse 2 gelagert ist. Die Büchse 1 steckt in einer Bohrung 5 der Seitenwand 6 des Maschinengestells. Die Büchse 1 trägt zwei einander gegenüberliegende Einschlitzungen 7; 8 (Fig. 2). Um 90 Grad zu letzterem versetzt ist am nicht von der Bohrung 5 aufgenommenen Buchsenmantel eine radial gerichtete Klemmschraube 9 angeordnet. Ein gleichartiges Lager ist, nicht dargestellt, am anderen Ende der Achse 2 angeordnet.The bearing shown in Fig. 1 receives in a sleeve 1, the axis 2 of the guide roller 3 , the jacket 4 is mounted on the axis 2 . The sleeve 1 is in a bore 5 of the side wall 6 of the machine frame. The sleeve 1 has two mutually opposite slots 7; 8 ( Fig. 2). At 90 degrees to the latter, a radially directed clamping screw 9 is arranged on the socket casing not received in the bore 5 . A similar bearing, not shown, is arranged at the other end of the axis 2 .

Zum Einsetzen der Leitwalze 3 ins Maschinengestell wird diese zunächst bei vollständig auf die Achse 2 geschobener Büchse 1 in die Einbauposition gebracht. Anschließend wird die Büchse 1, die vorteilhaft abgesetzt ist, bis auf Anschlag in die Bohrung 5 geschoben, wodurch die Leitwalze 3 lagefixiert wird. Nachfolgend wird die Klemmschraube 9 angezogen und dabei die Achse 2 in der Büchse 1 und letztere in der Seitenwand 6 arretiert.To insert the guide roller 3 into the machine frame, this is first brought into the installation position with the bush 1 completely pushed onto the axis 2 . Then the bushing 1 , which is advantageously offset, is pushed into the bore 5 as far as it will go, as a result of which the guide roller 3 is fixed in position. Subsequently, the clamping screw 9 is tightened and the axis 2 is locked in the sleeve 1 and the latter in the side wall 6 .

Im Ausführungsbeispiel weist die Büchse zwei Einschlitzungen auf. Die Längsschlitzung kann ebenso zum Gegenstand der Erfindung gehörig in Form eines durchgehenden Längsschlitzes ausgeführt sein.In the exemplary embodiment, the sleeve has two slots. The longitudinal slit can also be the subject of the invention properly executed in the form of a continuous longitudinal slot be.
