[Aufgabe der Erfindung]OBJECT OF THE INVENTION

Der Erfindung liegt die Aufgabe zu Grunde, ein Schmiersystem der eingangs genannten Art zu schaffen, dass die genannten Nachteile vermeidet, das insbesondere eine gleichmäßigere Schmierung der Steuereinheit eines rotationssymmetrischen Bauteiles gestattet und das eine Reibungs- und Verschleißreduzierung an den Elementen der Steuereinheit erlaubt.The object of the invention is a lubrication system of the type mentioned at the outset to create that Avoids disadvantages, in particular a more uniform Lubrication of the control unit of a rotationally symmetrical Component allowed and that a reduction in friction and wear allowed on the elements of the control unit.

Erfindungsgemäß wird die Aufgabe durch die Ausbildungsmerkmale des Hauptanspruches gelöst. Weiterbildungen ergeben sich aus den Unteransprüchen.According to the invention, the task is based on the training features of the main claim solved. Further training results from the subclaims.

Ein erster Vorteil des erfindungsgemäßen Schmiersystems ist darin begründet, dass dieses kontinuierlich auf die Steuerelemente aufweisende Steuereinheit eines rotationssymmetrischen Bauteils einwirkt. Bei diesem Permanent-Schmiersystem ist ein manuelles Abschmieren der Steuereinheit, bevorzugt nach Schmierplan, hinfällig und ein mögliches subjektives Fehlverhalten ist damit ausgeschlossen.A first advantage of the lubrication system according to the invention is reasoned that this is continuously on the controls having control unit of a rotationally symmetrical Component acts. With this permanent lubrication system manual lubrication of the control unit is preferred according to lubrication plan, lapsed and a possible subjective Misconduct is therefore excluded.

Von Vorteil ist weiterhin, dass bevorzugt ein einheitliches Schmiermittel für alle zu schmierenden Steuerelemente, vorzugsweise gleichzeitig für die mit Umlaufschmierung versehenen Lagerungen, des rotationssymmetrischen Bauteiles einsetzbar ist.Another advantage is that preferably a uniform Lubricant for all control elements to be lubricated, preferably at the same time for those with circulating lubrication Bearings, the rotationally symmetrical component can be used is.

Vorteilhaft ist ebenso, dass die Steuerelemente der Steuereinheit eine vollständige Kapselung aufweisen. Damit ist neben der Schmiermittelversorgung eine Lärmreduzierung und ein Schutz vor Verschmutzungen erzielbar. Weiterhin ist mit diesem kontinuierlich wirksamen Schmiersystem eine Kühlung und ein Korrisionsschutz an den Elementen der Steuereinheit erzielbar, was insgesamt zur Reibungs- und Verschleißreduzierung beträgt.It is also advantageous that the control elements of the control unit have a complete encapsulation. So that is in addition to the lubricant supply, noise reduction and protection against contamination can be achieved. Furthermore, with cooling this continuously effective lubrication system and a protection against corrosion on the elements of the control unit achievable, what overall to reduce friction and wear is.

Als weitere Vorteile sind noch zu nennen, dass eine Erhöhung der Zuverlässigkeit der Steuereinheit bevorzugt durch eine kontinuierliche Schmierung dieser Kammer realisierbar ist. Ein Einsatz von verschiedensten Überwachungseinrichtungen ist überflüssig und die Wartungskosten der Schmierstellen, insbesondere gegenüber der manuellen Schmierung sind reduzierbar. Letztlich ist es vorteilhaft, das die Unfallsicherheit im Maschinenbetrieb erhöht wird und ein möglicher Kontakt des Bedruckstoffes mit Schmiermittel ausgeschlossen ist.Other benefits include an increase the reliability of the control unit preferably by continuous lubrication of this chamber is feasible. A variety of monitoring devices is used superfluous and the maintenance costs of the lubrication points, in particular compared to manual lubrication can be reduced. Ultimately, it is advantageous that the accident safety in the Machine operation is increased and a possible contact of the Substrate with lubricant is excluded.

Für den Bogentransport in Förderrichtung sind zwischen den Druckwerken wieder Bogenführungszylinder als doppelt große Transferzylinder angeordnet, wobei auch eine doppelt große Wendetrommel als Bogenführungszylinder, zum Beispiel nach dem Prinzip der Hinterkantenwendung als Eintrommelwendung, einsetzbar ist.
Ein derartig als Bogenführungszylinder ausgebildetes rotationssymmetrisches Bauteil 2 ist wiederum in je einem Lager 12 in einem Seitengestell 1 rotierbar aufgenommen. Mit Bezug auf einen einfach großen Platten-Platten-/Gummituchzylinder ist das rotationssymmetrische Bauteil 2 doppelt groß ausgebildet, das heißt am Umfang sind zwei diametral (um 180° versetzt) angeordnete Bogenhaltesysteme 6, 7 angeordnet.The invention will be further described on the basis of the rotationally symmetrical component 2, which is preferably arranged as a sheet guiding cylinder in a printing press.
