Abstract

To provide a snug-fitting bearing for journalling the spindle end of a printing press cylinder, a flanged bearing sleeve is disposed in a bore in the press frame and an anti-friction plastic material which compensates for the bearing play is injected into an external annular groove in the bearing sleeve of considerably less width than the depth of the bore in the press frame. Preferably, the bore is pretreated with a volatile release agent and the plastic material cures in situ to become a narrow bearing ring in the groove. The bearing sleeve may have eccentric annular shoulders on either side of the groove and a thin annular metal bushing may be interposed between the cylinder spindle and the interior of the sleeve bearing.

Description

Die Erfindung betrifft ein Lager für Zylinder von Druckmaschinen gemäß dem Oberbegriff von Anspruch 1.The invention relates to a bearing for cylinders of printing machines according to the preamble of claim 1.

Ein derartiges Lager ist aus der US-A-4 252 059 bzw. dem DE-GM 7 825 594 bekannt. Gerade letzteres Lager gewährleistet dabei eine absolut spielfreie Lagerung der Zylinderlaufbuchse im Gestell. Diese ist zur Druckan- bzw. Druckabschaltung des Zylinders auch nach Wärmedehnungen bei in etwa gleichbleibendem Drehmoment zu verschwenken. Das Kunststoffmaterial des Lagerrings ergibt ferner eine stoßdämpfende Wirkung und der Stick-Slip-Effekt wird vermieden. Auch wird die Reibung für das Verschwenken der Zylinderlaufbuchse herabgesetzt und es ergibt sich aufgrund von Selbstschmierung eine gewisse Wartungsfreiheit.Such a bearing is known from US-A-4 252 059 and DE-GM 7 825 594. The latter bearing in particular ensures that the cylinder liner is mounted absolutely free of play in the frame. To turn the pressure on or off the cylinder, this should also be pivoted after thermal expansion while the torque remains approximately the same. The plastic material of the bearing ring also has a shock-absorbing effect and the stick-slip effect is avoided. The friction for pivoting the cylinder liner is also reduced and there is a certain freedom from maintenance due to self-lubrication.

Von Nachteil ist bei einer derartigen Lageranordnung jedoch, daß eine spielfreie Paarung zwischen den Bohrungen im Gestell und dem Flanschlager (Zylinderlaufbuchse) in aufwendiger Weise meßtechnisch ausgesucht werden muß. Der Lagerring muß mit hoher Präzission im vorbestimmten Dickenmaß gefertigt sein, was bei Kunststoff sehr schwierig ist. Von entscheidendem Nachteil ist jedoch, daß wegen der schlechten Wärmeleitfähigkeit eines vollflächigen Lagerrings aus Kunststoff die Gefahr besteht, daß die Wärmeleitfähigkeit im gesamten Lagerbereich verschlechtert wird. Dieser Nachteil tritt allgemein auch bei den in der Praxis bekannten kunststoffbeschichteten Rundführungen auf, in die ein Gleitbelag z.B. aus aushärtbaren Kunstharzen über die gesamte Gleitfläche einer Gleitpaarung, in der Regel auf das kürzere Führungsteil, eingepreßt oder auf andere Weise aufgetragen wird.The disadvantage of such a bearing arrangement, however, is that a play-free pairing between the bores in the frame and the flange bearing (cylinder liner) must be selected in a complex measuring technique. The bearing ring must be made with high precision in the predetermined thickness, which is very difficult with plastic. A crucial disadvantage, however, is that because of the poor thermal conductivity of a full-surface bearing ring made of plastic, there is a risk that the thermal conductivity will be impaired in the entire bearing area. This disadvantage generally also occurs with the plastic-coated circular guides known in practice, into which a sliding coating e.g. made of curable synthetic resins is pressed over the entire sliding surface of a sliding pair, usually onto the shorter guide part, or applied in some other way.

Aus der DE-B-1 116 481 ist es bekannt, eine Anordnung zur Verbindung von zwei mit Präzissionspassung ineinandergesteckten Bauteilen, die aus Werkstoffen mit verschiedenen Wärmeausdehnungskoeffizienten bestehen, eine ringförmige Zwischenlage aus einem Werkstoff einzulegen, die einen höheren Wärmeausdehnungskoeffizienten und einen kleineren Elastizitätsmodul als die Werkstoffe der zu verbindenden Bauteile aufweist. Als Werkstoff für diese Zwischenlage kann unter anderem auch Kunststoff verwendet werden. Diese vorbekannte Verbindung hat jedoch die Aufgabe, einen gegenseitigen Ausgleich der durch Temperaturänderungen hervorgerufenen ungleichmäßigen Dehnungen der beiden ineinandergesteckten Bauteile zu bewirken, damit eine ursprüngliche Passung erhalten bleibt.From DE-B-1 116 481 it is known to insert an annular intermediate layer made of a material which is a higher one, for connecting two components which are fitted into one another with a precision fit and which consist of materials with different coefficients of thermal expansion Has thermal expansion coefficient and a smaller modulus of elasticity than the materials of the components to be connected. Plastic can also be used as the material for this intermediate layer. However, this previously known connection has the task of compensating each other for the uneven expansions of the two nested components caused by temperature changes, so that an original fit is retained.

Aufgabe der vorliegenden Erfindung ist es somit, ein absolut passendes Lager gemäß dem Oberbegriff von Anspruch 1 derartig weiterzubilden, so daß bei vereinfachter Herstellung und erleichterter Montage auch die Wärmeleitfähigkeit im Lagerbereich erhalten bleibt.The object of the present invention is therefore to develop an absolutely suitable bearing according to the preamble of claim 1 in such a way that, with simplified manufacture and easier assembly, the thermal conductivity in the storage area is also retained.

Gelöst wird diese Aufgabe gemäß dem Kennzeichen des ersten Patentanspruches. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen in Verbindung mit der Beschreibung und der Zeichnung.This object is achieved according to the characterizing part of the first claim. Further developments of the invention result from the subclaims in connection with the description and the drawing.

Das erfindungsgemäße Lager weist viele Vorteile auf. Die Wärme kann vor und hinter dem Lagerring aus Kunststoff ungehindert abfließen. Bis zu einem Temperaturunterschied von 5° Celsius zwischen Lager und Gestell ist die Funktion der Druckabstellung noch völlig einwandfrei gegeben, d.h. es tritt keine Veränderung im Drehmoment auf. Die Wärmeausdehnung im Lager wirkt sich nicht auf die Zylinderlaufbuchse aus. Das Lager ist auch bei nicht Erreichen der Betriebstemperatur bereits ausreichend spielfrei. Ferner wirkt das Kunststoffmaterial des Lagerringes sehr stark schwingungsdämpfend und die bekannten Notlaufeigenschaften sind gegeben. Da die Ausdehnung des Materials des Lagerringes größer als bei einem metallischen Lagerwerkstoff, z.B. Guß ist, wird das Zylinderlager bei Betriebstemperatur leicht vorgespannt. Dieses Lager ist unempfindlich gegen Druckeinsatzstreifen. Nicht zuletzt ist die Herstellung und Montage erleichtert, so daß auch für den Service die kundenseitige Ausspritzmöglichkeit gegeben ist.The bearing according to the invention has many advantages. The heat can flow freely in front of and behind the plastic bearing ring. Up to a temperature difference of 5 ° Celsius between the bearing and the frame, the function of the print shutdown is still completely flawless, i.e. there is no change in torque. The thermal expansion in the bearing has no effect on the cylinder liner. The bearing is already sufficiently free of play even if the operating temperature is not reached. Furthermore, the plastic material of the bearing ring has a very strong vibration damping and the known emergency running properties are given. Since the expansion of the material of the bearing ring is greater than that of a metallic bearing material, e.g. Is cast, the cylinder bearing is slightly preloaded at operating temperature. This bearing is insensitive to pressure strips. Last but not least, the manufacture and assembly is facilitated, so that the customer can also spray out the service.

An einem Ausführungsbeispiel soll anhand der Zeichnung nachfolgend die Erfindung näher erläutert werden.In one embodiment, the invention will be explained in more detail with reference to the drawing.

Es zeigt:

Fig. 1
ein Lager für Zylinder von Druckmaschinen im Gestell einer Druckmaschine, im Schnitt,
Fig. 2
eine Draufsicht auf das Flanschlager 3.
It shows:
Fig. 1
a bearing for cylinders of printing machines in the frame of a printing machine, in section,
Fig. 2
a plan view of the flange bearing 3.

Wie aus Fig. 1 zu ersehen ist, ist ein Flanschlager 3 in der Bohrung 7 des Gestells 5 bzw. innerhalb einer mit einer Bohrung 7 versehenen geschliffenen Stahlbüchse des Gestells 5 auf einer Zylinderlaufbuchse 2 angeordnet. In der Zylinderlaufbuchse 2 gleitet der Zylinderzapfen 1. Die Zylinderlaufbuchse 2 und/oder das Flanschlager 3 sind exzentrisch gebohrt.As can be seen from FIG. 1, a flange bearing 3 is arranged in the bore 7 of the frame 5 or within a ground steel bushing of the frame 5 provided with a bore 7 on a cylinder liner 2. The cylinder journal 1 slides in the cylinder liner 2. The cylinder liner 2 and / or the flange bearing 3 are drilled eccentrically.

Mittig in die Lagerfläche des Flanschlager 3 ist eine ca. 25 mm breite Ringnut 9 eingedreht, deren Breite somit erheblich geringer ist, als die Tiefe der Bohrung 7 im Gestell 5. In die Ringnut 9 wird im eingebauten Zustand ein pastös zu verarbeitender Kunststoff eingepreßt, der im Lager zu einem fertigen Lagerring 6 aushärtet, wobei die Bohrung 7 mit einem Trennmittel 10 vorbehandelt ist. Zum Einpressen des pastösen Kunststoffes sind Bohrungen 8 im Flanschlager 3 angeordnet. Geeignet ist als pastöser Kunststoff z.B. ein aushärtbares Kunstharz für Gleitführungen.An approximately 25 mm wide annular groove 9 is screwed into the center of the bearing surface of the flange bearing 3, the width of which is therefore considerably smaller than the depth of the bore 7 in the frame 5. When installed, a pasty plastic is pressed into the annular groove 9, which hardens to a finished bearing ring 6 in the bearing, the bore 7 being pretreated with a release agent 10. Bores 8 are arranged in the flange bearing 3 for pressing in the pasty plastic. Suitable as pasty plastic e.g. a hardenable synthetic resin for sliding guides.

Die Herstellung bzw. Funktionsweise lassen sich wie folgt kurz zusammenfassen:
Das Flanschlager 3, das vorzugsweise aus Grauguß besteht, wird mit einem Spiel von mindestens 0,01 mm zur Bohrung 7 im Gestell 5 ausgemessen und in das Gestell 5 hineingeschoben. Zuvor wird die Innenwand der Bohrung 7 im Gestell 5 bzw. in der Stahlbüchse des Gestells 5 mit einem Trennmittel 10 beaufschlagt. Mit Hilfe der Einspritzbohrungen 8 wird nun der pastöse Kunststoff eingespritzt. Nach ca. 8 Stunden Aushärtezeit kann das Flanschlager 3 gezogen werden. Eine zusätzliche Nacharbeit am Durchmesser ist nicht erforderlich.The production or mode of operation can be briefly summarized as follows:
The flange bearing 3, which preferably consists of gray cast iron, is measured with a play of at least 0.01 mm to the bore 7 in the frame 5 and pushed into the frame 5. A release agent 10 is applied to the inner wall of the bore 7 in the frame 5 or in the steel bushing of the frame 5 beforehand. With the help of the injection holes 8, the pasty plastic is now injected. After a curing time of approx. 8 hours, the flange bearing 3 can be pulled will. Additional reworking of the diameter is not necessary.

Auf diese Weise wird in einfacher Weise ein Zylinderlager erzeugt, daß abzüglich der Trennmittelstärke von 3 bis 4 µm ein absolut passendes Zylinderlager ist, wobei das Flanschlager 3 leichtgängig im Drehgelenk 4 verschwenkbar bleibt.In this way, a cylinder bearing is produced in a simple manner that minus the release agent thickness of 3 to 4 μm is an absolutely suitable cylinder bearing, the flange bearing 3 remaining easily pivotable in the swivel joint 4.
