Abstract

The drive cogwheel (2) is connected to the drive of the printer. The drive is transmitted from a drive gearing (5) on a shaft (3) carrying the drive cogwheel via one or more planetary wheels (12) movable on a circle round the shaft, to a driven element (7). The planetary wheels move between the drive gearing and an internally cogged hollow wheel (14) adjustably fixed in its rotary position by the adjustment.

Description

Die Verbesserung betrifft eine Vorrichtung zur Verstellung des Verreibungseinsatzes in Farbwerken von Druckmaschinen nach dem Oberbegriff des Patentanspruchs 1. Eine Vorrichtung dieser Art ist aus der DE 38 14 927 C1 bekannt.The improvement relates to a device for adjusting the use of friction in inking units of printing presses according to the preamble of claim 1. A device of this type is known from DE 38 14 927 C1.

In Farbwerken von Druckmaschinen sind Reibwalzen zur Verteilung von zu transportierender Druckfarbe eingesetzt, die eine axial hin- und hergehende Bewegung ausführen. Für spezielle Erfordernisse bei der Einstellung des Farbtransports ist es wünschenswert die Lage der hin- und hergehenden Bewegung in Bezug zur allgemeinen Rotationsbewegung der Druckmaschine zu verändern.In inking units of printing machines, friction rollers are used to distribute the printing ink to be transported, which perform an axially reciprocating movement. For special requirements when setting the ink transport, it is desirable to change the position of the reciprocating movement in relation to the general rotary movement of the printing press.

In der DE 38 14 927 C1 ist ein Zwischengetriebe in Druckmaschinen zum Verstellen der Phasenlage der axialen Verreibungsbewegung von Reibwalzen beschrieben. Es dient dazu die hin- und hergehende Bewegung der Reibwalzen in einem Farbwerk einer Druckmaschine in Bezug auf eine allgemeine Rotationsbewegung in einem Druckwerk einstellbar zu machen. Dazu ist zwischen den Antrieb von der Druckmaschine her und den kurbelförmigen Abtrieb zu den Reibwalzen hin das genannte Zwischengetriebe eingesetzt. Es weist an einer Antriebswelle einen exzentrisch angesetzten Kurbelzapfen auf, der ein Übertragungselement trägt. An dem Übertragungselement ist einerseits ein Zahnrad vorgesehen und andererseits eine Scheibe angebracht, die drei Kurvenrollen trägt. Die Kurvenrollen greifen in entsprechende Öffnungen einer Steuerscheibe ein, die auf der Antriebswelle gelagert ist. Die Öffnungen haben gegenüber dem Durchmesser der Kurvenrollen einen um das Maß der Exzentrizität des Kurbelzapfens vergrößerten Durchmesser. Das Zahnrad auf dem Übertragungselement greift in eine Innenverzahnung eines Abtriebselements ein, das im Gehäuse des Zwischengetriebes gelagert ist. An diesem Abtriebselement ist ein Antriebshebel für die hin- und hergehende Bewegung der Reibwalzen verschiebbar angekoppelt. Die Ankoppelung erfolgt auf bekannte Weise.DE 38 14 927 C1 describes an intermediate gear in printing machines for adjusting the phase position of the axial rubbing movement of friction rollers. It serves to make the reciprocating movement of the friction rollers in an inking unit of a printing press adjustable in relation to a general rotational movement in a printing unit. For this purpose, the intermediate gear mentioned is inserted between the drive from the printing press and the crank-shaped output toward the friction rollers. It has an eccentrically attached crank pin on a drive shaft, which carries a transmission element. On the one hand, a gearwheel is provided on the transmission element and, on the other hand, a disc is attached, which carries three cam rollers. The cam rollers engage in corresponding openings in a control disk which is mounted on the drive shaft. Compared to the diameter of the cam rollers, the openings have a diameter enlarged by the degree of the eccentricity of the crank pin. The gearwheel on the transmission element engages in an internal toothing of an output element which is mounted in the housing of the intermediate gear. A drive lever for the reciprocating movement of the friction rollers is slidably coupled to this output element. The coupling takes place in a known manner.

Die Steuerscheibe ist ihrerseits mit einer Außenverzahnung versehen, in die ein Stellzahnrad eingreift, das von einem Kettentrieb gehalten oder verstellt werden kann.
Die Antriebsbewegung erfolgt durch exzentrischen Umlauf des Übertragungselement. Dabei rollt das Zahnrad des Übertragungselements in der Innenverzahnung des Abtriebselements ab und treibt dieses mit der entsprechenden Untersetzung an. Dabei bleibt das Übertragungselement abgesehen von der exzentrischen Bewegung relativ zum Gehäuse in Ruhe, wobei die Kurvenrollen in den Öffnungen der Steuerscheibe umlaufen. Durch Versstellen der Steuerscheibe mit dem Stellzahnrad kann die Abtriebsbewegung relativ zum Antrieb verstellt werden.The control disk is in turn provided with an external toothing in which an adjusting gear engages, which can be held or adjusted by a chain drive.
The drive movement takes place through eccentric rotation of the transmission element. The gearwheel of the transmission element rolls in the internal toothing of the output element and drives it with the appropriate reduction. Apart from the eccentric movement relative to the housing, the transmission element remains at rest, the cam rollers rotating in the openings of the control disk. By moving the control disc with the adjusting gear, the output movement can be adjusted relative to the drive.

Das Zwischengetriebe ist zwar recht kompakt, dabei aber relativ kompliziert und teuer in der Herstellung.The intermediate gear is quite compact, but it is relatively complicated and expensive to manufacture.

Aufgabe der Verbesserung ist es daher, das Getriebe günstiger in der Herstellung und dabei noch kompakter zu gestalten.The task of the improvement is therefore to make the transmission cheaper to manufacture and yet more compact.

Die Lösung der Aufgabe ergibt sich aus dem Kennzeichen des Anspruchs 1. Hierbei können vorteilhafterweise Standardbauteile verwendet werden, die die Kosten der Herstellung senken. Außerdem ist das Getriebe nur noch im wesentlichen in zwei Ebenen angeordnet. Dies ist einmal die Ebene der Untersetzung und der Einstellung, in der das eigentliche Planetengetriebe liegt. In der anderen Ebene sind der Abtrieb mit Abtriebselement und Verreibungsantrieb angeordnet. Die gesamte Getriebeanordnung wird dadurch nochmals sehr viel kompakter gestaltet.The solution of the task results from the characterizing part of claim 1. Here, standard components can advantageously be used which reduce the costs of production. In addition, the transmission is only essentially arranged in two planes. This is the level of the reduction and the setting in which the actual planetary gear lies. The output with output element and friction drive are arranged in the other level. The entire gear arrangement is thereby made much more compact.

Eine beispielhafte Ausführung eines Getriebes nach der Erfindung ist im folgenden anhand von Zeichnungen dargestellt.An exemplary embodiment of a transmission according to the invention is shown below with reference to drawings.

einen Schnitt in Achsrichtung und
Figur 2

It shows
Figure 1
a section in the axial direction and
Figure 2
a section in the plane of the planet gears.

In Figur 1 ist ein Schnitt durch die Vorrichtung in einer Ebene durch eine Mittelachse dargestellt. Die Vorrichtung ist am Maschinengestell 1 einer Druckmaschine angebracht. Sie enthält zunächst ein Antriebszahnrad 2, das mit einem maschinensynchronen Teil des Antriebs der Druckmaschine verbunden ist. Das Antriebszahnrad 2 ist auf einer Welle 3 angebracht. Die Welle 3 ist auf ihrer einen Seite mittels eines Lagers 4 im Maschinengestell 1 gelagert. Auf der gegenüberliegenden Seite der Welle 3 ist sind in axialer Richtung nebeneinander eine Antriebsverzahnung 5 und eine Nadellagerung 6 vorgesehen. Die Keilverbindung 6 greift in ein Abtriebselement 7 ein. Das Abtriebselement 7 ist im Prinzip als hohlzylindrischer Körper aufgebaut, der an der Innenseite entsprechend der Nadellagerung 6 auf dem Ende der Welle 3 ausgebildet ist. An dem Abtriebselement 7 ist weiterhin eine Klemmvorrichtung 8 vorgesehen. An der Klemmvorrichtung 8 wird über eine Bundbüchse 10 ein Antriebshebel 9 schwenkbar z.B. über ein Wälzlager befestigt. Der Antriebshebel 9 führt zu Umlenkgetrieben für die Einleitung einer hin- und hergehenden Bewegung von Reibwalzen in einem Farbwerk der Druckmaschine.FIG. 1 shows a section through the device in one plane through a central axis. The device is attached to the machine frame 1 of a printing press. It initially contains a drive gear 2, which is connected to a machine-synchronous part of the drive of the printing press. The drive gear 2 is mounted on a shaft 3. The shaft 3 is supported on one side by means of a bearing 4 in the machine frame 1. On the opposite side of the shaft 3, a drive toothing 5 and a needle bearing 6 are provided side by side in the axial direction. The wedge connection 6 engages in an output element 7. The output element 7 is in principle constructed as a hollow cylindrical body, which is formed on the inside corresponding to the needle bearing 6 on the end of the shaft 3. A clamping device 8 is also provided on the output element 7. On the clamping device 8, a drive lever 9 is pivotable via a collar sleeve 10, e.g. attached via a roller bearing. The drive lever 9 leads to deflection gears for the initiation of a reciprocating movement of friction rollers in an inking unit of the printing press.

Die Klemmvorrichtung 8 gestattet die Ankoppelung des Antriebshebels 9 an unterschiedlichen Positionen bezüglich der Drehachse des Abtriebselements 7. Dadurch ergeben sich bei Rotation des Abtriebselements 7 Kurbelbewegungen mit unterschiedlichem Radius bzw. unterschiedlich großem Hub. Die Klemmvorrichtung ist konventionell gestaltet und beispielsweise als T-Stück in einer entsprechenden Nut ausgeführt. Das T-Stück kann an beliebiger Stelle der Nut mittels einer Schraube in der Bewegungsachse des Antriebshebels 9 geklemmt werden.The clamping device 8 allows the coupling of the drive lever 9 at different positions with respect to the axis of rotation of the output element 7. This results in crank movements with different radius or stroke with rotation of the output element 7. The clamping device is of conventional design and is designed, for example, as a T-piece in a corresponding groove. The T-piece can be clamped at any point in the groove by means of a screw in the axis of movement of the drive lever 9.

Weiterhin sind der Welle 3 im Bereich der Antriebsverzahnung 5 wenigstens drei Planetenräder 12 zugeordnet. Die Planetenräder 12 sitzen jeweils auf einem Lagerbolzen 13, die auf der der Klemmvorrichtung 8 gegenüberliegenden Seite an dem Abtriebselement 7 angeordnet sind. Die Planetenräder 12 kämmen schließlich außen mit der Innenverzahnung 15 eines Hohlrades 14. Das Hohlrad 14 ist ringförmig ausgebildet und weist auf der Außenseite einen Stellzahnkranz 16 auf. Weiterhin besitzt das Hohlrad 14 auf einer Seite einen Führungsring 22, der sich seitlich des Stellzahnkranzes 16 erstreckt.Furthermore, the shaft 3 in the area of the drive toothing 5 is assigned at least three planet gears 12. The planet gears 12 are each seated on a bearing pin 13 which is arranged on the output element 7 on the side opposite the clamping device 8. The planet gears 12 finally mesh on the outside with the internal toothing 15 of a ring gear 14. The ring gear 14 is ring-shaped and has an adjusting ring gear 16 on the outside. Furthermore, the ring gear 14 has on one side a guide ring 22 which extends laterally of the gear ring 16.

Die Zentrierung der Zahnradanordnung erfolgt über ein Lager 11, mittels dessen das Abtriebselement 7 in einem Gehäuseoberteil 18 geführt wird. Das Gehäuseoberteil 18 ist mittels eines Gehäuseunterteils 17 mit dem Maschinengestell 1 verbunden. Das Hohlrad 14 ist drehbar, aber gänzlich ohne Lager geführt Einerseits sitzt der Führungsring 22 des Hohlrades 14 drehbar in einem Zentrierbund 23, der sich als ringförmige Hinterdrehung seitlich des Lagersitzes am Gehäuseoberteil 18 erstreckt. Andererseits liegt das Hohlrad 14 mit der dem Führungsring 22 abgewandten Seite an einem Führungsbund 25 am Gehäuseunterteil 17 an. Die ganze Anordnung wird schließlich mittels des Gehäuseunterteils 17 am Maschinengestell 1 befestigt. Das Gehäuseunterteil 17 kann über das Lager 4 zur Mitte der Welle 3 zentriert werden.The gear arrangement is centered via a bearing 11, by means of which the output element 7 is guided in an upper housing part 18. The upper housing part 18 is connected to the machine frame 1 by means of a lower housing part 17. The ring gear 14 is rotatable, but is guided entirely without a bearing. On the one hand, the guide ring 22 of the ring gear 14 is rotatably seated in a centering collar 23 which extends as an annular backward rotation to the side of the bearing seat on the upper housing part 18. On the other hand, the ring gear 14 lies with the side facing away from the guide ring 22 against a guide collar 25 on the lower housing part 17. The whole arrangement is finally attached to the machine frame 1 by means of the lower housing part 17. The lower housing part 17 can be centered on the bearing 4 to the center of the shaft 3.

Im Gehäuseoberteil 18 ist eine Stellwelle 20 drehbar gelagert. Sie trägt ein Stellzahnrad 19, das mit der Stellverzahnung 16 des Hohlrades 14 kämmt. Auf dem anderen Ende der Stellwelle 20 ist ein Kettenrad 21 angeordnet, mit dem ein nicht dargestellter Kettentrieb verbunden ist.An actuating shaft 20 is rotatably mounted in the upper housing part 18. It carries an adjusting gear 19 which meshes with the adjusting teeth 16 of the ring gear 14. On the other end of the adjusting shaft 20, a chain wheel 21 is arranged, to which a chain drive, not shown, is connected.

Gehäuseoberteil 18 und Gehäuseunterteil 17 sind über einen Bund 24 zueinander ausgerichtet, mit mehreren Halteschrauben miteinander verbunden und über der Gehäuseunterteil 17 am Maschinengestell 1 befestigt.Upper housing part 18 and lower housing part 17 are aligned with one another via a collar 24, connected to one another with a plurality of retaining screws and fastened to the machine frame 1 via the lower housing part 17.

In Figur 2 ist die Vorrichtung als Schnitt in der Ebene der Planetenräder 12 durch die Darstellung nach Figur 1 gezeigt. Gut erkennbar ist die konzentrische Anordnung von Welle 3, Planetenrädern 12 und Hohlrad 14. Ebenso ist an der Oberseite des Hohlrades 14 das Stellzahnrad 19 in Eingriff mit der Stellverzahnung 16 gezeigt. Konzentrisch dazu liegt das Kettenrad 21. Die Befestigung ist an drei Punkten des Gehäuseoberteils 18 geschnitten. Das Gehäuseunterteil 17 und die Befestigungspunkte zum Maschinengestell 1 sind teilweise sichtbar.In Figure 2, the device is shown as a section in the plane of the planet gears 12 through the illustration of Figure 1. The concentric arrangement of shaft 3, planet gears 12 and ring gear 14 can be clearly seen. Likewise, on the top of ring gear 14, actuating gear 19 in engagement with adjusting toothing 16 is shown. The sprocket 21 is concentric with this. The attachment is cut at three points on the upper housing part 18. The lower housing part 17 and the attachment points to the machine frame 1 are partially visible.

Die Funktion ist wie folgt: Die Vorrichtung stellt ein Umlaufrädergetriebe dar. Das Abtriebselement 7 stellt den Steg des Umlaufrädergetriebes dar. Die Antriebsbewegung erfolgt über das Antriebszahnrad 2 von der Druckmaschine her. Die Bewegung wird im Folgenden von der Antriebsverzahnung an der Welle 3 auf die Planeten 12 und von diesen über die Lagerbolzen 13, mit entsprechender Untersetzung von beispielsweise 1:3 oder 1:4, auf den Steg bzw. das Abtriebselement 7 übertragen. Das Hohlrad 14 wird dabei jeweils über das Stellzahnrad 19 festgehalten. Durch Verdrehen des Hohlrades 14 mit dem Stellzahnrad 19, ausgehend vom Kettenrad 21 und der Stellwelle 20, ist eine Veränderung der Relativlage von Abtriebselement 7 und Antriebszahnrad 2 möglich. Das Hohlrad dreht sich dabei in seinem Sitz zwischen Gehäuseoberteil 18 und Gehäuseunterteil 17. Das Abtriebselement 7 dreht sich über die Nadellagerung 6 auf der Welle 3. Die Verstellung kann ferngesteuert erfolgen.The function is as follows: The device represents an epicyclic gear. The output element 7 represents the web of the epicyclic gear. The drive movement takes place via the drive gear 2 from the printing press. The movement is subsequently from the drive toothing on the shaft 3 to the planet 12 and from this via the bearing pin 13, with a corresponding reduction of, for example, 1: 3 or 1: 4, on the web or the output element 7 transmitted. The ring gear 14 is held in place by the setting gear 19. By turning the ring gear 14 with the setting gear 19, starting from the chain wheel 21 and the setting shaft 20, a change in the relative position of the output element 7 and the drive gear 2 is possible. The ring gear rotates in its seat between the upper housing part 18 and lower housing part 17. The output element 7 rotates via the needle bearing 6 on the shaft 3. The adjustment can be carried out remotely.
