Abstract

The cylinder drive includes two cylinders (01, 02) with friction gears (06, 07). The ratio of the radius (r06) of the friction gear of the first cylinder to a whole-number multiple of the radius (r07) of the friction gear of the second cylinder is less than 1.02 and greater than 1.0005. By this means, the friction torque produced by the process-related friction gear (03, 04) is approximately compensated by the additional friction torque of the second friction gear.

Description

Beim Antrieb von Zylindern oder Zylindergruppen mit separaten Servoantrieb z. B. in Satelliten (Abb. 3) können prozeßbedingt Abwicklungsunterschiede zwischen den Zylinderpaarungen auftreten. (Abb. 1-3, Pos. 1, 2). Diese Zylinderpaarungen haben unterschiedliche treibende Radien r1; r2 (Abb. 1, 2). Dadurch wird zwangsläufig, bei dem Prozeß bedingt erzwungenen phasengleichen Antrieb der Zylinder, vom Zylinder mit dem größeren treibenden Radius ein Reibmoment auf den Zylinder mit treibenden Radius ein Reibmoment auf den Zylinder mit dem kleineren treibenden Radius übertragen. Diese z. T. erheblichen Leistungsflüsse sind unerwünscht, da sie zu Asymmetrien in der Leistungsauslegung führen und z. B. bei einen 10er Satellit mit drei Antrieben pro Hälfte (Abb. 3) der Gegendruckzylinder mit großen Momenten gebremst werden muß.When driving cylinders or cylinder groups with separate servo drive z. B. in satellites ( Fig. 3) process-related processing differences between the cylinder pairs can occur. ( Fig. 1-3, items 1, 2). These cylinder pairs have different driving radii r1; r2 ( Fig. 1, 2). As a result, in the process of forced in-phase drive of the cylinders, a frictional torque is inevitably transmitted from the cylinder with the larger driving radius to the cylinder with driving radius to the cylinder with the smaller driving radius. This z. T. considerable power flows are undesirable because they lead to asymmetries in the power design and z. B. with a 10 satellite with three drives per half ( Fig. 3) the impression cylinder must be braked with large moments.

Nach dem bisherigen Stand der Technik waren die Satelliten insgesamt durch phasenstarre Zahnradgetriebe gekoppelt, so daß die Reibmomente als innere Momente nicht in Erscheinung getreten sind. Diese phasenstarren Getriebe bedingen jedoch eine aufwendige Kupplungs- und Registertechnik, die durch die Einzelantriebstechnik entfallen kann.According to the current state of the art, the satellites were completely through phase locked gear transmission, so that the frictional moments as internal moments have not appeared. However, these phase-locked gears require one elaborate coupling and register technology, which is eliminated by the individual drive technology can.

Bei einem Reibgetriebe mit den prozeßbedingten treibenden Radien r1 und r2 (Abb. 1, 2) wird ein kompensierendes Reibgetriebe mit den Radien rs1 und rs2 überlagert. In der Abb. 2 ist ein Beispiel dargestellt, bei dem r2 < r1. Das kompensierende Reibgetriebe wird daher so ausgelegt, daß rs1 < rs2 und unter Berücksichtigung, das durch r1, r2 erzeugt wird, dem Reibmoment rs1, rs2 entspricht und diese sich wechselseitig nahezu kompensieren.In the case of a friction gear with the process-related driving radii r1 and r2 ( Fig. 1, 2), a compensating friction gear with the radii rs1 and rs2 is superimposed. Fig. 2 shows an example where r2 <r1. The compensating friction gear is therefore designed in such a way that rs1 <rs2 and, taking into account that generated by r1, r2, corresponds to the friction torque rs1, rs2 and these almost mutually compensate each other.

Eine einfache und günstige Ausformung des Kompensations-Reibgetriebes ist die entsprechende Auslegung der Schmitzringe. Dabei wird der Schlupf so gewählt, daß die entstehende Relativbewegung innerhalb zulässiger Grenzen für die Dauerfestigkeit der Schmitzringoberfläche bleibt.A simple and inexpensive form of the compensation friction gear is appropriate design of the bearer rings. The slip is chosen so that the resulting relative movement within permissible limits for the fatigue strength of the  The bearer ring surface remains.

Der Erfindung liegt die Aufgabe zu Grunde eine Einrichtung zum Einstellen von Schmitzringen zu schaffen.The invention is based on the object of a device for setting Creating bear rings.

Bei der Ausformung eines Kompensations-Reibgetriebes als Schmitzringe mit unterschiedlichem Durchmesser (z. B. Schmitzring-Durchmesser am Gegendruckzylinder um 0,05% größer als am Gummituchzylinder) besteht die Problematik, daß die Größe der übertragenen Leistung stark von der Anstellung der Schmitzringe zueinander abhängt.When shaping a compensation friction gear as bearer rings with different diameters (e.g. bearer ring diameter on the impression cylinder by 0.05% larger than on the blanket cylinder) there is the problem that the size of the transmitted power strongly depends on the position of the bearer rings.

Um zu gewährleisten, daß diejenige Leistung über das Reibgetriebe zurückübertragen wird, die auch im Druckspalt übertragen wird (d. h. daß die von den Einzelantrieben benötigten Leistungen in etwa gleich groß sind), wird erfindungsgemäß die Anstellung der Schmitzringe zueinander während des Laufes der Maschine automatisch eingestellt, so daß die gemessenen Motorleistungen in etwa gleich groß sind.To ensure that the power is transferred back via the friction gear which is also transmitted in the pressure nip (i.e. that from the individual drives required power are approximately the same size), the employment of the invention Bearings set to each other automatically while the machine is running, see above that the measured engine powers are approximately the same size.

Meßgröße hierbei muß also nicht die Anstellung der Schmitzringe selbst sein, sondern es kann auch die Differenz der momentan benötigten Leistungen der Einzelantriebe herangezogen werden.Measured variable here does not have to be the setting of the bearer rings themselves, but it can also be the difference between the currently required powers of the individual drives be used.

Durch längeren Lauf der Maschine und auch dadurch, daß sich die Zylinder und die Gestelle u. U. unterschiedlich stark thermisch ausdehnen, kann sich die Schmitzring-Anstellung verändern.By running the machine for a long time and also because the cylinders and the Racks u. U. thermal expansion differently, the Change bearer ring position.

Diese führt im Fall unterschiedlicher Schmitzring-Durchmesser zu einer unkontrollierten Leistungsübertragung, so daß eine Über- oder Unterkompensation zu befürchten ist. Daneben kommt es aber auch zu einer unkontrolliert veränderten mechanischen Beanspruchung der Schmitzringe. Durch eine automatische Regelung der Schmitzring-Anstellung würde auch diese Beanspruchung keinen unkontrollierten Schwankungen mehr unterliegen.In the case of different bearer ring diameters, this leads to an uncontrolled Power transmission, so that over- or under-compensation is to be feared. In addition, there is also an uncontrolled change in the mechanical Stress on the bearer rings. By automatic regulation of the Bearer ring employment would also not make this stress uncontrolled Subject to fluctuations.
