Abstract

The printer cylinder (1) comprises a mounting which contains rings (11-13) inside one another. At least one ring (12) is eccentrically positioned so that when it turns it can displace the axle of the printer cylinder. While the sleeve is being changed, the ring is secured against turning, especially by being connected to the pin (2). The eccentric ring contains a further eccentric ring (17) mounted on rollers. The eccentric ring (12) is in the form of a bushing (18) to which a rod (19) is fixed pivot mounted on the pin of the printer cylinder. The bushing contains the first half (22) of a clutch (23) whose second half (26) is fixed to the end side of the pin. The first clutch half has a peripheral groove into which fits a fork (28) mounted in the bushing. <IMAGE>

Description

Die Erfindung betrifft einen Druckwerkszylinder einer Rollenrotationsdruckmaschine gemäß dem Oberbegriff des Anspruchs 1 bzw. 7. Insbesondere betrifft die Erfindung Formzylinder und Übertragungszylinder.The invention relates to a printing couple cylinder of a web-fed rotary printing press. In particular, the invention relates to forme cylinders and transfer cylinders.

Bei Rollenrotationsdruckmaschinen ist zur Erzielung einer guten Druckqualität eine konstante Linienkraft zwischen den die Bahn bedruckenden Zylindern erforderlich. Konstante Anstellkräfte werden auch zwischen dem Formzylinder und dem Übertragungszylinder gefordert. Zur Erfüllung dieser Bedingung muß der Achsabstand zwischen den gegeneinander angestellten Zylindern immer gleich sein. Die Zylinder sind hierfür mit Schmitzringen (z. B. DE-OS 2614792) ausgestattet. Bei Druckwerkszylindern, die mit Druckform- oder Übertragungsformhülsen arbeiten, darf sich an der Seite, an der die Hülse abgezogen oder aufgeschoben wird, kein Schmitzring befinden. Um mit derartigen Zylindern dennoch gute Druckergebnisse zu erzielen, werden an die Zylinderlagerungen, insbesondere hinsichtlich Spielfreiheit, große Anforderungen gestellt. Dies gilt auch für die Wandbüchsen, die die Zylinderlager aufnehmen. Üblicherweise sind diese Buchsen jedoch mit Spiel in der Maschinenseitenwand gelagert, da sie z. B. für die Druckan- und -abstellung verdrehbar sein müssen. Auch die Verschiebbarkeit von Wandbüchsen kann gefordert sein.In the case of web-fed rotary printing presses, a constant line force between the cylinders printing on the web is required to achieve good print quality. Constant contact forces are also required between the forme cylinder and the transfer cylinder. To meet this condition, the center distance between the cylinders positioned against each other must always be the same. For this purpose, the cylinders are equipped with bearer rings (e.g. DE-OS 2614792). For printing unit cylinders that work with printing form or transfer form sleeves, there must be no bearer ring on the side on which the sleeve is pulled off or pushed on. In order to achieve good printing results with such cylinders, great demands are made on the cylinder bearings, particularly with regard to freedom from play. This also applies to the wall liners that accommodate the cylinder bearings. Usually, however, these bushings are stored with play in the machine side wall, since they are e.g. B. must be rotatable for the print on and off. The movability of wall liners can also be required.

Der Erfindung liegt die Aufgabe zugrunde, Druckwerkszylinder zu schaffen, mit denen sich eine gute Druckqualität erzielen läßt.The invention has for its object to provide printing unit cylinders with which a good print quality can be achieved.

Diese Aufgabe wird bei gattungsgemäßen Druckwerkszylindern durch die Anwendung der Merkmale des kennzeichnenden Teils des Patentanspruchs 1 oder 7 gelöst. Die Druckwerkszylinder sind spielfrei bzw. spielarm in bzw. an den Seitenwänden des Druckwerks lagerbar. Sie weisen auch keine in der Seitenwand drehbar oder schiebbar zu lagernden Büchsen auf. Diese Büchsen können deshalb spielfrei in der Wand montiert oder sogar in der Wand geklemmt werden. Insgesamt ist hierdurch eine gute Druckqualität erzielbar. Weiterhin verändern bei einem Hülsenwechsel, d. h. bei einer Freilegung der Lagerung des Druckwerkszylinders, die Exzenter ihre Drehlage nicht, d. h. der Druckwerkszylinder behält bei einem Hülsenwechsel unverändert seine Position bei.This problem is solved in generic printing cylinder by the application of the features of the characterizing part of claim 1 or 7. The printing unit cylinders can be stored without play or with little play in or on the side walls of the printing unit. You point also no sleeves that can be rotated or pushed in the side wall. These bushings can therefore be mounted in the wall without play or even clamped in the wall. Overall, good print quality can be achieved in this way. Furthermore, the eccentrics do not change their rotational position when changing the sleeve, ie when the bearing of the printing unit cylinder is exposed, ie the printing unit cylinder remains in its position unchanged when changing the sleeve.

Weitere Vorteile und Merkmale ergeben sich aus den Unteransprüchen in Verbindung mit der Beschreibung.Further advantages and features result from the subclaims in connection with the description.

Die Erfindung soll nachfolgend an einigen Ausführungsbeispielen näher erläutert werden. In den zugehörigen Zeichnungen zeigt:

The invention will be explained in more detail below using a few exemplary embodiments. In the accompanying drawings:
Fig. 1
a transfer cylinder,
Fig. 2
a plate cylinder,
Fig. 3
a detail variant of Fig. 1, in sections.

In Fig. 1 ist als Druckwerkszylinder ein Übertragungszylinder 1 gezeigt, der mit seinen Zapfen 2, 3 in Seitenwänden 4, 5 eines Druckwerkes gelagert ist. Die Lagerung in der Seitenwand 5 wird, da nicht zum Gegenstand der Erfindung gehörig, nicht näher beschrieben. Der Zapfen 2 ist mittelbar in der Seitenwand 4 gelagert. Die Seitenwand 4 weist im Bereich des Zapfens 2 eine Öffnung 6 auf, die mit an der Seitenwand 4 angeordneten, quer zum Zapfen 2 verschiebbaren Schiebern 7, 8 verschlossen bzw. freilegbar ist. Eine Ausführung derartiger Schieber ist beispielsweise in der EP 0 277 545 B1 gezeigt. Eine Führung 9 für den Schieber ist angedeutet.In Fig. 1, a transfer cylinder 1 is shown as a printing unit cylinder, which is mounted with its pins 2, 3 in side walls 4, 5 of a printing unit. The storage in the side wall 5 is not described in detail since it is not part of the subject matter of the invention. The pin 2 is mounted indirectly in the side wall 4. The side wall 4 has an opening 6 in the region of the pin 2, which opening is closed or exposed with sliders 7, 8 arranged on the side wall 4 and displaceable transversely to the pin 2. An embodiment of such a slide is shown for example in EP 0 277 545 B1. A guide 9 for the slide is indicated.

Die Schieber 7, 8 nehmen im gezeichneten geschlossenen Zustand die Lagerung 10 des Zapfens 2 auf. Letztere enthält drei ineinanderliegende Ringe 11, 12, 13, die zueinander selbst gelagert sind. Der innere Ring 11 ist auf dem Zapfen 2 angeordnet und mittels eines zweireihigen Zylinderrollenlagers 14 im Ring 12 gelagert.The slider 7, 8 take the storage 10 of the pin 2 in the drawn closed state. The latter contains three rings 11, 12, 13 lying one inside the other, which are themselves supported with respect to one another. The inner ring 11 is arranged on the pin 2 and mounted in the ring 12 by means of a double row cylindrical roller bearing 14.

Letzterer wiederum ist mittels eines zweireihigen Nadellagers 15 im Ring 13 gelagert. Zur Lagerung der Ringe 11, 12, 13 ineinander können auch anderweitige Wälzlager oder auch Gleitlager zur Anwendung kommen, jedoch eignen sich Wälzlager recht gut zur Realisierung einer gewünschten spielfreien Lagerung. Der Ring 12 ist exzentrisch ausgebildet und vermag so bei seiner Drehung für die Druckan- und -abstellung des Übertragungszylinders 1 dessen Achse zu verschieben. Hierzu weist der Ring 12 eine zum Außenmantel exzentrische Bohrung 16 auf, in der das Zylinderrollenlager 14 aufgenommen wird. Vorteilhaft ist aber noch zwischen das Zylinderrollenlager 14 und den Ring 12 ein exzentrischer Ring 17 gesetzt, der der Grundeinstellung des Übertragungszylinders 1 dient. Im Ausführungsbeispiel ist der Ring 17 mit Preßsitz in der Bohrung 16 gelagert. Zur Verstellung des Rings 17 wird der Preßsitz mit einem nicht dargestellten Hydraulik-Preßverband aufgehoben. Die Verstellung selbst kann beispielsweise mittels eines dem Fachmann geläufigen Gewindespindeltriebes erfolgen. Der Ring 17 kann auch wälzgelagert im Ring 12 angeordnet sein.The latter in turn is supported in the ring 13 by means of a double row needle bearing 15. Other bearings or plain bearings can also be used to mount the rings 11, 12, 13 in one another, however, roller bearings are quite suitable for realizing a desired play-free bearing. The ring 12 is eccentric and is able to shift the axis of the transfer cylinder 1 when it rotates for the printing on and off. For this purpose, the ring 12 has a bore 16 which is eccentric to the outer jacket and in which the cylindrical roller bearing 14 is received. However, an eccentric ring 17 is also advantageously placed between the cylindrical roller bearing 14 and the ring 12, which serves for the basic setting of the transfer cylinder 1. In the exemplary embodiment, the ring 17 is press-fitted in the bore 16. To adjust the ring 17, the press fit is released with a hydraulic press fit, not shown. The adjustment itself can be carried out, for example, by means of a threaded spindle drive familiar to the person skilled in the art. The ring 17 can also be arranged in the ring 12 with roller bearings.

Der Ring 12 ist als Büchse 18 ausgeführt. Am Boden der Büchse 18 ist eine Stange 19 befestigt, die wiederum drehbar am Zapfen 2 gelagert ist. Sie trägt hierzu an ihrem Ende zwei Rillenkugellager 20, 21, die in einer Bohrung des Zapfens 2 aufgenommen sind. Statt der Rillenkugellager 20, 21 können auch andere Lager eingesetzt werden, die eine Axialkraft aufnehmen können. In der Büchse 18 ist weiterhin die erste Kupplungshälfte 22 einer Schaltkupplung 23 untergebracht. Die Kupplungshälfte 22 ist gegen die Kraft von Federn, beispeilsweise Tellerfedern 24, die sich am Boden der Büchse 18 abstützen, verschiebbar. Sie ist weiterhin mit einer Paßfeder 25 gegen Verdrehen gesichert. Die erste Kupplungshälfte 22 arbeitet mit einer an der Stirnseite des Zapfens 2 befestigten zweiten Kupplungshälfte 26 zusammen. An ihrem Außenmantel trägt die Kupplungshälfte 22 eine Umfangsnut 27, in die eine in der Büchse 18 gelagerte Schaltgabel 28 mit Gleitsteinen 29 eingreift. An der Schaltgabel 28 ist weiterhin ein Hebel 30 angeordnet, der vom Schieber 7 betätigbar ist.The ring 12 is designed as a sleeve 18. At the bottom of the sleeve 18, a rod 19 is attached, which in turn is rotatably mounted on the pin 2. For this purpose, it carries at its end two deep groove ball bearings 20, 21 which are received in a bore of the journal 2. Instead of the deep groove ball bearings 20, 21, other bearings can be used that can absorb an axial force. The first coupling half 22 of a clutch 23 is also accommodated in the bushing 18. The coupling half 22 is displaceable against the force of springs, for example cup springs 24, which are supported on the bottom of the bush 18. It is still with a parallel key 25 secured against twisting. The first coupling half 22 cooperates with a second coupling half 26 fastened to the end face of the pin 2. On its outer jacket, the coupling half 22 carries a circumferential groove 27 into which a shift fork 28 mounted in the bushing 18 engages with sliding blocks 29. A lever 30, which can be actuated by the slide 7, is also arranged on the shift fork 28.

Im Betriebszustand des Übertragungszylinders 1 befinden sich die Schieber 7, 8 in der in Fig. 1 gezeichneten Stellung und klemmen dabei die Lagerung 10 spielfrei am Ring 13. Um eine Gummituchhülse 31 vom Übertragungszylinder 1 herunter oder auf diesen durch die Öffnung 6 der Seitenwand 4 schieben zu können, muß der Zapfen 2 im Bereich der Öffnung 6 freigelegt werden. Hierzu werden die Schieber 7, 8 vom Zapfen 2 weggeschoben. Dabei gibt der Schieber 7 den Hebel 30 mitsamt der Schaltgabel 28 frei, wodurch die Tellerfedern 24 die Kupplungshälfte 22 gegen die Kupplungshälfte 26 drücken und damit die Schaltkupplung 23 einrücken. Die Schaltkupplung 23 ist als Reibungskupplung ausgebildet, d. h. die einander zugewandten Stirnseiten der Kupplungshälften 22, 26 tragen Reibbeläge. Die Schaltkupplung könnte beispielsweise auch als Klauen- oder Zahnkupplung ausgeführt werden. Die eingerückte Schaltkupplung 23 bewirkt, daß sich der exzentrisch ausgebildete Ring 12 beim Wechsel der Gummituchhülse 31, d. h. bei freigelegter Lagerung 10 nicht gegenüber dem Übertragungszylinder 1 verdrehen kann. Letzterer wiederum ist durch den Antrieb drehgesichert, mit dem der Zapfen 3, nicht dargestellt, verbunden ist. Weiterhin greift , nicht dargestellt, am Zapfen 3 eine Vorrichtung an, die den Übertragungszylinder 1 bei freigelegter Lagerung 10 fliegend gelagert in der Schwebe hält. Eine nunmehr über den freigelegten Zapfen 2 wechselbare Gummituchhülse 31 ist strichpunktiert dargestellt. Nach erfolgtem Hülsenwechsel werden die Schieber 7, 8 wieder in die gezeichnete Stellung gefahren. Dabei verändert der Übertragungszylinder dank der unveränderten Position des exzentrisch ausgebildeten Ringes 12 seine Lage nicht. Ebenso kann dadurch beim Schließen des Schiebers 8 ein Stellantrieb 32 für den Ring 12 in letzteren eingekuppelt werden. Die Verstellung des Ringes 12 dient, wie weiter oben bereits ausgeführt, der Druckan-und abstellung. Als Stellantrieb 32 kommt dafür im Ausführungsbeispiel ein entsprechend betätigtes Ritzel 33 zur Anwendung, das in ein Zahnsegment 34 der Büchse 18 eingreift. Die Stange 19 sichert auch die Büchse 18 gegen Verschieben. Zur Sicherung des Ringes 13 gegen Verschieben gegenüber dem Ring 12 im freigelegten Zustand des Lagers 10 ist am Ring 13 ein Mitnahmeblech 35 vorgesehen, das in eine Nut 36 des Ringes 12 eingreift. Die Sicherung könnte aber auch anderweitig erfolgen, beispielsweise dadurch, daß das Nadellager 15 mit axialer Festlegung ausgeführt ist.In the operating state of the transfer cylinder 1, the slides 7, 8 are in the position shown in FIG. 1 and clamp the bearing 10 free of play on the ring 13. To a rubber sleeve 31 from the transfer cylinder 1 or push it through the opening 6 of the side wall 4 to be able to, the pin 2 must be exposed in the region of the opening 6. For this purpose, the slider 7, 8 are pushed away from the pin 2. The slide 7 releases the lever 30 together with the shift fork 28, as a result of which the plate springs 24 press the clutch half 22 against the clutch half 26 and thus engage the clutch 23. The clutch 23 is designed as a friction clutch, ie the mutually facing end faces of the coupling halves 22, 26 carry friction linings. The clutch could also be designed as a claw or tooth clutch, for example. The engaged clutch 23 has the effect that the eccentrically formed ring 12 cannot rotate relative to the transfer cylinder 1 when the rubber blanket sleeve 31 is changed, ie when the bearing 10 is exposed. The latter in turn is secured against rotation by the drive with which the pin 3, not shown, is connected. Furthermore, not shown, acts on the pin 3, a device which holds the transfer cylinder 1 in floating position when the bearing 10 is exposed. A rubber blanket sleeve 31, which can now be exchanged over the exposed pin 2, is shown in dash-dot lines. After the sleeve has been changed, the slides 7, 8 are moved back into the position shown. Thanks to the unchanged position of the eccentrically designed ring 12, the transfer cylinder does not change its position. It can also be used for Closing the slide 8, an actuator 32 for the ring 12 can be engaged in the latter. The adjustment of the ring 12 serves, as already explained above, to switch the pressure on and off. A correspondingly actuated pinion 33, which engages in a toothed segment 34 of the bushing 18, is used as the actuator 32 for this purpose in the exemplary embodiment. The rod 19 also secures the sleeve 18 against displacement. To secure the ring 13 against displacement relative to the ring 12 in the exposed state of the bearing 10, a driving plate 35 is provided on the ring 13, which engages in a groove 36 of the ring 12. The backup could also be done otherwise, for example, that the needle bearing 15 is designed with an axial fixation.

In Fig. 2 ist als Druckwerkszylinder ein Formzylinder 37 gezeigt, der mit seinen Zapfen 38, 39 in Seitenwänden 40, 41 eines Druckwerkes lagert. Dabei wird die Lagerung 42 des Zapfens 38 von Schiebern 43, 44 aufgenommen, die schiebbar an der Seitenwand 40 angeordnet sind und in der gezeichneten Stellung eine Öffnung 62 der Seitenwand 40 verschließen. Die Lagerung 42 enthält zwei ineinander liegende, zueinander axial verschiebbare Ringe 45, 46. Die Ringe 45, 46 werden im Ausführungsbeispiel von einem zweireihigen Zylinderrollenlager 47 verkörpert. Zum Einsatz könnten aber auch anderweitige Wälzlager ohne axiale Festlegung, z. B. Nadellager, oder auch gleitgelagerte Ringe kommen. Von Vorteil ist bei Wälzlagern deren gute Möglichkeit der Einstellung auf Spielfreiheit. Dies erfolgt beispielsweise durch keglige Ausbildung der Bohrung des Ringes 45 sowie des zugehörigen Sitzes des Zapfens 38 und axiale Verstellung des Ringes 45. Der Ring 46 ist fest in einer Büchse 48 angeordnet. Im Boden der Büchse 48 ist zentrisch zum Mantel der Büchse 48 eine Bohrung angeordnet, durch die verschiebbar eine Stange 49 hindurchgeführt ist. Beiderseits der Bodenbohrung der Büchse 18 befinden sich auf der Stange 49 Druckfedern 50, 51, die sich gegen den Boden der Büchse 48 und Anschläge 52, 53 der Stange 49 abstützen. Die Stange trägt weiterhin zwei Rillenkugellager 54, 55, die in einer Bohrung des Zapfens 38 aufgenommen sind.In Fig. 2, a forme cylinder 37 is shown as a printing cylinder, which supports with its pin 38, 39 in side walls 40, 41 of a printing unit. The bearing 42 of the pin 38 is received by sliders 43, 44 which are slidably arranged on the side wall 40 and close an opening 62 of the side wall 40 in the position shown. The bearing 42 contains two rings 45, 46 which lie one inside the other and are axially displaceable with respect to one another. The rings 45, 46 are embodied in the exemplary embodiment by a double-row cylindrical roller bearing 47. Other rolling bearings without axial fixation, e.g. B. needle bearings, or slide bearings come. The advantage of rolling bearings is that they have a good possibility of adjusting to zero play. This takes place, for example, by conical formation of the bore of the ring 45 and the associated seat of the pin 38 and axial adjustment of the ring 45. The ring 46 is fixedly arranged in a sleeve 48. In the bottom of the sleeve 48, a bore is arranged centrally to the casing of the sleeve 48, through which a rod 49 is slidably guided. Both sides of the bottom bore of the sleeve 18 are on the rod 49 compression springs 50, 51, which are supported against the bottom of the sleeve 48 and stops 52, 53 of the rod 49. The rod also carries two deep groove ball bearings 54, 55 which are received in a bore of the pin 38.

Die Bedingungen für die Rillenkugellager 54, 55 sind die gleichen, wie die der Rillenkugellager 20, 21 in Fig. 1.The conditions for the deep groove ball bearings 54, 55 are the same as those of the deep groove ball bearings 20, 21 in FIG. 1.

Im Betriebszustand des Formzylinders 37 nehmen die Schieber 43, 44 die in Fig. 2 gezeichnete Stellung ein und klemmen die Büchse 48 spielfrei. Bei einer axialen Verschiebung des Formzylinders 37 verschiebt sich der Ring 45 gegenüber dem Ring 46, ohne daß die Büchse 48 in der Bohrung 56 der Schieber 43, 44 mitgeführt werden muß. Gleichzeitig wird bei dieser Verschiebung je nach Schieberichtung die Stange 49 im Boden der Büchse 48 verschoben und eine der Federn 50, 51 zusammengedrückt. Für einen Wechsel der Gummituchhülse werden die Schieber 43, 44 vom Zapfen 38 und der Lagerung 42 weggeschoben. Sie geben dabei die Büchse 48 frei, die von der zusammengedrückten Feder 50 oder 51 in ihre Nullage zurückgeschoben wird, wobei sich diese Feder 50 oder 51 entspannt. Bei einer neuerlichen Inbetriebnahme des Formzylinders 37 steht nunmehr wieder der volle Verschiebeweg des Ringes 45 gegenüber dem Ring 46 bzw. der volle Verschiebeweg des Formzylinders 37 zur Verfügung. Dieser Vorteil ist gegeben bei einer spielfreien, wahlweise auch geklemmten Lagerung der Büchse 48 in der Seitenwand. Der Wechsel der Druckformhülse 61, die in Fig. 2 strichpunkiert dargestellt ist, erfolgt in an sich bekannter Weise durch Schieben von dem bzw. auf den Formzylinder 37 durch die freigelegte Öffnung 62 der Seitenwand 40 über den freigelegten Zapfen 38. Der an seinen Zapfen 38 freigelegte Formzylinder 37 wird mittels einer nicht dargestellten Vorrichtung an der Seitenwand 41 fliegend gelagert in der Schwebe gehalten.In the operating state of the forme cylinder 37, the slides 43, 44 assume the position shown in FIG. 2 and clamp the bush 48 without play. When the forme cylinder 37 is axially displaced, the ring 45 moves relative to the ring 46 without the bush 48 having to be carried in the bore 56 of the slide 43, 44. At the same time, the rod 49 is displaced in the bottom of the sleeve 48 and one of the springs 50, 51 is compressed in this displacement, depending on the direction of sliding. For a change of the blanket sleeve, the slide 43, 44 are pushed away from the pin 38 and the bearing 42. They release the bush 48, which is pushed back into its zero position by the compressed spring 50 or 51, this spring 50 or 51 relaxing. When the forme cylinder 37 is started up again, the full displacement path of the ring 45 with respect to the ring 46 or the full displacement path of the forme cylinder 37 is again available. This advantage is given in the case of a bushing 48 which is free of play and optionally also clamped in the side wall. The change of the printing form sleeve 61, which is shown in dash-dotted lines in FIG. 2, takes place in a manner known per se by pushing from or onto the forme cylinder 37 through the exposed opening 62 of the side wall 40 via the exposed pin 38. The one on its pin 38 Exposed forme cylinder 37 is held in suspension on the side wall 41 by means of a device (not shown).

Das Lösungsprinzip der Fig. 2 (Anspruch 7) ist beispielsweise auch bei dem Druckwerkszylinder gemäß Fig. 1 anwendbar. So kann die Büchse 18' mit Anschlägen 57, 58 versehen sein, an denen sich Druckfedern 59, 60 abstützen, zwischen denen wiederum der Ring 13' plaziert ist (Fig. 3). Beim Hülsenwechsel, d. h. beim Wegfahren des Schiebers 8' bringen die Federn 59, 60 den Ring 13' wieder in eine Nullage zur Büchse 18', aus der er beim Verschieben der Büchse 18', d. h. bei einem Verschieben des Druckwerkzylinders, geraten war.The solution principle of FIG. 2 (claim 7) can also be used, for example, in the printing unit cylinder according to FIG. 1. Thus, the bushing 18 'can be provided with stops 57, 58 on which compression springs 59, 60 are supported, between which the ring 13' is placed (FIG. 3). When changing the sleeve, ie when moving the slide 8 ', the springs 59, 60 bring the ring 13' back into a zero position with respect to the bush 18 ', from which it came when the bush 18' was moved, ie when the printing unit cylinder was moved.

Der äußere Ring kann auch mittelbar, z. B. über einen benachbarten Ring, zum Zapfen in eine Nullstellung gebracht werden, beispeilsweise dadurch, daß der äußere Ring ohne Schiebefreiheitsgrad auf dem benachbarten Ring gelagert ist. An letzterm Ring greift dann die Vorrichtung zur Nulleinstellung an.The outer ring can also be indirect, e.g. B. over an adjacent ring, be brought into a zero position for pegging, for example in that the outer ring is mounted on the adjacent ring without a degree of freedom of sliding. The device for zeroing then acts on the latter ring.
