Description
Die Erfindung betrifft eine Vorrichtung zum Beseitigen von Zahnspiel zweier direkt zusammenwirkender Zahnräder gemäß dem Oberbegriff des Anspruches 1. The invention relates to a device for elimination of tooth play of two directly interacting gears according to the preamble of claim 1.
Aus der DE 28 15 534 C2 ist eine Einrichtung zum
Beseitigen von Zahnspiel eines Zahnradgetriebes,
insbesondere an Druckzylindern und Übertragungstrommeln
von Druckmaschinen bekannt. Hierbei wird ein erstes
Zahnrad mit einem Zahnsegment versehen und wirkt mit
einem zweiten Zahnrad zusammen. Durch Verstellung des
Zahnsegmentes bezüglich des ersten Zahnrades in
Umfangsrichtung wird das Zahnspiel zwischen erstem und
zweitem Zahnrad beseitigt.
Nachteilig an dieser Einrichtung ist, daß diese
Einrichtung nicht während der Drehbewegung der Zylinder
verstellt werden kann. DE 28 15 534 C2 discloses a device for eliminating tooth play in a gear transmission, in particular on printing cylinders and transfer drums of printing machines. Here, a first gearwheel is provided with a toothed segment and interacts with a second gearwheel. By adjusting the toothed segment with respect to the first gearwheel in the circumferential direction, the tooth play between the first and second gearwheels is eliminated.
A disadvantage of this device is that this device cannot be adjusted during the rotary movement of the cylinders.
Die DE 39 01 076 A1 zeigt eine Vorrichtung zum Ausgleich von Zahnspiel zwischen zwei miteinander im Eingriff stehenden Zahnrädern. Dabei ist eine zusätzliche, zu einem der Zahnräder parallel geschaltete Zahnscheibe bezüglich des zweiten Zahnrades während des Betriebes hydraulisch verstellbar. DE 39 01 076 A1 shows a device for compensation of tooth play between two engaged with each other stationary gears. Here is an additional one, too one of the gearwheels connected in parallel regarding the second gear during operation hydraulically adjustable.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Beseitigen von Zahnspiel zweier direkt zusammenwirkender Zahnräder, insbesondere von Zylindern einer Rotationsdruckmaschine, zu schaffen, wobei die Zylinder veränderbare Achsabstände aufweisen können, und dadurch entstehendes verändertes Zahnspiel durch die Vorrichtung während der Drehbewegung der Zylinder kompensiert werden kann. The invention has for its object a Device for eliminating tooth play two directly interacting gears, especially cylinders a rotary printing press, the Cylinders can have variable center distances, and resulting changed tooth play through the Device during the rotation of the cylinders can be compensated.
Diese Aufgabe wird durch die Merkmale des kennzeichnenden Teiles des Anspruches 1 gelöst. This task is characterized by the characteristics of the characterizing part of claim 1 solved.
Vorteilhaft ist, daß die erfindungsgemäße Vorrichtung
auch auf Zahnräder mit einem variablen Achsabstand
angewendet werden kann.
So ist es z. B. bei Tiefdruckmaschinen bzw.
Offsetdruckmaschinen nötig den Abstand zwischen Form- und
Druckzylinder bzw. Gummi- und Druckzylinder der
Dicke oder der Oberflächenbeschaffenheit des
Bedruckstoffes anzupassen. Damit wird das Zahnspiel
zwischen den entsprechenden Zahnrädern der Zylinder
vergrößert, was zu Schwingungen führen kann oder
verkleinert, wodurch die Zähne klemmen und
Beschädigungen auftreten können. Um diese Nachteile zu
vermeiden, ist es notwendig das Zahnspiel dem jeweiligen
Achsabstand der Zylinder anzupassen. Besonders
vorteilhaft ist, daß die erfindungsgemäße Vorrichtung
eine Einstellung des Zahnspieles während des Betriebes
der Druckmaschine ermöglicht. Somit ist eine
Rüstzeltverkürzung möglich und teure
Produktionsunterbrechungen sind nicht notwendig. It is advantageous that the device according to the invention can also be applied to gearwheels with a variable center distance.
So it is z. B. in gravure printing machines or offset printing machines necessary to adjust the distance between the forme and impression cylinder or rubber and impression cylinder of the thickness or the surface quality of the printing material. This increases the backlash between the corresponding gear wheels of the cylinder, which can lead to vibrations or reduce the size, which can cause the teeth to jam and cause damage. In order to avoid these disadvantages, it is necessary to adapt the tooth play to the respective center distance of the cylinders. It is particularly advantageous that the device according to the invention enables the tooth play to be adjusted during operation of the printing press. This makes it possible to shorten the set-up tent and expensive production interruptions are not necessary.
In dem dargestellten Beispiel ist durch besonders einfache, kostengünstige Mittel eine Verstellung eines Zahnsegmentes, welches als Beiläufer wirkt, möglich. In the example shown is by special simple, inexpensive means of adjusting a Tooth segment, which acts as a bypass, possible.
Durch Vermeidung von für diesen Anwendungsfall üblichen gefederten Beiläufern, wird eine erhöhte Belastung der Zahnräder vermieden. Die erfindungsgemäße Vorrichtung reduziert das Zahnspiel formschlüssig durch Verstellung des Zahnsegmentes in Umfangsrichtung und erzeugt somit keine zusätzlichen Kräfte auf die Zahnräder. By avoiding the usual for this application sprung shims, will increase the load on the Avoided gears. The device according to the invention reduces the backlash in a form-fitting manner by adjustment of the tooth segment in the circumferential direction and thus generates no additional forces on the gears.
Ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. An embodiment of the invention Device is shown in the drawing and is in following described in more detail.

In Seitengesellen 1 einer Rotationsdruckmaschine, z. B. einer Bogenrotationstiefdruckmaschine, ist in bekannter weise ein erster Zylinder 2, z. B. ein Formzylinder 2, ein zweiter Zylinder 3, z. B. ein Druckzylinder 3 und ein dritter Zylinder 4, z. B. eine Übergabetrommel 4 gelagert. Der Formzylinder 2 wirkt mit dem Druckzylinder 3 zusammen und diese beiden Zylinder 2, 3 weisen einen Achsabstand a23 auf, wobei dieser Achsabstand a23 variabel ist, d. h. verschiedenen Betriebszuständen anpaßbar ist. Die Übergabetrommel 4 wirkt mit dem Druckzylinder 3 zusammen. Diese Zylinder 2, 3, 4 sind mit Zapfen 6, 7, 8 versehen und auf diesen Zapfen 6, 7, 8 ist jeweils ein Zahnrad 9, 11, 12 drehsteif angebracht. Diese Zahnräder 9, 11, 12 übertragen ein zum Antrieb der Zylinder 2, 3, 4 notwendiges Drehmoment. Auf dem Zapfen 6 des Formzylinders 2 ist ein zweites Zahnrad 13 unabhängig vom Zapfen 6 drehbar gelagert. Dieses Zahnrad 13 weist eine Breie b13 auf und wirkt ebenfalls mit dem Zahnrad 11 des Druckzylinders 3 zusammen, wobei eine Breite b11 des Zahnrades 11 des Druckzylinders 3 ca. der Summe aus einer Breite b9 des ersten Zahnrades 9 und einer Breite b13 des zweiten Zahnrades 13 des Formzylinder 2 entspricht. In journeyman 1 of a rotary printing press, for. B. a sheet-fed rotogravure printing machine, is known in as a first cylinder 2, z. B. a forme cylinder 2, a second cylinder 3, e.g. B. a pressure cylinder 3 and a third cylinder 4, e.g. B. a transfer drum 4th stored. The forme cylinder 2 works with the impression cylinder 3 together and these two cylinders 2, 3 have one Center distance a23, this center distance a23 is variable, d. H. different operating conditions is customizable. The transfer drum 4 works with Printing cylinder 3 together. These cylinders 2, 3, 4 are provided with pins 6, 7, 8 and on these pins 6, 7, 8 is a gear 9, 11, 12 torsionally stiff appropriate. These gears 9, 11, 12 transmit a to Drive the cylinders 2, 3, 4 necessary torque. On the pin 6 of the forme cylinder 2 is a second Gear 13 rotatably supported independently of the pin 6. This gear 13 has a width b13 and acts also with the gear 11 of the impression cylinder 3 together, with a width b11 of the gear 11 of the Printing cylinder 3 approx. The sum of a width b9 of the first gear 9 and a width b13 of the second Gear 13 of the forme cylinder 2 corresponds.
An den Seitengesellen 1 ist weiterhin ein
Phasenverstellgetriebe 14 befestigt, welches mit den
Zylindern 2, 4 zusammenwirkt. Dieses
Phasenverstellgetriebe 14 ist als Zugmittelgetriebe,
insbesondere als Zahnriemengetriebe, ausgebildet. Es
besteht im wesentlichen aus einer ersten und einer
zweiten Riemenscheibe 16, 17, die über einen Zahnriemen
18 zusammenwirken. Die erste Riemenscheibe 16 ist
drehsteif mit dem zweiten, frei drehbaren Zahnrad 13 des
Formzylinders 2, die zweite Riemenscheibe 17 ist
drehsteif mit dem Zahnrad 12 der Übergabetrommel 4
verbunden. Das Zahnrad 12 der Übergabetrommel 4 und das
frei drehbare Zahnrad 13 bzw. das feste Zahnrad 9 des
Formzylinders 2 weisen ein gleich großes
Übersetzungsverhältnis wie die Riemenscheiben 16, 17 des
Phasenverstellgetriebes 14 auf. Im vorliegenden Fall
beträgt das Übersetzungsverhältnis 1 zu 1, wobei auch
jedes andere möglich ist.
Der Zahnriemen 18 wird mittels zweier Spannrollen 19, 21
von denen jeweils eine an einem Antriebstrum 22 und eine
an einem Leertrum 23 des Zahnriemens 18 wirkt. Diese
Spannrollen 19, 21 sind auf einer gemeinsamen Koppel 24
befestigt, wodurch ein Abstand a18 zwischen Leer- und
Antriebstrum 22, 23 festgelegt wird. Durch Verkürzen
dieses Abstandes a18 wird der Zahnriemen 18 gespannt.
Eine Veränderung der Lage bezüglich einer von
Formzylinder und Übergabetrommel 4 aufgespannten Ebene
der Koppel 24 bewirkt eine Veränderung der jeweiligen
Länge von Leer- bzw. Antriebstrum 22, 23 und somit eine
Lagerveränderung der Drehwinkel von den beiden
Riemenscheiben 16, 17 zueinander, d. h. eine Veränderung
der Phasenlage. On the journeyman 1 a phase adjustment 14 is also attached, which cooperates with the cylinders 2, 4. This phase adjustment gear 14 is designed as a traction mechanism gear, in particular as a toothed belt gear. It essentially consists of a first and a second pulley 16, 17, which interact via a toothed belt 18. The first pulley 16 is torsionally rigid with the second, freely rotatable gear 13 of the forme cylinder 2, the second pulley 17 is torsionally rigid with the gear 12 of the transfer drum 4. The gear 12 of the transfer drum 4 and the freely rotatable gear 13 or the fixed gear 9 of the forme cylinder 2 have the same transmission ratio as the pulleys 16, 17 of the phase adjustment mechanism 14. In the present case, the gear ratio is 1 to 1, but any other is also possible.
The toothed belt 18 is operated by means of two tensioning rollers 19, 21, one of which acts on a drive strand 22 and one on an empty strand 23 of the toothed belt 18. These tensioning rollers 19, 21 are fastened on a common coupling 24, as a result of which a distance a18 between the idle and drive strands 22, 23 is established. The toothed belt 18 is tensioned by shortening this distance a18. A change in the position with respect to a plane of the coupling 24 spanned by the forme cylinder and transfer drum 4 causes a change in the respective length of the idle or drive strand 22, 23 and thus a change in the bearing angle of rotation of the two pulleys 16, 17 to one another, ie a change in the Phase position.
Die Wirkweise der erfindungsgemäßen Vorrichtung wird an
einem Ausführungsbeispiel beschrieben.
In einer ersten bzw. zweiten Kontaktstelle 26, 27 der
Zahnräder 9, 11 bzw. der Zahnräder 13, 11 von Form- und
Druckzylinder 2, 3, sowie in einer Kontaktstelle 28 der
Zahnräder 11, 12 von Druckzylinder 3 und Übergabetrommel
4 besteht Zahnspiel. Mittels des Phasenverstellgetriebes
14 kann eine Drehwinkelverschiebung, d. h. eine
Verstellung in Umfangsrichtung, vom ersten Zahnrad 9 zum
zweiten Zahnrad 13 des Formzylinders 2 koaxial erfolgen,
was eine Beseitung des Zahnspieles zur Folge hat. Somit
wirkt das zweite Zahnrad 13 des Formzylinders 2 als
starrer Beiläufer.
Die Umfangsgeschwindigkeiten der Zahnräder 9, 11, 13 in
den Kontaktstellen 26, 27 von Form- und Druckzylinder 2,
3 sind und bleiben dabei gleich groß.
Wird der Achsabstand a23 von Form- und Druckzylinder 2,
3 verändert, ändert sich das Zahnsplel. Über die
Verstellung des Phasenverstellgetriebes 14 kann dies
auch bei drehenden Zylindern kompensiert werden. The mode of operation of the device according to the invention is described using an exemplary embodiment.
In a first or second contact point 26, 27 of the gear wheels 9, 11 or the gear wheels 13, 11 of the form and pressure cylinder 2, 3, and in a contact point 28 of the gear wheels 11, 12 of the pressure cylinder 3 and transfer drum 4, there is tooth play. By means of the phase adjustment gear 14, a rotation angle shift, ie an adjustment in the circumferential direction, can take place coaxially from the first gear 9 to the second gear 13 of the forme cylinder 2, which results in the elimination of the tooth play. Thus, the second gear 13 of the forme cylinder 2 acts as a rigid follower.
The peripheral speeds of the gears 9, 11, 13 in the contact points 26, 27 of the plate and impression cylinders 2, 3 are and remain the same.
If the center distance a23 of the form and pressure cylinder 2, 3 is changed, the tooth splice changes. This can also be compensated for when the cylinders are rotating by adjusting the phase adjustment gear 14.
Das frei drehende Zahnrad 13 des Formzylinders 2 kann natürlich auch nur als Zahnsegment ausgebildet sein, wenn Zahnspielfreiheit nur an einer Stelle oder in einem Bereich des Umfangs gefordert wird. The freely rotating gear 13 of the forme cylinder 2 can of course, only be designed as a tooth segment, if there is no backlash in one place or in one Range of scope is required.
Das dritte Zahnrad 12 muß nicht zum Antrieb eines
Zylinders 4 dienen, sondern kann natürlich auch eine
eigene, zylinderunabhängige Lagerung aufweisen.
Auch müssen die Riemenscheiben 16, 17 des
Phasenverstellgetriebes 18 nicht direkt mit den
Zahnrädern 12, 13 der Zylinder 2, 4 verbunden sein, es
sind beliebige Zwischenräder und auch andere Durchmesser
möglich. Hierbei ist aber gemeinsam, daß die Zahnräder
12, 13 der Zylinder 2, 4 und eventuell Zahnräder des
Verstellgetriebes 18 in den Kontaktstellen 26, 27 von
Form- und Druckzylinder 2, 3 gleich große
Umfangsgeschwindigkeiten erzeugen.
Die Koppel 24 ist nach erfolgter Stellbewegung starr,
nicht gefedert, z. B. mittels Gewindespindel,
angeordnet. Somit wird das Zahnspiel formschlüssig
beseitigt.
The third gear 12 does not have to serve to drive a cylinder 4, but can of course also have its own cylinder-independent storage.
Also, the pulleys 16, 17 of the phasing mechanism 18 do not have to be connected directly to the gears 12, 13 of the cylinders 2, 4, any intermediate wheels and other diameters are possible. What is common here, however, is that the gears 12, 13 of the cylinders 2, 4 and possibly gears of the adjusting gear 18 in the contact points 26, 27 of the forme and impression cylinders 2, 3 produce the same circumferential speeds.
The coupling 24 is rigid after the adjusting movement, not sprung, for. B. arranged by means of a threaded spindle. The tooth play is thus eliminated in a form-fitting manner.
