Description

Die Erfindung betrifft eine Einrichtung zur Getriebezugtrennung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for gear train separation according to the preamble of claim 1.

Eine Einrichtung zur Getriebezugtrennung ist aus der deutschen Patentschrift 4 141 817 bekannt. In dieser Einrichtung ist eine ringförmige Entriegelungsvorrichtung in Form einer Hydraulikkupplung zur Aufhebung der Klemmung zwischen einem Hauptzahnrad und einem Zahnradring vorgesehen. Die Hydraulikkupplung wirkt auf Spanneinrichtungen, die die Klemung mittels Federn herstellen. Die Einrichtung ist relativ großvolumig gebaut.A device for gear train separation is known from German Patent 4 141 817. In this device, an annular unlocking device is provided in the form of a hydraulic clutch to release the clamping between a main gear and a gear ring. The hydraulic coupling acts on tensioning devices that create the clamping by means of springs. The facility has a relatively large volume.

Einrichtungen dieser Art werden beispielsweise in Bogenrotationsdruckmaschinen eingesetzt, um eine Umstellung für Betriebsarten im sogenannten Schöndruck oder Schön- und Widerdruck zu ermöglichen, wobei die Umstellung eine Verstellung von Druckwerken relativ zueinander erfordert.Devices of this type are used, for example, in sheet-fed rotary printing presses in order to enable a changeover for operating modes in so-called straight printing or face and back printing, the changeover requiring an adjustment of printing units relative to one another.

Ziel der Erfindung ist, eine Einrichtung zur Getriebezugtrennung kompakter zu gestalten, die als Baueinheit einsetzbar ist.The aim of the invention is to make a device for gear train separation more compact, which can be used as a structural unit.

Aufgabe der Erfindung ist es, eine Einrichtung zur Getriebezugtrennung in kompakter Bauform bei verbesserten Haltekräften und erhöhter Funktionssicherheit zu beschreiben.The object of the invention is to describe a device for gear train separation in a compact design with improved holding forces and increased functional reliability.

Die Aufgabe wird nach dem Kennzeichen des Patentanspruchs 1 gelöst. Der Vorteil der neukonzipierten Einrichtung zur Getriebezugtrennung ist die erhöhte Haltekraft der Einrichtung bei gleichzeitig äußerst kompakter Konzeption. Außerdem ist die Einrichtung in der Lage den abgetrennten Teil des Antriebszuges bei der Verdrehung des anderen Antriebzugteiles festzuhalten, so daß eine zusätzliche Bremse eingespart wird. Vor allem ist es nicht mehr erforderlich Stützkräfte in eines der Zahnräder einzuleiten, um die Klemmung aufzuheben. Durch diese Wirkungsweise wird die Genauigkeit bei der Umstellung weiter erhöht. Außerdem erhöhen diese Maßnahmen die Funktionssicherheit der Einrichtung nicht unerheblich. Weitere Vorteile ergeben sich aus den Merkmalen der Unteransprüche.The object is achieved according to the characterizing part of patent claim 1. The advantage of the newly designed device for gear train separation is the increased holding force of the device with an extremely compact design. The facility is also able to separate part of the drive train to hold the rotation of the other drive train part, so that an additional brake is saved. Above all, it is no longer necessary to introduce supporting forces into one of the gearwheels in order to release the clamping. This mode of action further increases the accuracy during the changeover. In addition, these measures not insignificantly increase the functional reliability of the facility. Further advantages result from the features of the subclaims.

In Figur 1 ist auf einem Wellenzapfen 1, der mit einem Antriebszahnrad 2 verbunden ist, ein gegenüber diesem Wellenzapfen 1 verdrehbares Abtriebszahnrad 3 dargestellt. Auf dem Ende des Wellenzapfens 1 ist eine Hydraulikkupplung 4 angeordnet, die mit einer Klemmeinrichtung 5 zur Befestigung des Abtriebszahnrades 3 auf dem Wellenzapfen 1 verbunden ist. Die Hydraulikkupplung 5 besteht aus einem ringförmigen Gehäuse 7 und einem darin verschiebbar gelagerten ringförmigen Kolben 8. In den Ringraum zwischen Kolben 8 und Gehäuse 7 ist Druckmittel zuführbar. Der Kolben 8 ist mit einem gestellfest angeordneten Deckel 9 verbunden, der mittels eines Drucklagers 6 drehbar auf dem Ende des Wellenzapfens 1 gelagert ist. An dem Gehäuse 7 der Hydraulikkupplung 4 ist ein Greifring 10 angeordnet. Der Greifring 10 ist mit einer Schaltfläche 10A gegenüber der Klemmeinrichtung 5 angeordnet. Die Klemmeinrichtung 5 besteht aus einer flachen, ringförmigen Feder 11, einem Druckring 12, und einem Betätigungsring 13. Die Einheit ist ringförmig ausgebildet ist und auf dem Wellenzapfen 1 in axialer Richtung unverschiebbar aufgesetzt und mittels des Drucklagers 6 vorgespannt. An dem Abtriebszahnrad 3 ist zur Klemmeinrichtung 5 gewandt eine Reihe von biegbaren Klemmelementen 14 angeordnet. Die Klemmelemente 14 liegen auf einer Klemmfläche K an dem Wellenzapfen 1 an. Zwischen dem Druckring 12 und den biegbaren Klemmelementen 14 liegende Feder 11 erzeugt durch Axialbewegung eines Schaltelementes 15 eine Radialbewegung an den Klemmelementen 14.
In Figur 1 sind zwei Varianten für derartige Schaltelemente 15 in der Klemmeinrichtung 5 dargestellt. Zum einen kann ein Schaltelement in Form eines Pakets von tellerfederartigen Ringelementen 15.1 ausgebildet sein. Zum anderen kann das Schaltelement in Form eines einzigen aus einer ringförmigen, schrägstehenden Wand bestehenden Federelementes 15.2 ausgebildet sein. Die Schaltelemente 15.1, 15.2 liegen mit der Innenseite ihrer Ringflächen an einem Anschlag 16 auf dem Abtriebszahnrad 3 an. Die Außenseite der Ringflächen liegt an einem Anschlag des Betätigungsrings 13 an. Durch Schalten der Hydraulikkupplung 4 wird die Schräglage der Schaltelemente 15.1, 15.2 gegenüber den Klemmelementen 14 verändert, wodurch diese gegenüber dem Wellenzapfen 1 gelöst bzw. freigegeben werden. Funktionell Ist die Vorspannung der Klemmung durch Anpressen des Deckels 9 gegen das Drucklager 6 und den Betätigungsring 13 erzeugt. Beim Trennen des Getriebezuges wird der Betätigungsring 13 mittels der Hydraulikkupplung 4 vom Abtriebszahnrad 3 weg bewegt. Dabei stützt sich der Kolben 8 mit einer Schaltfläche 8A am Druckring 12 und das Gehäuse 10 mit der Schaltfläche 10A am Betätigungsring 13 ab. Dadurch werden die Schaltelemente 15.1, 15.2 in ihrer Schräglage weiterbewegt. Durch damit einhergehend Durchmesseränderung an den Schaltelementen 15.1, 15.2 wird die die Anpressung der Klemmelemente 14 zum Wellenzapfen 1 gelöst bzw. verringert. Zum erneuten Klemmen der Einrichtung wird die Kraft der Hydraulikkupplung 4 aufgehoben, wodurch sich die Klemmelemente 14 unter der Kraft der Feder 11 über den Betätigungsring 13 wieder mit dem Wellenzapfen 1 verbinden und die Schaltelemente 15.1, 15.2 sich dabei aufrichten.
In FIG. 1, an output gear 3 which is rotatable relative to this shaft journal 1 is shown on a shaft journal 1 which is connected to a drive gear 2. A hydraulic coupling 4 is arranged on the end of the shaft journal 1 and is connected to a clamping device 5 for fastening the driven gear 3 on the shaft journal 1. The hydraulic clutch 5 consists of an annular housing 7 and an annular piston 8 slidably mounted therein. Pressure medium can be fed into the annular space between the piston 8 and the housing 7. The piston 8 is connected to a cover 9 which is fixed to the frame and which is connected by means of a Thrust bearing 6 is rotatably mounted on the end of the shaft journal 1. A gripping ring 10 is arranged on the housing 7 of the hydraulic clutch 4. The gripping ring 10 is arranged with a button 10A opposite the clamping device 5. The clamping device 5 consists of a flat, ring-shaped spring 11, a pressure ring 12, and an actuation ring 13. The unit is of ring-shaped design and is placed on the shaft journal 1 so that it cannot move in the axial direction and is preloaded by means of the pressure bearing 6. A series of bendable clamping elements 14 is arranged on the driven gear 3 facing the clamping device 5. The clamping elements 14 rest on a clamping surface K on the shaft journal 1. Spring 11 lying between the pressure ring 12 and the bendable clamping elements 14 generates a radial movement on the clamping elements 14 by axial movement of a switching element 15.
1 shows two variants for such switching elements 15 in the clamping device 5. On the one hand, a switching element can be designed in the form of a packet of plate spring-like ring elements 15.1. On the other hand, the switching element can be designed in the form of a single spring element 15.2 consisting of an annular, inclined wall. The switching elements 15.1, 15.2 lie with the inside of their ring surfaces against a stop 16 on the driven gear 3. The outside of the ring surfaces lies against a stop of the actuating ring 13. By switching the hydraulic clutch 4, the inclined position of the switching elements 15.1, 15.2 with respect to the clamping elements 14 is changed, as a result of which they are released or released with respect to the shaft journal 1. Functionally, the pretension of the clamping is generated by pressing the cover 9 against the thrust bearing 6 and the actuating ring 13. When the gear train is separated, the actuating ring 13 is moved away from the driven gear 3 by means of the hydraulic clutch 4. The piston 8 is supported with a button 8A on the pressure ring 12 and the housing 10 with the button 10A on the actuating ring 13. As a result, the switching elements 15.1, 15.2 are moved further in their inclined position. The associated change in diameter on the switching elements 15.1, 15.2 releases or presses the clamping elements 14 against the shaft journal 1 or decreased. To reclamp the device, the force of the hydraulic clutch 4 is released, as a result of which the clamping elements 14 reconnect to the shaft journal 1 under the force of the spring 11 via the actuating ring 13 and the switching elements 15.1, 15.2 straighten up in the process.

In Figur 2 ist eine vergleichbare Vorrichtung dargestellt. Hierbei ist die Klemmung mittels einer Keilfläche erzeugt. Dazu ist ein Betätigungsring 17 in Ringform mit einer inneren Konusfläche 18 versehen, die mit einer in entsprechendes Konusform versehenen Außenfläche von Klemmelemente 19 am Abtriebszahnrad 3 zusammenarbeitet. Diese liegen auf einer Klemmfläche K am Wellenzapfen 1 an. Die Vorspannung wird mittels einer wellenförmigen Federanordnung 20 erzeugt. Die Vorspannkraft der Feder 20 kann mittels der ringförmigen Hydraulikkupplung 4 aufgehoben werden, wodurch sich die Klemmung des Abtriebszahnrades 3 auf dem Wellenzapfen 1 löst.A comparable device is shown in FIG. Here, the clamping is generated by means of a wedge surface. For this purpose, an actuating ring 17 in the form of a ring is provided with an inner conical surface 18 which cooperates with an outer surface of clamping elements 19 on the driven gear 3 provided in a corresponding conical shape. These rest on a clamping surface K on the shaft journal 1. The preload is generated by means of a wave-shaped spring arrangement 20. The biasing force of the spring 20 can be canceled by means of the annular hydraulic clutch 4, whereby the clamping of the driven gear 3 on the shaft journal 1 is released.

Die beiden Betriebszustände sind in Figur 2 beispielhaft dargestellt. In der oberen Bildhälfte ist das Abtriebszahnrad 3 geklemmt, in der unteren Bildhälfte gelöst. Dabei wird deutlich, daß die Hydraulikkupplung 4 im Ruhezustand am Deckel 9 gestelltfest angeordnet, aber berührungsfrei zur Klemmeinrichtung 5 gehaltert ist. Im Schaltzustand, dh. bei Trennung der beiden Zahnräder 2, 3, liegen die Schaltflächen 8A, 10A an der Klemmeinrichtung 5 an, erhöhen deren Vorspannung und entlasten dabei den Betätigungsring 17 bzw. die Klemmelemente 19. Hier ist auch gut erkennbar, daß in diesem Zustand der Wellenzapfen 1 fest mit dem Deckel 9 und damit auch mit dem Maschinengestell verbunden ist. Das Antriebszahnrad 2 ist damit samt dem angekoppelten Getriebe blockiert.The two operating states are shown as examples in FIG. 2. The output gear 3 is clamped in the upper half of the picture and released in the lower half of the picture. It is clear that the hydraulic clutch 4 is arranged stationary on the cover 9 in the idle state, but is held contact-free to the clamping device 5. In the switching state, ie. when the two gears 2, 3 are separated, the buttons 8A, 10A rest on the clamping device 5, increase their pretension and thereby relieve the actuating ring 17 or the clamping elements 19. Here it is also clearly visible that the shaft journal 1 is fixed in this state is connected to the lid 9 and thus also to the machine frame. The drive gear 2 is blocked together with the coupled gear.

In Figur 3 ist eine Variante der Erfindung nach Figur 1 dargestellt, wobei hier die Vorspannung eies konusförmigen Betätigungsringes 21 gegen über von Klemmelementen 22 am Abtriebszahnrad 3 mittels einer tellerfederartigen, ringförmigen Feder 23 erzeugt wird. Die Klemmelemente 22 liegen auf einer Klemmfläche K am Wellenzapfen 1 an. In gleicher Weise kann für diese Ausführungsform auch ein Federpaket aus zwei oder mehr Tellerfedern 23, auch in unterschiedlicher Orientierung zueinander, eingesetzt werden. Die Auswahl wird von der erforderlichen Federcharakteristik bestimmt. Die Klemmung des Abtriebszahnrades 3 wird durch Belastung mittels der ringförmigen Hydraulikkupplung 4 an der Tellerfeder 23 über den Druckring 24 und den Betätigungsring 21 aufgehoben.FIG. 3 shows a variant of the invention according to FIG. 1, in which case the preload of a conical actuating ring 21 is generated with respect to the clamping elements 22 on the driven gear 3 by means of an annular spring 23 in the form of a plate spring. The clamping elements 22 rest on a clamping surface K on the shaft journal 1. In the same way for this embodiment a spring assembly consisting of two or more disc springs 23, also in different orientations with respect to one another, can be used. The selection is determined by the required spring characteristics. The clamping of the driven gear 3 is released by loading by means of the annular hydraulic clutch 4 on the plate spring 23 via the pressure ring 24 and the actuating ring 21.

In Figur 4 ist eine weitere Variante zu sehen, wobei die Verriegelung des Abtriebszahnrades 3 mit dem Wellenzapfen 1 über eine axial wirkende Feinzahnkupplung 25 erzeugt wird. Die Feinzahnkupplung 25 ist ringförmig an einem Betätigungsring 26 angeordnet und greift in ein Gegenstück am Abtriebszahnrad 3 ein. Die Entriegelung erfolgt durch die ringförmige Hydraulikkupplung 4 an der Außenseite des Betätigungsringes 26 durch Axialbewegung. Dabei hebt die Feinverzahnung 25 aus, so daß das Abtriebszahnrad 3 frei drehbar ist.A further variant can be seen in FIG. 4, the locking of the driven gear 3 with the shaft journal 1 being produced via an axially acting fine tooth coupling 25. The fine tooth coupling 25 is arranged in a ring on an actuating ring 26 and engages in a counterpart on the driven gear 3. Unlocking takes place through the annular hydraulic clutch 4 on the outside of the actuating ring 26 by axial movement. The fine toothing 25 lifts out, so that the driven gear 3 is freely rotatable.

Allgemein ist zu bemerken, daß die Klemmelemente 14, 19, 22, 25 wenigstens in axialer Richtung geschlitzt sein müssen, um die erforderliche Radialbewegung ausführen zu können. Zur Erhöhung der Betriebssicherheit kann die auf dem Wellenzapfen 1 liegende Klemmfläche K profiliert sein, z.B. mit einer schmalen Nut. Damit ist die Sicherheit beim Schalten der Klemmung durch entweichen der Luft gewährleistet.In general, it should be noted that the clamping elements 14, 19, 22, 25 must be slotted at least in the axial direction in order to be able to carry out the required radial movement. To increase operational safety, the clamping surface K lying on the shaft journal 1 can be profiled, e.g. with a narrow groove. This ensures the safety when switching the clamp through the escape of air.

Weiterhin kann das Abtriebszahnrad 3 zum Antriebszahnrad 2 hin eine Nut aufweisen, In die vom Antriebszahnrad 2 aus ein Stift eingreift. Dieser wirkt mit einem Anschlag im Abtriebszahnrad 3 zusammen, um den maximalen Verdrehwinkel zu begrenzen.Furthermore, the driven gear 3 can have a groove toward the drive gear 2, into which a pin engages from the drive gear 2. This interacts with a stop in the output gear 3 in order to limit the maximum angle of rotation.

Die Vorrichtung nach den beschriebenen Darstellungen weisen insgesamt eine verbesserte Klemmung des zu lösenden Abtriebszahnrades 3 mit dem Wellenzapfen 1 auf. Insbesondere ist die Klemmung durch die Anordnung direkt am Wellenzapfenl sehr kompakt und weist trotzdem die erforderlichen Haltekräfte für die Obertragung einer hohen Antriebsleistung auf. Durch die verringerte Baugröße sind an der ringförmigen Hydraulikkupplung 4 sehr günstige Verhältnisse bei der Abdichtung und bei der Zuführung von Druckmitteln erreicht.The device according to the illustrations described have an overall improved clamping of the driven gear 3 to be released with the shaft journal 1. In particular, the clamping is very compact due to the arrangement directly on the shaft journal and still has the necessary holding forces for the transmission of a high drive power. Due to the reduced size, there are very favorable conditions on the annular hydraulic clutch 4 Sealing and when pressure medium is supplied.

Die Vorrichtung ist vorteilhaft in Bogenrotationsdruckmaschinen mit Bogenwendung einsetzbar. Insbesondere dann wird sie eingesetzt werden, wenn aus Raumerfordernissen bzw. technologischen Gründen zur Antriebsverlagerung zwischen verschiedenen Ebenen Zwischenzahnräder mit kleinerem Durchmesser neben den großen Hauptantriebsrädern eingesetzt werden.The device can advantageously be used in sheet-fed rotary printing machines with sheet turning. In particular, it will be used if intermediate gears with a smaller diameter are used in addition to the large main drive gears for space requirements or technological reasons for shifting the drive between different levels.

Die Vorrichtung stellt die Erfindung in einem begrenzten Aspekt dar und ist unter Auslegung des Patentanspruches auch anders ausführbar.The device represents the invention in a limited aspect and can also be carried out differently by interpreting the patent claim.
