Abstract

The circulating link chain has a chain links (4) with recesses in form of a teeth at lower surface, and a double toothed gear belt (3) on a straight longitudinal piece of the link chain having straight link chain pieces on entire length engages into the recess of the chain slider. The straight link chain pieces in the upper and lower branch of the circulating link chain intervenes at the same time.

Description

Die Erfindung betrifft umlaufende Ketten oder Gliederbänder, welche über selbsttätige Werkstückspannvorrichtungen, wie in DE 102 14 554 A1 beschrieben, verfügen und hohe Kräfte aufnehmen und exakte Vorschubbewegungen ausführen müssen.The invention relates to circulating chains or link belts, which via automatic workpiece clamping devices, as in DE 102 14 554 A1 described, have and absorb high forces and perform exact feed movements.

Bei den bisherigen Ketten erfolgt der Antrieb an einem der Umlenkpunkte. Dieser Antrieb hat den Nachteil, dass sich die Kette vor bzw. nach dem Antrieb dehnt oder sich aufbäumt und somit keine exakte Vorschubbewegung möglich ist.at the previous chains the drive takes place at one of the deflection points. This drive has the disadvantage that the chain before or after stretches the drive or rears up and thus no exact feed movement is possible.

Weiterhin sind diese Ketten nicht allseitig vorgespannt und rollengeführt, wie in DE 198 47 249 A1 dargestellt, so dass nur bestimmte Kräfte aufgenommen werden können.Furthermore, these chains are not biased on all sides and roll-guided, as in DE 198 47 249 A1 shown so that only certain forces can be absorbed.

Der Erfindung liegt die Aufgabe zugrunde, die oben beschriebenen Nachteile und Einschränkungen zu beseitigen und die umlaufende Kette mit dem Antrieb so zu verzahnen dass möglichst keine Dehnung in der Kette stattfinden kann und die Antriebskraft direkt und an mehreren Stellen eingeleitet wird.Of the Invention is based on the object, the disadvantages described above and restrictions to eliminate and interlock the circulating chain with the drive so that possible no stretching in the chain can take place and the driving force directly and in several places.

Diese Aufgabe wird erfindungsmäßig durch folgende Anordnung gelöst.These The object is erfindungsmäßig by the following Arrangement solved.

Ein doppeltverzahnter Zahnriemen greift in mehrere Kettenglieder ein, welche auf der Unterseite entsprechend ausgenommen sind. Der Eingriff kann gleichzeitig im Obertrum sowie im Untertrum der umlaufenden Kette erfolgen. Der Zahnriemen wird darüber hinaus über eine Andruckvorrichtung an die Unterseite des Kettengliedes angepresst, um eine Spielfreiheit und eine formschlüssige Kraftübertragung zu garantieren.One double-toothed toothed belt engages in several chain links, which are excluded on the bottom accordingly. The engagement can simultaneously in the upper run and in the lower run of the circulating Chain done. The timing belt is also a pressure device pressed against the underside of the chain link to a backlash and a form-fitting power transmission to guarantee.

Diese Art des Antriebes macht eine allseitig vorgespannte rollengeführte Kette notwendig. Das gleiche Prinzip ist auch mit Zahnstangensegmenten, welche an jedem Kettenglied angebracht sind, in Verbindung mit einem verspannten Doppelritzel möglich.These Type of drive makes a universally preloaded roller-guided chain necessary. The same principle is also true with rack segments attached to each chain link, in conjunction with a strained Double pinion possible.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass umlaufende Kette und Antrieb eine sich verzahnende Einheit bilden und die Krafteinleitung, über die Länge des doppelt verzahnten Zahnriemens, je nach Anforderung gestaltet werden kann. Eine Längenänderung der Kette bei Belastung wird deutlich reduziert, da die Kraft gleichmäßig an mehreren Stellen eingeleitet wird. Ebenso wird ein Umkehrspiel auf diese Weise ausgeschlossen, so dass die Voraussetzung für eine reversierende NC-Achse gegeben ist. Bei der Verwendung von 2 Antriebseinheiten kann die Kette zwischen den Antriebseinheiten noch zusätzlich kontrolliert verspannt werden.The particular advantages of the invention are that revolving chain and drive an interlocking unit form and the force application, over the length of double-toothed timing belt, designed according to the requirement can. A change in length The chain under load is significantly reduced, as the force evenly at several Jobs is initiated. Likewise, a backlash on this Excluded way, so the prerequisite for a reversing NC axis is given. When using 2 drive units the chain between the drive units can be additionally controlled be tense.

Durch die staubfreie Abdichtung ist weiterhin eine wichtige Voraussetzung für den Einsatz als reversierende NC-Achse geschaffen worden, im Gegensatz zu DE 198 47 249 A1 .Due to the dust-free seal, an important prerequisite for use as a reversing NC axis has been created, in contrast to DE 198 47 249 A1 ,

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im folgenden näher beschrieben.One embodiment The invention is illustrated in the drawings and will be described in more detail below.

Diese umlaufende Kette wird über einen Zahnriemen (3), welcher über ein Antriebsritzel (1) und ein Umlenkritzel (2) bewegt wird, angetrieben. Um eine formschlüssige Kraftübertragung zu gewährleisten wird der Zahnriemen (3) mit einer Andruckplatte (6) gegen die Gliederkette in die Verzahnung (5) gepresst. 1 a circumferential link chain consisting of chain links ( 4 ), with an inserted toothing ( 5 ), consists. This revolving chain is connected via a toothed belt ( 3 ), which via a drive pinion ( 1 ) and a deflecting pinion ( 2 ) is driven. To ensure a positive power transmission, the toothed belt ( 3 ) with a pressure plate ( 6 ) against the link chain in the toothing ( 5 ) pressed.
