Description

Es gibt an Bearbeitungsmaschinen Exzenter, die fest mit den Wellen verbunden sind und sich bei Rückdrehung der Wellen mitdrehen. Es besteht vielfach der Wunsch, die von den Exzentern ausgelöste Bewegung nicht rückgängig zu machen, wohl aber andere, mit der Exzenterwelle gekuppelte Bewegungen, ohne innerhalb der Maschine Trennungselemente, z. B. Kupplungen, eingebaut zu haben. Bisher bestand keine Möglichkeit, diese Rückdrehung durchzuführen, ohne auch die Bewegung, die durch den Exzenter ausgelöst wurde, zurückzunehmen, da der Exzenter immer mit der Welle fest verbunden war und ohne Trennungselemente somit mit zurückgeführt wurde.There are eccentrics on machine tools that are firmly attached to the shafts are connected and rotate when the shafts reverse. It exists in many ways the desire not to reverse the movement triggered by the eccentrics, but other movements coupled with the eccentric shaft, without within the Machine separation elements, e.g. B. Couplings to have installed. So far it existed no way to do this reverse rotation without also doing the movement that was triggered by the eccentric to take back, since the eccentric always with the The shaft was firmly connected and was therefore returned with no separating elements.

Diese Erfindung besteht demgegenüber darin, daß der Exzenter lose auf der Exzenterwelle sitzt und durch einen Mitnehmer und eine Feder mit dieser kraftschlüssig verbunden ist. Hierdurch wird der Vorteil erreicht, daß eine Rückdrehung möglich ist, ohne daß der Exzenter bewegt wird und damit die von ihm eingeleitete Bewegung rückgängig gemacht wird. Es wird auch eine zu weite Rückdrehung verhindert, trotzdem sämtlicheTeile kraftschlüssigverbunden bleiben. Dieses wird dadurch erreicht, daß ein fest mit der Exzenterwelle verbundener Stellring mit einem Mitnehmer in eine Aussparung eingreift und die Größe dieser Aussparung die Größe der möglichen Rückdrehung begrenzt.This invention, on the other hand, consists in that the eccentric is loose sits on the eccentric shaft and through a driver and a spring with this is positively connected. This has the advantage that a reverse rotation is possible without the eccentric being moved and thus the one initiated by it Movement is reversed. It is also prevented from turning back too far, nevertheless all parts remain positively connected. This is achieved by that an adjusting ring firmly connected to the eccentric shaft with a driver in a recess engages and the size of this recess the size of the possible Reverse rotation limited.

Die Erfindung ist in den Abb. i, 2 und 3 beispielsweise dargestellt. -Es zeigt Abb. i die Seitenansicht mit der Exzenterwellew, dem damit fest verbundenen Stellring a mit Mitnehmer c, der in die Aussparung h im Exzenterring b eingreift. Ferner zeigt die Abb. i die Feder f, den Ringbügel g und den Anschlag e am Exzenterring; Abb.2 die Axialansicht mit dem -Mitnehmernocken mit Bohrung d, der am Stellring 'a befestigt ist, wie auch den Mitnehmer c, der in der Aussparung h des Exzenterringes b liegt. Ferner zeigt die Abb. 2 die Feder f, den Ringbügel g und den Anschlag e am Exzenterring; Abb. 3 den Schnitt durch den Ringbügel g in Elxialansicht mit dem Exzenterring b und dem Anschlag e, in dem der Ringbügel g befestigt ist. Ferner zeigt die Abb. 3 die um den Ringbügel g gelegte Feder f, den Mitnehmernocken mit Bohrung d und den Mitnehmer c, die fest am Stellring a angebracht sind und die Aussparung h im Exzenterring b, in der der Mitnehmer c sich bewegt.The invention is illustrated in Figures 1, 2 and 3 by way of example. -It shows Fig. I the side view with the eccentric shaft w, the adjusting ring a firmly connected to it with driver c, which engages in the recess h in the eccentric ring b. Furthermore, Fig. I shows the spring f, the ring bracket g and the stop e on the eccentric ring; Fig.2 shows the axial view with the driver cam with bore d, which is attached to the adjusting ring 'a, as well as the driver c, which lies in the recess h of the eccentric ring b. Furthermore, Fig. 2 shows the spring f, the ring bracket g and the stop e on the eccentric ring; Fig. 3 shows the section through the ring bracket g in axial view with the eccentric ring b and the stop e, in which the ring bracket g is attached. Furthermore, Fig. 3 shows the spring f placed around the ring bracket g, the driver cam with bore d and the driver c, which are firmly attached to the adjusting ring a and the recess h in the eccentric ring b, in which the driver c moves.

PATENTANSPRÜCHE: i. Anordnung eines Exzenters auf einer Welle, dadurch gekennzeichnet, daß der Exzenter lose auf der Exzenterwelle (w) sitzt und z. B. durch einen Mitnehmer (c) und eine Feder (f) derart mit dieser kraftschlüssig verbunden ist, daß bei einer Rückdrehung der Exzenterwelle (w) deren Drehung durch die Feder (f) aufgenommen wird und der Exzenter selbst in seiner alten Lage verbleibt. PATENT CLAIMS: i. Arrangement of an eccentric on a shaft, characterized in that the eccentric sits loosely on the eccentric shaft (w) and z. B. by a driver (c) and a spring (f) is positively connected to this so that when the eccentric shaft (w) is rotated back, its rotation is absorbed by the spring (f) and the eccentric itself remains in its old position. 2. Anordnung eines Exzenters auf einer Welle nach Anspruch i, dadurch gekennzeichnet, daß die Aussparung (h) im Exzenterring (b) durch ihre Größe die Rückdrehung begrenzt und eine zu weite schädliche Rückdrehung verhindert.2. Arrangement of an eccentric on a shaft according to claim i, characterized in that that the recess (h) in the eccentric ring (b) limits the reverse rotation due to its size and prevents excessive reverse rotation.
