Description

Kupplung für parallel versetzte Wellen Die Erfindung bezieht sich auf eine reibungsarme und stoßdämpfende Kupplung für die gleichmäßige Übertragung einer Drehbewegung von einem Körper auf einen zweiten Körper, dessen Drehachse gegenüber der Drehachse des ersten Körpers um einengleichbleibenden Betrag parallel versetzt ist.Coupling for parallel offset shafts The invention relates to on a low-friction and shock-absorbing clutch for smooth transmission a rotational movement from one body to a second body, whose axis of rotation is opposite offset parallel to the axis of rotation of the first body by a constant amount is.

Es sind bereits Kupplungen für solche Wellen bekannt, bei denen die Enden der beiden Wellen je -eine Kupplungsscheibe tragen und diese Scheiben durch zylindrische Kupplungszapfen gekuppelt sind, welche in kreisrunde Aussparungen der Kupplungsscheiben eingreifen und bei der Drehung der Wellen auf dem Innenumfang dieser Aussparungen abrollen. Bei einer Ausführungsform dieser bekannten Kupplungen ist ein Verkanten der Kupplungszapfen möglich: bei einer zweiten ist der Zusammenbau umständlich. Bei beiden ist die Kupplung nicht elastisch nachgiebig. Um diese Nachteile zu vermeiden, erfolgt die Kupplung erfindungsgemäß durch elastisch etwas nachgiebige ILupplungsringe, von denen je einer über je zwei einander zugeordnete Kupplungszapfen gelegt ist, so daß die Kupplungszapfen beim Umlauf der Wellen auf den Innenflächen der Kupplungsringe abrollen. Bei Belastungsstößen wirken diese Kuppelringe schwingungsdämpfend, da sie die Stöße durch nachgiebige Verformung federnd abfangen. Da die Flächen, in denen die Kupplungszapfen sitzen, im Gegensatz zu den bereits bekannten Ausführungen keinerlei Ausnehmungen zu enthalten brauchen, eignet sich diese Kupplung auch für Drehkolbenmaschinen mit gegeneinander versetzten Drehachsen. Ein weiterer Vorteil dieser Bauart ist der besonders einfache Zusammenbau.There are already known couplings for such shafts in which the Each end of the two shafts - wear a clutch disc and these discs through cylindrical coupling pins are coupled, which are in circular recesses of the Clutch disks engage and rotate the shafts on the inner circumference unroll these recesses. In one embodiment of these known couplings It is possible to tilt the coupling pins: with a second one the assembly is possible laborious. In both cases, the coupling is not elastically flexible. To these disadvantages to avoid, the coupling is carried out according to the invention by somewhat resiliently resilient I coupling rings, one of which has two coupling pins that are assigned to one another is placed so that the coupling pin when rotating the shafts on the inner surfaces unroll the coupling rings. These coupling rings have a vibration-damping effect in the event of load impacts, because they absorb the impacts resiliently through resilient deformation. Since the areas in which the coupling pins sit, in contrast to the already known designs need not contain any recesses, this coupling is also suitable for Rotary piston machines with mutually offset axes of rotation. Another advantage this type of construction is particularly easy to assemble.

Die Wirkungsweise der Kupplung wird an Hand der Bilder r und z kurz erläutert. Die beiden Bilder zeigen eine beispielsweise Aus-Führung mit sechs Kuppelringen in Längs-und Querschnitt. Bauliche Einzelheiten sind dabei fortgelassen. In dem Ständer r sind die beiden Wellenenden 2 drehbar gelagert. Auf diesen sitzt je eine runde Scheibe 3 aufgekeilt. Am Rande dieser Scheiben 3 sind in gleichem Abstand von ihrer Drehachse sechs Kupplungszapfen .l gleichmäßig verteilt angeordnet. Um je zwei zugeordnete Kupplungszapfen 4. der Scheiben 3 ist ein gemeinsamer Kuppelring 5 gelegt, dessen lnnendurchmesser so bemessen ist, daß er die beidei4 Kupplungszapfen 4. mit geringem Spiel oder mit leichter Vorspannung umschließt. Wird eine der beiden Scheiben 3 durch ihn # Welle 2 iri Drehung versetzt, so wird ein Teil der Kuppelringe 5 auf Zug beansprucht und zieht an den Kupplungszapfen q. die andere Scheibe mit, so daß sich diese gleichfalls um ihre Achse drehen muß. Die Kuppelringe 5 rollen dabei mit ihrer Innenfläche auf den Kupplungszapfen :l ab, ohne daß eine gleitende Reibung entsteht. Beide Scheiben 3 drehen sich mit gleicher Winkelgeschwindigkeit um ihre Achsen.The mode of operation of the clutch is briefly explained with reference to Figures r and z. The two pictures show an example of an execution with six coupling rings in longitudinal and cross-section. Structural details are omitted. The two shaft ends 2 are rotatably mounted in the stator r. A round disc 3 is wedged onto each of these. On the edge of these disks 3, six coupling pins .l are arranged evenly distributed at the same distance from their axis of rotation. A common coupling ring 5 is placed around two assigned coupling pins 4. of the disks 3, the inner diameter of which is dimensioned so that it encloses the two coupling pins 4. with little play or with a slight bias. If one of the two disks 3 is rotated by it # shaft 2, part of the coupling rings 5 is subjected to tension and pulls on the coupling pin q. the other disk with it, so that it must also rotate around its axis. The dome rings 5 roll here with its inner surface on the coupling pin: l from without sliding friction. Both disks 3 rotate around their axes at the same angular speed.

Durch geeignete Wahl der Breite und des Außendurchmessers der Kuppelringe 5 ist es möglich, die Kupplung beliebig nachgiebig zu gestalten. Dadurch kann in vielen Fällen ein sonst erforderlicher Schwingungsdämpfer in Fortfall. kommen. Ferner kann die Herstellungsgenauigkeit bei dieser Ausführung etwas geringer sein als bei einer vollkommen starren Kupplung, da durch die Nachgiebigkeit der Kuppelringe 5 stets die Gewähr gegeben ist, daß alle Kupplungszapfen 4 zum Tragen kommen. Die Kupplungszapfen .l können bei dieser Ausführung auch bei geringen Achsabständen ziemlich kräftig gehalten werden, da ihr Durchmesser nahezu so grob wich der Achsabstand sein kann.By suitable choice of the width and the outer diameter of the coupling rings 5 it is possible to make the coupling as flexible as required. This allows in in many cases an otherwise required vibration damper is no longer needed. come. Further the manufacturing accuracy of this version may be slightly lower than that of a completely rigid coupling, because the flexibility of the coupling rings 5 there is always a guarantee that all coupling pins 4 come into play. the Coupling pin .l can also be used with this version with small center distances be held fairly strong, since their diameter gave way to the center distance almost as roughly can be.
