Description

Die Erfindung bezieht sich auf eine biegsame Wellenkupplung, die aus zwei auf den Wellen befestigten Naben mit Außenzahnkränzen und zwei mit diesen durch Innenzahnkränze treibend verbundenen und sie gehäuseartig umschließenden Flanschmuffen besteht. Bei solchen Wellenkupplungen macht die Abdichtung des Raumes, in dem die Zahnkränze arbeiten, nach außen hin Schwierigkeiten, weil die auf den Wellen befestigten Naben gegenüber den Flanschmuffcn beweglich sein müssen.The invention relates to a flexible shaft coupling, which consists of two on the Shafts attached hubs with external sprockets and two with these by internal sprockets driving connected and they housing-like enclosing flange sleeves consists. With such shaft couplings, the seal makes the space in which the ring gears work, outward difficulties, because the hubs attached to the shafts are opposite the flange sleeves must be movable.

Gemäß der Erfindung ist diese Schwierigkeit dadurch behoben worden, daß die Naben mit Kugelllächen versehen sind, die an entsprechenden Hohlkugelrlächen der Flanschmuffen anliegen, wobei die Kugelliächen der Xaben und der Flanschen vorteilhaft federnd gegeneinandergedrückt werden. Auf diese Weise ist eine einwandfreie Abdichtung geschaffen, ohne daß dadurch die Biegsamkeit der Wellenkupplung beeinträchtigt wird.According to the invention, this problem has been overcome in that the hubs are provided with spherical surfaces that are attached to corresponding The hollow spherical surfaces of the flange sleeves are in contact with the spherical surfaces of the Xaben and the flanges are advantageously pressed against each other in a resilient manner. To this Way, a perfect seal is created without compromising flexibility the shaft coupling is impaired.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Auf den inicht gezeichneten) Wellen ist je eine Nabe 1, 2 befestigt, die mit Außenzahnkränzen 3,4 versehen ist. Diese Zahnkränze greifen in jeAn exemplary embodiment of the invention is shown in the drawing. On the in not shown) shafts there is one hub 1 each, 2 attached, which is provided with external gear rings 3.4. These sprockets engage in each

einen Innenzahnkranz 5,6, die an Flanschmuffen 7, S gebildet sind, die die Naben 1, 2 gehäuseartig umschließen. Die Zähne der Außenzahnkränze 3, 4 sind so gekrümmt, dal.', die Naben i, 2 bzw. die in diesen befestigten Wellen allseitig beweglich sind. An den Naben i, 2 sind Kugelliächen 9, ι ο gebildet, die an entsprechende Hohlkugelflächen 11, 12 der Flanschmuffen anliegen. Eine zwischen den beiden Naben angeordnete Feder 13 drückt diese Kugelflächen federnd gegeneinander. an internal ring gear 5,6, which are formed on flange sleeves 7, S , which enclose the hubs 1, 2 like a housing. The teeth of the external gear rims 3, 4 are curved in such a way that the hubs i, 2 or the shafts fastened in these are movable on all sides. On the hubs i, 2 spherical surfaces 9, ι ο are formed, which bear against corresponding hollow spherical surfaces 11, 12 of the flange sleeves. A spring 13 arranged between the two hubs resiliently presses these spherical surfaces against one another.
