Description
Bei den meisten elastischen Kupplungen dienen als elastische Kupplungsglieder radial ader tangential angeordnete Blatt- oder Schraubenfedern, die durch die zu übertragenden Kräfte auf Biegung, Druck oder Zug beansprucht werden. Infolge dieser Beanspruchung muß für die elastischen Glieder verhältnismäßig viel Baustoff aufgewendet werden, wodurch die Kupplung groß, schwerMost elastic couplings serve as elastic coupling members radially or tangentially arranged leaf or helical springs, which are to be transmitted by the Forces on bending, compression or tension are stressed. As a result of this stress a relatively large amount of building material must be used for the elastic members, making the coupling large and heavy

Diese Nachteile können durch Verwendung von auf Verdrehung beanspruchten elastischen Kupplungsgliedern vermieden werden, da bei dieser Beanspruchung zur elastischen Aufnahme der Kräfte ein wesentlich geringerer Aufwand an Werkstoff genügt, so daß die Kupplung kleiner, leichter und billiger hergestellt werden kann.These disadvantages can be claimed by using on rotation elastic coupling members can be avoided, since with this stress for the elastic absorption of the forces an essential less expenditure on material is sufficient, so that the coupling can be made smaller, lighter and cheaper.
Die Verwendung elastischer, auf Verdrehung beanspruchter Kupplungsglieder ist an sich bekannt. Dabei sind aber die Kupplungsglieder in der Achsrichtung der zu kuppelnden Teile angeordnet, wodurch eine große Länge des Kupplungsgliedes bedingt ist, so daß auch diese Kupplungen die eingangs erwähnten Nachteile haben.The use of elastic coupling members that are subjected to torsion stress is known per se. However, the coupling links are in the axial direction of the coupling to be coupled Parts arranged, whereby a great length of the coupling member is required, so that these couplings are also those mentioned at the beginning Have disadvantages.
Bekannt sind ferner Kupplungen, bei denen die Kupplungsglieder schräg zur Achsrichtung liegen und durch ihre radial stehenden abgekröpften Enden mit den beiden Kupplungsteilen verbunden sind. Hierbei sind die Kupplungsglieder im wesentlichen auf Biegung beansprucht. Die außerdem auftretende Verdrehungsbeanspruchung ist in ihrer Größe abhängig von der Schräglage der Kupplungsglieder zur Achse. Je mehr sich diese Lage der radialen nähert, desto geringer wird die Beanspruchung auf Verdrehung, während diese ihr Höchstmaß bei axialer Lage der Kupplungsglieder erreicht, bei der diese Kupplung ebenso wie bei der vorher erwähnten bekannten Bauart eine große Baulänge erfordert.Also known are clutches in which the coupling members are inclined to the axial direction and by their radially offset cranked ends with the two coupling parts are connected. Here, the coupling members are essentially subjected to bending. The also occurring The size of the torsional stress depends on the inclination of the coupling links to the axis. The more this situation approaches the radial, the less the stress on torsion becomes while this reaches its maximum with the axial position of the coupling members, in which this Coupling as well as in the aforementioned known type has a large overall length requires.
Gemäß der Erfindung wird eine geringe Baulänge der Kupplung bei reiner Verdrehungsbeanspruchung der Kupplungsglieder . dadurch ermöglicht, daß die Kupplungsglieder ■ radial angeordnet sind und ihre Verdrehung durch Kurbeln bewirkt wird.According to the invention, a short overall length of the coupling is achieved with pure torsional stress the coupling links. thereby made possible that the coupling members ■ are arranged radially and their rotation is effected by cranking.
Eine beispielsweise Ausführungsform der Erfindung ist in der Zeichnung in Fig. 1 und 2" dargestellt. Dabei ist als elastisches Kupplungsglied ein diametral angeordneter Stab ο verwendet, an dessen beiden, in dem einen Kupplungsteil b drehbar gelagerten Enden der andere Kupplungsteil c nach Art eines Kurbeltriebes derart angreift, daß der Stab durch die zu übertragenden Kräfte elastisch verdreht wird. Die am Stabe a sitzenden Kurbelarime d greifen mit ihren balligen Enden in je einen Stein e, der in dem Kupplungsteil c radial und axial verschiebbar gelagert ist.An example embodiment of the invention is shown in the drawing in Fig. 1 and 2 ". A diametrically arranged rod ο is used as the elastic coupling member, at the two ends of which are rotatably mounted in one coupling part b the other coupling part c in the manner of a crank drive engages in such a way that the rod is elastically twisted by the forces to be transmitted. The crank arms d seated on the rod a grip with their spherical ends into a stone e, which is mounted in the coupling part c so as to be radially and axially displaceable.
An Stelle eines derartigen Stabes können auch mehrere angeordnet sein, wie beispielsweise für zwei und drei Stäbe in den Fig. 3 und 4 dargestellt. Diese Stäbe werden vorteilhaft so angeordnet, daß die Verdrehungslinien der einzelnen Stäbe in einer Ebene liegen.Instead of such a rod, several can also be arranged, such as, for example for two and three rods shown in Figs. These bars become beneficial arranged so that the twist lines of the individual rods lie in one plane.
