Die Erfindung bezieht sich auf eine Wellenkupplung, bei der die Wellenenden nach Art von Nut und Feder keilförmig ineinandergreifen. Solche Wellenkupplungen sind brauchbar, wenn die Welle stetig in ein und derselben Richtung rotiert, wobei praktisch kein Verschleiß auftritt.The invention relates to a shaft coupling in which the shaft ends in the manner of groove and Spring interlocking in a wedge shape. Such shaft couplings are useful when the shaft is steadily in rotates in the same direction, with practically no wear occurring.

Wenn mit derartigen Kupplungen versehene Wellen jedoch durch ein nach Größe und/oder Richtung wechselndes Drehmoment belastet werden, was beispielsweise bei Waschmaschinen der Fall ist, nützen sich die Kupplungsteile rasch ab. Infolge des durch die Abnützung entstandenen Spiels treten dann stoßartige Beanspruchungen und Geräusche auf.However, if shafts provided with such couplings are affected by size and / or direction alternating torque loads, which is the case, for example, in washing machines, are useful the coupling parts quickly come off. As a result of the play created by the wear and tear, jerks then occur Stresses and noises.

Der Erfindung liegt demgemäß die Aufgabe zugrunde, eine Wellenkupplung obiger Gattung zu schaffen, bei der Spiel durch Abnützung selbsttätig ausgeschaltet wird.The invention is accordingly based on the object of providing a shaft coupling of the above type create in which the game is automatically switched off through wear and tear.

Zur Lösung dieser Aufgabe ist eine bügeiförmige Blattfeder vorgesehen, die hinter an beiden Wellenenden vorgesehene Bunde greift und so die beiden Wellen, die nach Art von Nut und Feder keilförmig ineinandergreifen, zusammenpreßt.To solve this problem, a bow-shaped leaf spring is provided behind at both shaft ends provided collars engages and so the two shafts, which are wedge-shaped in the manner of tongue and groove interlock, press together.

Durch diese Ausbildung wird zugleich eine gewisse Elastizität der Kupplung erreicht, auf Grund deren kleine Fluchtfehler der Wellenlager unschädlich bleiben. Eine Abnutzung findet an den konischen Teilen zwar statt, da jedoch die Enden der Wellen elastisch gegeneinandergepreßt werden, kann sich ein Spiel nicht bilden. Zur Ausschaltung des Spiels zwischen den Kupplungshälften sind nämlich zwei Maßnahmen notwendig. Nut und Feder müssen mit ineinandergreifenden Keilfiächen ausgebildet sein; weiterhin muß eine diese Keilflächen axial gegeinanderdrükkende Feder vorgesehen sein.Through this training, a certain elasticity of the coupling is achieved at the same time, due to which small misalignments of the shaft bearings remain harmless. Wear takes place on the conical parts although instead, since the ends of the shafts are elastically pressed against each other, a game can develop not make up. To eliminate the play between the coupling halves there are two measures necessary. Tongue and groove must be designed with interlocking wedge surfaces; Farther a spring which axially presses against one another must be provided for these wedge surfaces.

Bei einer bekannten Kupplung der genannten Art sind zwar die Wellenenden nach Art von Nut und Feder keilförmig ineinandergreifend gestaltet, es fehlt aber das zweite zur Lösung der gestellten Aufgabe notwendige Mittel, eine die Keilflächen axial zusammendrückende Feder. Bei einer anderen Kupplung ist schon eine in axialer Richtung wirkende federnde Klammer vorgeschlagen worden. Dort ist jedoch eine Nut- und Federverbindung vorgesehen, die nicht keilförmig ausgebildet ist. Die Lösung der gestellten Aufgabe und die genannten Vorteile werden aber erst durch die erfindungsgemäße gemeinsame Anwendung der beiden Ausgestaltungsmaßnahmen erreicht.In a known coupling of the type mentioned, the shaft ends are in the manner of groove and The spring is designed to interlock in a wedge shape, but the second to solve the problem is missing necessary means, a spring compressing the wedge surfaces axially. With a different clutch a resilient clamp acting in the axial direction has already been proposed. However, there is one Tongue and groove connection is provided, which is not wedge-shaped. The solution to the task at hand and the advantages mentioned are only achieved through the joint application according to the invention of the two design measures achieved.

Ferner kann bei der Kupplung nach der Erfindung eine Verbindung der Wellen besonders schnell und einfach gelöst werden.Furthermore, in the coupling according to the invention, a connection of the shafts can be particularly fast and easily solved.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.

Fig. 1 zeigt eine Seitenansicht der Wellenkupplung undFig. 1 shows a side view of the shaft coupling and

F i g. 2 ist ein Querschnitt nach der Linie II-II in Fig. 1.F i g. 2 is a cross section along the line II-II in FIG. 1.

Die Enden der Wellen sind mit 1 und 2 bezeichnet, die Nut- und Federverbindung mit 3, die Bunde 4 werden von einer Blattfeder 5 hintergriffen.The ends of the shafts are denoted by 1 and 2, the tongue and groove connection with 3, the collars 4 are engaged from behind by a leaf spring 5.

Die Form der Blattfeder wird so gewählt, daß ihre offenen Enden leicht nach außen gebogen sind, um ein leichtes und sicheres Aufsetzen der Feder sicherzustellen. The shape of the leaf spring is chosen so that its open ends are bent slightly outwards to to ensure easy and safe placement of the spring.

Damit der Hauptzweck der Kupplung immer erfüllt wird, nämlich die Vermeidung jeglichen durch Abnützung entstehenden Spieles, muß darauf geachtet werden, daß axial ein Abstand zwischen den Bunden 4, desgleichen zwischen den Stirnflächen an Nut und Feder aufrechterhalten bleibt, d. h. die Wellenenden dürfen an keiner Stelle, mit Ausnahme der keilförmigen Flächen an Nut und Feder, aneinanderstoßen. So that the main purpose of the clutch is always fulfilled, namely the avoidance of any through Wear resulting play, care must be taken that there is an axial distance between the collars 4, is also maintained between the end faces at the tongue and groove, d. H. the shaft ends may not butt against each other at any point, with the exception of the wedge-shaped surfaces on the tongue and groove.
