Description

In der Patentschrift 834 477 sind federnde Ringe beschrieben, die aus gewelltem Stahlblech bestehen und zur Nabenbefestigung von Maschinenteilen dienen. Wie in der Patentschrift 834 477 ausgeführt ist, können durch geeignete Ausbildung der Ringe beliebige und genau bestimmbare. Haftkräfte zwischen den verbundenen Teilen erreicht werden. Versuche mit diesen Ringen haben gezeigt, daß auch bei Überschreiten der Haftkräfte, z. B. beim Verdrehen der Maschinenteile gegeneinander, die federnden Eigenschaften der Ringe erhalten bleiben und damit auch die Haftkraft. Diese Eigenschaft der Ringe wird erfindungsgemäß zur Ausbildung einer Überlastungskupplung benutzt, die gegenüber bekannten Überlastungskupplungen den Vorteil hat, daß sie geringe Abmessungen aufweist, einfach und billig ist und im Grenzfall aus den federnden Ringen und den verbundenen Maschinenteilen selbst bestehen kann. Einzelheiten der Erfindung gehen aus dem nachstehend an Hand der Zeichnung beschriebenen Ausführungsbeispiel hervor.In the patent 834 477 resilient rings are described which consist of corrugated sheet steel and are used to attach machine parts to the hubs. As stated in the patent 834 477, can by suitable training the rings are arbitrary and precisely determinable. Adhesive forces between the connected parts can be achieved. Tests with these rings have shown that even when exceeded the adhesive forces, e.g. B. when rotating the machine parts against each other, the resilient Properties of the rings are retained and thus also the adhesive force. This attribute the ring is used according to the invention to form an overload clutch, which has the advantage over known overload clutches that they are low Has dimensions, is simple and cheap and in the borderline case from the resilient Rings and the connected machine parts themselves can exist. Details of the Invention go from the embodiment described below with reference to the drawing emerged.

Abb. I zeigt einen Längsschnitt durch eine Überlastungskupplung, Abb. 2 einen Schnitt nach Linie II-II der Abb. I, Abb. 3 eine andere Befestigung der Kupplung nach Abb. I.Fig. I shows a longitudinal section through an overload clutch, Fig. 2 a section along line II-II of Fig. I, Fig. 3 another attachment of the Coupling according to Fig. I.

Eine Nabe I und eine Welle 2 sind durch eine Überlastungskupplung verbunden, die aus zwei Buchsen 3 und 4 besteht, die durch Keile 5 und 6 mit der Welle 2 bzw. der Nabe I verbunden sind. Die Buchse 3 weist drei flache Ringnuten 7 auf, in denen je ein federnder Ring 8 mit Vorspannung eingesetzt ist. Die Ringe sind aus gewelltem Stahlband gebogen, das glatte Randzonen 9 und Io aufweist. Die Höhe und Teilung der Wellen und die Blechstärke der Federringe, also die Federkraft der Ringe, ist entsprechend der gewünschten Haftreibung gewählt. Die Büchsen 3 und 4 sind gehärtet.A hub I and a shaft 2 are through an overload clutch connected, which consists of two sockets 3 and 4, which by wedges 5 and 6 with the Shaft 2 and the hub I are connected. The socket 3 has three flat annular grooves 7, in each of which a resilient ring 8 is used with bias. The Rings are bent from corrugated steel strip, which has smooth edge zones 9 and Io. the Height and pitch of the waves and the sheet metal thickness of the spring washers, i.e. the spring force the rings, is selected according to the desired static friction. The cans 3 and 4 are hardened.

Bei der Abwandlung nach Abb. 3 sind die Buchsen 2o und 2I mit der Nabe I und der Welle 2 nicht durch Keile, sondern ebenfalls durch federnde Ringe 22, 23, die in Nuten 24, 25 der Buchsen untergebracht sind, verbunden. Die federnden Ringe 22, 23 sind mit so hoher Vorspannung eingepreßt, daß bei Überlastung nur die Buchsen 20 und 2I aufeinandergleiten können, nicht dagegen die Teile I und 2 gegenüber den mit ihnen verbundenen Buchsen.In the modification according to Fig. 3, the sockets 2o and 2I with the Hub I and the shaft 2 not by wedges, but also by resilient rings 22, 23, which are housed in grooves 24, 25 of the sockets, connected. The resilient ones Rings 22, 23 are pressed in with such a high bias that only the Bushings 20 and 2I can slide on each other, but not parts I and 2 opposite the sockets connected to them.
