Description
Wellenkupplung. Die vorliegende Erfindung betrifft eine nachgiebige und biegsame Wellenkupplung ohne mit gegenseitiger Reibung zueinander bewegliche Teile. Die Wellenkupplung besteht gemäss der Erfindung aus zwei Kupplungs muffen mit einander zugekehrten abgesetzten Zapfen und einer auf diese geschobenen kräf tigen Schraubenfeder, die als elastisches Kupplungsglied dient. Die erforderliche feste Verbindung zwischen Schraubenfeder und Kupplungsmuffen kann durch Befestigung der Federender an den Zapfen, bezw. Muffen herbeigeführt werden, oder aber auch durch Aufziehen der Feder auf beide Muffenzapfen mittelst an diesen vorgesehenen Gewindes, das dem der Feder entspricht. Eine solche Kupplung bedingt nur ein ungefähres Aus richten der zu verbindenden Wellenzapfen.
Sie gleicht auch auftretende Erschütterungen und die damit verbundenen wechselseitigen Verschiebungen der beiden Wellenzapfen gegeneinander aus, ohne Reibungsverluste zu ergeben.
Die Abbildung stellt die Neuerung in einem Ausführungsbeispiel in Fig. 1 in Ansicht und in Fig. 2 im Längsschnitte dar.
Die Wellenkupplung besteht aus den bei den Kupplungsmuffen a, a1, die mittelst einer oder mehrerer Schrauben b bezw. b1 an den zu verbindenden Wellenzapfen festgeklemmt werden. Beide Muffen a, a1 besitzen abgesetzte Zapfen c, c1, auf welche eine zweckmässig mit dichtliegenden Windungen gewickelte Feder d geschoben ist. Um eine ausreichende Verbin dung der Feder mit den Muffen a, a1 zu er zielen, haben die Muffenzapfen c, c1 der Feder d entsprechendes Gewinde, auf das die Feder d mit ihren Enden aufgepresst ist. Nötigen falls könnte an dieser Stelle noch eine Ver lötung oder Verschweissung oder ein Auf treiben der Muffenzapfen r, c1 vorgenommen werden, um die Verbindung zu einer zuver lässigen zu gestalten.
Schliesslich könnten auch die Federenden abgebogen und durch Einführen in entsprechende Aussparungen der Muffen a, a1 oder ihrer Zapfen c, c1 die notwendige feste Verbindung mit den Muffen a. a' herbeigeführt werden. Die Kupplung 1:i1,>#t sich darin sowohl für Vor- wie Rück- wärtsgang benutzen. Die Federlänge ist eine beliebige, doch wird sie zweckmässig so gewählt, dass die Kupplung den üblichen Abweichungen sowohl im Achsenabstande, wie auch im Winkel der Achsen zueinander spie lend nachgeben kann.
Shaft coupling. The present invention relates to a compliant and flexible shaft coupling without any parts that can move with mutual friction. According to the invention, the shaft coupling consists of two coupling sleeves with mutually facing offset pins and a forceful helical spring pushed onto them, which serves as an elastic coupling member. The required fixed connection between the helical spring and coupling sleeves can, respectively, by fastening the spring end to the pin. Sockets are brought about, or by pulling the spring onto both socket pins by means of a thread provided on these, which corresponds to that of the spring. Such a coupling requires only an approximate alignment of the journal to be connected.
It also compensates for any vibrations that occur and the associated reciprocal displacements of the two shaft journals against each other without causing any friction losses.
The figure shows the innovation in an embodiment in Fig. 1 in view and in Fig. 2 in longitudinal section.
The shaft coupling consists of the coupling sleeves a, a1, which by means of one or more screws b respectively. b1 to be clamped to the shaft journal to be connected. Both sleeves a, a1 have stepped pegs c, c1, onto which a spring d, suitably wound with tight turns, is pushed. In order to achieve a sufficient connec tion of the spring with the sleeves a, a1, the sleeve pins c, c1 of the spring d have a corresponding thread onto which the spring d is pressed with its ends. If necessary, soldering or welding or driving up the socket pins r, c1 could be carried out at this point in order to make the connection reliable.
Finally, the spring ends could also be bent and, by inserting them into corresponding recesses in the sleeves a, a1 or their pins c, c1, the necessary fixed connection with the sleeves a. a 'are brought about. Clutch 1: i1,> # can be used for both forward and reverse gear. The spring length is arbitrary, but it is expediently chosen so that the coupling can give way to the usual deviations both in the axis spacing and in the angle of the axes to one another.
