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.
