Description

Gegenstand der Erfindung ist eine Kupplung mit Zentrierkonus, welche nur für Wellen verwendet werden soll, die mit unveränderlicher Drehrichtung angetrieben werden und bei denen die angetriebene Welle durch eine Selbstsperrung an der Lockerung der Verbindung gehindert ist. Bei bekannten Kupplungen dieser Art erfolgt die Übertragung des Drehmomentes durch Schraubengewinde, bei denen das ganze Drehmoment von Gewindegängen aufgenommen werden muß. Auch werden für derartige Kupplungen vielfach Spezialgewinde, z. B. konisches Gewinde, verwendet. Besondere Schwierigkeit bereitete bisher die genaue Einhaltung der Axialität der gekuppelten Wellen.The invention relates to a coupling with a centering cone which is only used for shafts which are driven with a fixed direction of rotation and for which the driven shaft is prevented from loosening the connection by a self-locking mechanism. In known clutches of this type, the torque is transmitted through Screw threads in which the entire torque has to be absorbed by thread turns. Also for such couplings often special threads, e.g. B. conical thread used. Particular difficulty previously prepared the exact compliance with the axiality of the coupled shafts.

Hier verbessert die Erfindung dadurch, daß der Wellenzapfen der einen Welle und die entsprechende Kernbohrung in der anderen Welle mit Gewinde von solcher Steigerung versehen sind, daß beim Gang der Maschine sich die Wellen ineinanderschrauben, daß sich der Zapfen der einen Welle in die Kernbohrung der Nachbarwelle schraubt und einen zwischen Zapfen und Welle angeordneten Konus zentrierend in den Hohlkonus der Nachbarwelle zieht.Here the invention improves in that the shaft journal of a shaft and the corresponding one Core bore in the other shaft are provided with a thread of such an increase that when the machine is running, the Screw the shafts into each other so that the pin of one shaft is in the core hole of the neighboring shaft screws and a cone arranged between the pin and shaft centering in the The hollow cone of the neighboring shaft pulls.

In der Zeichnung ist der Gegenstand der Erfindung in einer Abbildung beispielsweise dargestellt. In the drawing, the object of the invention is shown in a figure, for example.

Die Welle α ist mit einem Konus b und einem Schraubenzapfen c versehen. Die Nachbarwelle d ist entsprechend mit einem Hohlkonus und einer mit Gewinde versehenen Kernbohrung ausgerüstet. The shaft α is provided with a cone b and a screw pin c. The adjacent shaft d is accordingly equipped with a hollow cone and a threaded core bore.

Wird das zu übertragende Drehmoment größer, so schraubt sich der Gewindezapfen c selbsttätig weiter in die Gewindebohrung der angetriebenen Welle d ein und verstärkt dadurch die Reibungskraft zwischen den konischen Flächen der Kupplung, die das Drehmoment zu übertragen haben.If the torque to be transmitted is greater, the threaded pin c automatically screws further into the threaded bore of the driven shaft d and thereby increases the frictional force between the conical surfaces of the coupling which have to transmit the torque.
