Description

Schraubenfeder-Reibungskupplung. Die Erfindung betrifft eine Rejbungslcupplung, deren Schraubenfeder die an dem einen Federende angreifende Kraft infolge der einstellbaren Federdehnung, teilweise oder ganz auf die zu kuppelnde Welle überträgt. Längenänderungen von Schraubenfedern in solchen Kupplungen sind zwar schon bekannt, dienten bisher aber nur zur Ein- und Ausschaltung.Coil spring friction clutch. The invention relates to a friction clutch, whose coil spring acts on one end of the spring as a result of the adjustable force Spring expansion, partially or completely transferred to the shaft to be coupled. Changes in length of coil springs in such clutches are already known and have been used so far but only for switching on and off.

Die Feder kann durch Verschiebung nach der einen oder anderen Seite in Klaueneingriff mit einem der beiden Triebräder eines Wendegetriebes gebracht werden und den Vor- oder Rückwärtsgang der zu kuppelnden Welle vermitteln.The spring can be shifted to one side or the other brought into claw engagement with one of the two drive wheels of a reversing gear and convey the forward or reverse gear of the shaft to be coupled.

Die Federstreckung oder Krafteinstellung kann ebenso wie die Federverschiebung oder Umschaltung auf Vor- oder Rück-,v ärtsgang während des Betriebes vorgenommen werden.The spring extension or force adjustment can be done as well as the spring displacement or switch to forward, reverse or forward gear during operation will.

Auf der Zeichnung ist die Schraubenfeder-Reibungskupplung in Fig. i und z dargestellt. Die Schraubenfeder a ist aus einem vollen Zylinder geschnitten und läuft an ihren Enden zu Ringen aus, die mit Klauenansätzen versehen sind. Diese Ansätze bilden j ederseits mit entsprechenden Ausbildungen der Triebräder b je eine Klauenkupplung. Die Feder cz ist in der Länge so bemessen, daß sie nur auf einer Seite in Klaueneingriff stehen kann, der beim Antrieb die Federwindungen auf die Mitlehmertrommel c spannt und da eine Umfangskraft durch den Reibungswiderstand zwischen Feder und Trommel erzeugt.In the drawing, the coil spring friction clutch in Fig. i and z shown. The coil spring a is cut from a full cylinder and ends at their ends in rings that are provided with claws. These Approaches form one each with corresponding designs of the drive wheels b Claw coupling. The length of the spring cz is so dimensioned that it is only on one Side can be in claw engagement, which when driving the spring coils on the Clamping drum c tensions and there is a circumferential force due to the frictional resistance generated between spring and drum.

Die Umfangskraft wird erhöht, indem die Scherenhebel e durch das Handrad mit Zinks-und Rechtsgewinde d gegen die beiden Kugellager f drücken und die Feder strecken.The circumferential force is increased by moving the scissor lever e through the handwheel with zinc and right-hand threads d press against the two ball bearings f and the spring stretch.

Zur Umschaltung der Reibungskupplung auf Vor- oder Rückwärtsgang dient das Handrad g, das durch die Gewindespindel h, die Scherenhebel e und die Kugellager f die Verschiebung der Feder a. auf der Trommel c und den bestimmten Klaueneingriff bewirkt.The hand wheel is used to switch the friction clutch to forward or reverse gear g, h by the threaded spindle, the scissor levers e and the ball bearings f the displacement of the spring a. on the drum c and causes the specific claw engagement.
