Abstract

The coupling is particularly intended for angle displacement devices. The radial and axial displacement of the two shafts are equalized so that circumferential play with alteration of the direction of rotation of the shafts is compensated out or at any rate reduced. The spheres are pressed by springs against the radial projections on the coupling disc. The tension on the springs is adjusted by set screws. There can be hemispherical seats into which the spheres are pressed by the springs. The screws and springs are provided in bores tangential to the radial slots accommodating the arms of the centre shaft, so that they are normal to each arm.

"Coupling, especially for angle encoders, the radial and axial "offset of two shafts, consisting of its intermediate disk with recesses and two clutch disks with Projections that engage in the recesses in the intermediate disk. "

Derartige Kupplungen, die radialen und achsialen Versatz zweier Wellen ausgleichen, sind an sich bekannt. In dem Buch "Kupplungen" von Stübner/Rüggen, Carl Hanser Verlag, München 1961 sind auf den Seiten 51 bis 53 als Beispiel die pldham-Kupplung und als ■ Weiterentwicklung die Ringspann - Ausgleichskupplung beschrieben. Beide Kupplungsaüsführungen weisen bei Drehrichtungsumkehr der Wellen ein gewisses Spiel auf, das bei einem Einsatz für hochauflösende Winkelkodierer nachteilig ist.Such couplings, the radial and axial offset of two Balancing waves are known per se. In the book "Couplings" von Stübner / Rüggen, Carl Hanser Verlag, Munich 1961 are on on pages 51 to 53 the pldham coupling as an example and as ■ Further development of the Ringspann compensating coupling described. When the direction of rotation is reversed, both clutch versions show the Waves a certain game on when used for high resolution Angle encoder is disadvantageous.

Der Erfindung liegt die Aufgabe zugrunde, bei Kupplungen, die radialen und achsialen Versatz zweier Wellen ausgleichen, das Umkehrspiel bei Änderung der Drehrichtung der Wellen zu beseitigen. The invention is based on the problem of couplings that compensate for the radial and axial misalignment of two shafts Eliminate backlash when changing the direction of rotation of the shafts.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß Kugeln durch Federn, angeordnet in der Zwischenscheibe, gegen die Vorsprünge der Kupplungsscheiben gepreßt werden.This object is achieved according to the invention in that balls by springs, arranged in the intermediate disk, are pressed against the projections of the clutch disks.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß im Betrieb ein Auftreten des Umkehrspiels verhindert wird.The advantages achieved by the invention are in particular that the occurrence of backlash is prevented during operation will.

In Weiterbildung der Erfindung wird eine Vorspannung der Federn durch Schrauben eingestellt, wodurch vorteilhafterweise die Kupplung verschieden großen Drehmomenten angepaßt wird.In a further development of the invention, a bias of the springs is set by screws, which advantageously Coupling is adapted to different torques.

In einer weiteren Ausgestaltung der Erfindung werden die Kugeln durch die Federn gegen kegelförmige Sitze gepreßt.In a further embodiment of the invention, the balls are pressed against conical seats by the springs.

Der dadurch erzielte Vorteil besteht darin, daß die Kupplung zerlegt werden kann, ohne daß die Kugeln herausfallen können.The advantage achieved in this way is that the clutch is disassembled without the balls falling out.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen:An embodiment of the invention is shown in the drawing and is described in more detail below. Show it:

In each of four bores 9 of the intermediate disk 3 there are arranged a ball 1, each of which is pressed by a spring 2 against a projection V and 4 ·· 'of the clutch disks 5 1 and 5 ″. Each ball 1 can be preloaded to a predetermined value by a screw 6. When the coupling is dismantled, conical seats 7 prevent the balls from falling out.
