Description
Elektromagnetische Reibungskupplung. Gegenstand vorliegender Erfindung ist eire elektromagnetische Reibungskupplung mit drehendem Magnetsystem. Sie unterschei det sich von allen bekannten Systemen durch ihre kleine Baulänge, ihre Einfachheit und die dadurch gewährleistete grösste Betriebs sicherheit.
Das Wesen der Erfindung besteht darin, dass die Ausrückvorrichtung der Kupplung im Schleifringträger angeordnet ist, wodurch die erwähnte Vereinfachung der Bauart und die beträchtliche Verkleinerung der Baulänge der Kupplung erreicht wird.
In der beiliegenden Zeichnung zeigen die Fig. 1--3 Ausführungsformen des Erfindungs gegenstandes an Scheibenkupplungen. In dessen sind diese Ausführungsformen ohne weiteres auch an Einfach- oder Doppelkonus kupplungen anwendbar. Die Ausrückvorrich- tung kann zum Beispiel aus Federn bestehen.
Fig. 1 zeigt eine Ausführungsform für kleine Kupplungen, bei denen die Ausrück- vorrichtung durch eine einzige Feder gebildet wird, die koachsial zur Kupplungsachse liegt. Fig. 2 und 3 zeigen Ausführungen mit mehre ren kleinen Federn, die auf einem Kreise koachsial zur Kupplungsachse angeordnet sind.
In den Figuren bezeichnet 1 den achsial beweglichen Magneten, in welchem die Er regerspule 2 eingebaut ist. Dieser Magnet ist auf dem Träger 3 gelagert, welcher auf der treibenden Welle 4 fest aufgekeilt ist. Die Übertragung des Drehmomentes zwischen dem Magneten 1 und dem Träger 3 kann durch Federkeile 5 geschehen. 6 ist ein Gewindering, welcher auf dem Magneten 1 aufgeschraubt und auf dem innern Umfang mit mehreren gleichmässig verteilten Keil nuten versehen ist. Er wird durch einen Keil 8 am Verdrehen gehindert und dient dazu, den Luftspalt 7, durch welchen die Stärke des magnetischen Zuges beeinflusst werden kann auf das richtige Mass einzustellen, was durch Lösen des Keils 8 und Verdrehen des Ringes 6 geschehen kann.
Der Keil 8 dient gleichzei tig zur Übertragung des Drehmomentes, 9 ist der Anker, welcher auf der getriebenen Welle 14 fest aufgekeilt ist, und 10 ist ein Reib- Belag zur Ermöglichung grösserer Leistungs übertragung. 11 sind die zur Stromzuführung dienenden Schleifringe, welche auf einem Schleifringträger 12 angebracht sind. 13 sind die auf Entkupplung wirkenden Stossfedern, welche in der Ausführungsart nach Fig. 3 auf Bolzen 15 wirken.
Wird von den Schleifringen 11 aus der Spule 2 ein Strom zugeführt, so entsteht ein durch eine mit Pfeilspitzen versehene punk tierte Linie dargestellter magnetischer Fluss, der in der Luftspalte 7 eine Zugkraft zwi schen Magnet 1 und Anker 9 ausübt, durch welche der Magnet 1 gegen den Anker 9 gezogen wird. Dadurch werden die Federn 13 gespannt, welche beim Unterbrechen des Er regerstromes den Magneten wieder in seine Ausgangslage pressen und den Reibkontakt zwischen Anker und Nachstellring lösen.
Electromagnetic friction clutch. The present invention relates to an electromagnetic friction clutch with a rotating magnet system. It differs from all known systems in terms of its short length, its simplicity and the highest level of operational reliability that it guarantees.
The essence of the invention is that the release device of the clutch is arranged in the slip ring carrier, whereby the aforementioned simplification of the design and the considerable reduction in the overall length of the clutch is achieved.
In the accompanying drawings, FIGS. 1-3 show embodiments of the subject matter of the invention on disk clutches. In this, these embodiments are easily applicable to single or double cone couplings. The release device can consist of springs, for example.
1 shows an embodiment for small clutches in which the release device is formed by a single spring which is coaxial to the clutch axis. Fig. 2 and 3 show versions with several Ren small springs that are arranged on a circle coaxially to the coupling axis.
In the figures, 1 denotes the axially movable magnet in which the He regerspule 2 is installed. This magnet is mounted on the carrier 3, which is firmly keyed onto the driving shaft 4. The torque can be transmitted between the magnet 1 and the carrier 3 by means of spring wedges 5. 6 is a threaded ring which is screwed onto the magnet 1 and is provided on the inner circumference with several evenly distributed keyways. It is prevented from twisting by a wedge 8 and is used to set the air gap 7, through which the strength of the magnetic pull can be influenced, to the correct level, which can be done by loosening the wedge 8 and rotating the ring 6.
The wedge 8 is used at the same time to transmit the torque, 9 is the armature, which is firmly keyed on the driven shaft 14, and 10 is a friction lining to enable greater power transmission. 11 are the slip rings which are used to supply power and which are attached to a slip ring carrier 12. 13 are the shock springs acting on the decoupling, which act on bolts 15 in the embodiment according to FIG.
If a current is supplied from the slip rings 11 from the coil 2, a magnetic flux is produced by a dotted line provided with arrowheads, which exerts a tensile force between the magnet 1 and armature 9 in the air gap 7, through which the magnet 1 counteracts the anchor 9 is pulled. As a result, the springs 13 are tensioned, which when the excitation current is interrupted press the magnet back into its starting position and release the frictional contact between the armature and the adjusting ring.
