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.
