Description

Es sind elektromagnetisch betätigte Reibungskupplungen und -bremsen bekannt, bei denen das Bremsen oder Einrücken durch Aneinanderhaften im elektromagnetischen Feld befindlicher Seheiben bewirkt wird. Es wunde bereits vorgeschlagen; diese Scheiben in der Gestalt konzentrischer Ringe aus ferromagnetischem Werkstoff auf nicht magnetischen Trägerscheiben herzustellen. Während des Betriebes entstehen aber Schwierigkeiten, weil die Ringe sich unter der Einwirkung der Wärme dehnen, so daß die Scheiben nicht eben bleiben. Entweder ergibt sich daraus ein Festklemmen, oder die zu kuppelnden Scheiben haften schlecht aneinander.They are electromagnetically operated friction clutches and brakes known in which the braking or engagement by sticking together in the electromagnetic Field located Seheiben is effected. It wound already proposed; these discs in the form of concentric rings made of ferromagnetic material on non-magnetic Manufacture carrier disks. However, difficulties arise during operation because the rings expand under the action of heat, so the disks do not stay even. Either this results in a clamping, or the one to be coupled Slices adhere poorly to one another.

Den Gegenstand der Erfindung bildet eine Ausbildung der Scheiben, die es den Ringen gestattet, sich während des Eingriffs frei zu dehn en, damit die Scheiben eben bleiben.The subject of the invention is a formation of the discs, which allows the rings to stretch freely during the procedure so that the Slices stay flat.

Die neuen Scheiben bestehen aus je einer Nabe mit sternförmig verlaufenden Armen, auf denen die Ringe zentrisch von. daran 'befestigten Bügeln festgehalten werden, die auf den Armen gleiten können.The new discs each consist of a hub with a star shape Arms on which the rings are centered by. attached to the bracket that can slide on the arms.

Wenn der Durchmesser der Ringe sich infolge der Wärmedehnung verändert, ergibt sich aus dieser Anordnung keine Formveränderung der Scheiben, so daß die zusammengesetzten Scheiben sich stets einwandfrei berühren und dadurch eine richtige Übertragung der Kräfte bewirken.If the diameter of the rings changes due to thermal expansion, results from this arrangement no change in shape of the discs, so that the composite panes always touch each other perfectly and thus a correct one Effect the transfer of forces.

Es wird nachfolgend an Hand der Zeichnung ein Ausführungsbeispiel des Erfindungsgegenstandes beschrieben.An exemplary embodiment is shown below with reference to the drawing of the subject matter of the invention described.

Abb. i ist eine Ansicht auf die Rückseite einer Scheibe; Abh. 2 ist eine schaubildliche Darstellung; Abb. 3 1i st ein axialer'Sc:hni tt ,durch eine Kuppl ung ; Abb. 4 ist ein Schnitt in größerem 'Maßstab nach der Linie IV-IV der Abb. 3.Fig. I is a view of the rear of a disc; Dep. 2 is a diagrammatic representation; Fig. 3 1i st an axial'Sc: hni tt, through a Coupling; Fig. 4 is a section on a larger scale on the line IV-IV of Fig. 3.

Jeder Ringträger besteht aus einer Nabe i aus nicht magnetischem Werkstoff mit einer beliebigen Anzahl sternförmig verlaufender Arme 2. Die ferromagnetischen Ringe 3 liegen flach auf den Armen und werden konzentrisch von Bügeln gehalten, die an den Ringen durch Schrauben, Schweißstellen od. dgl. befestigt sind und auf den Armen 2 gleiten können (Abb. 4).Each ring carrier consists of a hub i made of non-magnetic material with any number of star-shaped arms 2. The ferromagnetic ones Rings 3 lie flat on the arms and are held concentrically by brackets, which are attached to the rings by screws, welds or the like and on the arms 2 can slide (Fig. 4).

Abb. 3 zeigt als Anwendungsbeispiel eine Kupplung mit zwei Scheiben i und 5, die jeweils auf der treibenden und der getriebenen Welle 6 oder io befestigt sind. Auf den Armen 2 und 7 dieser Scheiben sind imit Hilfe der Bügel 4 die Ringe 3 befestigt, die sich dabei im -.NTagnetfel,d der Spule 8 des Elektromagneten 9 befinden. Durch diese Anordnung wird eine einwandfreie Berührung der stets in einer Ebene verbleibenden Ringe gewährleistet, auch wenn sie durch Reibung stark erwärmt werden.Fig. 3 shows a coupling with two disks as an application example i and 5, which are mounted on the driving and driven shaft 6 or io, respectively are. On the arms 2 and 7 of these disks are the rings 4 with the help of the bracket 3 attached, which is in the -.NTagnetfel, d of the coil 8 of the electromagnet 9 are located. This arrangement ensures a perfect touch of the always in a The rings remain level, even if they are strongly heated by friction will.
