Description

Die Lamellen -- elektromagnetischer Lamellenkupplungen werden im allgemeinen in der Zone der Erregerspule mit Luftspalten und Durchbrüchen versehen, damit die magnetischen Kraftlinien möglichst vollständig über den Anker fließen. Die zwischen den Luftspalten verbleibenden Stege aus dem ferromagnetischen Werkstoff der Lamellen lenken aber immer noch einen großen Teil der aus der Spule austretenden Kraftlinien von diesem Wege ab, zumal die Stege schon aus mechanischen Gründen nicht zu schmal und dünn sein dürfen. Man hat deshalb schon elektromagnetische Lamellenkupplungen mit Lamellen gebaut, die an Stelle eines perforierten Kreisringes in der Zone der Erregerspule einen Ringeinsatz aus einem nichtmagnetischen Werkstöff, z. B. Bronze, besitzen, der mit der inneren und der äußeren Ringscheibe durch Niete, Klauen oder Kerbverzahnung befestigt ist. Aber auch diese Bauweise stellt keine befriedigende Lösung der Aufgabe dar, eine elektromagnetisch betätigte Lamellenkupplung mit Lamellen zu schaffen, die bei einfacher Herstellung auch betriebsicher sind und den KraftlinienfluB über den Anker nicht stören. Denn abgesehen. dävön, da B die Herstellung der erwähnten Lamellen mehrere Arbeitsgänge erfordert, ist der Halt der drei Ringscheiben auch bei sorgfältigster Ausführung ihrer Verbindung nicht fest genug, um bei starker Beanspruchung und Erwärmung ein Verziehen der Lamellen und als Folge davon eine Lockenurig :oder sogar ein Lösen ihrer Verbindung mit Sicherheit auszuschließen.The multi-disc electromagnetic multi-disc clutches are used in general Provided with air gaps and openings in the zone of the excitation coil so that the magnetic lines of force flow as completely as possible over the armature. The between the air gaps remaining webs made of the ferromagnetic material of the lamellae but still direct a large part of the lines of force emerging from the coil from this path, especially since the webs are not too narrow for mechanical reasons and be allowed to be thin. That is why one already has electromagnetic multi-plate clutches built with slats that replace a perforated circular ring in the zone of the Excitation coil a ring insert made of a non-magnetic Werkstöff, z. B. bronze, own that with the inner and outer ring washer by rivets, claws or Serration is attached. But this type of construction is not a satisfactory one either The solution to the problem is an electromagnetically operated multi-disc clutch with discs to create, which are also operationally reliable with simple production and the flow of force lines do not bother about the anchor. Because apart from that. dävön, since B the production of the mentioned Lamellae requires several work steps, the hold of the three ring discs is also if their connection is carried out most carefully, it will not be firm enough to cope with strong Stress and heating lead to warping of the lamellas and, as a result, a Curly: or even to rule out a loosening of their connection with certainty.

Die vorliegende Erfindung hat eine elektromagnetisch betätigte Lamell_enkupplungzum Gegenstand, deren ferromagnetische Lamellen aus Sintereisen bestehen und durch einen nichtmagnetisierbaren Ring aus kompaktem, oder gesintertem Metall, Kunststoff od. dgl. unterteilt sind, wobei die genannten . Teile durch Pressen, Sintern und/oder Verbacken miteinander zu einem Stück verbunden sind. Wenn der Zwischenring: aus Metall besteht, wird er mit dem Außen- und dem Innenring von Sintereisen in einem oder mehreren Arbeitsgängen zu einem Stück verpreBt und dann gesintert. Besteht er dagegen aus Kunstharz oder einem ähnlichen Werkstoff, so werden zunächst der Innen- und der Außenring von Sintereisen für sich verpreBt und gesintert und darauf mit dem Zwischenring in an sich bekannter Weise verbacken. Durch dieses Herstellungsverfahren erzielt man eine vorzügliche Verbindung der drei Ringscheiben miteinander, die auch den stärksten Beanspruchungen gewachsen ist. In der Abb. i ist eine solche neue Lamelle, in der Abb.2 eine mit diesen Lamellen ausgerüstete elektromagnetische Lamellenkupplung im Schnitt dargestellt. Die Innen-und Außenringe i und 2 der Lamelle bestehen aus Sintereisen, der in der Zone der Erregerspule 3 befindliche Zwischenring 4 aus Sinterbronze. Wie bereits durch umfangreiche Betriebsversuche festgestellt wurde, genügen die neuen Lamellen allen Anforderungen, die man an solche Kupplungselemente stellen kann. Sie sind einfach und billig herzustellen und besitzen eine gute mechanische Stabilität und einen günstigen Reibungsbeiwert. Die unmagnetischen Zwischenringe lenken die magnetischen Kraftlinien nicht von ihrem Weg über die Ankerscheibe ab, außerdem sind sie auch noch als Reibflächen wirksam.The present invention has an electromagnetically operated multi-disc clutch Object whose ferromagnetic lamellas are made of sintered iron and through a non-magnetizable ring made of compact or sintered metal, plastic or similar Like. Are divided, said. Parts by pressing, sintering and / or Baked together to form one piece. If the intermediate ring: off Is made of metal, it is made in one with the outer and inner rings of sintered iron or several work steps pressed into one piece and then sintered. Consists If, on the other hand, it is made of synthetic resin or a similar material, the Inner and outer ring of sintered iron pressed and sintered separately and on top baked with the intermediate ring in a known manner. Through this manufacturing process one achieves an excellent connection of the three ring disks with each other, that too can cope with the toughest demands. In Fig. I there is such a new one Lamella, in Fig. 2 an electromagnetic multi-disk clutch equipped with these lamellae shown in section. The inner and outer rings i and 2 of the lamella consist of Sintered iron, the intermediate ring 4 made of sintered bronze in the zone of the excitation coil 3. As has already been determined by extensive operational tests, they are sufficient new lamellas meet all the requirements that such coupling elements have to meet can. They are easy and cheap to manufacture and have good mechanical properties Stability and a favorable coefficient of friction. The non-magnetic intermediate rings do not divert the magnetic lines of force from their path over the armature disk, in addition, they are also effective as friction surfaces.
