KAISERLICHES A IMPERIAL A
PATENTAMT.PATENT OFFICE.
Bei elektromagnetischen Kupplungen ist es bekannt, zwecks Ergänzung abgenutzter Reibflächen auswechselbare Polaufsätze aus einem schwer dauernd magnetisier baren Material anzuordnen. Stellt man diese Polaufsätze aus einem Material von hoher magnetischer Remanenz her, so hat man den Vorteil, daß nach dem Ausschalten des erregenden Magnetstromes die Flächen noch aufeinander magnetisch festgehalten werden.In electromagnetic clutches, it is known to supplement worn friction surfaces to arrange interchangeable pole attachments made of a hard permanent magnetizable ble material. If you make these pole attachments from a material of high magnetic remanence, you have the advantage that After switching off the exciting magnetic current, the surfaces are still magnetically on top of each other be held.
Man hat damit eine Kupplung, für die man unter Umständen bei richtiger Abmessung der Polaufsätze in normalem. Betrieb überhaupt keinen Magnetisierungsstrom benötigt.So you have a coupling for which you can, under certain circumstances, with the correct dimensions of the Pole towers in normal. Operation does not require any magnetizing current at all.
Das Ausschalten einer solchen Kupplung kann dann in bekannter Weise dadurch erfolgen, daß man einen Stromstoß in entgegengesetzter Richtung durch die Magnetbewicklung schickt, um so den remanenten Magnetismus zu beseitigen.Such a clutch can then be switched off in a known manner by that you get a current surge in the opposite direction through the magnet winding sends in order to eliminate the remanent magnetism.
Die beiliegende Zeichnung zeigt ein Ausführungsbeispiel des Erfindungsgedankens:The accompanying drawing shows an embodiment of the inventive concept:
Die beiden zu kuppelnden Wellen α und b tragen einerseits in bekannter Anordnung den Stahlgußkörper c, andererseits als Anker des Magneten den an einer Membran befestigten Ankerring d. Die Erregung des Magnetkörpers erfolgt durch die Spule e. Die miteinander in Berührung kommenden Polflächen werden wie üblich durch aufgeschraubte Vollringe oder Segmente f1 und fz, g1 und g2 gebildet, die einerseits an dem Magnetkörper und andererseits an dem Ankerring leicht auswechselbar befestigt sind.The two shafts α and b to be coupled carry on the one hand, in a known arrangement, the cast steel body c, and on the other hand, as the armature of the magnet, the armature ring d attached to a membrane. The magnet body is excited by the coil e. The pole faces that come into contact with one another are formed as usual by screwed-on full rings or segments f 1 and f z , g 1 and g 2 , which are attached to the magnet body on the one hand and to the armature ring on the other.
Unter dem Einfluß der Erregerspule werden die Polaufsätze selbst zu permanenten Magneten und bewirken so ein Festhaften aneinander, selbst wenn der Stromkreis unterbrochen ist.Under the influence of the excitation coil, the pole pieces themselves become permanent magnets and thus make them stick together even if the circuit is broken is.
