Description
Überlastungskupplung, bei der der gegenseitige Schlupf die Ausrückvorrichtung
betätigt
In der zeichnung werden zwei Attsführungsheisltiele der l?rfittdittig gezeigt.In the drawing, two guidelines are used shown.
ebb. t stellt einett -;cltttitt durch die Kul>ltlung mit Zahnscheibe, :11t1>. 2 eine Einzelheit dazu und Abh. 3 die gleiche Kupplung, jedoch mit Gewindescheibe, dar.ebb. t represents a -; cltttitt through the cultivation with toothed washer, : 11t1>. 2 a detail and Dep. 3 the same coupling, but with a threaded washer, represent.
All dein treibenden Kupplungsteil 1 ist die Ventilstange = drehbar angeordnet. Sie ist an ihrem 1#:nde als I)rehschieher 3 ausgebildet und trägt am anderen Ende ein Bedienungshandrad 4. Weiter sitzt auf der Ventilstange 2, fest mit ihr verbunden, die Zahnsegmentscheibe 5 (vgl. auch Abb. 2). All of your driving coupling part 1 is the valve rod = rotatably arranged. It is designed on its 1 #: nde as I) deer 3 and carries an operating handwheel 4 at the other end. The toothed segment disk 5 is also located on the valve rod 2, firmly connected to it (see also Fig. 2).
I:in als Zahnrad ausgebildeter Teil der getriebenen Kupplungshälfte, im Ausführungsbeispiel die Lamelle 7, kämmt mit den Zähnen der ZahnsegInentscheibe ;.I: in part of the driven coupling half designed as a gear, In the exemplary embodiment, the lamella 7 meshes with the teeth of the toothed segment disc ;.
Wird durch Überlastung eine Winkelverdrehung zwischen den beiden Kupplungshälften hervorgerufen, so wird die Zahnsegmentscheibe 5 durch die Zahnlamelle 7 ebenfalls um einen bestimmten Winkel, der sich aus dein Zahnverhältnis beider Scheiken ergibt, gedreht. Diese Drehung bewirkt gleichzeitig über die Ventilstange 2 ein Öffnen des Ventils mit dem Drehschieber 3. Der auf dem in dem treibenden Kupplungsteil angeordneten Schließkolben 9 lastende Druck wird dadurch beseitigt und die Reibungshaftung der Kupplungslamellen aufgehoben, die Kupplung also abgeschaltet.Overload causes an angular twist between the two coupling halves caused, the toothed segment disk 5 is also caused by the toothed lamella 7 at a certain angle, which results from your tooth ratio of the two sheiks, turned. This rotation simultaneously causes the valve rod 2 to open Valve with the rotary slide 3. The one arranged on the in the driving coupling part Closing piston 9 onerous pressure is eliminated and the frictional adhesion of the Clutch plates canceled, so the clutch is switched off.
Zur Vermeidung von Betriebsstörungen durch sellisttiitiges Weiterdrehen der Zahnsegment-#:clieilte 5, beispielsweise infolge der Vibration, ist in derselben eine Ausnehmung io (vgl. Abb. 2) und ini Kupplungsgehäuse ein Bolzen ii vorgesehen, der nach erfolgter Abschaltung der Kupplung durch den Druck der Feder 6 zum Eingriff kommt und ein Hinrasten der Zalinsegnientsclieilte 5 ermöglicht.To avoid operational disruptions through continued turning on the shop floor the tooth segment - #: clieilte 5, for example due to the vibration, is in the same a recess io (see Fig. 2) and ini coupling housing a bolt ii is provided, after the clutch has been switched off by the pressure of the spring 6 to engage comes and enables the Zalinsegnientsclieilte 5 to snap into place.
Die Vorrichtung kann durch Herausziehen und Zurückdrehen des Handrades d wieder in Bereitschaftsstellung gebracht werden, wobei die Möglichkeit besteht, mit Hilfe von Sichtmarken od. dgl. den zum =auslösen der Vorrichtung gewiinschten Verdrehungswinkel voreinzustellen.The device can be opened by pulling out and turning back the handwheel d be brought back into readiness position, whereby there is the possibility of with the help of sight marks or the like, the ones desired to trigger the device Pre-set angle of rotation.
Die Ausbildung nach Abb. 3 entspricht in ihrem ,grundsätzlichen Aufbau der vorstehend beschriebenen. hm Gegensatz zu ihr ist jedoch das Treibelement des getriebenen Kupplungsteils als Ge-\vindescheibe 15 ausgebildet; sie bewirkt deshalb hei der überlastungsverdrehting der beiden Kupplungshälften eine axiale Verschiebung des Mitnahmestückes i- in Dichtung des Handrades. Durch die Verschiebung des Mitnahmestückes 14 wird der Dreliscliielter 3 über die Ventilstange 2 auf j seine Öffnungsstellung hin bewegt, wobei die Abinessungen so getroffen werdest, daß das -Mitnahmestück 1d, nachdem es aus der Gewindescheibe 15 lierausbewegt worden ist, finit Hilfe der Feder 6 den Drehschieber 3 schlagartig ganz in Üffnungsstellung zieht und das Abschalten der Kupplung bewirkt. In eine Nut 13 der Ventilstange 2 greift der gefederte Bolzen 12 ein und verhindert deren Drehung.The training according to Fig. 3 corresponds in its basic structure the one described above. In contrast to it, however, is the driving force behind the driven coupling part designed as a threaded disk 15; it therefore works the overload twisting of the two coupling halves results in an axial displacement of the driving piece i- in the seal of the handwheel. By moving the take-away piece 14, the valve holder 3 is moved to its open position via the valve rod 2 moved towards, whereby the dimensions are made so that the -throwing piece 1d, after it has been moved out of the threaded disk 15, finitely with the aid of the Spring 6 suddenly pulls the rotary valve 3 completely into the open position and switches off the clutch causes. The spring-loaded bolt engages in a groove 13 in the valve rod 2 12 and prevents it from rotating.
Die neue Vorrichtung kann durch entsprechende Auswahl der Zalinzalilvei-li*,iltnisse lizw. der Gewindegänge den jeweiligen Betriebserfordernissen angepaßt werden.The new device can be used by appropriate selection of the Zalinzalilvei-li *, iltnisse lizw. the threads can be adapted to the respective operating requirements.
Die Erfindung ist nicht an ciie beiden Ausführungsbeispiele gebunden; es liegt in der Hand des Konstrukteurs, den l:rfinditngsgedanken in der Weise auszuwerten, daß die Vorrichtung auch auf Sicherheitskupplungen anderer, z. 13. elektromagnetischer Bauart Anwendung finden kann.The invention is not restricted to either of the two exemplary embodiments; It is in the hands of the designer to evaluate the idea in such a way that the device can also be used on other safety couplings, e.g. 13. electromagnetic design can be used.
