Description
Die Kupplung der Erfindung gewährleistet eine ausgezeichnete Schmierung, die eine ständige Überwachung und Wartung dieses wichtigen Maschinenteils entbehrlich macht.The coupling of the invention ensures excellent lubrication, which do not require constant monitoring and maintenance of this important machine part power.
Um diesen Vorteil zu erzielen, weist eine ein-und ausrückbare Zahnkupplung für verhältnismäßig langsam laufende oder, häufigen Richtungswechseln unterworfene Antriebe, insbesondere für drehstromangetriebene Walzwerkshilfsantriebe, die zwischen den I,'-upplungszähnen stets einen Ölfilm erzeugen, gemäß der Erfindung eine,Ausbildung auf, bei der die Zahnlücken der äußeren Kupplungshälfte zur Aufnahme von 01 .in ihrem Grunde taschenartig erweitert und vorteilhaft miteinander verbunden sowie nach außen so abgeschlossen sind, daß Öl nicht ausfließen kann. Das hat den weiteren Vorteil, daß sich in den Zahnlücken Abrieb od. dgl. nicht absetzen und gegebenenfalls zu Zahnbrüchen führen kann. Dabei ist es zweckmäßiig, daß der Ab.-schluß der erweiterten Zahnlücken aus einem in die äußere Kupplungshälfte als besonderes Element eingesetzten Dichtungsring, z. B. aus Stahl, besteht.In order to achieve this advantage, an engageable and disengageable tooth clutch for relatively slow-running drives or drives that are subject to frequent changes of direction, in particular for three-phase auxiliary rolling mill drives that always generate an oil film between the clutch teeth, according to the invention, has a design, in which the gaps between the teeth of the outer coupling half for receiving 01 .in their bottom expanded like a pocket and advantageously connected to one another and closed off to the outside in such a way that oil cannot flow out. This has the further advantage that abrasion or the like does not settle in the tooth gaps and can possibly lead to tooth breakage. It is expedient that the conclusion of the enlarged tooth gaps from a sealing ring inserted into the outer coupling half as a special element, e.g. B. made of steel.
In der Zeichnung sind zwei als Beispiele dienende Ausführungsformen der Erfindung dargestellt. Fig. i und 2 zeigen die neue Kupplung im Längs-und Querschnitt.In the drawing are two exemplary embodiments of the invention shown. FIGS. I and 2 show the new coupling in longitudinal and cross-section.
i ist die äußere Kupplungshälfte, die auf der Getriebesente auf die Welle aufgeschrumpft wird. 2 ist der andere Kupplungsteil, der auf dem Motorzapfen sitzt.i is the outer half of the coupling, which is attached to the gear unit Shaft is shrunk on. 2 is the other coupling part, which is on the motor journal sits.
In der Kupplungshälfte i ist ein Ringraum 3 für einen Ölvorrat q. vorgesehen. Die Nuten zwischen den Lamellen 5 in der glockenförmigen Kupplungshälfte i, die zum Eingriff der Lamellen 6 der anderen Kupplungshälfte 2 dienen, sind in ihrem Grunde zu Taschen 7 erweitert, die ebenfalls zur Aufnahme von Öl dienen können.In the coupling half i there is an annular space 3 for an oil supply q. intended. The grooves between the plates 5 in the bell-shaped coupling half i, which serve to engage the disks 6 of the other coupling half 2, are shown in FIG their bottom expanded to pockets 7, which can also be used to hold oil.
Aus, konstruktivem Gründen ist zur Formung der Öltaschen ? ein Dichtungsring 8, z. B. aus- Stahl, in die Kupplungshälfte i eingesetzt, der deren Hohlraum 3 nach außen abdichtet. Die Dnchtungsfuge liegt über dem Ölspiegel.For structural reasons, is it necessary to shape the oil pockets? a sealing ring 8, e.g. B. made of steel, inserted into the coupling half i, the cavity 3 after seals on the outside. The waterproofing joint lies above the oil level.
Wie Fig. 3 zeigt, gehen die Flanken 9 der Kupplungslamellen 5 mit großer Abrundung in die Öltaschen über, die dadurch einen besonders großen Raum bilden. Die Stege io der Lamellen 5 sind besonders schwach gehalten. Dadurch haben die Öltaschen 7 größtmögliche Abmessungen, und die Lamellen selbst besitzen dadurch federnde Eigenschaften.As FIG. 3 shows, the flanks 9 of the clutch disks 5 go along with it large rounding into the oil pockets, which creates a particularly large space form. The webs io of the slats 5 are kept particularly weak. Have thereby the oil pockets 7 have the largest possible dimensions, and the slats themselves thereby resilient properties.
Das 01 4, das in den Vorratsraum 3 eingebracht ist, wird beiim Umlauf der Kupplung in die Öltaschen 7 geschleudert. Aus den oberen Taschen ergießt es sich, insbesondere sobald die Kupplung stillgesetzt oder ihre Drehrichtung geändert wird, über die Lamellen, so daß eine einwandfreie Schmierung eintritt.The 01 4 that is brought into the storage space 3 is thrown into the oil pockets 7 as the clutch rotates. It pours out of the upper pockets, especially as soon as the clutch is stopped or its direction of rotation is changed, over the lamellae, so that perfect lubrication occurs.
Da das Öl sowohl in der Ruhelage als auch beim Betrieb nicht an den Trennspalt zwä,schen den beiden Kupplungshälften i, 2 reicht und Ölspritzer durch den Dichtungsring 8 abgeschirmt werden, entsteht praktisch kein ölverlust, so daß die Kupplung keiner Wartung bedarf. Sie ist weitgehend verschleißfrei,, gestattet ein schnelles. Auswechseln ohne irgendein Werkzeug, ist billig, gut ausgewuchtet, hat nur geringes Trägheitsmoment, einen verhältnismäßig kleinen Durchmesser, läuft unter Vermittlung des Ölfilms und der federnden Lamellen sehr elastisch und bildet insofern eine Sicherung für den Motor; als ihre schmale Dichtungsfuge frühzeitig eine gefährliche Annäherung zwischen dessen Rotor und Stator erkennen läßt.Since the oil does not reach the Separation gap between the two coupling halves i, 2 is enough and oil splashes through the sealing ring 8 are shielded, there is practically no loss of oil, so that the coupling does not require any maintenance. It is largely wear-free, permitted a quick one. Replacement without any tools, is cheap, well balanced, has a low moment of inertia, a relatively small diameter, runs with the mediation of the oil film and the resilient lamellas very elastic and forms insofar a fuse for the engine; than their narrow sealing joint at an early stage reveals a dangerous approach between its rotor and stator.
