Description

Der exzentrisch ausgebohrte Zylinder I wird angetrieben und umfaßt die zur Drehachse konzentrisch gelagerte Schlitzwelle 2. Es entsteht also in dem Zylinder I ein sichelförmiger Hohlraum 6, der um die Schlitzwelle kreisen kann, Dieser Hohlraum 6 ist durch einen auf der Schlitzwelle angegebrachten Ansatz abgeschlossen und durch eine Lamellendichtung od. dgl. abgedichtet. In der Schlitzwelle 2 sind zwei Führungen 4 und ein geteilter Schieber 3 geführt. Die beiden Führungen 4 haben an beiden Seiten breite Flüssigkeitsdurchlässe 7. Der Schieber 3 kann z. B. durch Öldruck im Raum 5 aüseinandergedrückt werden, so daß er beide Flüssigkeitsdurchlässe 7 schließt und den sichelförmigen Hohlraum 6 in zwei Räume teilt. Der Hohlraum 6 ist mit Flüssigkeit gefüllt.The eccentrically bored cylinder I is driven and encompassed the slotted shaft 2, which is mounted concentrically to the axis of rotation Cylinder I a crescent-shaped cavity 6 that can revolve around the slotted shaft, This cavity 6 is closed by an attachment on the slotted shaft and sealed by a lamellar seal or the like. In the slot shaft 2 are two guides 4 and a split slide 3 out. The two guides have 4 on both sides wide liquid passages 7. The slide 3 can, for. B. by Oil pressure in space 5 are pressed apart so that it has both liquid passages 7 closes and divides the crescent-shaped cavity 6 into two rooms. The cavity 6 is filled with liquid.

Bei geöffnetem Schieber 3 kann die Flüssigkeit von dem einen immer kleiner werdenden in den anderen immer größer werdenden Raum hinüberströmen. Wird der Schieber geschlossen, so wird die Strömung unterbunden; die Flüssigkeit preßt sich in den kleiner werdenden Teil des Hohlraumes 6 zusammen und wirkt als Kraft auf den Schieber 3. Die Kraft wird auf die Schlitzwelle übertragen, die diese an die anzutreibende Maschine weitergibt.When the slide 3 is open, the liquid from one of them can always smaller and smaller flow over into the other, increasingly larger space. Will if the valve is closed, the flow is stopped; the liquid presses into the decreasing part of the cavity 6 and acts as a force on the slide 3. The force is transmitted to the slotted shaft, which it is connected to the machine to be driven passes on.

Die Vorteile des konstruierten Maschinenelementes bieten sich gegenüber den anderen Flüssigkeitskupplungen in einer wesentlich vereinfachten und verbilligten Herstellungsweise, gegenüber den hydraulisch betätigten mechanischen Kupplungen in einem weichen, elastischen Anziehen und wesentlich geringerem Reibungsverschleiß.The advantages of the constructed machine element offer one another the other fluid couplings in a much simplified and cheaper Manufacturing method, compared to the hydraulically operated mechanical clutches in a soft, elastic donning and significantly less frictional wear.

PATENTANSPRUCH: Vorzugsweise durch Flüssigkeitsdruck betätigte hydrostatische Wellenkupplung, gekennzeichnet durch einen zur Kupplungsachse parallel versetzten zylindrischen Hohlraum der einen Kupplungshälfte, in den über seine ganze Länge ein nach außen abgedichteter längs geschlitzter zylindrischer Ansatz der anderen Kupplungshälfte, dessen Achse mit der Kupplungsachse zusammenfällt, hineinragt, und durch zwei in dem Längsschlitz des zylindrischen Ansatzes gleitende Abschlußstücke (3), die vorzugsweise durch Druckflüssigkeit, die mit einer etwa zentrischen Bohrung dem Längsschlitz zugeführt werden kann, gegen die Wand ,des exzentrischen Hohlraumes dichtend angedrückt werden können. Angezogene Druckschriften: Deutsche Patentschriften Nr. 513 440, 549 955.Claim: hydrostatic shaft coupling, preferably actuated by fluid pressure, characterized by a cylindrical cavity of one coupling half offset parallel to the coupling axis, into which protrudes over its entire length an outwardly sealed, longitudinally slotted cylindrical extension of the other coupling half, the axis of which coincides with the coupling axis, and by two end pieces (3) sliding in the longitudinal slot of the cylindrical extension, which can be pressed sealingly against the wall of the eccentric cavity, preferably by hydraulic fluid which can be supplied to the longitudinal slot with an approximately central bore.
