Description

Flüssigkeitssträfungskupplung Die Erfindung bezweckt die Herabsetzung des Schwungmoments von Flüssigkeitsströmungskupplungen .oder Getrieben, die im Zusammenhang mit Antriebsmaschinen mit ungleichförmigem Drehmoment, z. B. Brennkraftmaschin-en, verwendet werden. Durch weitgehende Verminderung des Schwungmoments kann ermöglicht werden, daß die Betriebsdrehzahlen der Anlage unterhalb gefährlicher kritischer Drehschwingungszahlen bleiben. Als ein Mittel hierzu wird gemäß der Erfindung vorgeschlagen, die Wandstärke der Kupplungs- .oder Getriebeschaufeln zum äußeren Umfang hin stetig oder alsatzweise zu verjüngen. In erster Linie soll soll diese Maßnahme für die Schaufeln des treib reden Kupplungs- oder Getriebeteiles vorgesehen werden. Sie kann aber auch gleichzeitig auf den getriebenen Kupplungsteil angewendet werden, um das Schwungmoment der Kupplung im ganzen zu verringern. Gegebenenfalls kann die Ausführung für beide Teile zweckentsprechend verschiedenartig sein, so insbeson dere in der Hinsicht, daß die Verjüngung der Schaufelwandstärken für den treibenden Teil weitgehender ist ,als für den getriebenen Teil.Fluid restriction coupling The invention aims at the reduction of the moment of inertia of fluid flow couplings. or gearboxes that are related with prime movers with non-uniform torque, e.g. B. internal combustion engines, be used. It can be made possible by largely reducing the moment of inertia be that the operating speeds of the system below dangerous critical Torsional oscillation rates remain. As a means for this, it is proposed according to the invention, the wall thickness of the clutch or gear blades steadily towards the outer circumference or to rejuvenate as a batch. First and foremost, this measure is intended for the Shovels of the driving talk clutch or transmission part are provided. she but can also be used on the driven coupling part at the same time, to reduce the moment of inertia of the clutch as a whole. If necessary, the Design for both parts may be different according to the purpose, so in particular more in the sense that the tapering of the blade wall thicknesses for the driving Part is more extensive than for the driven part.

Die Zeichnung zeigt zwei Ausführungsbi ispie:e an Bruchteilen eines Kupplungsschaufelrades.The drawing shows two Ausführungsbi ispie: e on fractions of one Clutch impeller.

Nach Fig. i haben die Schaufeln über den größeren Teil a ihrer Länge, von der Mittelachle aus gesehen, eine gleichmäßige Wandstärke, während der nahe dem äußeren Um= fang befindliche Teil b verjüngt ist.According to Fig. I, the blades have over the greater part a of their length, seen from the Mittelachle, a uniform wall thickness, while the near the outer circumference = located part b is tapered.

Gemäß Fig. a verjüngen sich die Schaufeln c stetig von der Nahe d aus bis zum Umfangsteil e.According to FIG. A, the blades c taper steadily from near d from up to the peripheral part e.

Sind kürzere Zwischenschaufeln vorgesehen, so werden diese gleichfalls entsprechend verjüngt. Die Verjüngung kann auch dadurch herbeigeführt werden, daß die Schaufeln absatzweise abnehmende Wandstärken haben, also z. B. zwischen Nabe und Innenring f, ferner zwischen diesem und Außlenring g und endlich zwischen letzterem und Umfangsteil verschiedene, aber für jeden Längenabsatz gleichmäßige, Wandstärken besitzen, die mit jedem Absatz nach außen hin geingerwerden.If shorter intermediate blades are provided, these are also used tapered accordingly. The taper can also be brought about that the blades have intermittently decreasing wall thicknesses, so z. B. between hub and inner ring f, furthermore between this and outer ring g and finally between the latter and peripheral part different, but uniform wall thicknesses for each length step that get outwardly diminished with every paragraph.
