Description
Vulcan-Getriebe Bei Vulcangetrieben für leicht gebaute Schiffe spielt meistens die Frage des Schwungmoments der primären Kupplungshälfte sowie der elastischen Länge der Welle, welche die hydraulische Kupplung mit der Antriebsmaschine verbindet,. eine wichtige Rolle. Sowohl das Schwungmoment als auch die elastische Länge der Welle müssen möglichst niedrig gehalten werden, damit die Eigenschwingungszahl des Primärsystems eine möglichst hohe wird, so daß gefährliche kritische Drehzahlgebiete oberhalb der Betriebsdrehzahlen zu liegen kommen.Vulcan gearbox Vulcan gearboxes play a role in lightly built ships mostly the question of the moment of inertia of the primary coupling half as well as the elastic one Length of the shaft that connects the hydraulic coupling to the prime mover. an important role. Both the moment of inertia and the elastic length of the Shaft must be kept as low as possible so that the natural frequency of the Primary system as high as possible, so that dangerous critical speed ranges come to lie above the operating speed.
Man hat bereits die Lösung des Problem, eine kurze elastische Länge für die Verbindung zwischen Kupplung und Maschine zu erhalten, durch Anwendung einer Trommelhelle zu finden gesucht. Dabei hat sich indessen herausgestellt, daß Trommelwellen von einem Durchmesser, welcher ausreicht, um die elastische Länge genügend herabzudrücken, selbst wieder ein so großes Schwungmoment besitzen, daß der Vorteil, welcher an Verkürzung der elastischen Länge erzielt wird, durch das vergrößerte Schwungmoment der Trommelwelle wieder aufgehoben wird. Man kommt also bei dieser Konstruktion bald an eine unüberwindliche Grenze.One already has the solution to the problem, a short elastic length for the connection between the coupling and the machine by using a Wanted to find drum light. It has been found, however, that drum shafts of a diameter which is sufficient to depress the elastic length sufficiently, themselves have such a large moment of inertia that the advantage of which Shortening of the elastic length is achieved by the increased moment of inertia the drum shaft is lifted again. So you get with this construction soon to an insurmountable limit.
Anders liegen die Verhältnisse, wenn gemäß der Erfindung eine Trommelwelle aus Leichtmetall gewählt wird. In diesem Falle wächst das Schwungmoment rnitZunahme des Durchmessers der Trommelwelle viel weniger an, so daß also eine-starke Verringerung der -elastischen Länge erzielt werden kann, ohne das Schwungmoment in gleichem :Maße anwachsen zu lassen. Dieser Erfolg wird noch erhöht, wenn zugleich auch der Primärläufer der Kupplung aus Leichtmetall besteht.The situation is different if, according to the invention, a drum shaft made of light metal. In this case, the moment of inertia increases as it increases the diameter of the drum shaft is much less, so that there is a strong reduction the elastic length can be achieved without the moment of inertia in the same: dimensions to grow. This success is increased even more, albeit at the same time as the primary runner the coupling is made of light metal.
Die Zeichnung zeigt schematisch ein Ausführungsbeispiel. Der Primärläufer A der hydraulischen Kupplung besteht aus Leichtrnetall und ist beispielsweise mit einer mehr oder weniger langen Trommelwelle B aus einem Stück gegossen. An die Trommelwelle ist die Welle D der Antriebsmaschine C, z. l'). Brennkraftmaschine, angeflanscht.The drawing shows schematically an embodiment. The primary runner A of the hydraulic clutch is made of light metal and is, for example, with a more or less long drum shaft B cast in one piece. To the drum shaft is the shaft D of the prime mover C, e.g. l '). Internal combustion engine, flanged.
Es empfiehlt sich, die Trommelwelle an ihrem gelagerten Teil mit einer reibungsfesten Auflage, z. B. einer Stahlbandage E, zu versehen.It is recommended that the drum shaft be fitted with a friction-resistant support, e.g. B. a steel bandage E to be provided.
Mit F ist eine Schiffsschottwand bezeichnet, durch die die Trommelwelle hindurchgeführt ist.F is a ship bulkhead through which the drum shaft is passed through.
