Description
Mehrzylindrige Kolbenmaschinen, insbesondere Verbreimungsmaschinen mit hohen Drehzahlen, wie sie im Schiffsbetriebe angewandt werden, besitzen den Übelstand, daß bei gewissen Drehzahlen Verdrehungsschwingungen der Kurbelwelle auftreten, die zu unruhigem Gang und zu Brüchen Veranlassung geben. Die Erfindung bezweckt, diesen Übelstand zu beseitigen, und erreicht diesen Zweck im wesentlichen dadurch, daß in einem mit der Kurbelwelle fest verbundenen, mit Flüssigkeit angefüllten Gehäuse eine gegen Federdruck frei drehbare Masse angeordnet ist, deren unterschiedliche Bewegungen gegenüber dem Gehäuse durch eine regelbare Drosselvorrichtung abgebremst werden können.Multi-cylinder piston machines, in particular crimping machines with high speeds, as they are used in ship operations, have the disadvantage that with certain Rotational speeds Torsional vibrations of the crankshaft occur, which give rise to uneven gear and breaks. The invention aims to remedy this drawback and substantially achieves that aim in that in a firmly connected to the crankshaft, filled with liquid Housing a freely rotatable mass against spring pressure is arranged, the different Movements relative to the housing can be braked by an adjustable throttle device.
In der Zeichnung ist der Gegenstand der Erfindung beispielsweise in einer Ausführungsform veranschaulicht, und zwar zeigen In the drawing, the subject matter of the invention is illustrated, for example, in one embodiment, namely show
Abb. ι einen senkrechten Querschnitt undFig. Ι a vertical cross section and
Abb. 2 einen senkrechten Längsschnitt durch die neue Vorrichtung zum Dämpfen der. Verdrehungsschwingtingen.Fig. 2 is a vertical longitudinal section through the new device for damping the. Torsional oscillation.
. Auf der Kurbelwelle H ist ein Schwungring Ä frei drehbar gelagert, der das Bestreben hat, während des Betriebes sich gleichförmig. On the crankshaft H a flywheel Ä is freely rotatably mounted, which tends to be uniform during operation
zu drehen. Der Schwungring ist von einem Gehäuse B umschlossen, das starr mit der Kurbelwelle verbunden und durch einen Dekkel B1 dicht verschlossen ist. Der Schwung-' ring A und das Gehäuse B; besitzen Klauen a1 und b1, die nach Art der Klauenkupplungen ineinandergreifen. Zwischen den einzelnen Klauen ist jedoch so viel Spiel vorhanden, daß Zwischenräume C entstehen, in denen schraubenförmige Druckfedern D eingebaut sind, die sich einerseits, gegen eine Klaue α1 des Schwungringes, andererseits gegen eine Klaue b1 des Gehäuses stützen. Die Hohlräume, die zwischen dem Gehäuse B und den/ Schwungringe A vorhanden sind, sind mit einer Flüssigkeit, zweckmäßig mit Öl, vollkommen ausgefüllt. Je zwei zu beiden Seiten einer Klaue b1 gelegene Räume C sind durch eine Leitung c1 miteinander verbunden; in "diese ist ein einstellbares Drosselventil E eingeschaltet, das je nach seiner Einstellung den Übertritt der Flüssigkeit von einem Räume C zum anderen mehr oder weniger behindert. Die Zuführung der Flüssigkeit zu den Hohlräumen des Gehäuses B erfolgt dauernd von der Druckleitung / einer ■— auf der Zeichnung nicht dargestellten —■ Pumpe aus durch Bohrungen h1, h" der Kurbelwelle H sowie durch seitliche Ausnehmungen α2 und Bohrungen an, α4, α5 des Schwungringes A. Damit die in die Hohlräume eingeführte Flüssigkeit nicht rückwärts strömen und auf die Pumpe zurückwirken kann, sind in die Austrittskanäle a5 Rückschlagventile F eingebaut. An dem Gehäuse sind außerdem Austrittsöffnungen G von geringem, regelbarem Querschnitt angebracht, aus denen dauernd ein kleiner Teil der Flüssigkeit austreten kann. to turn. The flywheel is enclosed by a housing B , which is rigidly connected to the crankshaft and is tightly closed by a cover B 1. The flywheel A and the housing B; have claws a 1 and b 1 , which intermesh in the manner of claw clutches. However, there is so much play between the individual claws that spaces C arise in which helical compression springs D are installed, which are supported on the one hand against a claw α 1 of the flywheel and on the other hand against a claw b 1 of the housing. The cavities that are present between the housing B and the flywheels A are completely filled with a liquid, expediently with oil. Two spaces C located on either side of a claw b 1 are connected to one another by a line c 1; . in "this an adjustable throttle valve E is turned on, which hinders the passage of the fluid from a space C for other more or less, depending on its setting, the supply of the liquid to the cavities of the housing B is carried out continuously from the pressure line / a ■ - on the drawing not shown - ■ pump through holes h 1 , h "of the crankshaft H and through lateral recesses α 2 and holes a n , α 4 , α 5 of the flywheel A. So that the liquid introduced into the cavities does not flow backwards and up the pump can react, 5 non-return valves F are built into the outlet channels. In addition, outlet openings G of small, controllable cross-section are attached to the housing, from which a small part of the liquid can continuously escape.
Beilm Auftreten von Verdrehungsschwingungen der Kurbelwelle H muß das Gehäuse B, weil es starr mit der Welle verbunden ist, diese Schwingungen mitmachen; der Schwungring A dagegen ist bestrebt, seine gleichförmige Umfangsgeschwindigkeit beizubehalten. Er wird jedoch hierin um so mehr gehindert, je mehr das Drosselventil E. die in den Hohlräumen C verdrängte Flüssigkeit am Übertreten von einem Räume zum anderen hindert. Wird nämlich das Drosselventil E ganz geschlossen und ist alle Luft aus der Vorrichtung ausgetrieben, so muß, da die Flüssigkeit nicht zusammendrückbar ist, der' Schwungring A die Verdrehungsschwingungen des Gehäuses und des ganzen Wellen-.When torsional vibrations of the crankshaft H occur , the housing B, because it is rigidly connected to the shaft, must take part in these vibrations; the flywheel A, however, strives to maintain its uniform peripheral speed. However, the more the throttle valve E. prevents the liquid displaced in the cavities C from passing from one space to the other, the more it is hindered here. If the throttle valve E is completely closed and all air is expelled from the device, then, since the liquid is not compressible, the flywheel A must absorb the torsional vibrations of the housing and the entire shaft.
systems voll mitmachen; der lose Schwungring ist dann also gleichsam mit der Welle gekuppelt. Ist dagegen das Drosselventil £ ganz geöffnet, so kann der Schwungring1 seine gleichförmige Geschwindigkeit annähernd beibehalten, und es wird beim Auftreten von Verdrehungsschwingungen jeweils eine unterschiedliche Bewegung zwischen dem losen Schwungringe und dem starr mit der Welle .verbundenen-Gehäuse eintreten,, wobei jeweils eine gewisse Menge der Flüssigkeit von einem Hohlräume -in den anderen verdrängt wird. Der- Größe der unterschiedlichen Bewegung des losen Schwungringes gegenüber dem festen Gehäuse sind ili diesem Falle, da eine Drosselung der Flüssigkeit nicht stattfindet, nur durch die eingebauten Federn Grenzen gesetzt. Die Federn haben überdies den Zweck, den losen Schwungring jedesmal wieder in seine Mittellage zurückzuführen. Durch entsprechende Einstellung des Dro-sselventils E ist es möglich, bei einer bestimmten Größe der auftretenden größten Verdrehungsschwingungen diesen einen solchen Widerstand entgegenzusetzen, daß die Schwingung gedämpft wird, bevor sie sich ■ vollkommen ausbilden kann. Hierdurch ist aber der Zweck, die Beanspruchung des schwingenden Systems herabzusetzen, erreicht.systems fully participate; the loose flywheel is then, as it were, coupled to the shaft. If, on the other hand, the throttle valve £ is fully open, the flywheel 1 can approximately maintain its uniform speed, and when torsional vibrations occur, a different movement will occur between the loose flywheel and the housing rigidly connected to the shaft a certain amount of liquid is displaced from one cavity into the other. The size of the different movements of the loose flywheel in relation to the fixed housing are in this case only limited by the built-in springs, since there is no throttling of the liquid. The springs also have the purpose of returning the loose flywheel to its central position each time. By setting the throttle valve E accordingly, it is possible, at a certain size, to oppose the greatest torsional vibrations that occur with such a resistance that the vibration is damped before it can develop completely. However, this achieves the purpose of reducing the stress on the oscillating system.
Die Vorrichtung zeichnet sich durch ihre einfache Bauweise, ihre leichte Einstellbarkeit und die Leichtigkeit, mit der sie selbst an älteren Maschinen noch nachträglich angebracht werden kann, besonders aus.The device is characterized by its simple construction, its easy adjustability and the ease with which it can be retrofitted even on older machines can be especially made.
