Description

Erschütterungsdämpfung an Kompassen. Um die kreisenden Schwingungen der Kompaßrose zu verhindern, die durch die von den Maschinen und dem Seegang verursachten Erschütterungen des Schiffskörpers verursacht werden, hat man den Kompaß an Federn aufgehängt, die zwischen dem am Kompaßstand befindlichen Ring und dem Kardan- oder Baancering des Kompasses angeordnet sind. Oder man hat den Kompaßkessel mittels mehrerer Gummistrippen an einem von dem Banlancering getragenen Ring aufgehängt. Die erstere Aufhängung nimmt unvorteilhaft viel Raum im Kompaßstand in Anspruch. Die Aufhängung des Kompaßkessels mittels Gummistrippen ist infolge der Eigenschaft des Gummis, bald zu erhärten, unzweckmäßig.Vibration dampening on compasses. About the circling vibrations the compass rose caused by the engines and the swell If the hull is caused by vibrations, the compass is attached to springs suspended between the ring on the compass stand and the cardan or Baancering of the compass are arranged. Or you have the compass boiler by means of several rubber strips suspended from a ring carried by the banana ring. The former suspension disadvantageously takes up a lot of space in the compass stand. The suspension of the compass boiler by means of rubber strips is due to the property of the rubber, soon to harden, inexpedient.

Die Erschütterungsdämpfung bei Kompassen gemäß der vorliegenden Erfindung ist frei von diesen Nachteilen. Sie besteht darin, daß die beiden Zapfenlagerungen des Kompaßkessels im. Balancering nicht in starrer Verbindung mit dem Kompaßkessel sind, sondern durch ausgespannte Federn mit dem Kompaßkessel allseitig nachgiebig verbunden sind, derart, daß sich letzterer sowohl in der Ringebene als auch in senkrecht zu letzterer stehender Richtung und sich somit auch in den aus beiden Richtungen resultierenden Richtungen in dem Balancering nachgiebig bewegen kann.The shock absorption in compasses according to the present invention is free from these disadvantages. It consists in the fact that the two journal bearings of the compass pocket in the. The balancing ring is not rigidly connected to the compass pocket but are flexible on all sides thanks to the extended springs with the compass pocket are connected in such a way that the latter is both in the plane of the ring and in perpendicular to the latter standing direction and thus also in the from both directions resulting directions in the balancing ring can move resiliently.

Auf der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt; sie zeigt den Kompaßkessel ohne Kompaßrose und Deckglas.In the drawing, the invention is shown in one embodiment; it shows the compass pocket without the compass rose and cover glass.

Die bisher am Kompaßkessel a festsitzenden beiden Tragezapfen b sind an dem Balancering c an dessen Innenseite mittels der Schraubenmuttern d befestigt. Auf den Tragezapfen b ist achsial unverschiebbar je eine Lagerhülse e mittels Kugeln leicht drehbar. Diesen Lagerhülsen e ist mittels der abwärts gerichteten Schraubenfedern f der Kompaßkessel nachgiebig aufgehängt. Um das Kippen des letzteren zu verhindern, sind an die Lagerhülsen e je zwei schwächere Schraubenfedern g oberhalb des Zapfens b angeschlossen, die nach entgegengesetzten Richtungen führend mit ihrem anderen Ende mit dem Kompaßkessel a verbunden sind, und zwar so, daß in den Federn f und g, g eine gewisse Spannung herrscht. Die so gespannt gehaltenen Lagerhülsen e, nämlich die Lagerungen des Kompaßkessels in dem Balancering sind somit derart federnd am Kompaßkessel angeordnet, daß letzterer nach allen Richtungen federnd- nachgiebig im Balancering hängt. Die Federn f nehmen insbesondere die senkrechten und die Federn g die seitlichen Erschütterungen auf.The two supporting pegs b, which were previously stuck on the compass vessel a, are fastened to the inner side of the balance ring c by means of the screw nuts d. One bearing sleeve e is axially immovable and can be easily rotated by means of balls on the support pin b. The compass vessel is flexibly suspended from these bearing sleeves e by means of the downwardly directed helical springs f. In order to prevent the latter from tipping over, two weaker helical springs g are connected to each of the bearing sleeves e above the pin b, which are connected to the compass vessel a in opposite directions with their other end leading in such a way that in the springs f and g, g there is a certain tension. The bearing sleeves e held so tensioned, namely the bearings of the compass chamber in the balancing ring, are thus resiliently arranged on the compass chamber in such a way that the latter hangs resiliently in the balancing ring in all directions. The springs f absorb the vertical vibrations and the springs g absorb the lateral vibrations.

In weniger zweckmäßiger Weise kann auch der Drehzapfen b durch die Federn f und g mit dem Kompaßkessel verbunden sein, wobei dann die Lagerhülsen e an dem Balancering c festsitzen.In a less expedient manner, the pivot b can also be connected to the compass vessel by the springs f and g, in which case the bearing sleeves e are firmly attached to the balance ring c.
