Description
Es ist bekannt, daß 01, welches mit feinen Eisenspänen durchsetzt ist, unter dem Einfluß magnetischer Kräfte seine Viskosität in weiten Grenzen verändert, je nach der Menge der dem C51 zugesetzten Eisenspäne.It is known that oil, which is interspersed with fine iron filings, changes its viscosity within wide limits under the influence of magnetic forces, depending on the amount of iron filings added to the C51.
Es hat bisher an Schwingungsdämpfern gefehlt, bei denen man in einfachen und in weiten Grenzen wirksamer Weise die Dämpfungseigenschaften beeinflussen konnte. Durch den Gegenstand der Neuerung wird diese Möglichkeit erreicht. Das Gehäuse des Dämpfers wird so ausgebildet, daß in ihm Elektromagnete eingebaut werden, die je nach dem gewünschten Dämpfungseffekt ihre magnetischen Kräfte ausüben. Je nach dem Anteil der Mischung, in der die Eisenspäne dem 01 zugesetzt werden, kann die Dämpfung fast bis zur Starrheit des Dämpfers gesteigert werden.Up to now there has been a lack of vibration dampers in which the damping properties could be influenced in a simple and effective manner within wide limits. This possibility is achieved through the subject of the innovation. The housing of the damper is designed in such a way that electromagnets are installed in it, which, depending on the desired damping effect, exert their magnetic forces. Depending on the proportion of the mixture in which the iron filings are added to the 01, the attenuation can be increased almost to the rigidity of the damper.
In der Zeichnung ist ein Vorschlag zur Anordnung des Schwingungsdämpfers gebracht: Das isolierte Gehäuse i hat einen Oberteil 2, an dem der Fuß der Maschine 3 durch Schrauben 4 befestigt ist. Unter dem Raum für die Federung 5 befindet sich ein weiterer Raum 6, in dem der Dampferkolben 7, dessen Schaft 8 in der oberen Wand gleitet, sich mit Spiel bewegt. Der Raum 6 ist mit Dämpfungsflüssigkeit gefüllt, die mit Eisenspänen durchsetzt ist. In den Raum ragen die Pole 9 und io des Magnets hinein. Selbstverständlich kann die Anordnung des Dämpfungsraumes auch z. B. neben dem Raum 5 der Federung oder auch mit diesem kombiniert erfolgen.The drawing shows a proposal for the arrangement of the vibration damper: The insulated housing i has an upper part 2 to which the base of the machine 3 is fastened by screws 4. Under the space for the suspension 5 there is another space 6 in which the steam piston 7, the shaft 8 of which slides in the upper wall, moves with play. The space 6 is filled with damping fluid which is interspersed with iron filings. Poles 9 and 10 of the magnet protrude into the space. Of course, the arrangement of the damping chamber can also, for. B. next to the space 5 of the suspension or combined with this.
