Description

Elektromagnet mit BämpfungsvorrichtungElectromagnet with damping device

Die Neuerung betrifft einen Elektromagneten, z.B. einen Gleichstrommagneten mit einer Dämpfungsvorrichtung und dient der Steuerung hydraulischer Geräte. Zur Vermeidung der Klebekraft und zur Geräuschdämpfung des längsbeweglichen Ankers beim Aufschlag gegen den Kern, sind die Polflächen solcher Magnete mit unmagnetischen Auflagen versehen. Diese Auflagen, die bevorzugt aus Kunststoffoder Messingscheiben bestehen, werden auch durch mechanische Mittel zur Beeinflussung der Aufschlagsgeschwindigkeit ergänzt.The innovation relates to an electromagnet, e.g. a DC magnet with a damping device and is used to control hydraulic devices. To avoid the adhesive force and to dampen the noise of the longitudinally movable The anchor when it hits the core are the pole faces of such magnets with non-magnetic supports Mistake. These supports, which are preferably made of plastic or brass discs, are also replaced by mechanical ones Means for influencing the impact speed added.

So ist es bekannt, Federn oder Reibungselemente im Magnetsystem zu verwenden, die den starken Aufschlag des Ankers gegen die Polflächen des Kerns verhindern.So it is known to have springs or friction elements in the magnet system which prevent the armature from striking the pole faces of the core.

Bei der Neuerung wird das Kleben der Polflächen und der Aufschlag des längsbeweglichen.Ankers gegen den Kern durch einen elastischen Dämpfungsring, der als O-Ring ausgebildet ist, vermieden. Der Dämpfungsring ist vorteillaft unter Vorspannung in einer Rille am Übergang des zu einem Kegel ausgebildeten Ankerteils eingebettet und gewährleistet somit den zum Lösen der Polflächen erforderlichen Luftspalt zwischen Anker und Kern.The innovation is the gluing of the pole faces and the Impact of the longitudinally movable anchor against the core by an elastic damping ring, which acts as an O-ring is formed, avoided. The damping ring is advantageously under tension in a groove at the transition of the armature part, which is designed to form a cone, and thus ensures the required for loosening the pole faces Air gap between armature and core.

In der Zeichnung ist ein Ausführungsbeispiel dargestellt. Die Figur zeigt einen Elektromagneten entsprechend der Neuerung, teilweise im Schnitt, mit eingebettetem Dämpfungsring. An exemplary embodiment is shown in the drawing. The figure shows an electromagnet according to FIG Innovation, partly in cut, with embedded damping ring.

Mit 1 ist das zur Aufnahme und Führung der festen und beweglichen Teile als Hohlzylinder ausgebildete Führungsrohr bezeichnet. Im Führungsrohr befindet sich ein längsbeweglicher Anker 2, der vom festsitzenden gegenüberliegenden Polkern 3 angezogen ist. Am Übergang des zu einem Kegel ausgebildeten Ankerteils ist eine Rille eingedreht, in welcher der elastische Dämpfungsring 4, der als O-Ring aus Simrit, Gummi oder dergleichen besteht, eingebettet ist. Seine Materialstärke bestimmt die Größe des Abstandes zwischen Anker und Kern, sein Werkstoff die Schlagdämpfung des Magnetankers auf den Kern und somit auch eine Geräuschdämpfung des Elektromagneten.1 with the guide tube designed as a hollow cylinder for receiving and guiding the fixed and moving parts designated. There is a longitudinally movable one in the guide tube Armature 2, which is attracted to the fixed opposite pole core 3. At the transition from to one Conical armature part is screwed into a groove in which the elastic damping ring 4, which is an O-ring made of Simrit, rubber or the like, is embedded. Its material thickness determines the size of the distance between armature and core, its material is the shock absorption of the magnet armature on the core and thus also noise reduction of the electromagnet.
