Abstract
Description
Das technische Gebiet, zu dem die Erfindung gehört, ist Schirmung oder Abschirmung von Gegenständen.The technical field to which the invention belongs is Shielding or shielding objects.
Stand der Technik sind auf dem Gebiet der Dichtungstechnik an bewegten Teilen von Schirmungen Hohlleiterdämpfungs glieder oder wellenförmige Dämpfungsglieder für Regler achsen, wie sie in Standard oder Sonderlösung, in elektro Automation, 48. Jahrgang, Nr. 7, Juli 1995, Seite 48 und 50 oder in der Patentanmeldung 195 28 764.9-34 oder in H.Meincke/F.W. Gundlach, Taschenbuch der Hochfrequenztechnik, 3. verbesserte Auflage, 1968, Seite 312 beschrieben werden, zur Abdichtung von Wellen und Stößeln an Schirmungen und die, in der Patentanmeldung 195 28 764.9-34 beschrie benen, Schirmungen mit bewegten flexiblen schirmenden Gegenständen sowie die in der Patentanmeldung 195 28 764.9-34 aufgezeigte Möglichkeit der Schirmung mit gegeneinander bewegten schirmenden Überdeckungen. Stand der Technik auf dem Gebiet der schirmenden Dichtungen an relativ zueinander ruhenden Teilen sind die in Standard oder Sonderlösung, in elektro Auto mation , 48. Jahrgang, Nr. 7, Juli 1995, Seite 48 und 50 aufgeführten sägeartigen Kontaktfinger.State of the art in the field of sealing technology on moving parts of shielding waveguide damping links or wave-shaped attenuators for controllers axes, as in standard or special solutions, in Elektro Automation, 48th year, No. 7, July 1995, Page 48 and 50 or in the patent application 195 28 764.9-34 or in H.Meincke / F.W. Gundlach, Taschenbuch der Hochfrequenztechnik, 3rd improved Edition, 1968, page 312, for sealing shafts and plungers on shields and which, described in patent application 195 28 764.9-34 planes, shields with moving flexible shield ends Objects as well as those in the patent application 195 28 764.9-34 shown possibility of shielding with shielding covers moving against each other. State of the art in the field of shielding Seals on parts that are relatively stationary those in standard or special solution, in electric car mation, 48th year, No. 7, July 1995, page 48 and 50 listed saw-like contact fingers.
Das der Erfindung zugrundeliegende Problem ist die schirmende Abdichtung von physikalischen oder elek trischen oder magnetischen Feldern oder Strahlungen oder Strahlen oder Wellen an relativ zueinander be wegten oder ruhenden Teilen an einer geerdeten oder nicht geerdeten Schirmung.The problem underlying the invention is shielding sealing of physical or elec trical or magnetic fields or radiation or rays or waves on relative to each other moved or stationary parts on a grounded or ungrounded shielding.
Die Erfindung für die Schutz begehrt wird, sind schir mende Dichtungen an relativ zueinander bewegten schir menden Teilen, die diese Teile berühren und schirmende Dichtungen an relativ zueinander ruhenden schirmenden Teilen mit einem Trennspalt, dessen Quer schnitt über die Länge nicht konstant ist, jeweils für Schirmungen von elektrischen oder magnetischen oder physikalischen Strahlen oder Strahlungen oder Feldern oder Wellen.The invention for which protection is sought are shir sealing seals on relatively moving screen parts touching these parts and shielding seals on relatively dormant shielding parts with a separation gap whose cross cut across the length is not constant, respectively for shielding from electrical or magnetic or physical rays or radiations or fields or waves.
Der Gegenstand der Erfindung ist auf dem Gebiet der Ab schirmung von Geräten und Gegenständen auf dem Gebiet der physikalischen oder chemischen oder biologischen Technik einsetzbar.The object of the invention is in the field of Ab shielding of devices and objects in the field of physical or chemical or biological technology applicable.
Durch die Verwendung der, in dieser Erfindung beschrie benen , Dichtungen können schirmende Öffnungen platz sparender und effektiver gebaut werden, als mit den oben angeführten Hohlleiterdämpfungsgliedern. Beispielsweise kann durch die unten erwähnten Wasserringdichtungen eine, im Gegensatz zu kurzen Hohlleiterdämpfungsgliedern, vollkommene Schirmung für alle Frequenzen bei gleicher Baulänge, für den Fall der Schirmung von magnetischen Feldern, erreicht werden.By using the, described in this invention levels, seals can place shielding openings be built more economically and efficiently than with the above listed waveguide attenuators. For example can by the water ring seals mentioned below one, in contrast to short waveguide attenuators, perfect shielding for all frequencies at the same Overall length, in the case of shielding from magnetic Fields.
Wege zum Ausführen der Erfindung sind die in Tochtermann/Ferdinand Bodenstein, Konstruktionselemente des Maschinenbaues, neunte, verbesserte Auflage, Springer Verlag, 1979, Teil 1 auf Seite 238 in Abb. 3.61 dargestellten Kolbenringe und die ebenda auf Seite 243 in Abb. 3.68 dargestellte Wasserringdichtung, die Beispiele zu Patentanspruch 1 sind, oder die Labyrinth- oder Labyrinthspaltdichtungen die ebenda auf Seite 241-243 in Abbildungen von Abb. 3.66 bis Abb. 3.67 dargestellt werden, und die Beispiele zu Patentan spruch 2 sind, wobei bei all diesen Beispielen sowohl die Dichtungen als auch die diese dichtenden Teile schirmend sein müssen. Die angesprochenen Beispiele sind für die Verwendung bei Schirmungen neu.Ways of carrying out the invention are as shown in Daughter / Ferdinand Bodenstein, construction elements of mechanical engineering, ninth, improved edition, Springer Verlag, 1979, part 1 on page 238 in Fig. 3.61 piston rings shown and the same on page 243 Water ring seal shown in Fig. 3.68, the Examples of claim 1 are, or the labyrinth or labyrinth gap seals the same on page 241-243 in figures from Fig. 3.66 to Fig. 3.67 and the examples of Patentan are 2, with all of these examples both the seals as well as the parts that seal them must be shielding. The examples mentioned are new for use in shielding.
