Abstract
Zur Verhinderung der elektromagnetischen Emission wird ein Bremslager 1 angeben, dessen einer Reibpartner 18 von mindestens einer Lage 20 eines elektro-aktiven Polymers angetrieben wird.To prevent electromagnetic emission, a brake bearing 1 will be indicated, whose friction partner 18 is driven by at least one layer 20 of an electroactive polymer.
Description
Gebiet der ErfindungField of the invention
Die Erfindung befasst sich mit der Ausbildung von Bremslagern, insbesondere mit Aktuatoren, welche die jeweiligen Reibpartner in körperlichen Kontakt verbringen. The invention is concerned with the formation of brake bearings, in particular with actuators, which spend the respective friction partners in physical contact.
Gattungsmäßige Bremslager sind aus
In der Medizintechnik, insbesondere bei Computertomografen, werden hohe Anforderungen gestellt, die einen Eintrag von externen Magnetfeldern ausschließen. Daher sind Bremslager, deren Aktuatoren elektrische Spulen aufweisen, nur bedingt für Anwendungen in der Medizintechnik einsetzbar. In medical technology, especially in computer tomography, high demands are made, which exclude an entry of external magnetic fields. Therefore, brake bearings whose actuators have electrical coils can only be used to a limited extent for applications in medical technology.
Aufgabe der ErfindungObject of the invention
Es ist die Aufgabe der Erfindung, ein Bremslager anzugeben, deren Aktuatoren keine oder nur vernachlässigbare elektromagnetischen Emissionen verursachen.It is the object of the invention to provide a brake bearing whose actuators cause no or only negligible electromagnetic emissions.
Zusammenfassung der ErfindungSummary of the invention
Diese Ausgabe wird mit den in Anspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Aus- und Weiterbildungen der Erfindung sind den Ansprüchen 2 und 3 entnehmbar.This edition is achieved with the features specified in
Wird der auf eine der Reibpartner wirkende Aktuator von wenigstens einer Lage eines elektro-aktiven Polymers gebildet, sind die Emissionen eines solchen Aktuators so gering, dass diese Aktuatoren ohne besondere Abschirmmaßnahmen in der Medizintechnik oder ähnlichen – gegenüber elektromagnetischen Emissionen sensiblen – Anwendungen eingesetzt werden können. If the actuator acting on one of the friction partners is formed by at least one layer of an electroactive polymer, the emissions of such an actuator are so low that these actuators can be used without special shielding measures in medical technology or similar applications which are sensitive to electromagnetic emissions.
Eine sehr vorteilhafte und wenig aufwendige Ausbildung ist dann gegeben, wenn jede Lage des elektro-aktiven Polymers einen passiven Elastomerkern aufweist, der zwischen zwei elastischen Elektroden sandwichartig angeordnet ist, und wenn die beiden zu einer Lage gehörenden Elektroden schaltbar mit einer elektrischen Spannung verbunden sind.A very advantageous and less complicated training is given when each layer of the electro-active polymer has a passive elastomer core, which is sandwiched between two elastic electrodes, and when the two belonging to a layer electrodes are connected to a switchable electrical voltage.
Der Einsatz von elektro-aktiven Polymeren in der Form von dielektrischen Elastomeren als Aktuator ist dann besonders einfach, wenn jeder Elastomerkern einer jeden Lage zwei einander gegenüberliegende Randbereiche aufweist, wobei der eine Randbereich mit einem der Lagerringe zusammenwirkt und sich der andere Randbereich an dem Reibpartner abstützt, der dem Aktuator unmittelbar zugeordnet ist. Dies insbesondere deshalb, weil durch die Anordnung die natürliche Bewegung des Elastomerkerns unter wirkender Spannung ohne besondere Umlenkung ausgenutzt wird. The use of electro-active polymers in the form of dielectric elastomers as actuators is particularly simple if each elastomeric core of each layer has two mutually opposite edge regions, one edge region cooperating with one of the bearing rings and the other edge region being supported on the friction partner which is directly associated with the actuator. This is particularly because the arrangement exploits the natural movement of the elastomer core under effective tension without any special deflection.
