1 (
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, dass das Lager oder der Träger an zumindest drei Fixierpunkten die Fixiermittel aufweist, wobei jeder der drei Fixierpunkte eine Ecke eines gedachten regelmäßigen Vielecks bildet, so dass das Lager zum Einstellen der Stützweite des Antriebsstranges in zumindest drei unterschiedlichen Drehstellungen an dem Träger fixierbar ist.These Task is according to the invention solved by that the bearing or the carrier at at least three fixing points, the fixing means, wherein each of the three fixation points a corner of an imaginary regular polygon forms, allowing the bearing to adjust the span of the drive train can be fixed to the carrier in at least three different rotational positions is.
Bei einer derartigen Ausgestaltung können im Unterschied zu den genannten bekannten Antriebssträngen mehr als zwei unterschiedliche Werte für die Kontaktkraft eingestellt werden, ohne das Lager selbst wechseln zu müssen.at Such a configuration can in Difference to the mentioned known drive trains more set as two different values for the contact force without changing the warehouse itself.
In bevorzugter Ausgestaltung des neuen Kontaktträgers ist vorgesehen, dass als Lager eine Exzenterplatte vorgesehen ist, deren Querschnittsfläche ein regelmäßiges Vieleck bildet, so dass die seitlichen Kanten der Exzenterplatte die Fixierelemente der Exzenterplatte in Form von ersten Anschlägen bilden und dass die Fixierelemente des Trägers von zweiten Anschlägen gebildet sind, an denen die Anschläge der Exzenterplatte formschlüssig anliegen. Hierbei kann der Träger eine zu dem Lager komplementäre Ausnehmung aufweisen, wobei die seitlichen Innenflächen der Ausnehmung die zweiten Anschläge bilden.In preferred embodiment of the new contact carrier is provided that as Bearings an eccentric plate is provided, whose cross-sectional area a regular polygon forms, so that the lateral edges of the eccentric plate, the fixing elements form the eccentric plate in the form of first stops and that the fixing elements of the carrier from second attacks are formed, against which the attacks of the eccentric plate fit. Here, the carrier one complementary to the camp Have recess, wherein the lateral inner surfaces of the Recess the second attacks form.
Vorteilhaft ist es weiterhin, wenn zum Halten der Koppelachse zumindest zwei der Lager vorgesehen sind.Advantageous It is also, if at least two to hold the coupling axis the bearings are provided.
Um – wie schon
bei dem aus der Druckschrift
Um dem Benutzer weiterhin ein ordnungsgemäßes Einstellen einer gewünschten Stützweite des Antriebsstranges und damit eines gewünschten Wertes der Kontaktkraft zu erleichtern, können der Träger und das Lager mit einander zugeordneten Markierungen versehen sein.Around the user continues to properly set a desired span the drive train and thus a desired value of the contact force to facilitate the carrier and the bearing be provided with associated markings.
Der neue Kontaktträger ist mit Vorteil in Niederspannungs-Leistungsschaltern einsetzbar, und zwar beispielsweise um in montagetechnische einfacher Weise und dabei insbesondere ohne den Austausch von Bauteilen eine Anpassung an zumindest drei verschiedene Schaltleistungsklassen durch Einstellen einer entsprechenden Kontaktkraft vorzunehmen.Of the new contact carrier is used with advantage in low-voltage circuit breakers, namely For example, in assembly technology simple way and thereby especially without the replacement of components an adaptation at least three different switching power classes by setting to make an appropriate contact force.
