Claims (7)

1. Kurzschlußscheibe gemäß Beschreibung, dadurch gekennzeichnet, daß ein oder mehrere Kontaktdrähte aus einer spez. Edelmetalllegierung unter Eigenfeder­ vorspannung in der gemäß Fig. I und Fig. III dargestellten Weise gegen einen Wälzlager­ innenring anlaufen ohne daß es zur Ausbildung eines trennenden Schmierfilmes in der Kontaktfläche kommt.1. Short-circuit disc as described, characterized in that one or more contact wires from a spec. Noble metal alloy under its own spring bias in the FIG. I and III manner shown Fig. Inner ring move against a rolling bearing without causing the formation of a separating lubricating film in the contact surface. 2. <KSS< nach Anspruch 1, dadurch gekennzeichnet, daß die Verbindung des Kontaktdrahtes (3) mit dem Kontaktdrahtträgerblech (1) mittels einer Querlochklemmschraube (4 + 5) erfolgt.2. <KSS <according to claim 1, characterized in that the connection of the contact wire ( 3 ) with the contact wire support plate ( 1 ) by means of a cross hole clamping screw (4 + 5). 3. <KSS< nach Anspruch 1, dadurch gekennzeichnet, daß ein oder mehrere Federlaschen (2) fest mit dem Kontaktdrahtträgerblech (1) in der gemäß Fig. I dargestellten Weise verbunden sind.3. <KSS <according to claim 1, characterized in that one or more spring tabs ( 2 ) are firmly connected to the contact wire support plate ( 1 ) in the manner shown in FIG. I. 4. <KSS< nach Anspruch 1, dadurch gekennzeichnet, daß optional alle Flächen des Kontaktdrahtträgerbleches (1) und der Federlaschen (2) mit einer elektrisch gut leitenden Beschichtung versehen sind (z. Bsp. Versilbern, verkupfern), um die Übergangswiderstände zu reduzieren.4. <KSS <according to claim 1, characterized in that optionally all surfaces of the contact wire support plate ( 1 ) and the spring tabs ( 2 ) are provided with an electrically highly conductive coating (z. B. Silvering, copper) to reduce the contact resistance . 5. <KSS< nach Anspruch 1, dadurch gekennzeichnet, daß alle Freiräume (6) optional zusätzlich mit leitendem Fett (Standardfett + Silberpulver) befüllt werden, um den Übergangswiderstand noch weiter zu reduzieren.5. <KSS <according to claim 1, characterized in that all free spaces ( 6 ) are optionally additionally filled with conductive grease (standard grease + silver powder) in order to reduce the contact resistance even further. 6. <KSS< nach Anspruch 1, dadurch gekennzeichnet, daß bei offenen, nicht abgedichteten Lagern eine Kontakt-Schutzkappe (12) mit integrier­ ter Dichtlippe vorgesehen wird, um den Kontaktpunkt vor nicht-leitendem Fett aus dem Lagerbereich zu schützen.6. <KSS <according to claim 1, characterized in that in the case of open, unsealed bearings, a contact protective cap ( 12 ) with an integrated sealing lip is provided in order to protect the contact point from non-conductive grease from the bearing area. 7. <KSS< nach Anspruch 1, dadurch gekennzeichnet, daß die <KSS< auch fest mit dem Lageraußenring leitend verbunden sein kann. (z. Bsp. mittels leitendem Kleber oder Lötung)7. <KSS <according to claim 1, characterized in that the <KSS <can also be permanently connected to the bearing outer ring. (e.g. using conductive glue or soldering)
