Kugel -Bullet -

Eines der Hindernisse bei Anwendung von oder Rollenlagern bei elektrischen Rollen- oder Walzen-Stromabnehmern ist, dafs solche Lager nur mit tadellos glatten Kugeln oder Rollen und Lagerflächen gut arbeiten. Der vom drehenden Theil des Contactes durch das Zapfenlager in den ruhenden Theil oder umgekehrt fiiefsende Strom verbrennt jedoch stellenweise die rollenden Flächen des Lagers. Besonders wenn während des Stehens ein starker Strom abgenommen wird, so werden die rollenden Flächen erweicht, worauf eine rasche Abnutzung des Lagers, eintritt.One of the obstacles in using or rolling bearings in electrical Roller or cylinder current collectors are, that such bearings only with perfectly smooth balls or castors and storage areas work well. The one from the rotating part of the contact the journal bearing in the resting part or vice versa, however, burns up in places the rolling surfaces of the warehouse. Especially if one while standing If a strong current is removed, the rolling surfaces are softened, whereupon a rapid wear of the bearing occurs.

Diesem Uebelstande sollte beispielsweise die englische Patentschrift 18718 v. J. 1897 durch parallel zu den Kugellagern geschaltete Schleifcontacte abhelfen. Der erstrebte Zweck dürfte jedoch auf diese Art nicht erreicht worden sein, da immerhin noch ein Theil des Gesammtstromes durch die Kugellager fliefst.The English patent specification 18718 v. Chr. J. 1897 by Grinding contacts connected in parallel to the ball bearings help. The intended purpose is likely but could not have been reached in this way, since still a part of the total flow flowing through the ball bearings.

Durch vorliegende Erfindung soll diesem Uebelstande dadurch abgeholfen werden, dafs der Weg des Stromes durch das Lager mittelst Isolation unterbrochen wird. Dieses geschieht in der Weise, dafs das Lager selbst aus elektrisch isolirendem Material verfertigt wird, oder dadurch, dafs das Lager entweder vom ruhenden Theile oder vom drehbaren Theile, oder auch von beiden Theilen isolirt wird, während der Strom vom drehbaren Theile in den ruhenden oder umgekehrt mittelst eines besonderen dazu geeigneten Contactes geleitet wird.The present invention is intended to remedy this inconvenience in that the path of the current through the camp is interrupted by means of insulation. This happens in such a way that the bearing itself is made of electrically insulating material, or in that the bearing either comes from the stationary part or from the rotatable part, or is also isolated from both parts, while the current from the rotatable part into the dormant or vice versa by means of a special suitable contact will.

Eine Ausführungsform dieser Anordnung ist aus der beiliegenden Zeichnung ersichtlich.An embodiment of this arrangement can be seen from the accompanying drawing.

Ein Walzeiicontact α mit konischem Ende b ist auf zwei Kugellagern c c, welche auf einem Metallrohr d befestigt sind, gelagert. Das Metallrohr d ist auf eine isolirende, etwa aus Holz verfertigte Stange e gesteckt. Zwischen der Walze α b und dem ruhenden Theil des Stromabnehmers stellt ein besonderer, ringförmiger, etwa aus Kohle oder Graphit bestehender Gleitcontact g, welcher sich an das entsprechend geformte Ende des konischen Stückes anschmiegt und an dasselbe mittelst einer Feder f angedrückt wird, die leitende Verbindung her.A roller contact α with a conical end b is mounted on two ball bearings cc, which are fastened to a metal tube d. The metal tube d is placed on an insulating rod e made for example of wood. Between the roller α b and the stationary part of the current collector, a special, ring-shaped sliding contact g , made for example of carbon or graphite, which clings to the correspondingly shaped end of the conical piece and is pressed against it by means of a spring f, provides the conductive connection here.

Dieselbe Einrichtung ist auch für Stromabnehmer mit mehreren Walzen geeignet, wie dies aus Fig. 2 ersichtlich ist, woselbst die einzelnen Contactstücke mit a, die Stellen, wo sich die Kugellager befinden, mit χ bezeichnet sind.The same device is also suitable for current collectors with several rollers, as can be seen from FIG. 2, where the individual contact pieces are designated with a, the points where the ball bearings are located with χ .

Claims (1)

Patent-An spruch:
Ein Stromabnehmer für elektrische Bahnen mit Kugel- oder Rollenlagern, dadurch gekennzeichnet, dafs die Lager von den elektrisch leitenden Theilen der ruhenden oder bewegten Organe oder von beiden elektrisch isolirt sind, oder dafs die Lager selbst aus nicht leitendem Materiale bestehen, wobei besondere Contacte (g) zur Wiederherstellung des durch erwähnte Isolation unterbrochenen Stromkreises dienen.
Patent claim:
A current collector for electric railways with ball or roller bearings, characterized in that the bearings are electrically isolated from the electrically conductive parts of the stationary or moving organs or from both, or that the bearings themselves consist of non-conductive materials, with special contacts (g ) serve to restore the circuit interrupted by the insulation mentioned.
