Description
In dem Patent 939 451 ist eine Kurbelanordnung für Fahrschalter bei elektrischen Fahrzeugen, insbesondere Straßenbahnwagen, elektrischen Lokomotiven od. dgl., angegeben, bei der die in zwei Lagern. gelagerte Kurbelachse in eine Lagerbuchse hineinragt. Die Erfindung stellt eine weitere Verbesserung einer solchen Werkstoff und Platz sparenden Kurbelanordnung dar und zeichnet sich im wesentlichen dadurch aus, daß in der als Lagerung für den Blockierungshebel dienenden Lager-Buchse beide Lager für die Kurbelachse untergebracht sind. Da hierbei nur ein einziges Spiel --und zwar zwischen der Kurbelachse und der Lagerbuchse --- vorhanden ist, ist eine sichere Kurbelachsenlagerung gewährleistet, welche von Herstellungsungenauigkeiten des äußeren Lagerbuchsendurchmessers und der Bohrung des Blockierungs-Nebels unabhängig ist.In patent 939,451 a crank assembly for travel switches is at electric vehicles, in particular trams, electric locomotives Od. Like. Specified in which the two camps. mounted crank axle in a bearing bush protrudes. The invention represents a further improvement in such a material and space-saving crank arrangement and is essentially characterized by it from that both in the bearing bushing serving as a storage for the blocking lever Bearings for the crank axle are housed. There is only one game here - namely between the crank axle and the bearing bush --- is present, is one safe crank axle bearing ensures that there are no manufacturing inaccuracies of the outer bearing bush diameter and the bore of the blocking mist independently is.
In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt.In the drawing, the invention is shown in one embodiment.
Mit i ist die Kurbel bezeichnet, deren Achse 2 mit Hilfe zweier Kugellager 3 und 7 gelagert ist, die in dem erweiterten Teil einer Lagerbuchse 5 untergebracht sind. Die Lagerbuchse 5 ist an einer oberen Platte 4 eines z. B. rahmenartigen Fahrschalterträgers befestigt und an ihrem mittleren Teil abgedreht, so daß sie zugleich als Lager für den Blockierungshebel 6 dient.The crank is denoted by i, the axis 2 of which with the aid of two ball bearings 3 and 7 is mounted, which is housed in the enlarged part of a bearing bush 5 are. The bearing bush 5 is attached to an upper plate 4 of a z. B. frame-like travel switch support attached and turned off at its middle part, so that it can also be used as a warehouse for the blocking lever 6 is used.
Die Lagerbuchse 5 weist eine nicht näher bezeichnete Rille auf, in die ein am Blockierungs-Nebel 6 befestigter Winkel 8 oder ein eingeschraubter zylindrischer Zapfen eingreift. Auf diese Weise wird der Blockierungshebel6 in seiner Höhenlage festgehalten, ohne daß seine Drehbewegung gehindert ist.The bearing bush 5 has a groove, not shown in detail, in an angle 8 attached to the blocking mist 6 or a screwed-in cylindrical one Pin engages. In this way, the locking lever 6 is in its height position held without its rotation is hindered.
An Stelle von Kugellagern können sinngemäß beliebige andere Lager, z. B. Rollen- oder Nadel-. Lager, verwendet werden.Instead of ball bearings, any other bearings, z. B. roller or needle. Bearings, can be used.
