Description

Zur Übertragung von Drehmomenten zwischen Wellen, deren Achsen sich unter einem Winkel schneiden, sind Gelenkkupplungen verschiedener Ausführungen bekannt. Für die Verbindung zweier sich räumlich kreuzender oder gegeneinander beweglicher Wellen verwendet man in der Regel eine Zwischenwelle, die mit den beiden Wellen durch je eine derartige Gelenkkupplung verbunden wird. Bei elektrischen Fahrzeugen mit nicht geerdetem Wagenkasten, wie z. B. Oberleitungsbussen u. dgl., die mit derartigen Gelenkwellen ausgerüstet sind, ist die Anordnung einer zusätzlichen Isolierkupplung erforderlich.For the transmission of torques between shafts whose axes are Cut at an angle, articulated couplings of various designs are known. For the connection of two spatially intersecting or mutually movable Shafts one usually uses an intermediate shaft that connects to the two shafts is connected by such a joint coupling. With electric vehicles with ungrounded car body, such as B. trolleybuses and the like Cardan shafts are equipped with an additional isolating coupling necessary.

Der Erfindung liegt die Aufgabe zugrunde, einen für derartige Zwecke verwendbaren Antrieb zu schaffen, der die Anordnung einer zusätzlichen Isolierkupplung überflüssig macht. -Die Erfindung macht dabei Gebrauch von einer Kupplung, bei der ein Pendellager, insbesondere Pendelkugel- oder -rollenlager, zur gegenseitigen Zentrierung der beiden Wellen und Federelemente in Form von Gummikörpern für die Drehmomentübertragung vorgesehen sind.The invention is based on the object of one for such purposes To create a usable drive, the arrangement of an additional isolating coupling makes redundant. -The invention makes use of a coupling in which a self-aligning bearing, in particular self-aligning ball or roller bearings, for mutual Centering of the two shafts and spring elements in the form of rubber bodies for the Torque transmission are provided.

Gemäß der Erfindung wird bei einer solchen Kupplung das Pendellager mittels isolierender Einlagen isoliert eingesetzt, wodurch sich in Verbindung mit den Gummikörpern für die Drehmomentübertragung eine einwandfreie elektrische Isolierung zwischen den miteinander zu kuppelnden Wellen ergibt.According to the invention, the self-aligning bearing is used in such a coupling insulated by means of insulating inserts, whereby in connection with the rubber bodies for torque transmission have perfect electrical insulation between the shafts to be coupled together.

Zur Erläuterung der Erfindung dient die Zeichnung, die ein Ausführungsbeispiel einer Verbindung zwischen zwei zueinander liegenden beweglichen Wellen mittels einer Zwischenwelle, die durch j e eine Kupplung gemäß der Erfindung mit den beiden Wellen verbunden ist, darstellt.The drawing, which shows an exemplary embodiment, serves to explain the invention a connection between two mutually lying movable shafts by means of a Intermediate shaft, which by j e a coupling according to the invention with the two shafts is connected, represents.

Die Wellen I und I' sind durch die Zwischenwelle 2 dreh- und winkelelastisch miteinander verbunden. Die Zwischenwelle ist dabei gegenüber den Wellenenden I und I' durch je ein Pendelkugellager 3 bzw. 3' zentriert. Die Drehmomentübertragung zwischen der Zwischenwelle 2 und den auf die Wellenenden aufgesetzten Kupplungsflanschen 4 und 4' erfolgt über eine Anzahl, z. B. vier, isolierender Gummiteile 5 und 5', die eine elastische Verdrehung und Winkelbewegung der Wellen gestatten. Sie werden zweckmäßig mit tangentialer Vorspannung eingesetzt und von Fall zu Fall den Betriebsverhältnissen angepaßt. Gemäß der Erfindung sind die Lager 3 und 3' durch isolierende Einlagen 6 und 6' gegenüber der Zwischenwelle isoliert. Diese Isoliereinlagen ergeben zusammen mit den Gummielementen 5 und 5' eine elektrische Trennung der beiden Wellen r und r'.The shafts I and I 'are torsionally and angularly elastic due to the intermediate shaft 2 connected with each other. The intermediate shaft is opposite the shaft ends I and I 'centered by a self-aligning ball bearing 3 or 3'. The torque transmission between the intermediate shaft 2 and the coupling flanges placed on the shaft ends 4 and 4 'takes place via a number, e.g. B. four, insulating rubber parts 5 and 5 ', which allow elastic rotation and angular movement of the shafts. you will be expediently used with tangential preload and depending on the operating conditions on a case-by-case basis customized. According to the invention, the bearings 3 and 3 'are provided with insulating inserts 6 and 6 'isolated from the intermediate shaft. These insulators result together with the rubber elements 5 and 5 'an electrical separation of the two shafts r and r '.

Bei dem dargestellten Beispiel ist die Zwischenwelle mit angeformten Flanschen versehen, die die Pendellager aufnehmen und die Befestigungsteile für die Federelemente tragen. Statt dessen können aber auch auf die Enden der Welle aufgesetzte gesonderte Kupplungsflansche verwendet werden.In the example shown, the intermediate shaft is also integrally formed Provided flanges that accommodate the self-aligning bearings and the fasteners for the spring elements carry. Instead, you can also use the ends of the shaft Separate attached coupling flanges can be used.
