Description

Bei Telegrafengeräten, insbesondere bei Springschreibern. werden Reibungskupplungen verwendet, die durch den Antrieb ständig angetrieben werden, bei denen das getriebene Teil jedoch bis zur Auslösung durch einen Anschlag festgehalten wird. Derartige Reibungskupplungen bestehen meist aus Filzscheihen, gegen die unter Federdruck Metallscheiben gepreßt «-erden. Die Filzscheiben müssen dauernd geölt gehalten werden. Durch die dauernde Reibung entsteht jedoch ein Leistungsverlust, der in Wärme umgesetzt wird. Die Kupplungen zeigen einen erheblichen Drehmomentunterschied im kalten und armen Zustand.With telegraph equipment, especially with jump writers. become friction clutches used, which are constantly driven by the drive, in which the driven However, part is held until it is triggered by a stop. Such Friction clutches usually consist of felt strips against which metal disks are spring-loaded pressed "-ground. The felt discs must be kept oiled at all times. Through the However, constant friction results in a loss of power that is converted into heat. The clutches show a considerable difference in torque in the cold and poor State.

Die Erfindung schlägt eine trockene Reibungskupplung vor, bei der mindestens eine Reibscheibe aus Kohle oder Graphit besteht.The invention proposes a dry friction clutch in which at least one friction disk is made of carbon or graphite.

Versuche haben ergeben, daß das Drehmoment einer solchen Kupplung nicht nur im Bereich der Eigenerwärmung, sondern auch bei wechselnden äußeren Temperaturen gleichbleibt.Tests have shown that the torque of such a coupling not only in the area of self-heating, but also with changing external temperatures remains the same.

Zweckmäßig bestehen die anderen Reibscheiben aus einem Metall, vorzugsweise aus Stahl oder Grauguß, sie können aber ebenfalls aus Kohle bzw. in Metall gelagerten Kohlescheiben bestehen.The other friction disks are expediently made of a metal, preferably made of steel or cast iron, but they can also be made of carbon or metal Coal disks are made.

Gemäß weiterer Erfindung werden die Reibscheiben an den der Achse benachbarten Stellen mit Ausdrehungen versehen, um die Auflagepunkte in der Nähe der Achse auszuschalten und so ein gleichmäßigeres Drehmoment zu erreichen.According to a further invention, the friction disks are attached to the axle Provide notches to neighboring points to close the support points switch off the axis and thus achieve a more even torque.

In der Figur ist ein Ausführungsbeispiel der Erfindung dargestellt.In the figure, an embodiment of the invention is shown.

Die dauernd innlaufenden lletallreibscheiben i und 5, die auf der treibenden Welle 6 in der dargestellten Weise befestigt sind, besitzen Ausdr ehungen ; , so daß sie nur mit ihrem äußeren Umfang auf den Kohlereibscheiben 2 und 4 aufliegen. Die Ausdrehungen besitzen noch Lüftungslöcher 8 und 9 für die Wärmeabfuhr. Die Kohlereibscheiben 2 und .4 umschließen die _Mitnahmescheibe 3 des getriebenen Teils, die mit einem Anschlag io den Mitnehmer ii der getriebenen Welle 12 mitnimmt. Durch Bolzen 13 sind die Reibscheiben und die Mitnahmescheibe miteinander verbunden. Federn 14 drücken die ganze Kupplung zusammen. Die Kupplung ist durch Teile 15 und ii völlig gekapselt und wird zweckmäßig zum Schutz gegen kriechendes, Öl mit einer Kriechschutzlösung behandelt.The permanently internal lletallreibenscheiben i and 5, which are on the driving shaft 6 are attached in the manner shown, have Ausdr expansions ; so that they rest on the coal friction disks 2 and 4 only with their outer circumference. The notches still have ventilation holes 8 and 9 for heat dissipation. The coal grater discs 2 and .4 enclose the driving disk 3 of the driven part, which is connected to a Stop io takes the driver ii of the driven shaft 12 with it. By bolt 13 the friction disks and the drive disk are connected to one another. Press springs 14 the whole clutch together. The coupling is completely encapsulated by parts 15 and ii and is useful for protection against creeping oil with a creep protection solution treated.
