Drehwiderstand mit stromführender DrehachseRotary resistance with live axis of rotation

Bei der vorliegenden Erfindung handelt es sich um einen Drehwiderstand, wie er in großen Mengen "bei Radio- und Hachriehten-Geräten verwendet wird. Es sind zwei verschiedene 5ypen "bekannt. Bei der einen Ausführung ist die Schleiffeder von der Drehachse isoliert und bei der anderen Ausführung steht die Schleiffeder mit der Drehachse in elektrischer Verbindung und die Stromzuführung erfolgt über die Drehachse. Mit der zuletzt genannten Art befaßt sich die vorliegende Erfindung,The present invention is a rotary resistor, like him in large quantities "in radio and hi-fi devices is used. Two different types are known In one version, the slide spring is isolated from the axis of rotation and in the other version, the slide spring is connected to the The axis of rotation is electrically connected and the power is supplied via the axis of rotation. Dealt with the latter type the present invention,

Es sind viele Anordnungen für die axiale lagerung der Drehachse für die erwähnten Drehwiderstände bekannt geworden. Alle bisher bekannten Anordnungen haben aber gemeinsam, daß die zur Befestigung und zur !Führung der Drehachse dienende zentrale Lagerbuchse am Ende der Lagerbohrung einen zur Vernietung mit der tragplatte dienenden Ansatz besitzt. Der Eegelwiderstand gemäß vorliegender Erfindung weicht von dieser Bauart ab.There are many arrangements for the axial bearing of the axis of rotation for the rotary resistors mentioned are known. All so far but known arrangements have in common that the fastening and for guiding the axis of rotation, the central bearing bushing at the end of the bearing bore, one for riveting to the support plate serving approach. The level resistance according to the present Invention deviates from this type of construction.

In beiliegender Zeichnung ist die Erfindung dargestellt. Die Gewindebuchse (a) besitzt 2 Segmente (a') oder 2 Zapfen (a'') und wird durch deren Verformung mit der Grundplatte (b) die mit entsprechenden Ausspecrungen über die Segmente oder Zapfen gesteckt ist, vernietet. Zwischen Gewindebuchse (a) und Grundplatte (b) befindet sich die Lötöse (c) die in ihrem mittleren Teil verbreitert ist und dort einen Ausschnitt (e") besitzt, der in einer Ringnut (d') der Drehachse (d) eingreift und dadurch deren axiale Lagerung b ewirktlThe invention is shown in the accompanying drawing. The threaded bush (a) has 2 segments (a ') or 2 pins (a' ') and is deformed with the base plate (b) the corresponding Ausspecrungen is inserted over the segments or pegs, riveted. Located between the threaded bushing (a) and the base plate (b) the solder lug (c) which is widened in its middle part and there has a cutout (e ") in an annular groove (d ') engages the axis of rotation (d) and thereby affects its axial bearing

Die zur Vernietung dienenden Segmente (a') der GeYfindebuchse (a) entstehen durch Abfräsen des Gewindebuchsenflansches. Bei Verwendung einer Lagerbuchse aus Metallspritzguß werden zweckmäßig zylindrische Nietzapfen (a'') angeformt.The segments (a ') of the GeYfind bushing (a) used for riveting are created by milling off the threaded bushing flange. When using a bearing bush made of injection-molded metal, cylindrical ones are expedient Molded rivet pin (a '').
