Abstract

Das Drehpotentiometer besitzt eine Trägerplatte (1), auf der sich eine innere ringförmige Schleiferbahn und eine äußere hufeisenförmige Widerstandsbahn befindet. Die Anschlußenden (4, 5) der Schleifer- und der Widerstands­ bahn sind an einer Seitenkante der Trägerplatte (1) angeord­ net. Die Schleifkontakte (6) sind über einen Mitnehmer (7) mit einem Stellglied (14) verstellbar. Ein solches Potentiome­ ter soll einerseits einfach ohne Nietvorgänge montierbar und außerdem mit dem Stellglied (14) leicht kuppelbar sein. Hierzu besitzt der Mitnehmer (7) eine Drehwelle (13) die über einen radialen Steg (9) mit der Peripherie des Mitnehmers (7) derart verbunden ist, daß die Drehwelle (8) axial bewegbar ist. Das zur Trägerplatte (1) gerichtete freie Ende der Drehwelle (8) wird durch einen Längsschlitz (10) gespalten zu einer drehbaren Rastverbindung. Diese ist in einer zentralen Bohrung (11) der Trägerplatte (1) gelagert. Das andere freie Ende (13) der Drehwelle (8) ist mit dem Stellglied (14) kuppelbar. The rotary potentiometer has a support plate (1) which is an inner ring-shaped grinding track and a outer horseshoe-shaped resistance track is located. The Terminal ends (4, 5) of the grinder and resistor web are arranged on a side edge of the carrier plate (1) net. The sliding contacts (6) are via a driver (7) adjustable with an actuator (14). Such a potentiome ter should be easy to assemble without riveting and also be easily coupled to the actuator (14). For this purpose, the driver (7) has a rotary shaft (13) which a radial web (9) with the periphery of the driver (7) is connected such that the rotary shaft (8) is axially movable is. The free end of the support plate (1) Rotary shaft (8) is split by a longitudinal slot (10) a rotatable locking connection. This is in a central Bore (11) of the support plate (1) stored. The other free The end (13) of the rotary shaft (8) is connected to the actuator (14) detachable.
