Description

Die Schleuderfeder der elektrischen Drehschalter mit Rechts- und Linksgang ist meistens um die Achse des Schalters gewickelt und besitzt an beiden Enden abgebogene Schenkel, welche einerseits an einem mit der Achse fest verbundenen Mitnehmer und anderseits an dem Körper der Schalttronimel anliegen.The centrifugal spring of the electric rotary switch with right and left gear is mostly wrapped around the axis of the switch and has bent ends at both ends Legs, which on the one hand on a driver firmly connected to the axis and on the other hand on the body of the switching drum issue.
Wird beim Drehen des Schaltergriffes 1 dieIf the switch handle 1 is turned
ίο Feder gespannt, so geschieht dies dadurch, daß der eine Schenkel 2 durch den mit der Achse fest verbundenen Mitnehmer 3 von der Anlagestelle 4 an dem Schaltkörper abgehoben wird. Hierbei wird die Feder um-die Achse herumgespannt, wobei sich zum Teil ihr Windungsdurchmesser verringert. Durch das einseitige Angreifen der drehenden Kraft an der Feder wird die letztere aus ihrer ursprünglichen Lage etwas verschoben, so daß sie dann meistens schief steht und die letzten Windungen an dem durch den Mitnehmer abgelenkten Ende 5 der Feder sich stark an der Schalterachse reiben. Durch diese Reibung wird der Federdraht erheblich, geschwächt, so daß ein vorzeitiger Bruch der Feder an dieser Stelle eintritt.ίο the spring is tensioned, this is done by that the one leg 2 by the driver 3 firmly connected to the axis of the Contact point 4 is lifted off the switch body. Here the spring is about the axis stretched around, whereby their coil diameter is reduced in part. By the Unilateral attack of the rotating force on the spring removes the latter from its original one Position shifted a bit so that it is then mostly crooked and the last turns on the one deflected by the driver End 5 of the spring rub heavily on the switch shaft. This friction weakens the spring wire considerably, so that a premature breakage of the spring occurs at this point.
Bei den bereits bekannten Ausführungen von Schleuderfedern hat man versucht, durch, entsprechende Biegung der Schenkel das Verschieben der Feder zu verhindern; aber auch diese Bemühungen können nicht zu einem vollen Erfolg führen.In the case of the already known designs of centrifugal springs, attempts have been made to appropriate bending of the legs to prevent displacement of the spring; but also these efforts cannot lead to complete success.
Durch die Erfindung werden die vorgenannten Übelstände restlos beseitigt, und zwar dadurch, daß die Windungen der in Form einer Schraubenfeder gewickelten Feder in der Mitte einen größeren Durchmesser besitzen als an den beiden Enden. Infolge der weicheren Federung der mittleren Windungen können sich dann die letzten Windungen an den beiden Enden der Feder in ihrem Windungsdurchmesser nicht verändern. Es ist also nicht mehr möglich, daß infolge des Zusammenziehens der Feder an den Enden die letzten Windungen sich, an der Achse reiben.The invention completely eliminates the abovementioned inconveniences, namely in that the turns of the coil spring wound in the middle have a larger diameter than the two ends. As a result of softer suspension of the middle turns can then be applied to the last turns Do not change the coil diameter of the two ends of the spring. So it is no longer possible that as a result of the contraction The last turns of the spring at the ends rub against the axle.
