  Anordnung zur Bewegungsübertragung durch auf Wellen sitzende
Schlingfedern 
Die Erfindung betrifft eine Anordnung zur Bewegungsttbertragung durch auf Wellen sitzende Schling- federn. 



   Bisher war es üblich, Bauteile auf Wellen mittels Schlingfedern zu befestigen, die innerhalb des zu befestigenden Bauteiles angeordnet und deren beide Enden zu Kupplungszwecken abgebogen waren. 



  Einerseits durfte in diesem Falle die Länge des Bauteiles ein gewisses Minimum nicht unterschreiten, da- mit nicht etwa die kraftschlüssige Wirkung der Schlingfedern verlorenging, anderseits war ein Abnehmen des befestigten Bauteiles erst nach vorherigem Biegen eines Kupplungsendes der Feder möglich, was bei mehrmaligem Abnehmen die Gefahr der Zerstörung der Schlingfeder mit sich brachte. Einer andern bekannten Ausführung zufolge waren zwei auf beiden Seiten eines Bauteiles mit diesem in Eingriff stehende Schlingfedern vorgesehen, so dass beim Abnehmen des Bauteiles stets erst eine Feder entfernt werden musste. 



   Im übrigen waren bei den bekannten Ausführungen zur Bewegungsübertragung in jedem Falle durch die Schlingfedern gehaltene Bauteile erforderlich, was in vielen Fällen, besonders in der Feinmechanik, vermieden werden könnte. 



   Die Erfindung schafft eine auf Schlingfedern beruhende verbesserte Anordnung zur   Bewegungstiber-   tragung. Erfindungsgemäss wird dies dadurch erreicht, dass eine mittlere Windung der Schlingfeder als aus dem äusseren Federdurchmesser ragende Schlaufe ausgebildet ist. Auf diese Weise ergibt sich einerseits eine vorteilhafte Verbindung von erforderlichen Bauteilen und anderseits kann die Verwendung bestimmter, besonderer Bauteile zur Bewegungsübertragung entfallen, zumindest für die Falle, wo es-wie z. B. in der   Feinmechanik - gentigt,   mit einer Hebelwirkung auszukommen. 



   Die Einzelheiten der Erfindung sind aus dem folgenden Ausführungsbeispiel zu ersehen. Es zeigen Fig. 1 die besondere Ausbildung einer Schlingfeder und Fig. 2 eine Seitenansicht zu Fig. 1. 



   Auf der Welle 1 sitzt die Schlingfeder 2. Eine der mittleren Windungen der Schlingfeder 2 ist als Schlaufe 3 gestaltet. Damit ergibt sich ein auf der Welle 1 festsitzender Hebel, der relativ leicht zu befestigen ist. Dieser Hebel kann unmittelbar auf weitere Teile einer Getriebekette wirken.

  Arrangement for the transmission of motion by people sitting on shafts
Wrap springs
The invention relates to an arrangement for the transmission of movement by wrap springs seated on shafts.



   Up to now it has been customary to fasten components on shafts by means of wrap springs, which are arranged within the component to be fastened and both ends of which were bent for coupling purposes.



  On the one hand, the length of the component was not allowed to fall below a certain minimum in this case, so that the force-locking effect of the wrap springs was not lost; on the other hand, the attached component could only be removed after one of the coupling ends of the spring had been bent, which is dangerous if it is removed several times brought about the destruction of the coil spring. According to another known embodiment, two wrap springs that were in engagement with a component were provided on both sides of the component, so that when the component was removed, one spring always had to be removed first.



   In addition, in the known designs for the transmission of motion, components held by the wrap springs were required in each case, which could be avoided in many cases, especially in precision engineering.



   The invention creates an improved arrangement based on loop springs for transmitting movement. According to the invention, this is achieved in that a central turn of the loop spring is designed as a loop protruding from the outer spring diameter. In this way, on the one hand, there is an advantageous connection of the required components and, on the other hand, the use of certain special components for the transmission of motion can be dispensed with, at least for the case where there is a need, such as B. in precision engineering - enough to get by with leverage.



   The details of the invention can be seen from the following exemplary embodiment. 1 shows the particular design of a loop spring and FIG. 2 shows a side view of FIG. 1.



   The wrap spring 2 sits on the shaft 1. One of the central turns of the wrap spring 2 is designed as a loop 3. This results in a lever which is stuck on the shaft 1 and which is relatively easy to attach. This lever can act directly on other parts of a transmission chain.
