  Verbindung zwischen Welle und Nabe eines Maschinenantriebes zur Übertragung von Drehmomenten 
 EMI1.1

 der Welle   8,   anderseits an den Aussenflächen 9 der Schlitze 2 anliegender gewellter Blattfedern. 



     - Der fertigungsmässige   Aufwand für die Verbindung nach der Erfindung ist, was die eigentliche Bear- beitung anbelangt, verhältnismässig gering. Die Nabe der Antriebsscheibe ist mit einer zylindrischenBoh- rung zu versehen, während die Schlitze zur Aufnahme der gewellten Flachfedern mit ausreichender Genauigkeit im Druckgussverfahren bereits gegossen werden können. Etwa vorhandene geringe Massabwei- chungen werden von den Blattfedern ausgeglichen. Die Mitnehmerflächen 4 an der Welle 8 können bei
Anwendung von ein oder zwei Flächen auf einfache Weise in einem   Arbeitsgang gefräst oder geräumt   wer- den. 



   Das Aufbringen der Antriebsscheibe mit den darin unter der erforderlichen Vorspannung aufgenomme-   nenFlachfedem   auf die Welle kann mittels einer Aufpressvorrichtung erfolgen oder auch, wie in Fig. 2 der
Zeichnung dargestellt, mit Hilfe einer Sechskantschraube 6 und einer Druckscheibe 7, die dann zurSi- cherung der Verbindung an ihrem Sitz verbleiben kann. 



   Die   dargestellte Ausführung der Erfindung   stellt nur eine beispielsweise Verwirklichung derselben dar. 



   Die Anordnung kann auch so getroffen werden, dass nur ein Schlitz oder bei grösserem Wellendurchmes- ser je   nach Grösse   des zu übertragenden Drehmomentes mehrere Schlitze zur Aufnahme der Übertragungs- federn vorgesehen werden. 



   PATENTANSPRÜCHE : 
1. Verbindung zwischen Welle und Nabe eines Maschinenantriebes zur Übertragung von Drehmomen- ten, bei der die Welle an ihrem Umfang durch Wegnahme segmentartiger Teile entstandene Mitnehmer- flächen aufweist, an denen Übertragungsglieder anliegen, die in entsprechenden Schlitzen der Nabe ab- gestützt sind, dadurch gekennzeichnet, dass die in den Schlitzen der Nabe abgestützten und an den Mit- nehmerflächen der Welle anliegenden Übertragungsglieder gewellte Blattfedern (3) sind.

 the shaft 8, on the other hand on the outer surfaces 9 of the slots 2 adjacent corrugated leaf springs.



     - The production effort for the connection according to the invention is relatively low as far as the actual processing is concerned. The hub of the drive pulley is to be provided with a cylindrical bore, while the slots to accommodate the corrugated flat springs can already be cast with sufficient accuracy using the die-casting process. Any slight dimensional deviations that may exist are compensated for by the leaf springs. The driver surfaces 4 on the shaft 8 can at
Application of one or two surfaces can be easily milled or broached in one operation.



   The drive pulley with the flat springs accommodated therein under the required pretension can be applied to the shaft by means of a press-on device or, as in FIG
Shown in the drawing, with the aid of a hexagon screw 6 and a pressure washer 7, which can then remain on its seat to secure the connection.



   The illustrated embodiment of the invention is only an example of implementation thereof.



   The arrangement can also be made in such a way that only one slot or, in the case of a larger shaft diameter, several slots are provided for receiving the transmission springs, depending on the size of the torque to be transmitted.



   PATENT CLAIMS:
1. Connection between the shaft and the hub of a machine drive for the transmission of torques, in which the shaft has driver surfaces on its circumference that have been created by removing segment-like parts, against which transmission members rest that are supported in corresponding slots in the hub characterized in that the transmission members supported in the slots of the hub and resting on the driving surfaces of the shaft are corrugated leaf springs (3).
