KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Für bestimmte Handkurbelantriebe, insbesondere transportable Antriebe, ist es erwünscht, eine Handkurbel zu besitzen, welche rasch auf den Kurbelzapfen aufgesteckt und rasch wieder abgenommen werden kann, welche jedoch im aufgeschobenen Zustand sicher festsitzt, ohne durch irgendeine Lagenänderung des Mechanismus abfallen zu können. Die bisherigen Konstruktionen haben zu diesemFor certain hand crank drives, especially transportable drives, it is desirable to have a hand crank, which is quickly attached to the crank pin and can be quickly removed again, which, however, is securely stuck in the pushed-on state, without any change in position of the mechanism to be able to fall off. The previous designs have to do with this

ίο Zwecke Sicherungsstifte usw. vorgesehen, welche aber verlorengehen können. Durch den Verlust derartiger Teile können die ganzen Antriebe unbrauchbar werden.ίο purpose locking pins etc. provided which but can get lost. The loss of such parts can damage the entire drives become unusable.

Die vorliegende Erfindung erreicht den gedachten Zweck durch folgende Anordnung:The present invention achieves the intended purpose by the following arrangement:

Fig. ι stellt eine Handkurbel im Schnitt dar, deren Nabe so durchgefräst ist, daß zwei erhöhte Ansätze a, b stehenbleiben. Fig. 2 stellt die Handkurbel in der Ansicht dar.Fig. Ι shows a hand crank in section, the hub of which is milled through so that two raised approaches a, b remain. Fig. 2 shows the hand crank in the view.

ao Die Ansätze a, b bilden die Klauen einer Kupplung. In das zylindrische Loch der Kurbel wird eine Nut c eingedreht, in welche ein federnder Polygonsprengring so eingelegt ist, daß er nur schwer herausgenommen werden kann, von selbst aber, keinesfalls herausfällt. Fig. 3 stellt den Wellenzapfen dar, der einen Bund d trägt, an welchem zwei Flächen so angefräst sind, daß sie in die Aussparung der Kurbelnabe hineinpassen und sich an die Klauen a, b anlegen. Es ist somit Welle und Kurbel nach Art einer Klauenkupplung verbunden. In den zylindrischen Ansatz an der Welle ist ebenfalls eine Nut e eingedreht, welche bei aufgesteckter Kurbel der Nut in der Nabe genau gegenübersteht.ao The approaches a, b form the claws of a clutch. A groove c is screwed into the cylindrical hole of the crank, into which a resilient polygonal snap ring is inserted so that it can only be removed with difficulty, but does not fall out by itself. Fig. 3 shows the shaft journal which carries a collar d on which two surfaces are milled so that they fit into the recess of the crank hub and rest against the claws a, b . It is thus connected to the shaft and crank in the manner of a claw coupling. A groove e is also screwed into the cylindrical extension on the shaft, which is exactly opposite the groove in the hub when the crank is attached.

Wird die Kurbel auf den Wellenzapfen aufgeschoben, so schnappt der Polygonsprengring in die Eindrehung in dem Wellenzapfen ein und verhindert das Abfallen der Kurbel. Je nach der Tiefe und Form der Rinne kann man erreichen, daß die Kurbel loser oder fester sitzt und durch einen raschen Druck leichter oder schwerer abgezogen werden kann.If the crank is pushed onto the shaft journal, the polygon snap ring snaps into the recess in the shaft journal and prevents the crank from falling off. Depending on the depth and shape of the groove, the crank can be made loose or sits more firmly and is easier or more difficult to pull off with a quick push.

Claims (1)

Patent-Anspruch:Patent claim: Lösbare Kurbelnabe, dadurch gekennzeichnet, daß die Nabe, als Zahnkupplung ausgebildet, in eine entsprechende Gegenkupplung der Welle eingreift, und die achsiale Verschiebung durch einen in die Nabe eingebauten federnden Polygonsprengring, der in eine entsprechende Nut der Welle eingreift, verhindert wird.Detachable crank hub, characterized in that the hub is a tooth coupling formed, engages in a corresponding mating coupling of the shaft, and the axial Displacement by a resilient polygonal snap ring built into the hub, which is inserted into a corresponding groove in the shaft intervenes, is prevented.
