Description

Riemscheibenwechselgetriebe mit Riemscheibe und Kegeltrommel. Die Erfindung betrifft ein Riemscheibenwechselgetriebe. Sie bezweckt, die sonst bei derartigen aus Riemscheibe und Kegeltrommelbestehenden Riemscheibenwechselgetrieben erforderliche Spannrolle entbehrlich zu machen. Dies wird dadurch ermöglicht, daß. die ,äußere Begrenzungslinie der Kegeltrommel annähernd kreisförmig gestaltet ist und infolgedessen die Geschwindigkeitsänderung nicht durch eine seitliche Bewegung des ganzen Riemens, sondern durch Verschwenken des einen auf der Trommel aufliegenden Riementrums hervorgerufen wird, wobei die Spannung des Riemens annähernd dieselbe bleibt. Das neue Getriebe ist in der Zeichnung veranschaulicht, und zwar zeigen die Abb. ia und ib das Getriebe im Grundriß und in der Seitenansicht, wogegen die Abb. a eine andere Ausführungsform desselben darstellt, bei welcher der endlose Riemen von der Kegeltrommel b über eine Führungsrolle j nach einer zweiten Kegeltrommele und zurück geführt ist. Bei der Ausführungsform des Getriebes nach Abb. ia und ib läuft der Riemen auf einer Riemscheibe a, deren Achse senkrecht zur Achse der Trommel b steht (halbgeschränkter Riemen). Die Verschiebung des Riemens zwischen den Punkten c und d der Kegel trommel b wird durch eine geeignete Leitvorrichtung bewirkt, die in der Zeichnung nicht dargestellt ist. Statt eines Riemens kann mit derselben Wirkung auch ein Band oder Seil oder eine entsprechend geformte Kette verwendet werden.Pulley change gear with belt pulley and cone drum. the The invention relates to a pulley change transmission. She aims to do that otherwise Such change-pulley transmissions consisting of pulley and conical drum to make the necessary tensioning pulley dispensable. This is made possible in that. the outer boundary line of the tapered drum is approximately circular and consequently the change in speed is not caused by a lateral movement of the entire belt, but by pivoting the one resting on the drum Belt runs caused, the tension of the belt being approximately the same remain. The new transmission is illustrated in the drawing, namely show the Fig. ia and ib the gear in plan and in the side view, while the Fig. A shows another embodiment of the same in which the endless Belt from the cone drum b over a guide roller j to a second cone drum and is led back. In the embodiment of the transmission according to Fig. Ia and ib the belt runs on a pulley a, the axis of which is perpendicular to the axis of the drum b stands (half-turned strap). The displacement of the belt between points c and d of the cone drum b is effected by a suitable guide device, the is not shown in the drawing. Instead of a belt can have the same effect a ribbon or rope or an appropriately shaped chain can also be used.
