Description

Bei dem vorliegenden Erfindungsgegenstand handelt es sich um ein Riemengetriebe, bei welchem die Umdrehungszahl stufenlos regelbar ist. Dies ist nun dadurch möglich, daß das Riemengetriebe zugleich als Reibgetriebe ausgebildet ist. Es können alle bekannten Riemenarten entsprechend Verwendung finden, und der Antrieb kann sowohl von der Riemenscheibenseite aus w;ie auch von der Reibungsscheibe aus beliebig erfolgen. In beiliegender Zeichnung ist das Getriebe durch 8 Abbildungen veranschaulicht.The present subject matter of the invention is a belt drive, at which the number of revolutions is infinitely variable. This is now possible by that the belt drive is also designed as a friction drive. Everyone can do it known types of belts are used accordingly, and the drive can both can be done from the pulley side as well as from the friction disk. In the accompanying drawing, the gear unit is illustrated by 8 figures.

Abb. i, a und 3 zeigen schematisch än Seitenansicht, Vorderansicht und im Grundriß ein Getriebe mit Flachriemen und flacher Reibungsscheibe, wogegen Abb. q. in Seitenansicht das gleiche Getriebe mit flacher Reibungsscheibe, jedoch statt mit Flachriemen mit Keilriemen zeigt. Durch Abb. 5, 6, 7 und 8 sind zwei Getriebe in Seiten- und Vorderansichtersichtlich gemacht,di'emitkonischerReibungsscheibe und mit Keilriemen arbeiten. Das Getriebe Abb. 5 bzw. Abl5. 6 untersche_det sich von dem Getriebe Abb. 7 bzw. 8 nur dadurch, daß statt nur einer zwei Anlauf- bzw. Reibflächen gegeben sind.Figs. I, a and 3 show schematically a side view, front view and in plan a transmission with a flat belt and a flat friction disc, on the other hand Fig.q. in side view the same gear with a flat friction disc, however instead of flat belts with V-belts. Through figs 5, 6, 7 and 8 are two gears made visible in side and front views, the conical friction disc and work with V-belts. The gearbox Fig. 5 or Abl5. 6 differs of the gearbox Fig. 7 or 8 only in that instead of just one two start-up or Friction surfaces are given.

Die stufenlose Regelung wird nun dadurch erzielt, daß der Riemen c durch die Preßscheibe bzw. -rolle b gegen die Reibungsscheibe a gepreßt wird und wie beim Reibungsgetriebe in bekannter Weise radial zumMittel oder zumAußendurchmesser entsprechend verschoben wird. Bei der Ausführung Abb. 5 und 6 muß der Riemen gleichmäßig gegen das Mittel oder gleichmäßig nach außen verschoben werden; damit die zwei Reibungsstellen gleiche Geschwindigkeiten ergeben. Bei der Ausführung Abb. 7 und 8 isst dies nicht nötig. Bei den Ausführungen entsprechend Abb. 5 bis 8 sind sogenannte Spannrollen g angebracht, außerdem Leitrollen, die mit d, e, f bezeichnet sind. Das Getriebe kann noch in verschiedenen ähnlichen Ausführungen gefertigt werden. Die Pressung zur nötigen Reibung kann von der Riemenseite aus wie auch von der Reibungsseite aus erfolgen. Sie kann durch Schwergewicht oder durch eine Federung o. dgl. erzeugt werden.The stepless control is now achieved in that the belt c is pressed against the friction disk a by the pressure disk or roller b and, as in the case of the friction gear, is shifted radially towards the center or towards the outer diameter in a known manner. In the case of Fig. 5 and 6, the belt must be shifted evenly against the center or evenly outwards; so that the two points of friction result in the same speeds. With the execution Fig. 7 and 8 this does not have to be eaten. In the designs according to Figs. 5 to 8, so-called tensioning rollers g are attached, as well as guide rollers, which are labeled d, e, f. The transmission can also be manufactured in various similar designs. The pressing for the necessary friction can take place from the belt side as well as from the friction side. It can be generated by heavy weight or by a suspension or the like.
