1. Elastische Spannvorrichtung zur durch mechanischen Kraftschluß bewirkten Kraftübertragung mittels eines flexiblen Riemens, der eine antreibende Riemenscheibe (1) mit mindestens zwei angetriebenen Riemenscheiben (3) und (4) auf parallelen Achsen verbindet und mittels eines elastischen Drehmomentes eines Tragarms einer Spannrolle (5) betätigt ist, der sich durch seine einfache Verformung um einen das besagte Moment erzeugenden elastischen Ring (12) dreht, dadurch gekennzeichnet, daß die gleiche Drehachse (7) unter Zwischenschaltung des besagten elastischen Rings (12) als Wellenlager für eine in bezug auf die Achsen der angetriebenen Riemenscheiben ortsfeste zweite Umlenkrolle (8) dient, welche es dem flexiblen Riemen (2) der Kraftübertragung ermöglicht, jede der besagten angetriebenen Riemenscheiben (3) und (4) mit einem Winkel von mehr als 180° zu umschlingen, wodurch bei gleichen Kraftübertragungsbedürfnissen eine viel schwächere Spannung möglich ist.
2. Elastische Spannvorrichtung zur durch mechanischen Kraftschluß bewirkten Kraftübertragung mittels eines flexiblen
Riemens nach Anspruch 1, dadurch gekennzeichnet, daß eine Voreinstellung im Werk durch Blockieren des elastischen Drehmoments des Tragarmes der Spannrolle (5) mittels einer Schraube (19),(19') ausgeführt ist, die nach dem Zusammenbau der Kraftübertragung freigegeben wird.
