Anordnung-der Fig. 3 der Riemscheibendurchmesser ungefähr dreimal so gross sein muss wie der des Zahnrades.
Greifen am schwenkbaren Teil ausser dem Riemenzug noch andere schwenkende Kräfte z. B.
Federn an, so ist bei der Ermittlung des Durchmesserverhältnisses im Sinne der oben stehenden Ausführungen nur der wirksame Teil der in die Schwenkrichtung fallenden Komponente des Riemenzuges zu berücksichtigen.
PATENT-ANSPRÜCHE :
1. Vorgelege mit Spannvorrichtung für Riementriebe 11. dgl., bei dem die Riemscheibe samt den mit ihr gleichachsigen Zahnrade in einem um die Achse des Gegenrades frei schwingbaren Lenker gelagert ist, dadurch gekennzeichnet, dass der Durchmesser der Riemscheibe (d) grösser ist als der einfache Durchmesser, aber kleiner als der sechsfache Durchmesser des mit ihr gleichachsigen Zahnrades (c).

Arrangement - of Fig. 3, the pulley diameter must be approximately three times as large as that of the gear.
Gripping the pivotable part in addition to the belt pull other pivoting forces z. B.
When the diameter ratio is determined in the sense of the above explanations, only the effective part of the component of the belt pull falling in the pivoting direction is to be taken into account.
PATENT CLAIMS:
1. Back gear with tensioning device for belt drives 11. The like, in which the pulley, together with the gear wheel coaxial with it, is mounted in a handlebar that can freely swing around the axis of the mating gear, characterized in that the diameter of the pulley (d) is greater than that single diameter, but smaller than six times the diameter of the gear wheel coaxial with it (c).
