  • Floating flexible drive element tensioner
    Patent number: 6117034
    Abstract: A floating chain tensioner includes a pair of opposing sprockets with at least one sprocket in slidable relation relative to the other. A pair of elastomer tensioning bands urges the slide-mounted sprocket towards the other sprocket. The floating chain tensioner captures a drive chain between the sprockets to establish tension therein. The tensioning sprockets enjoy some freedom of movement relative to one another while maintaining tension against the drive chain during operation of an associated chain-driven mechanism.
