Abstract

A tensioner comprising a sleeve, an adjuster cooperatively engaged with an inner surface of the sleeve, a pivot arm pivotally engaged with the sleeve, a pulley journalled to the pivot arm, a torsion spring engaged with the sleeve for urging the pivot arm, an elastomeric damping ring connected to the arm and in compressive frictional contact between the sleeve and the arm whereby a tangential friction force damps a pivot arm movement, the elastomeric damping ring exerting a radial force on the sleeve, and a retaining member connected to the adjuster and cooperatively engaged with the sleeve whereby the adjuster and sleeve are kept in a predetermined relation.
