ABSTRACT:
A method for tensioning a synchronous toothed belt with the tensioner so as to substantially inhibit movements of the pivot arm as attributed to dynamic tension variations in a belt drive system while damping movements of the arm. A method for tensioning a synchronous belt drive with the tensioner by biasing a moveable pulley against the belt with a force sufficient to limit the amplitudes of resonance tension variations and damping the biasing of the pulley to prevent substantially most cyclic movements of the pivot arm while simultaneously accommodating thermal changes in drive length.
