Abstract: A new asymmetrically damped tensioner is provided utilizing a roller clutch engaged with a tensioner arm through a frictional contact. During normal operation, the roller clutch enables the tensioner arm to pivot in a first direction to take up belt slack with negligible frictional damping applied to the motion of the tensioner arm. When the tensioner arm pivots in a second direction, away from the belt, however, in a condition commonly known as wind-up, the roller clutch engages and creates a frictional linkage between the tensioner arm and a fixed surface. This frictional linkage provides asymmetric frictional damping to the tensioner to limit movement in the second direction and combat wind-up.
