Abstract
A tensioner including a support structure defining a pivot axis, an arm coupled to the support structure for rotation about the pivot axis, and a damping mechanism. The arm includes a cup having the damping mechanism seated therein. The damping mechanism includes a first tensioner component that is generally cup-shaped and has first ramp features on the rim thereof, a second tensioner component having second ramp features, and a damper spring coupling the first tensioner component to the second tensioner component. The first tensioner component is rotatable with the arm and the second tensioner component is non-rotatable. The damper mechanism has the first ramp features aligned with the second ramp features and rotation of the first tensioner component in a first direction moves the first ramp features relative to the second ramp features and translates the first tensioner component into damping engagement with the arm.
