摘要： In an aspect, a tensioner is provided, comprising a base, a tensioner arm, a tensioner spring, a wheel, and a damping structure. The base is mountable to an engine. The tensioner arm is pivotally connected to the base for movement about a tensioner arm axis. The tensioner spring is connected between the base and the tensioner arm and is positioned to urge the tensioner arm towards a free arm position. The wheel is rotatably mounted to the tensioner arm and is engageable with an endless drive member. A friction surface is provided on one of the base and the tensioner arm. The damping structure is provided on the other of the base and the tensioner arm and engages the friction surface to generate friction during rotation of the tensioner arm. The damping structure includes a sleeve that contains at least one aperture and a damping element that contains at least one lug that engages the at least one aperture with no circumferential clearance therebetween.
