Friction type one-way high damping gauge tensioner
A tensioner for reducing vibration and noise associated with a vehicle engine includes: a tensioner arm having a cylindrical protrusion extending from a first side of the tensioner arm; the cylindrical protrusion having at least one counter-bore disposed on a surface of the cylindrical protrusion and an inner bore extending through the cylindrical protrusion; an axle adapted to be received by the inner bore, the tensioner arm being adapted to rotate about the axle; a spring disposed proximate a second side of the tensioner arm, opposite the first side, the spring being adapted to bias the tensioner arm in a first direction; and a damping structure that includes a gripping seat adapted to engage a portion of the tensioner arm, in which the damping structure limits rotation of the tensioner arm in a second direction opposite the first direction.
