Abstract

The invention comprises a tensioner having a linear motion. A pulley is journaled to a housing. A bearing is used to slidingly join the housing and a base. The bearing constrains the housing, and therefore the pulley, to move along a predetermined path. The housing also comprises an arcuate damping surface that interacts with a frictional or damping band. A torsion spring concentrically engages the frictional material band, pressing it in to engagement with the arcuate damping surface as the housing moves in response to an impulse or force from the pulley. As a belt load impulse causes the housing to move along the predetermined path, a contact between the damping band and the base causes the spring to further press the frictional damping material against the housing arcuate surface, thereby damping movement of the housing. Further, an axis of the pulley is offset from a centerline of the bearing. As the housing moves, a couple is created between the housing and the base acting through the bearing. The forces of the couple create a frictional force between the bearing surfaces, further damping a movement of the housing and thereby a movement of the pulley.
