Abstract
A tensioner having a base. A spring connected to the base biases a plate, having a pulley, toward a belt. Frictional blocks are aligned on the base in a staggered fashion along a spring centerline. The plate slidingly moves in a linear path between the blocks. The blocks constrain the path of the plate allowing movement in only a single axis parallel to a spring axis. A hubload from a belt running on the pulley combined with the spring force acting on the plate creates a force couple acting on the plate through the frictional blocks. The engaging surfaces between the plate and the blocks have a predetermined coefficient of friction thereby creating a damping force as the pulley and plate move in a linear path on the blocks.
