ABSTRACT:
A tensioner for a power transmission belt that is adapted to be operated in an endless path and a method of making the same are provided, the tensioner comprising a support unit for being fixed relative to the belt, a belt engaging unit carried by the support unit and being movable relative thereto, a mechanical spring unit operatively associated with the support unit and the belt engaging unit for urging the belt engaging unit relative to the support unit and against the belt with a force to tension the belt, the mechanical spring unit providing the sole force of the tensioner for tensioning the belt, and a fluid dampening unit operatively associated with the support unit and the belt engaging unit to dampen the movement of the belt engaging unit relative to the support unit in at least one direction of movement thereof with a restricting force of the dampening unit. The dampening unit dampens the movement of the belt engaging unit with a greater restricting force when the belt engaging unit is being moved away from the belt than the restricting force of the dampening unit when the belt engaging unit is being moved toward the belt.
