Abstract
A tensioner for a power transmission belt and a method of making same are provided. The tensioner includes an arm that carries a belt engaging unit and is adapted to be pivotably mounted to a support unit. A mechanical first spring is operatively associated with the support unit and the arm for urging the arm, and hence the belt engaging unit, relative to the support unit and against the belt for tensioning same. A fluidic dampener is operatively associated with the support unit and the arm to dampen movement of the arm relative to the support unit. The dampener comprises a first plate fixed to the support unit, a second plate fixed to the arm for rotation therewith and relative to the first plate, a second spring urging the first and second plates against one another, friction material disposed between part of the facing surfaces of the first and second plates, and fluid disposed between the facing surfaces of the first and second plates.
