Abstract:
A belt tensioner for a power transmission belt system, comprising:a base housing including a pivot shaft extending therefrom: a tension arm pivotally mounted on the pivot shaft at a proximal end of the tension arm, the proximal end of the tension arm including a rub surface and the distal end of the tension arm adapted to contact a power transmission belt; a torsion spring operatively coupled between the base and the distal end of the tension arm, adapted to bias the distal end of the tension arm against the power transmission belt; and a damper assembly adjacent to the proximal end of the tension arm, the damper assembly including a body of friction material including a friction surface adjacent to and facing the rub surface of the tension arm and a damper spring on which the body of friction material is integrally formed for biasing the body of friction material and associated friction surface against the rub surface of the tension arm.
