A belt tensioner for a power transmission belt system includes: (a) a base housing (16) having a pivot shaft (38) extending therefrom; (b) a tension arm (14) pivotally mounted on the pivot shaft (38) at a proximal end (42) thereof, the proximal end of the tension arm (14) including a rub surface (84) and the distal end (20) of the tension arm adapted to contact a power transmission belt (12); (c) a torsion spring (18) operatively coupled between the base housing (16) and the tension arm (14) and adapted to bias the distal end (20) of the tension arm against the power transmission belt (12); and (d) a damper assembly (76) coupled to the housing (16), the damper assembly including: (1) a body (80) of friction material that includes a friction surface (86) adjacent to and facing the rub surface (84) of the tension arm (14) and (2) a damper spring (78) integral with the body (80) of friction material and biasing the body of friction material and associated friction surface (86) against the rub surface (84) of the tension arm (14).
Dispositif de tension conçu pour une courroie de transmission et comprenant : a) un boîtier de base (16) possédant un arbre de pivot (38) s'étendant depuis ledit boîtier ; b) un bras de tension (14) monté pivotant sur une extrémité proximale (42) du bras de pivot (38), l'extrémité proximale du bras de tension (14) présentant une surface de frottement (84) et l'extrémité distale (20) de ce bras de tension étant conçue pour venir en contact avec une courroie de transmission de puissance (12) ; c) un ressort de torsion (18) accouplé entre le boîtier de base (16) et le bras de tension (14) et conçu pour solliciter l'extrémité distale (20) de ce bras de tension contre la courroie de transmission (12) ; d) un ensemble amortisseur (76) accouplé au boîtier (16) et comprenant : 1) un corps (80) en matériau de friction comportant une surface de friction (86) contiguë à la surface de frottement (84) du bras de tension (14) et placé en face de ladite surface (84), et 2) un ressort d'amortissement (78) solidaire dudit corps et sollicitant celui-ci, ainsi que la surface de friction associée (86), contre la surface de frottement (84) du bras de tension (14).
