ABSTRACT:
A tensioner for belts including a stationary structure (3), an arm (4) movable with respect to a shaft (7) of the stationary structure, a torsion spring (6), a pair of dampening cones (8), (9) associated with the stationary structure and the arm, a compression spring (10) acting on the dampening cones. The mean radius of the cones is smaller than the maximum radial dimension of the torsion spring. The value "1" of the arm is correlated to the mean radius of the cones determining a frictional dampening between the cones smaller than that existing between the shaft and the rotating arm.
