ABSTRACT:
A belt tensioner of the Zed type with a pivot-arm attached to an off-set cylindrical member supported by sleeve-type bushings with axially spaced-apart bearing surfaces disposed over a pivot where the bearing surfaces have an axial length that is sized for an average pressure contact. The tensioner may include a spring activated damping mechanism with a brake shoe having oppositely facing inside ramp surfaces which operate in such a manner to provide a normal force that is greater than a spring force applied to the brake shoe.
