Abstract
A chain tensioner includes a blade assembly operatively connected to a bracket. The blade assembly includes a plastic blade and a spring, with a first spring end located in a first slot and a second spring end located in a second slot. The first spring end contacts a first lower wall at a first contact location and the second spring end contacts a second lower wall at a second contact location. A pivot end spring force vector SFP acts on the first lower wall at the first contact location and a free end spring force vector SFR acts on the second lower wall at the second contact location. A chain is in contact with the outer surface of the blade. The blade assembly is mounted on the bracket with a bracket pin located in the pivot bore and with the foot of the blade supported on a bracket ramp. A pivot pin force vector FP acts on an inside diameter of the pivot bore through the pivot axis. A ramp force vector FR acts on the blade foot at a ramp contact location. The ramp force vector FR and the free end spring force vector SFR are aligned and coincident with each other.
