ABSTRACT:
A vibration proofing system for an engine timing chain utilizes a tensioner on the slack side of the chain path, in which a ring-shaped, chain-engaging shoe is rotatably disposed on a circular frame mounted on the piston of a tensioner mechanism, and in which the shoe surrounds the frame and tensioner mechanism. Engine oil, which is used in the tensioner, is supplied from the tensioner to lubricate the rotatable chain-engaging shoe. On the tension side of the chain path, a guide includes fixed support, a first ring rotatable on the support, and a ring-shaped, chain-engaging shoe which is in off-centered relationship to the support and the inner diameter of which is larger than the outer diameter of the first ring. Engine oil is supplied through the support to lubricate the first ring.
