摘要
A blade-type chain tensioner includes a bracket that includes a main wall, a ramp projecting from the main wall, and a pivot pocket including an internal concave pivot surface. A tensioner blade assembly is operatively connected to the bracket. The tensioner blade assembly includes a polymeric shoe and a spring connected to the shoe. The shoe includes a free end supported on the ramp, a pivot end engaged with the pivot pocket, and a central body that extends between the free end and the pivot end. The pivot end of the shoe includes a pivot barrel including an external convex pivot surface. The pivot barrel is engaged with the pivot pocket and the external pivot surface of the pivot barrel is slidably abutted with the internal pivot surface of the pivot pocket such that the pivot barrel is reciprocally angularly movable in the pivot pocket.
