Rocker joint silent chain having a joint pin thicker than a corresponding rocker pin

摘要

In a silent chain, multiple link plates (2) are interleaved and connected to each other by connecting pins in a rocker joint (20). The rocker joint includes a joint pin (15) and a rocker pin (16) which are inserted into pin apertures (10). Guide links are placed on both ends of the joint pins. The joint pins (15) are slightly longer than the rocker pins (16). Each rocker pin (16) and joint pin (15) has a cross-sectional area. The cross-sectional area of the joint pin (15) is made larger than that of the rocker pin (16). In another embodiment, the rocker joint (20) has a joint pin (16) with a greater thickness than that of the rocker pin (16). Another embodiment of the invention includes a rocker joint where the radius of the curvature of the rolling surface of the joint pin (15) is greater than that of the rocker pin (16).
