Abstract
In a rocker pin type friction transmission chain, the engaged surfaces of the rocker pins and pin insertion holes in the link plates are in the form of parts of an ellipse which are symmetrical with respect to the minor axis of the ellipse. This configuration is easy to machine, prevents relative rotation of the pins and the link plates, avoids cracking of the link plates due to concentrations of loads, and reduces the likelihood of fatigue failure due to excessive pressures exerted by the pins and link plates on each other.
