ABSTRACT:
A chain-belt for engagement with the pulleys of a continuously variable transmission consists of interleaved sets of chain links joined for articulation by a joint which has a rocking action. The joint includes a pair of pins. A small camber is introduced into one or both of the pins to create a spring load between the pins and the links to retain the pins in the chain during handling and assembly. Each chain link includes a pair of spaced apertures adjacent the opposite ends; each aperture has a generally hour-glass shape with the enlarged ends receiving the pins. Also, each chain link has a pair of oppositely disposed tabs adjacent one end with the location of the tabs on the links alternating on adjacent links of each set. In addition the outermost two links of each set of links has a width substantially less than the width of the inner links in that same set.
