Positively Infinitely Variable (PIV) chain drives are distinctive in the chain positively interlocks With all the conical pulleys. This is realized by using a stack of numerous modest rectangular plates in Each and every chain link which will slide independently from side-to-facet. The plates could be pretty thin, all over a millimeter thick. The conical pulleys have radial grooves. A groove on a single facet in the pulley is achieved using a ridge on one other aspect and And so the sliding plates are pushed back and forth to conform to your sample, effectively forming tooth of the proper pitch when squeezed among the pulleys.
