ABSTRACT:
A frictional transmission chain, comprising: an endless transmission chain formed from link plates and link plate connection pins; a plurality of frictional V blocks, each having a hollow interior through which a portion of the endless transmission chain extends, each having inner lateral surfaces with holes therein for receiving opposite ends of at least one of the connection pins, and each having inclined, generally trapezoidal outer lateral surfaces; and, frictional transmission contact surfaces of a generally V-shaped configuration, transversely symmetrical about a centrally disposed recessed portion, and projecting radially from the outer inclined lateral surfaces with respect to a V-groove pulley with which the transmission chain is adapted to tightly frictionally engage by means of the V blocks, power being transmitted along the chain only by the link plates and connection pins of the endless chain, each of the V blocks transmitting power only between its respective at least one connection pin and the pulley.
