Abstract
A power transmission chain-belt as disclosed is especially adaptable to transmit power between the pulleys of a pulley transmission, the pulleys of which are each constructed of a pair of flanges. The chain-belt comprises a plurality of sets of interleaved links joined by pivot means, and a set of at least three generally V-shaped or trapezoidal load blocks located between each adjacent pair of pivot means. Each load block has a central opening permitting its assembly with the links, and edge surfaces to drivingly contact the pulley flanges. The central opening of the load blocks has a height greater than the height of the links, so as to define a space therebetween. Resilient means, such as a curved leaf spring, is positioned between each set of links in the space between the chain and the central opening of a set of load blocks to apply a force on the load blocks of each set. The load blocks of a set engage the pulley flanges at different times, both insuring a sharing of the load by all blocks of a set of blocks and also changing the usual pattern of impact noise due to the blocks successively engaging the pulley flanges.
