<p>CHAIN-BELT A metal chain-belt (31) especially usable to drivingly connect the pulleys of a pulley transmission, and constructed of a carrier which may comprise a plurality of sets of links (35,37) interleaved with those of adjacent sets, with the sets being joined by pivot means (41). Drive blocks (43) encircle the carrier. The blocks each have side edges adapted to drivingly engage the flanges of the pulleys. These side edges are crowned to improve the life and performance of the chain-belt assembly. The radius of curvature of the crowned side edges is far in excess of the width of a drive block.</p> |
