ABSTRACT:
A power transmission (10) chain-belt (32) is disclosed that is especially adaptable for connecting the pulleys (12, 14) of a pulley transmission (10). The chain-belt (32) has a plurality of interleaved sets (34) of links (36) and each set (34) has a plurality of transversely arranged links (36). Pivot members (40) join adjacent sets (34) of links (36) to form an endless loop. At least one toe (42A, 42B) extends from each link (36) in at least some sets (34) of links (36). At least the toes (42A, 42B) on adjacent links (36) are in opposed relationship and define a passageway 80. A plurality of load blocks (50) are connected to the links (36). The load blocks (50) are positioned in the passageway (80) defined by the toes (42A, 42B). Each load block (50) has edge surfaces (88) for contacting the pulleys (12, 14) of the transmission (10).
