Abstract
A power transmission (10) chain-belt (32) is disclosed that is especially aptable for connecting the pulleys (12, 14) of a pulley transmission (10). The chain-belt (32) has a plurality of interleaved sets (34) of links (36and each set (34) has a plurality of transversely arranged links (36). Pivot means (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. At least the toes (42A, 42) 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 connecting the pulleys (12, 14 ) of the transmission (10). A notch (90) is positioned on each side of the load blocks (50) on the surface of the load blocks (50) that is adjacent the links (36). A retaining link (92) is positioned on each side of the sets (34) of links (36). The retaining links (92) engage the notches (90) and restrain the retaining links (92) from transverse movement and assist in holding the sets (34) of links (36) together.
