ABSTRACT:
An endless driven sprocket chain (10) includes inner links (24) which couple to outer links (26) through a resilient bushing (50). A pin (42) having a shaft (44) with a hexagonal cross sectional shape mates with a corresponding hole in outer link plates (32, 34). The shaft (44) also mates with a hexagonal cross sectional shaped hole in the bushing (50) through an metallic insert (56). The bushing is pressed into a metallic sleeve (58) which in turn is press fit into inner link plates (28, 30) at holes (36) therein. The hexagonal alignment of the holes (40) in the outer link plates (32, 34) with the corresponding hole (54) in bushing 50 defines a resting position where the inner links (24) reside at an oblique angle to the outer links (26). When the inner links (24) form a substantially straight line with the outer links (26) the bushing is deformed and imposes a force of the links (24, 26) that urges the links (24, 26) toward the resting position.
