Abstract:
1. A silent chain and sprocket assembly comprising: a sprocket having a plurality of low profile protrusions extending outwardly from said sprocket at locations spaced along an outer periphery of the sprocket; a silent chain having a series of inner link rows lying along a chain direction and a series of outer link rows, an outer link row between adjacent inner link rows and interleaved at opposite ends of the outer link row along the chain direction with the adjacent inner link rows; adjacent inner and outer link rows are joined to each other by members extending through interleaved portions of adjacent inner and outer link rows to form a rotatable joint between the adjacent inner and outer link rows; the links of said inner and outer link rows form a surface that extends along the chain direction of the links a distance that approximates the distance from a center of a member joining the link to one adjacent row of links to a center of a member joining the link to another adjacent row of links, overlies the sprocket protrusions and contacts said low profile protrusions along at least the majority of the length of the surface for driving contact with the low profile protrusions; and the link surface extending along the chain direction a distance substantially the length of the link along the chain direction.
