Abstract
A chain assembly has pins extending through the guide links with minimal projection beyond the outside edge of the guide links. The minimal pin projection provides a chain assembly of narrow construction. Modular chain systems are also provided that permit manufacturing savings in the construction of chain systems of standard widths.
Claims2
A silent chain and sprocket assembly, comprising:
- first and second chains, each of said chains having a plurality of interleaved sets of links, said chains being in side-by-side relationship around sets of sprockets, each chain having an inner portion that is located closest to the other chain and an outer portion located on the opposite side of said chain from said inner portion,
- each chain having pivot members connecting adjacent sets of links, each link having a pair of apertures for receiving said pivot members,
- each chain having some of said sets of links including inside links, each of said inside links having at least one depending tooth adapted to contact the teeth of a sprocket, said inside links being constructed to permit articulation of said inside links with respect to said pivot members,
- each of said chains having some of said sets of links with at least one guide link at said inner portion of said chain and an outer link at an outer portion of said chain, said guide links having said pivot members extending through at least a portion of said apertures of said guide links,
- said first chain being of a first width extending from said first chain inner portion to said first chain outer portion, said second chain assembly being of a second width extending from said second chain inner portion to said second chain outer portion,
