Abstract
A roller chain assembly has pins extending through the outer links with minimal projection beyond the outside edge of the outer links. The minimal pin projection provides a chain assembly of narrow construction.
Claims16
A roller chain assembly, comprising:
- a series of interleaved inner and outer links, each outer link having a pair of outer link plates fixedly mounted to spaced pin members, each outer link plate having a pair of apertures for receiving said pin members;
- each inner link having a pair of bushings mounted to turn on said pin members of said outer links, said inner links having inner link plates fixedly mounted to said bushings, each inner link plate having a pair of apertures for receiving said bushings;
- each of said inner links and said outer links being adapted to receive a sprocket tooth;
- said outer links having said pin members extending through at least a portion of said apertures of said outer link plates, said pin member extending from beyond an edge of a first outer link plate member to beyond an edge of a second outer link in said pair of outer link plates,
- said pin member extending a greater distance beyond said edge of said first outer link plate than the distance said pin member extends beyond said edge of said second outer link plate.

2 more elements
A roller chain and sprocket assembly, comprising:
- first and second roller 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 pin members connecting adjacent sets of links, each link having a pair of apertures for receiving said pin members,
- each chain having some of said sets of links including rollers, each of said rollers being adapted to contact the teeth of a sprocket, the location of the rollers of said first chain being offset with respect to the rollers of said second chain,
- each of said chains having sets of outer links and inner links, said sets of outer links having a first outer link plate at said inner portion of said chain and a second outer link plate at an outer portion of said chain, said outer links having said pin members extending through at least a portion of said apertures of said outer link plates, said pin members extending from beyond an edge of said first outer link plate to beyond an edge of said second outer link plate in said sets of outer links,
- at least some of said pin members of said first chain contacting at least some of said first outer link plates of said second chain as said chains transverse said sprockets during operation.
