Abstract
A phased chain and sprocket assembly is provided in which the pitch length of the chain is not matched to the pitch length of the sprocket. Specifically, the chain link pitch length is approximately twice the pitch length of the associated sprocket teeth. By providing two chains in side-by-side, but offset relation, a phased chain and sprocket assembly can be achieved without the need for circumferentially offset sprockets.
Claims3
A chain assembly, comprising:
- a plurality of interleaved rows of flat, plain inverted tooth links, pivot pins connecting adjacent rows of links, each link including a pair of apertures for receiving said pivot pins, each of said interleaved rows including at least three flat, plain inverted tooth links therein,
- each of said links including a flat planar main body portion and a pair of flat planar toes depending from said main body portion, said toes defining a first length extending from the bottom-most portion of said toes to the top of said link main body portion, said apertures defining a second length extending between the center points of each of said apertures,
- said second length being greater than said first length for each of said links.
