Abstract
A short pitch tooth chain that reduces the level of impact noise generated during operation is disclosed. A chain system includes a first sprocket having a plurality of sprocket teeth spaced apart by a first distance, a second sprocket also having a plurality of sprocket teeth spaced apart by the first distance, and a short pitch tooth chain wrapped around the first and second sprockets. The short pitch tooth chain includes a first link having a first aperture spaced from a second aperture by a second distance, a second link having a first toe spaced from a second toe by the first distance, the second link having a third aperture and being connected to the first link by a first pin extending through the first and third apertures, and a third link having a third toe spaced from a fourth toe by the first distance, the third link having a fourth aperture and being connected to the first link by a second pin extending through the second and fourth apertures. The first distance defines a sprocket chordal pitch and the second distance defines a chain pitch wherein the chain pitch is about twice the sprocket chordal pitch.
