Abstract

A stack of gears including and a first and a second gear disposed in parallel relation to, and sharing a common axis with, the first gear. Each gear is of a different diameter and each includes a plurality of teeth. At least one transition train is teeth disposed between the first gear and the second gear. Like the first and second gear, the transition train also includes a plurality of teeth that are disposed in substantially perpendicular relation to the common axis. The transition train is dimensioned to form at least one deceleration channel and at least one acceleration channel extending from each of the first gear and the second gear. The stack of gears may be dimensioned for use with a pinion gear, or with a continuous loop drive, such as a chain or belt.
