Abstract
A speed reduction drive is comprised of a chain carrying a plurality of rollers, the chain being operatively connected to an output shaft via a sprocket or the like. The rollers of the chain progressively pass between a rotating drive pinion and a stator surface whereby the chain is driven at a linear speed which is a function of the diameter of the drive pinion and the arcuate surface of the stator, the speed of the chain being reduced by differential drive effects.
