ABSTRACT:
A conveyor drive sprocket system for driving a conveyor belt in a conveyor system used in varying ambient temperature conditions within a predetermined range is disclosed. The conveyor belt is formed of a material having a coefficient of thermal expansion different from that of the material forming the sprockets of the drive sprocket system so that the drive sprockets expand and contract at a different rate than the conveyor belt when the ambient temperature varies. The drive sprocket system includes a plurality of sprocket segments spaced from one another along the width of the conveyor belt. Each sprocket segment has a plurality of spaced teeth arranged along the width and circumference of the segment in order to mesh the conveyor belt. Each sprocket segment has a width no greater than that required to have the teeth remain in mesh with the conveyor belt throughout the predetermined range of varying ambient temperature. The sprockets are spaced from one another a sufficient degree so that the sprocket segments do not thrust laterally against one another throughout the predetermined range of varying ambient temperature.
