<p>Self contained modular powered sprocket drive units for modular link conveyor belt drive systems are disposable across the belt width to mate laminar sprocket ring drive teeth (16) into corresponding mating belt drive surfaces. These modular units may be located along the belt at one or more positions, and are easily removable for maintenance or replacement. A set of sprocket rings (20) are mountable axially in locations that match different belt drive requirements. Provision is made to fix one sprocket drive lamination (17) in place for belt tracking purposes with other sprocket drive laminations floating axially on the drive shaft for dynamic conformation to dimensional changes in the modular link belt (15) when driven. The drive shaft is hollow and contains an electric motor and gear drive train, thus permitting the modular drive unit to be no longer than the width of the driven belt. <IMAGE></p> |
