ABSTRACT:
Sprocket drive mechanisms formed of metal lamina engage belt drive surfaces formed in a modular plastic conveyor belt. The lamina are positioned axially along a rotary drive shaft to mate with drive surfaces extending across the width of the belt. Belt wear from the metal sprocket lamina is reduced by floating at least one lamina axially along the drive shaft to conform with belt positioning under loading and other dynamic conditions. Spacers for axially separating the lamina for registration with belt drive surfaces when mounting the belt on the sprocket drive may be removed after registration, thereby keeping the metal drive assembly lighter with less inertia to further reduce wear. Alternatively light weight laminar spacers disposed axially along the shaft are interlocked to the sprocket lamina to maintain a fixed spacing while permitting the assembly and/or separate sprocket lamina to float axially on the shaft.
