Abstract
A sprocket and drive shaft assembly for a wide conveyor belt composed of modules pivotally connected in chain-like fashion and subject to environmentally caused fluctuations in width such as extreme temperatures. The assemlby includes a drive shaft with a polygonal cross section and a plurality of toothed sprockets each having an axial bore which slidingly engages the cross section of the shaft and permits the sprockets to move laterally in response to fluctuations in conveyor width and lateral alignment, as the rotating sprocket assembly drives the conveyor. Restraining devices such as set screws are provided on the drive shaft to prevent the sprockets from undergoing excessive axial movement (toward the ends of the drive shaft) while allowing the sprockets axial freedom to shift in response to lateral belt misalignment and width fluctuation.
