ABSTRACT:
A sprocket arrangement for driving conveyor belts is disclosed which provides improved operation in the presence of abrasives, corrosives and contaminants. The metal sprocket is used with modular plastic belts to produce long wear and improved performance. The sprocket is formed by aligning a multiplicity of thin substantially disk shaped metal sprocket lamina across the width of the belt. Groups of aligned lamina may be formed into a rigid sprocket unit by simply bolting or welding. Each of the sprocket lamina includes a non-circular central aperture for fitting onto a drive shaft. Driving surfaces are formed around the perimeter of each driving lamina. The lamina may be stacked in contact with each other, or for some applications may use spacers to separate selected ones of the stacked lamina so as to cooperate with the structure of the belt being driven.
