ABSTRACT:
A sprocket arrangement which provides increased contact surface area for driving conveyor belts is disclosed. The sprocket is particularly suitable for abrasive applications and/or use with modular plastic belts. The sprocket is formed by stacking and aligning a multiplicity of thin substantially disk shaped sprocket lamina together and then joining the stacked and aligned lamina by simply bolting or welding. Each of the sprocket lamina includes a central aperture for fitting onto a drive shaft. Teeth or other driving surfaces are also formed around the perimeter of each of the lamina. The lamina may be stacked in contact with each other, or for some applications may use spaces to separate selected ones of the stacked lamina so as to cooperate with the structure of the belt being driven.
