Abstract
A split sprocket for belts or chains comprising a first section and a second section that mates with the first section to form a sprocket with drive teeth distributed about the periphery and a central hub for retaining a shaft. The first section includes a snap clamp having a barbed tip for mounting the first section to a shaft. The second section includes mating elements complementary to mating elements in the first section to allow the second section to mate with the first section to form a complete sprocket.
