ABSTRACT:
A sprocket of the type typically used for driving a plastic conveyor belt is split through the drive shaft hole at its center, so that the sprocket can be assembled over a drive shaft without disrupting the conveyor assembly. Two sections which form the drive shaft preferably are identical, and may be machined from high molecular weight polyethylene. In a preferred embodiment the two sections are assembled together by interlocking features shaped as jigsaw puzzle pieces. The two sections are placed against the drive shaft and are moved together in the axial direction of the drive shaft, thus sliding the sections together. One or more fasteners may be provided at easily accessed locations to permit the two sections from sliding apart.
