ABSTRACT:
In a modular belt modular drive unit that can be independently mounted along a modular link belt system, a drive shaft comprises a drum having an integral outer circumferential surface with one or more axially oriented keying surface indentations for mounting mating sprocket wheels for moving axially along the shaft in response to dynamic conditions encountered in driving the belt. The belt is tracked in a preferred position along the shaft by means of a tracking sprocket wheel that has a confined degree of axial movement. Thus a circumferential indentation slot on the shaft surface receives the tracking sprocket wheel rotationally on the shaft so that it de-registers with the keying surface and is held axially in the slot. To use the tracking sprocket wheel as a drive wheel rotating with the shaft when disposed in the slot, the tracking wheel is linked to another sprocket wheel in a position axially confined in the slot.
