ABSTRACT:
A sprocket tooth modular link conveyor belt drive mechanism is provided for use in chemical and food environments where it is important to control contaminants and bacteria. Thus an easy to clean and sanitize modular assembly devoid of dirt and grime catching structure in the vicinity of the conveyor belt is provided. A further feature is the safety of operation, by encompassing moving belt drive equipment in a closed modular compartment shielded from the possibility of accidental damage to conveyor loads, or serivce and operating personnel. These improvements are achieved in a belt drive mechanism module with an enclosed hermetically sealed drive system operable from an internally disposed electric drive motor with associated drive gear train. An external rotatable hollow drum member carries the sprocket teeth and has a smooth outside easy to clean surface without a propensity to accumulate dirt or grime or leak lubricating oil, or to present operating hazards to operators and service personnel. Further significant advantages are presented in assembling a variety of sprocket tooth drive configurations which can accommodate lateral dynamic belt movements in operation and different sprocket tooth configurations matching various belt module configurations.
