ABSTRACT:
A sprocket and a module for forming a heavy duty, smooth top, straight running conveyor belt which is easy to clean and which uses a center transverse tooth member to receive a driving force from an intermeshed sprocket is disclosed. Each of the modules is suitable for being pivotally connected with a multiplicity of similar modules by pivot rods to construct a conveyor belt. Each of the modules includes first and second pluralities of link ends which are aligned in the module to form first and second pivot axes. Each of the link ends have a topmost portion which has a width which is just less than the space between two adjacent link ends on the same module, such that when intermeshed with link ends of another module a continuous, flush, smooth top surface is provided. The pluralities of link ends of each of the modules are joined by an integrally molded smooth top connecting structure which includes a tooth member extending downward and parallel to the pivot axis. The tooth member further defines driving surfaces on opposite sides for receiving a driving force from a drive recess of a cooperating sprocket to move the module and the belt constructed from a multiplicity of the modules. To achieve tracking, the bottom portion of each link end is substantially narrower than the topmost portion such that spaces are provided between the intermeshed link ends. A multiplicity of tracking teeth are also provided on the cooperating sprocket which are received by the space between the intermeshed link ends.
