Abstract
A spiral conveyor belt comprising a plurality of link assemblies adapted to be interconnected so as to permit coplanar rotational movement relative to one another. Each of the link assemblies having a plurality of forward link ends and a plurality of rearward link ends. A link shaft is disposed through the forward link ends and the rearward link ends of adjacent link assemblies for interconnecting the link assemblies to form the spiral conveyor belt. Each of the link shafts is tapered at least near the first end thereof to permit movement of the tapered portion of the link shaft in shaft openings in the forward and rearward link ends as the spiral conveyor belt is turned on a radius. In a second embodiment, the link shafts have a longitudinal axis, a straight surface for carrying the tensile load between adjacent link assemblies as the conveyor belt is traveling along a straight path, and a tapered surface for carrying the tensile load between adjacent link assemblies as the conveyor belt is traveling on the radius, the tapered surface disposed angularly about the longitudinal axis relative to the straight surface and the tapered surface intersecting the straight surface so as to form a transition zone along which the tensile load on the straight surface is rotatably transferred to the tapered surface when the conveyor belt changes from traveling along the straight path to traveling on the radius.
