A Review on Design of Live Roller Conveyor System

Gravity conveyors are design without considering the torsional effect on the roller shell. As the application changes the design of the roller may vary in terms of shaft, hub and shell assembly. In most of the research papers, crucial parts of roller conveyors like Roller, chassis and columns and bearings were targeted for weight optimization.

Determine the overall diameter of the roller plus the thickness of the belt. For example, if the conveyor belt you are using is 1/2-inch thick, the overall diameter is the core diameter, 8 inches, plus twice the thickness of the belt, 1 inch, for a total of 9 inches. Multiply the overall diameter by itself. In the example 9 times 9 is 81.
