Dodge conveyor pulleys: life comparison

T = belt tension (/ the total tension given in Tables ) R = outside radius of pulley rim W = belt width We applied the belt load over a shorter area than the typical belt load due to meshing considerations (see Figure !). This causes the belt force to be applied over a smaller surface area, thus the pressure loading is a little on the high side.
