The chain sprocket 2 with diameter 300 mm istaken a power of 22,000 Watts from a driving gear motor at 250 rpm.The applied force of a chain onto –Z direction with thechain tension Fm1/Fm2 = 10(If Fm2 generated from a chain tensioner during operation). Anotherside of the shaftconnected with the chain sprocket 1which has a diameter 200 mm and consuming power about 30%for driving a screw conveyor. The tension force of Fc1/Fc2 = 10 (If Fc2 generated from a chain tensioner during operation also), but the total force direction aligns with 30fromX direction.The conveyor roller with diameter 275 mm and consuming the power about 60% for rotatesaconveyorbelt (the rest of power lost for some friction).The direction of a distributed tension load from conveyor belt (Fb) aligns onto X direction. The distributed weight (Fw) during operates material handling is about 50% of Fb.For a simplicity calculation, we assume that the conveyor roller is a rigid body. The distributed load Fw along the length of conveyor rollercan be combined to be Fw,tot and then equally divided on to the left and right hubs of conveyor roller such as Fw,1 and Fw,2 point load at those pointsR1 and R2, respectively.For the distributed load Fb can be done such as the same way.If define the length of a=100 mm, b=200 mm, c=700 mm, d=250 mm, e= 150 mm
