Belt design

A flat belt operates on pulleys of diameters 125 and 375 mm. The smaller pulley operates at 1500 rpm. The centre distance of the pulleys is 1525 mm. The flat belt has a weight of 5.4 N/m.

Determine the linear belt speed.

Determine the belt tension ratio for a coefficient of friction of 0.3 and an angle of wrap of 170.6° on the smaller pulley.

Determine the power that can be transmitted with a belt pre-tension = 1 kN.
