WebExample 7.5. A flat belt is required to transmit 22 kW from a 250-mm diameter pulley running at 1450 rpm to a 355-mm diameter pulley.The coefficient of friction can be taken as 0.7, the density of the belt is 1100 kg/m 3, and the maximum permissible stress is 7 MPa. The distance between the shaft centers is 1.8 m.The proposed belt is 3.5 mm thick. WebAug 16, 2024 · Pulley calculations: pulley RPM and diameter calcualtions. We begin our analysis of the belt and pulley calculator with quantities independent from the belt. The diameters and rotations per minute of two pulleys connected by a belt are related by a simple formula: n_1\cdot d_1 = n_2\cdot d_2 n1 ⋅ d1 = n2 ⋅ d2.
