a) C a l c u l a te t h e t o r q u e t o b e transmitted, considering service factor SF (see fig.4)and torque factor KD, following the formula on the right;
b) Confirm the preliminary election by cross checking the diameter of the shafts to be fitted onto the hubs;
c) Check that max speed n has to be equal or lower than the selected size coupling max speed multiplied by the speed fac tor KV, depending on operating misalignment α, shown on
fig.3;
