3. Global dynamics

3.1 Speeds, torques, inertia

Drive pulley rotation speeds are generally given and, from the pulleys' pitch radii, it's easy to determine the rotation speed of each pulley, assuming that the belt doesn't slip on the pulleys. The specifications specify the power absorbed by the driven machines (compressor, pump, alternator, etc.). It is necessary to calculate the resisting torques C _i (i = 2 to n) on the driven pulleys and also the driving torque to be provided by the driving pulley C ₁ . The following...
