Drive and driven pulleys with multiple or single belts should be in the same line of action or in the same plane. If not in the same plane through cocking of one sheave relative to the other, or if parallel but not in alignment, then excessive vibration results.
Sometimes the length and tension on a drive belt results in a resonance within the belt whereby it acts like a resonant string.
Although relatively rare, a poorly made belt can within itself be out of balance. This results in excessive vibration at the low frequency of 1 x rpm of the belt (not of the rotor).
