The HH coupling is considered a safety jaw coupling that has progressive characteristics. For instance the dynamic torsional stiffness is enhanced while increasing the coupling load. This type of feature offers a distinct advantage in applications where a wide range is used and the torque increases with speed. The resulting characteristics provide the HH coupling with a relatively low torsional stiffness that places the critical speed (resonance) below the operational speed of the system.
