Claim 12:
13. A phasing system for varying a rotational relationship between a first rotary component and a second rotary component, the phasing system comprising:
a gear hub;
a cradle rotor;
a spider rotor arranged between the gear hub and the cradle rotor, the spider rotor being configured to selectively lock and unlock relative rotation between the gear hub and the cradle rotor;
a first torsion spring and a second torsion spring coupled between the gear hub and the cradle rotor, wherein the first torsion spring is configured to apply a first torque load between the gear hub and the cradle rotor; and
a planetary actuator coupled to the gear hub and the spider rotor, the planetary actuator being operable between a steady-state mode where relative rotation between the gear hub and the cradle rotor is inhibited, and a phasing mode where the planetary actuator receives a rotary input at a predetermined magnitude to selectively provide a relative rotation between the gear hub and the cradle rotor.
