Tangential link swashplate centering member

A centering member for centering about a rotorshaft and for allowing to tilt and to translate a swashplate having a rotating inner ring attached to the rotorshaft and a stationary outer ring attached to an airframe stationary component, comprising:

• first lugs (34-36) attached to the rotorshaft and equally spaced thereabout;
• second lugs (40-42) attached to the inner ring and equally spaced thereabout;
• and
• equal-length links (48-50), equal-length links (48-50), each attached at one end via spherical bearings (52-54) to the first lugs and at the other end via spherical bearings (56-58) to the second lugs, wherein the links are generally tangential to the rotorshaft for restraining, centering, and allowing for collective and cyclic movement of a swashplate.

A centering member for centering about a rotorshaft and for allowing to tilt and to translate a swashplate having a rotating inner ring attached to the rotorshaft and a stationary outer ring attached to an airframe stationary component, comprising:

• first lugs (74) attached to the airframe stationary component and equally spaced about the rotorshaft for restraining, centering, and allowing for collective and cyclic movement of a swashplate;
• second lugs (66-68) attached to the outer ring and equally spaced thereabout;
• and
• equal-length links (70-72), each attached at one end via spherical bearings (80-82) to the first lugs and at the other end via spherical bearings (76-78) to the second lugs, wherein the links are tangential to the outer ring.
