The invention relates to a flexible propeller hub axial hinge, a propeller hub and a rotor wing, belongs to the technical field of helicopters, and aims to solve the problem of poor aeroelastic stability of the helicopter rotor wing due to the fact that rotor wing shimmy cannot be efficiently absorbed. The flexible propeller hub axial hinge is used for bridging a central piece assembly and a propeller blade and comprises a functional part and a limiting part, the limiting part is arranged between the central part assembly and the functional part; the functional part comprises an oversleeve, a pulling and twisting sheet assembly and a laminated shimmy damping assembly; the limiting part comprises a supporting shaft assembly; the supporting shaft assembly comprises a supporting shaft and a rubber pad. The rubber pad is arranged between the supporting shaft and the stacked shimmy damping assembly. The flexible propeller hub axial hinge can generate a composite damping effect, efficiently absorb the centrifugal force and shimmy of the blades, and ensure the stable flight of a helicopter; the propeller hub can ensure that the helicopter has maneuverability and following performance; the rotor provided by the invention can improve the flight performance of the helicopter.
