The invention provides a rotor wing propeller hub centering structure of a rotorcraft and the rotorcraft, and relates to the technical field of rotorcraft design, the rotor wing propeller hub centering structure is used for centering and assembling a propeller hub of the rotorcraft on a rotor wing shaft of the rotorcraft, the propeller hub is connected with the rotor wing shaft through a spline, the centering structure comprises two centering rings, the two centering rings are connected and clamped on the rotor wing shaft in a sleeving mode, and the two centering rings are connected through a spline. The two centering rings are respectively arranged above and below the propeller hub; the rotor shaft is sleeved with the two bearing parts, the two bearing parts are connected to the top and the bottom of the propeller hub correspondingly, and the top and the bottom of the inner side of one bearing part are connected with one centering ring and the top of the inner side of the propeller hub in an attached mode through conical surfaces correspondingly; the bottom and the top of the inner side of the other bearing component are connected with the bottom of the inner side of the other centering ring and the bottom of the inner side of the propeller hub in an attached mode through conical surfaces. The coaxiality of the propeller hub and the rotor shaft is effectively guaranteed, high-precision centering of the propeller hub is achieved, precise control over the torque of the rotor is facilitated, and the maneuverability of the whole machine is improved.
