The invention belongs to the technical field of tilt-rotor aircrafts, and discloses a universal joint pin universal hinge propeller hub for a tilt-rotor aircraft and a working method of the universal joint pin universal hinge propeller hub. The universal joint pin universal hinge propeller hub for the tilt rotor aircraft comprises a universal joint pin universal hinge, a propeller hub elastic bearing and a variable pitch hinge, the universal joint pin universal hinge comprises a universal joint pin, a universal hinge lock yoke, a first connecting piece, a second connecting piece and a propeller hub shell trifurcate piece. The propeller hub elastic bearing is used for being fixedly installed on the propeller hub shell trifurcate piece, and the propeller hub elastic bearing is located above the cross shaft; the variable pitch hinge is used for being installed on three supporting arms of a propeller hub shell trifurcate piece of the universal joint pin universal hinge. The universal joint pin universal hinge propeller hub disclosed by the invention is particularly a semi-hinged propeller hub structure, can meet the requirements of aircrafts with larger take-off weight levels, and can prolong the service life of the aircrafts and improve the reliability of the aircrafts.
