The invention belongs to the technical field of helicopter structure design, and discloses a universal hinge type propeller hub structure with a propeller hub elastic support and a working method of the universal hinge type propeller hub structure. The universal hinge type propeller hub structure comprises a ball cage constant-speed universal hinge type propeller hub, a propeller hub elastic support, a variable pitch assembly and a connecting support. The ball cage constant-speed universal hinge type propeller hub is used for being connected with a rotor wing shaft of a helicopter. The variable pitch assembly is installed on the ball cage constant velocity universal hinge type propeller hub and used for being connected with a propeller blade of a helicopter. The propeller hub elastic support is installed on the ball cage constant-speed universal hinge type propeller hub, the propeller hub elastic support is provided with a connecting support, and the connecting support is used for being connected with a rotor wing shaft of a helicopter; the propeller hub elastic support is used for supporting the ball cage constant-speed universal hinge type propeller hub and providing operation torque for the helicopter. According to the technical scheme, the invention discloses a ball cage constant-speed universal hinge type propeller hub structure containing a propeller hub elastic support. The technical defect that an existing traditional constant-speed universal hinge type propeller hub is difficult to provide operation torque can be overcome.
