摘要： A hydrostatic extrusion method and apparatus for the extrusion of tubes is disclosed wherein the simplified structure of the nose or tip portion of the billet and the cooperating surfaces of the die defining the die cavity and those of the mandrel facilitate an improved initial sealing among the associated surfaces of the die, billet and mandrel. Such an initial sealing is effected between such interfaces of the members and billet at a point which is located substantially rearwardly from the position at which the actual extrusion to the final tubular configuration occurs between the bearing portion of the die and the cooperating sizing portion of the mandrel. Such structure and method permits the extrusion of tubes having walls of asymmetric or non-circular configurations in cross section, even those of complex configurations. In order to further enhance the efficacies of the present invention, the mandrel is provided with a head portion which may be replaced, or exchanged as desired, and a position-aligning member is associated with the mandrel in order to maintain the proper orientation of the mandrel relative to the die. The mandrel may also have a specifically designed configuration in order to provide the inner surface of the tube extruded with a gloss finish.

摘要： A pitch link for a rotary wing aircraft includes first and second shaft members threadingly engaged with each other. A first rod end is fixedly secured to the first shaft member and a second rod end is rotatably coupled to the second shaft member. First and second spherical bearings are mounted on the first and second rod ends, respectively. A guide member guides the first shaft member for movement in an axial direction of the first shaft with respect to the second shaft while preventing rotation of the first shaft.

摘要： A pitch link having an adjustable length is constructed as a diamond-shaped frame by coupling and fixing four flexible beams same in length and rigidity each at end portions thereof. Spherical bearings are provided on opposite ends with the longer diagonal line as an axis of the pitch link. A turnbuckle shaft is screwed into vertex portions on the shorter diagonal line, which is turned so as to adjust a length of the shorter diagonal line, thereby adjusting a length of the pitch link. The turnbuckle shaft is rotated by a detachable motor. Vibrations of a body and the rotational position of a rotor are detected by a vibrosensor and a phase detector respectively while an aircraft equipped with the pitch link is flying, an amount for adjusting the pitch link is calculated by a vibration analyzer from the electrical signals, and the motor is driven through a FM data transmitter/receiver to adjust the pitch link.
