SYNCHRONIZED TUBULAR FRICTION WELDING ARRANGEMENT

摘要

Method and apparatus for friction welding termination elements at first and second ends 21, 23 of a cylindrical shaft 15 in alaignment with an axis. A shaft receiver 17 receives the cylindrical shaft 15, and a first chuck 70 grips and rotates the cylindrical shaft 15 in alignment with the axis. A second chuck 75 grips the cylindrical shaft 15 and translates the second chuck 75 between first and second axial positions. A first termination receiver 155 receives the first termination 30 and axially translates same to a first installation position. An installation drive 90 urges the first termination 30 axially toward the cylindrical shaft 15 as it is rotated. A second termination receiver axially translates second termination 32 to a second installtion position in allignment with the axis. A second installation drive 91 urges the second termination element 32 axially toward the cylindrical shaft as it is rotated. The first chuck 70 is rotated at approximately between 500 to 6000 rmp. The first installation drive arrangement 90 applies between 250 to 3000 pounds of axial force for between 1 and 15 seconds during a heating phase, and between 1500 to 12000 pounds of axial force for between 0.5 and 10 seconds during a forging phase.
