ABSTRACT:
A torque joint for transmission of force in both longitudinal and circumferential direction about thin-wall tubular torque tubes is provided by overlapping an inner one of said tubes and an outer one of said tubes, inserting a mandrel having longitudinal and circumferential slots therein, applying a deformation force for pressing the tubular members into the slots of the mandrels, and extracting at least a portion of the mandrel to provide the torque joint. In the case wherein two open-ended tubular members are employed, two mandrel elements of the same form are utilized, the two mandrel elements being withdrawn from the opposite ends of the joint upon completion of assembly of the joint. In the event that one of the tubular elements is closed ended, a retaining ring is utilized as one of the mandrel elements, in which case only one mandrel element is withdrawn while the ring remains captured between a circumferential groove of the joint and the closed end of the tube.
