ABSTRACT:
A method of forming a torque tube (64) is provided. The method includes forming a fitting (80) having an elongated tube conforming area (88). The conforming area (88) includes chamfer areas (82) having upper surfaces (90), lower surfaces (92), and chamfer surfaces (94) that transition between the upper surfaces (90) and the lower surfaces (92) and have chamfer angles (96) of approximately 20 relative to the lower surfaces (92). An elongated tube (86) is procured and an end portion (106) of the elongated tube (86) is formed onto the conforming area (88) to form a torque-transmitting coupling (84). The torque tube (64) is also provided and formed according to the above-stated method.
