Abstract

A method for bonding a tubular shaft to an end fitting to produce an assembly wherein the shaft and the end fitting are in axial alignment and which is capable of transmitting high torque, said method employing an end fitting provided with a mating section having two concentric cylindrical walls which describe an annular cavity or socket adapted to receive the tubular shaft therein. The high torque carrying capacity of the joint produced in accordance with the invention results from the fact that the shaft is bonded to the mating section of the end fitting on both its interior and exterior surfaces and is in axial alignment with the end fitting. Such axial alignment results from the presence of a resilient sealing ring and an annular shoulder, positioned near the top and base of the inner cylindrical wall of the mating section, which contact the inner surface of the tubular shaft and center the shaft around said wall when the shaft is inserted into the bonding socket of the end fitting.
