Abstract:
A universal joint assembled in a drill string transfers torque between two components where the shafts of the components are not completely aligned. The universal joint includes two members each with pin connections on one end and axially extending arms on the other end. The axially extending arms intermesh when the members are assembled defining a closed cavity between the arms. The cavity retains a ball bearing held between two seats. The universal joint when assembled to portions of the drill string at the pins on each end transfer torque by intermeshing of the teeth. Axial force is transferred through the seats holding the ball bearing.
