发明名称 UNIVERSAL JOINT
摘要 A universal joint assembled to a drill string transfers torque and axial force between two components along a longitudinal axis where the shafts of the components are not completely aligned. The universal joint includes axially spaced members joined by transversely spaced links. As the joint rotates the links move to accommodate misalignment between the drill string components and the connected members.
