  • Universal joint
    Patent number: 10619678
    Abstract: A universal joint assembled to a drill string transfers torque between two components where rotation of the components may not be completely aligned. The universal joint includes upper and lower longitudinal members each connected to opposite sides of a bearing element. The elements are connected to the bearing element at spaced radial positions. As the joint rotates the bearing element flexes between the connections to accommodate misalignment of the elements. Axial force can be transferred through the bearing element as well as torque.
    Type: Grant

  • Universal joint
    Patent number: 10337261
    Abstract: 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.
