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.

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.

Abstract translation: 组合到钻柱的万向节在两个部件之间传递扭矩，其中部件的旋转可能不完全对齐。 万向接头包括各自连接到轴承元件的相对侧的上下纵向构件。 这些元件在间隔的径向位置处连接到轴承元件。 当接头旋转时，轴承元件在连接件之间弯曲以适应元件的不对准。 轴向力可以通过轴承元件以及扭矩传递。
