Abstract: A universal joint assembled to a drill string transfers torque and axial force between two components where the shafts of the components are not completely aligned. The universal joint includes end members connected to opposite ends of a cable for connecting to components of the drill string. As the joint rotates the cable flexes to accommodate misalignment between the connected drill string components.
Abstract translation: 组合到钻柱的万向接头在两个部件之间传递扭矩和轴向力，其中部件的轴不完全对准。 万向接头包括连接到电缆的相对端的端部构件，用于连接到钻柱的部件。 当接头旋转时，电缆弯曲以适应所连接的钻柱部件之间的未对准。
