摘要： A drive shaft assembly for a downhole motor includes a drive shaft formed with convexly spherical bearing surfaces on each end, and end housings with concavely spherical bearing surfaces for mating contact with the spherical bearing surfaces of the drive shaft, thereby facilitating omni-directional articulation between the drive shaft and the end housings while transferring axial thrust loads between the drive shaft and end housings across the interface of the mating spherical bearing surfaces. Torque is transferred between the drive shaft and end housings through two or alternatively four swivelling drive keys mounted to each end of the drive shaft and engageable with complementary drive key slots in the end housings. Full and constant torque-transferring contact is thus provided between the swivelling drive keys and the end housings irrespective of any angular offset between the drive shaft and the end housings, resulting from omni-directional articulation of the drive shaft relative to the end housing. The omni-directional center of rotation at each end of the drive shaft coincides with the geometric centerpoint of the corresponding convexly spherical bearing surface, which corresponds to the intersection of the drive shaft's rotational axis, the end housing's rotational axis, and the drive key swivel axis.
摘要翻译：用于井下电动机的驱动轴组件包括在每个端部上形成有凸起的球面轴承表面的驱动轴和具有凹入球形的轴承表面的端部壳体，用于与驱动轴的球面轴承表面配合接触，从而有助于全方位的铰接驱动轴和端部壳体，同时在配合的球面轴承表面的接口之间传递驱动轴和端部壳体之间的轴向推力载荷。扭矩通过安装在驱动轴的每一端的两个或四个旋转驱动键在驱动轴和端部壳体之间传递，并可与端部壳体中的互补驱动键槽接合。因此，由于驱动轴相对于端部壳体的全方向铰接，所以在旋转驱动键和端部壳体之间提供完全和恒定的转矩传递触点，而与驱动轴和端部壳体之间的任何角度偏移无关。驱动轴每端的全向旋转中心与对应的凸形球面轴承表面的几何中心点重合，该中心点对应于驱动轴的旋转轴线，端部壳体的旋转轴线和驱动键旋转轴线的交点轴。

摘要： A constant velocity universal joint of the tripode type increases the torque transmitting capacity of the joint while the size of the joint remains unchanged, and, respectively, with a predetermined torque capacity, to reduce the size of the joint, especially the outer diameter of the joint. This is achieved in that the joint is guided entirely by the outer roller and that the securing means for the roller assembly on the tripode arm are displaced radially inwardly with reference to the joint axis.
