摘要： The disclosure describes a constant velocity joint assembly for use in transmitting torque. The constant velocity joint assembly includes members that are connected in series via tongue-and-groove connections in a swivel joint pattern that allows for transferring torque between two skew lines, and further provide freedom of movement such that rotation about one longitudinal axis can be transformed into rotation about another longitudinal axis that is not aligned with the first longitudinal axis. Thus, the members of the constant velocity joint assembly do not necessarily need to share a common longitudinal axis.
摘要翻译：本公开描述了用于传递扭矩的等速万向节组件。等速度接头组件包括通过榫槽连接以旋转接头图案串联连接的构件，其允许在两条歪斜线之间传递扭矩，并进一步提供移动的自由度，使得围绕一个纵向轴线的旋转可以变换围绕不与第一纵向轴线对准的另一纵向轴线旋转。因此，等速万向节组件的构件不一定需要共享共同的纵向轴线。

摘要： A driveshaft assembly for a downhole motor including a driveshaft having a longitudinal axis, first and second ends, and a convex spherical bearing surface disposed at the first end configured to transfer axial loads. The assembly also includes a connection lug disposed at the driveshaft first end, extending circumferentially between first and second ends, and including a recess in the first end of the lug, the recess comprising a concave cylindrical surface concentrically disposed about a pivot axis oriented orthogonal to the longitudinal axis. The assembly also includes a torque transfer key disposed within the recess and having a central axis radially spaced from the pivot axis, a convex cylindrical surface concentrically disposed about the pivot axis, and a planar surface. The convex cylindrical surface of the key slidingly engages the concave cylindrical surface of the recess; and the pivot axis intersects the key.

摘要： Fitting yokes are coupled each by a universal joint of the trunnion type to the opposite ends of a shaft assembly biased for axial extension. Each of the fitting yokes has a sleeve inserted in a center bored portion of the universal joint with a clearance formed therebetween to permit relative angular displacement between the axis of the shaft assembly and the axis of the fitting yoke. The drive shaft therefore has a greatly reduced length in its entirety. The shaft assembly includes a splined portion adapted to permit collapsing and extension of the assembly and circumferentially covered with a sleeve-shaped cover. The cover defines an interior space holding a lubricant to lubricate the spline portion for sliding movement.
