摘要： An electrical submersible pump assembly has modules, including a pump, a seal section and a motor. A rotatable first drive shaft in a first one of the modules has a splined end that mates with a splined end of a rotatable second drive shaft in a second one of the modules. An external set of splines is on mating ends of the first drive shaft and the second drive shaft. A coupling has an internal set of splines that mesh with the external set to rotationally couple the first and second drive shafts to each other. A polymer coating is selectively bonded on one of the sets and in sliding engagement with the other set. The coating is a solid polymer material having a lower coefficient of friction than steel alloys of the internal set and the external set.

摘要： A drive-side concavo-convex part (26, 26a) is made to engage the half of a cup-side concavo-convex part (35) which is on the other side in the axial direction, while the central axes of a drive shaft (12a) and a driven shaft (8a) are aligned with each other, and drive-side gaps (36, 36a), the width of which in the circumferential direction increases toward the other side in the axial direction, are interposed between the circumferential side surface of each drive-side convex part (25, 25a) and the circumferential side surface of each cup-side convex part (34). In addition, a driven-side concavo-convex part (32, 32a) is made to engage the half of the cup-side concavo-convex part (35) which is on the one side in the axial direction, while the central axes of the drive shaft (12a) and the driven shaft (8a) are aligned with each other, and driven-side gaps (37, 37a), the width of which in the circumferential direction increases toward the one side in the axial direction, are interposed between the circumferential side surface of each driven-side convex part (31, 31a) and the circumferential side surface of each cup-side convex part (34).

摘要： A coupling (200) includes a first element (210) having an annular projection (210) and a second element (240) having an annular recess (250). Both the first element (210) and the second element (240) have a common axis (205). A radius of the annular projection (210) varies circumferentially around the axis (205) to thereby define a connection profile (270). The annular projection (210) is removably accommodated within the annular recess (250) to couple the first (210) and second (240) elements to one another.

摘要： A drive shaft assembly comprising a first shaft (32) and a second shaft (34) is disclosed. The second shaft (34) is axially translatable from an engaged configuration with the first shaft at one limit of its travel to a disengaged configuration from the first shaft at the opposite limit of its travel. Engagement of the first and second shafts is via cooperating helical splines (38) provided thereon. The helical splines (38) give rise to a disengaging axial force on the second shaft (34) in a fault condition in which a driving torque is applied from one of the first and second shafts to the helical splines (38) in a rotational direction tending to unscrew the helical splines (38). Consequently when the second shaft (34) is in the engaged configuration the disengaging axial force translates the second shaft (34) to the disengaged configuration.
摘要翻译：公开了一种包括第一轴（32）和第二轴（34）的驱动轴组件。第二轴（34）可以在其行进的一个极限处与第一轴的接合构型轴向平移，在其行进的相反极限处与第一轴脱离配置。第一和第二轴的接合是通过配合在其上的螺旋花键（38）。螺旋花键（38）在故障状态下在第二轴（34）上产生分离轴向力，其中驱动扭矩从第一和第二轴之一沿旋转方向施加到螺旋花键（38）倾向于拧开螺旋花键（38）。因此，当第二轴（34）处于接合构型时，分离轴向力使第二轴（34）平移到分离构型。
