    摘要： A rotary torque-to-axial force energy conversion apparatus employs a rotatable member (30), a translatable member (32), and a magnetic coupling therebetween. The magnetic coupling converts a rotary torque on the rotatable member (30) to an axial force on the translatable member (32), and includes a first permanent magnet (31) comprising part of the rotatable member (30) and a second permanent magnet (33) comprising part of the translatable member (32). By way of example, the first permanent magnet (31) and the second permanent magnet (33) may each comprise interleaved, helical magnet sections of alternating polarity. A significant application of the energy conversion apparatus comprises an actuator apparatus for a ventricle assist device (VAD) or a total artificial heart (TAH). By oscillating the drive motor (100) energizing the rotatable member (30), an oscillating rotary torque is achieved that is converted by the magnetic coupling to a reciprocating axial motion on the translatable member (32). The reciprocating axial motion is employed within a Cleveland Clinic - type TAH to alternately actuate a first diaphragm coupled to the first ventricle and a second diaphragm coupled to a second ventricle for alternately pumping blood from the ventricles.

    摘要翻译： 旋转扭矩 - 轴向力能量转换装置使用可旋转构件，可平移构件和它们之间的磁耦合。 磁耦合将可旋转构件上的旋转扭矩转换成可平移构件上的轴向力，并且包括包括可旋转构件的一部分的第一永磁体和包括可平移构件的一部分的第二永磁体。 作为示例，第一永磁体和第二永磁体可以各自包括具有交替极性的交错的螺旋磁体部分。 能量转换装置的显着应用包括用于心室辅助装置（VAD）或总人造心脏（TAH）的致动器装置。 通过使驱动电动机振荡来激励可旋转构件，实现了通过磁耦合转换为可平移构件上的往复轴向运动的振荡旋转扭矩。 在克利夫兰诊所型TAH内使用往复式轴向运动来交替地致动联接到第一心室的第一隔膜和联接到第二心室的第二隔膜，以交替地从心室抽血。 还描述了轴向力 - 转动力矩能量转换装置。
