A rotary actuator for a hinged panel assembly, e.g., of a fixed-wing aircraft, includes ball bearings, an outer cylinder, a piston, and an inner shaft. The outer cylinder admits fluid pressure from a fluid pressure supply. The piston is circumscribed by the outer cylinder. The piston, outer cylinder, and ball bearings collectively forming an outer ball screw. The piston translates along a longitudinal center axis in response to the fluid pressure. The inner shaft is circumscribed by the piston, with the inner shaft, piston, and ball bearings collectively forming an inner ball screw that is concentric with the outer ball screw. The ball screws form an interlaced ball circuit with one or more shared ball paths. Piston translation rotates the piston and inner shaft, and to thereby recirculates the ball bearings between the outer ball screw and the inner ball screw through the interlaced ball circuit.

    一种旋转致动器,用于例如固定翼飞机的铰接面板组件,该旋转致动器包括滚珠、外筒、活塞和内轴。外筒允许来自流体压力供应部的流体压力。活塞由外筒外接。活塞、外筒和滚珠共同形成外滚珠丝杠。活塞响应于流体压力沿纵向中心轴线平移。内轴由活塞外接,其中内轴、活塞和滚珠共同形成与外滚珠丝杠同轴的内滚珠丝杠。滚珠丝杠形成具有一个或多个共享滚珠路径的交错的滚珠回路。活塞平移使该活塞和内轴旋转,从而使滚珠通过交错的滚珠回路在外滚珠丝杠和内滚珠丝杠之间再循环。
