    • The invention is an actuator assembly for actuating a door or aerodynamic surface of an aircraft. In detail, the invention includes a housing having first and second ends and a longitudinal axis. The housing center portion further includes first and second helical slots extending along the longitudinal axis. A cam follower, having first and second ends, is movably mounted in the center portion, the cam follower movable along the longitudinal axis of the housing. An actuator is provided for actuating the cam follower in first and second directions along the longitudinal axis. A bolt assembly, having first and second ends, is mounted through the cam follower with the first and second ends thereof extending into the first and second helical slots. First and second bearings are mounted to the first and second ends of bolt assembly such that the first and second bearings are movably mounted in the first and second helical slots. An actuation rod has its first end in the form of a clevis with first and second lugs movably connected to the first and second ends of the bolt assembly.
    • 本发明是用于致动飞机的门或空气动力学表面的致动器组件。 具体地,本发明包括具有第一和第二端和纵向轴线的壳体。 壳体中心部分还包括沿着纵向轴线延伸的第一和第二螺旋槽。 具有第一和第二端的凸轮从动件可移动地安装在中心部分中,凸轮从动件可沿壳体的纵向轴线移动。 提供致动器用于沿着纵向轴线在第一和第二方向上致动凸轮从动件。 具有第一和第二端的螺栓组件通过凸轮从动件安装,其第一和第二端延伸到第一和第二螺旋槽中。 第一和第二轴承安装到螺栓组件的第一和第二端,使得第一和第二轴承可移动地安装在第一和第二螺旋槽中。 致动杆的第一端具有U形夹的形式,其具有可移动地连接到螺栓组件的第一端和第二端的第一和第二凸耳。
