An aircraft (40) landing gear includes a main beam (52) coupled to an aircraft (40) for reciprocal movement between a stowed position and a deployed position. The actuator (100) is configured to drive reciprocating movement of the main beam (52). The actuator (100) includes a ball screw (140) and a motor (110). The motor (110) has an output shaft (112) operably coupled to the ball screw (140) by a gear train and configured to drive selective rotation of the ball screw (140). The actuator (100) also includes a disconnect mechanism (300) having a disconnect fitting (330), the disconnect fitting (330) being rotatably mounted to the ball screw (140). The biasing fitting (302) engages the disconnect fitting (330) to rotate the disconnect fitting (330) between a first position and a second position. The disconnect fitting (330) transmits rotation of the output shaft (112) to the ball screw (140) when the disconnect fitting (330) is in the first position. When the disconnect fitting (330) is in the second position, the ball screw (140) is isolated from the output shaft (112).

    一种飞行器(40)起落装置包括主梁(52),其联接到飞行器(40),用于在收起位置与展开位置之间往复移动。致动器(100)被配置为驱动主梁(52)的往复移动。致动器(100)包括滚珠丝杠(140)和马达(110)。马达(110)具有输出轴(112),其通过齿轮系可操作地联接到滚珠丝杠(140)并且被配置为驱动滚珠丝杠(140)的选择性旋转。致动器(100)还包括具有断开配件(330)的断开机构(300),该断开配件(330)可旋转地安装到滚珠丝杠(140)。偏置配件(302)接合断开配件(330),以使断开配件(330)在第一位置和第二位置之间旋转。当断开配件(330)处于第一位置时,断开配件(330)将输出轴(112)的旋转传递到滚珠丝杠(140)。当断开配件(330)处于第二位置时,滚珠丝杠(140)与输出轴(112)隔离。
