    • An actuator (2) comprises first and second linear motion devices, each able to extend the actuator (2) and arranged such that jamming of one of the first or second linear motion devices does not preclude operation of the other. The first linear motion device comprises a first linear screw (10), a first nut (12), and a first prime mover (14) arranged to impart relative linear motion between the screw and nut. Similarly, the second linear motion device comprises a second linear screw (20), a second nut (22), and a second prime mover (24) arranged to impart relative linear motion between the second screw and nut. The first linear screw (10) may have a bore (18) in which the second linear screw (20) is accommodated when the actuator (2) is in the retracted position.
    • 致动器(2)包括第一和第二线性运动装置,每个装置能够延伸致动器(2)并且布置成使得第一或第二直线运动装置中的一个的卡住不排除另一个的运行。 第一线性运动装置包括第一线性螺钉(10),第一螺母(12)和第一原动机(14),其布置成在螺钉和螺母之间施加相对的线性运动。 类似地,第二线性运动装置包括第二线性螺钉(20),第二螺母(22)和第二原动机(24),其布置成在第二螺钉和螺母之间施加相对的线性运动。 当致动器(2)处于缩回位置时,第一线性螺钉(10)可以具有孔(18),第二线性螺钉(20)容纳在其中。

    • An jam-tolerant actuator (2), comprises a housing (4), a first prime mover (6) for producing rotary motion, a first gearbox (10) arranged to convert in use the rotary motion from the first prime mover (6) into rotary motion. The first gearbox comprises a casing (14) mounted for rotation relative to the housing (4) of the actuator (2) and a second gearbox (16) arranged to convert rotary motion of the casing (14) of the first gearbox (10) into rotary motion. A brake (20) is arranged to act on the rotary motion from the second gearbox (16). In use when the first gearbox (10) is not jammed, the brake is applied to resist relative rotation between the casing of the first gearbox (10) and the housing (4) of the actuator (2). When the first gearbox (10) is jammed, the brake (20) is released thereby allowing the casing (14) of the first gearbox to rotate relative to the housing (4) of the actuator (2). A second motor (22) may also be provided.
    • 一种耐干扰致动器(2),包括壳体(4),用于产生旋转运动的第一原动机(6),布置成在使用中转换来自第一原动机(6)的旋转运动的第一齿轮箱(10) 转动。 第一变速箱包括安装成相对于致动器(2)的壳体(4)旋转的壳体(14)和布置成转换第一变速箱(10)的壳体(14)的旋转运动的第二变速箱(16) 转动。 制动器(20)布置成作用于来自第二齿轮箱(16)的旋转运动。 在第一变速箱(10)没有卡住的情况下使用时,施加制动以阻止第一变速箱(10)的壳体和致动器(2)的壳体(4)之间的相对旋转。 当第一变速箱(10)卡住时,制动器(20)被释放,从而允许第一变速箱的壳体(14)相对于致动器(2)的壳体(4)旋转。 也可以设置第二电动机(22)。
