The invention relates to a main lock for a reverse thrust actuation system. The main lock comprises a connector, a lock body and a lock body, wherein the connector is driven by a motor to rotate; the worm gear is fixedly connected to a main shaft of the reverse thrust actuation system; the worm is configured to be connected to the connector through a transmission mechanism and can be meshed with the worm gear to drive the worm gear to rotate; and an unlocking mechanism connected to the worm and operable to bring the main lock into a locked configuration, in which the transmission mechanism is connected to the joint and the worm to transmit a movement of the joint to the worm and the worm meshes with the worm wheel, or an unlocked configuration, in which the worm is disengaged from the worm wheel, in which the transmission mechanism is connected to the joint and the worm to transmit a movement of the joint to the worm and the worm meshes with the worm wheel. The worm gear is allowed to rotate freely.

    本发明涉及一种用于反推作动系统的主锁,包括:构造成由电机驱动而旋转的接头;固定地连接于反推作动系统的主轴的蜗轮;蜗杆,该蜗杆构造成能经由传动机构连接于接头,并且能与蜗轮啮合以带动蜗轮旋转;以及解锁机构,该解锁机构连接于蜗杆,并能被操作以使主锁进入锁止构造或解锁构造,其中,在锁止构造中,传动机构与接头和蜗杆连接,以将接头的运动传递给蜗杆,并且蜗杆与蜗轮啮合,并且其中,在解锁构造中,蜗杆与蜗轮脱开,以允许蜗轮自由旋转。
