The invention discloses a cylindrical rotary throwing type driving unlocking mechanism which is characterized by comprising a rotary driving mechanism (1), a Hall sensor (2), a pressing and releasing assembly (3), a spring separating device (6), a self-lubricating bearing assembly (4) and a pin puller locking device (5). The rotary driving mechanism (1) comprises a combined permanent magnet synchronous motor, a motor output shaft (15), a harmonic reducer (22), a rotary driving mechanism output shaft (17), a flange double-row angular contact ball bearing (16), an output shaft adapter (18) and a reducer shell (21), after an aircraft enters an orbit, the pin puller locking device (5) is unlocked firstly, the compression release assembly (3) receives an instruction, unlocking is released, the spring separation device (6) works, and the pin puller locking device (5) and the spring separation device (6) are locked. And the separating body (7) is separated from the aircraft body under the action of spring force. The invention has the advantages of large driving torque margin, light weight, high safety and reliability, small envelope volume and strong vibration and impact resistance.

    本发明公开了一种筒状旋转抛离式驱动解锁机构,其特征在于,包括:旋转驱动机构(1)、霍尔传感器(2)、压紧释放组件(3)、弹簧分离装置(6)、自润滑轴承组件(4)和拔销器锁定装置(5);旋转驱动机构(1)包括:组合式永磁同步电机、电机输出轴(15)、谐波减速器(22)、旋转驱动机构输出轴(17)、凸缘双列角接触球轴承(16)、输出轴转接件(18)、减速器壳体(21),在飞行器入轨之后,拔销器锁定装置(5)首先解锁,压紧释放组件(3)接收指令,解锁释放,弹簧分离装置(6)工作,分离体(7)在弹簧力作用下与飞行器本体分离。本发明驱动力矩裕度大、重量轻、安全可靠性高、包络体积小、抗振动冲击能力强。
