The invention discloses a firer rotation driving device capable of outputting torque. The firer rotation driving device comprises a hollow shell structure; the igniter is arranged at one end of the hollow shell structure and used for outputting axial power to an inner cavity of the hollow shell structure; the spiral motion structure is located in an inner cavity of the hollow shell structure and used for moving along a spiral track under the action of power output by the igniter; the torque transmission structure is arranged on the hollow shell structure, the torque transmission structure and the hollow shell structure can rotate relative to each other but limit the degree of freedom of relative axial sliding, one part of the torque transmission structure is connected with the spiral motion structure, and the torque transmission structure and the spiral motion structure can slide relative to each other in the axial direction but limit the degree of freedom of relative rotation; therefore, the torque transmission structure is driven by the spiral motion structure to rotate, and the other part of the torque transmission structure is located outside the hollow shell structure to output torque. The pyrotechnic rotation driving device can give full play to the advantages of small size and strong driving capability of the pyrotechnic rotation driving device.
本发明公开了一种输出扭矩的火工旋转驱动装置,包括:中空壳体结构;点火器,设置于中空壳体结构的一端,用于向中空壳体结构的内腔输出轴向动力;螺旋运动结构,位于中空壳体结构的内腔中,用于在点火器输出的动力作用下沿螺旋轨迹运动;扭矩传递结构,设置在中空壳体结构上,扭矩传递结构与中空壳体结构能够相对转动,但限制相对轴向滑动的自由度,扭矩传递结构的一部分与螺旋运动结构连接,扭矩传递结构与螺旋运动结构能够相对轴向滑动,但限制相对转动的自由度,从而扭矩传递结构在螺旋运动结构的带动下转动,扭矩传递结构的另一部分位于中空壳体结构外部以输出扭矩。该火工旋转驱动装置能够充分发挥火工作动装置体积小驱动能力强的优势。
