The invention belongs to the technical field of rotorcrafts, and particularly relates to an autorotorcraft pre-rotation driving flexible shaft device which comprises a center positioning shaft, an elastic layer set is arranged on the outer side of the center positioning shaft in a sleeving mode, the elastic layer set and the center positioning shaft are coaxially arranged, and a sheath assembly is arranged on the outer side of the elastic layer set; the elastic layer group comprises a plurality of elastic layers which are sequentially arranged from inside to outside, the plurality of elastic layers are coaxially arranged, and the elastic layer located at the inner edge and the central positioning shaft are coaxially arranged. According to the flexible shaft, the elastic layer set changes along with the bending degree and the torque of the flexible shaft, the elastic layers in the elastic layer set support and limit each other in the deformation process, and therefore it is guaranteed that the shaft body has a large output torque range within a certain bending range.

    本发明属旋翼机技术领域,尤其涉及一种自转旋翼机预旋转驱动软轴装置,包括:中心定位轴,所述中心定位轴的外侧套设有弹性层组,所述弹性层组与所述中心定位轴同轴设置,所述弹性层组的外侧设置有护套组件;所述弹性层组包括由内向外依次设置的若干弹性层,若干所述弹性层同轴设置,位于内缘处的所述弹性层与所述中心定位轴同轴设置。本发明中,弹性层组随着软轴的弯度和扭矩变化,弹性层组中的各弹性层在变形过程中,相互支撑限制,从而保证了本发明的轴体在一定的弯曲范围内,具有较大的输出扭矩范围。
