The invention discloses a transmission mechanism of a wing electric folding system. The transmission mechanism of the wing electric folding system comprises a shell and an input shaft. According to the transmission mechanism of the wing electric folding system, an NGWN (I) type gear ring E is adopted as final-stage output, meanwhile, the gear ring E and a first connecting rod in a folding mechanism are integrally formed, so that the transmission mode of a rotation driving mechanism is expanded, moreover, the reduction ratio of an NGW type planetary reducer is 2.8-9, the reduction ratio of an NGWN (I) type planetary reducer is 20-100, under the same size of driving mechanisms, the NGWN (I) type planetary reducer can be used for achieving a higher transmission ratio, moreover, the size of the driving mechanism can be effectively reduced, the number of planet gears of an existing NGW type planetary reducer is 3-5, the number of planet gears of the transmission mechanism of the wing electric folding system can reach up to eight, then stress of the transmission mechanism is more balanced, due to the fact that a limiting sector ring serves as a mechanical limiting device, the gear ring Eand the first connecting rod can only rotate within an angle alpha, so that the transmission mechanism operates within a limited angle, then the dead point position of the folding mechanism can be avoided, and the safety of the wing folding system can be protected.
本发明公开了一种机翼电动折叠系统的传动机构,包括壳体和输入轴,本发明采用了NGWN(Ⅰ)型的齿圈E作为末级输出,同时将齿圈E与折叠机构中的第一连杆一体成型,拓展了旋转驱动机构的传动形式,且NGW型行星减速器减速比为2.8~9,NGWN(Ⅰ)型行星减速器减速比为20~100,在驱动机构相同的体积下,使用NGWN(Ⅰ)型行星减速器能实现更高的传动比,且能有效减小驱动机构体积大小,现有的NGW型行星减速器的行星轮为3~5个,本发明的行星轮个数可高达八个,进而使得该机构受力更均衡,由于限位扇环作为机械限位装置,齿圈E和第一连杆只能在角度α内旋转,使本传动机构在有限角度内运行,有利于避开折叠机构死点位置,保护机翼折叠系统安全。
