The invention discloses a straight airfoil folding mechanism which is suitable for folding an outer wing folding section of a wing relative to an inner wing fixing section of the wing, and solves the inevitable problem of wing surface bulge caused by avoiding wing folding interference in single-hinge folding by adopting a cross folding mode under the arrangement of a fixing seat, a rotating shell and a fixing shell. An output mechanism reduces the wing space occupied by the folding mechanism, the mass of the whole mechanism is greatly reduced, the series axial connection is matched with the folding torque shunt multi-point output, the high output kinetic energy capacity is achieved, and then large-tonnage wing folding is achieved. An output mechanism with high output capacity and reliable holding capacity is formed by using a gear transmission technology with high integration level and smaller size; meanwhile, the equipment size and weight are reduced, the maintenance difficulty is reduced, and under the ingenious design of a driven pin shaft and a steel ball, the precision of pushing the distance between the steel ball and the pin shaft is reduced due to the good guiding performance of the spherical surface; and engineering implementation difficulties are simplified.
本发明公开了一种平直翼面折叠机构,适用于机翼外翼折叠段相对于机翼内翼固定段的折叠,在固定座、转动壳体及固定壳体的设置下,采用交叉折叠的方式解决了单铰链折叠因避免机翼折叠干涉而必然存在的翼面凸起问题,输出机构缩小了折叠机构占用的机翼空间、使整体机构质量大幅度减轻、串联的轴向连接配合折叠扭矩分流多点输出具备较强的输出动能能力进而实现大吨位机翼折叠、使用集成度高体积更小的齿轮传动技术形成输出能力强把持能力可靠的输出机构同时减少设备体积及重量降低维护保养难度,在从动销轴与钢球的巧妙设计下,由于具有球面良好的导向性能,降低了推动钢球与销轴距离的精度,使工程实现难度简化。
