The invention discloses a folding device for folding aircraft blades, which comprises a base, a first shell and a connecting disc, the connecting disc is oppositely connected with two blades through a folding assembly, the folding device is arranged in the first shell, and the folding device comprises a second shell and a planetary gear mechanism arranged in the second shell. The planetary gear mechanism is connected with a motor, two locking pieces are correspondingly arranged on the side wall of the gear ring and are matched in the blocking grooves, two sliding ways are oppositely arranged on the bottom face of the connecting disc, limiting shafts are arranged on the locking pieces and are matched in the sliding ways, and the locking pieces are matched with the sliding ways. The single motor drives the single actuator to fold and unfold the two blades through the folding assembly, the structure is compact, the weight is light, flight work is more facilitated, the risk of mutual interference cannot be generated during work of the single actuator, and reliability is high.
本发明公开了一种用于飞行器桨叶折叠的折叠装置,包括底座、第一壳体、连接盘,连接盘通过折叠组件对置连接有两个桨叶,折叠装置设置在第一壳体内,折叠装置包括第二壳体以及设置在第二壳体内的行星齿轮机构,行星齿轮机构连接有电机,齿圈的侧壁处对应设置有两个锁定件,锁定件适配在挡槽内,连接盘的底面上对置有两个滑道,锁定件上具有限位轴,限位轴适配在滑道内,通过单个电机驱动单个作动器通过折叠组件实现对两个桨叶的折叠与展开,结构紧凑、重量轻,更有利于飞行工作,单个作动器工作不会产生互相干扰的风险,可靠性高。
