The invention discloses a compound gear, a speed reduction transmission assembly and an aircraft, and relates to the field of transmission devices of aircrafts. The compound gear comprises a web plate, the web plate is of a laminated plate structure integrally formed by die pressing of a continuous fiber reinforced composite material, and a center hole is formed in the center of the web plate; the hub is arranged at the center hole in a matched mode, and the hub is a metal piece; the gear ring is connected to the web plate, the gear ring and the hub are coaxially arranged, meshing teeth distributed at intervals in the circumferential direction are arranged on the gear ring, and the gear ring is a metal piece. According to the compound gear disclosed by the embodiment of the invention, the web plate between the gear ring and the hub adopts the laminated plate structure integrally molded by the continuous fiber reinforced composite material through mould pressing, so that high strength and durability are kept while the weight is reduced, and the flight burden can be reduced.

    本发明公开了一种复合齿轮、减速传动组件和飞行器,涉及飞行器的传动装置领域。复合齿轮包括:腹板,腹板为采用连续纤维增强复合材料模压一体成型的层板结构,腹板的中心具有中心孔;轮毂,轮毂配合在中心孔处,轮毂为金属件;齿圈,齿圈连接在腹板上,齿圈与轮毂同轴设置,齿圈上设有沿周向间隔分布的啮合齿,齿圈为金属件。根据本发明实施例的复合齿轮,齿圈与轮毂之间的腹板采用连续纤维增强复合材料模压一体成型的层板结构,在减轻重量的同时保持高强度和耐久性,可以减轻飞行负担。
