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 an axis supporting part and a gear ring. The gear ring is connected to the axis supporting part, the gear ring and the axis supporting part 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. The axis supporting part is of a laminated plate structure integrally formed by continuous fiber reinforced composite materials in a mold pressing mode. According to the compound gear disclosed by the embodiment of the invention, the axis supporting part 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:轴心支撑部和齿圈。齿圈连接在轴心支撑部上,齿圈与轴心支撑部同轴设置,齿圈上设有沿周向间隔分布的啮合齿,齿圈为金属件。轴心支撑部为连续纤维增强复合材料模压一体成型的层板结构。根据本发明实施例的复合齿轮,轴心支撑部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。
