A helicopter main speed reducer propeller hub load simulation loading device comprises a lift force loading assembly, a shear loading assembly, a rotor wing loading bearing seat assembly and a bending moment loading assembly. The rotor wing loading bearing seat assembly comprises a bearing seat body, a lift force loading outer ring, a lift force loading inner ring, an inner ring rotating joint assembly and an outer ring rotating joint assembly; the lift force loading outer ring is connected with the lift force loading inner ring through the outer ring rotating joint assembly, and the lift force loading inner ring is connected with the bearing seat body through the inner ring rotating joint assembly; the bending moment loading assembly comprises a universal coupling, a torquemeter, a swing hydraulic cylinder assembly and a fixing plate, one end of the universal coupling is connected with the connecting shaft, and the swing hydraulic cylinder assembly is connected with the other end of the universal coupling through the torquemeter, so that torque load is applied to the bearing seat body, and bending moment loading of the rotor shaft is achieved. According to the invention, the influence of attitude change on the precision of the force loading assembly is reduced, and the loading stability and operability are improved.

    一种直升机主减速器桨榖载荷模拟加载装置,它包含升力加载组件、剪切加载组件、旋翼加载轴承座组件和弯矩加载组件;旋翼加载轴承座组件包含轴承座本体、升力加载外环、升力加载内环、内环旋转关节组件和外环旋转关节组件;升力加载外环通过外环旋转关节组件与升力加载内环连接,升力加载内环通过内环旋转关节组件与轴承座本体连接;弯矩加载组件包含万向联轴器、扭矩仪、摆动液压缸组件和固定板,万向联轴器的一端与连接轴相连,摆动液压缸组件通过扭矩仪与万向联轴器的另一端相连,使得施加力矩载荷在轴承座本体上,实现旋翼轴的弯矩加载。本发明降低了姿态变化对力加载组件的精度影响,提高了加载的稳定性与操作性。
