The multi-axis momentum wheel system suitable for the microsatellite comprises a shell, the shell comprises an upper cover and a bottom shell, the bottom end of the upper cover is connected with the bottom shell through screws, four fixing bosses are installed on the top of the inner side of the bottom shell, and the top ends of the fixing bosses are connected with a fixing bottom plate through screws; four vertical side plates are mounted on the edge of the top end of the fixed bottom plate, inclined side plates are mounted at the top ends of the adjacent vertical side plates, and mounting clamping grooves are formed in the middles of the vertical side plates, the inclined side plates and the fixed bottom plate. By arranging the fixing boss, the fixing bottom plate, the vertical side plates, the inclined side plates, the mounting clamping grooves, the fixing holes, the rib plates, the motor, the mounting holes, the connecting shafts and inertia and arranging a plurality of flywheel structures at the same time, compared with a single flywheel, the flywheel is higher in integration level, small in size and light in weight, the included angle precision of all the shafts is guaranteed, and follow-up posture control is facilitated.
本发明公开了适用于微小卫星的多轴动量轮系统,包括壳体,所述壳体包括上盖和底壳,上盖的底端通过螺钉连接有底壳,所述底壳的内侧顶部安装有四个固定凸台,所述固定凸台的顶端通过螺钉连接有固定底板,所述固定底板顶端边部安装有四块竖直侧板,相邻所述竖直侧板的顶端安装有斜侧板,所述竖直侧板、斜侧板和固定底板的中部均开设有安装卡槽,本发明通过设置固定凸台、固定底板、竖直侧板、斜侧板、安装卡槽、固定孔、筋板、电机、安装孔、连接轴和惯量,同时设置多个飞轮结构,相较于单个飞轮集成度更高,体积小,质量轻,保证了各轴夹角精度,便于后续姿态控制。
