The invention relates to a flywheel structure with a micro-vibration suppression device for a satellite and application thereof. The flywheel structure comprises an upper shell, a wheel body, a direct-current brushless motor, a motor mounting base and a counter weight mass block, the direct-current brushless motor is fixed to the motor mounting base, the wheel body is arranged on an output shaft of the direct-current brushless motor, the output shaft of the direct-current brushless motor is connected with the upper shell through a bearing, a C-shaped frame is arranged on the motor mounting base in a surrounding mode, a damping spring is arranged on the C-shaped frame, the damping spring penetrates through the motor mounting base to be connected with the counter weight mass block, damping rubber balls are evenly arranged between the counter weight mass block and the motor mounting base, and a lower shell is arranged on the lower side of the motor mounting base and connected with a satellite mounting base. According to the flywheel structure with the micro-vibration suppression device for the satellite, the structure is simple and compact, the vibration reduction structure is arranged inside a flywheel, micro-vibration suppression is carried out at the source of the flywheel through the vibration reduction structure, it is avoided that vibration reduction design is additionally arranged on a satellite body structure, the universality of the single flywheel for different types of satellites is improved, the satellite development cost is reduced, and the satellite development time is shortened.
本发明涉及一种自带微振动抑制装置的卫星用飞轮结构及其应用,包括上壳体、轮体、直流无刷电机、电机安装座和配重质量块,电机安装座上固定直流无刷电机,直流无刷电机输出轴上设置轮体,直流无刷电机输出轴通过轴承连接上壳体,电机安装座上环绕设置C型架,C型架上设置减振弹簧,减振弹簧穿过电机安装座连接配重质量块,配重质量块与电机安装座之间均匀设置减振橡胶球,电机安装座下侧设置下壳体,下壳体连接卫星安装基座。本发明结构简单紧凑,在飞轮内部设置减振结构,利用减振结构在飞轮源头处进行微振动抑制,避免在卫星本体结构上增加减振设计,既提高了单个飞轮对于不同类型卫星的通用性,又降低了卫星研制成本,缩短了卫星研制时间。
