The invention relates to the technical field of dampers, and provides a passive rotary damper which comprises an outer sleeve component and a damping component arranged in the outer sleeve component. The damping component is provided with a driving input rotor and elastic damping reeds arranged in the circumferential direction of the driving input rotor, and when the driving input rotor rotates, due to elastic interference of the elastic damping reeds, the driving input rotor is subjected to damping torque, and then the movement speed of the driving input rotor is reduced. The elastic interference allows the drive input rotor to rotate through an elastic damping reed. According to the brand new passive rotary damper, energy in the rotating process is consumed mainly through extrusion elastic force and sliding friction force of the elastic reeds, so that the relative unfolding speed of an antenna or a sailboard is reduced, and the novel passive rotary damper has the advantages of being simple in structure, light in weight, small in temperature influence and the like. And the reliability of the whole spacecraft unfolding system can be greatly improved.

    本发明涉及阻尼器技术领域,提供了一种被动式旋转阻尼器,包括外套部件以及布置在所述外套部件中的阻尼部件;所述阻尼部件配置有驱动输入转子以及沿所述驱动输入转子周向布置的弹性阻尼簧片,当所述驱动输入转子转动时由于所述弹性阻尼簧片的弹性干涉使得所述驱动输入转子受到阻尼力矩进而减小所述驱动输入转子的运动速度,其中,所述弹性干涉允许所述驱动输入转子转动通过弹性阻尼簧片。本发明提出了一种全新的被动式旋转阻尼器,主要通过弹性簧片的挤压弹性力和滑动摩擦力来消耗转动过程中的能量,从而减小天线或帆板的相对展开速度,具有结构简单、重量轻、受温度影响小等特点,可以极大的提高整个航天器展开系统的可靠性。
