【 中文摘要 】本发明公开的一种旋转粘滞阻尼器装置，包括阻尼器外筒和齿形拉压杆，阻尼器外筒的储能腔内设有叶片，叶片转动连接于储能腔的导杆内，导杆顶端固定有齿轮，该齿轮与叶片同轴转动，齿轮与齿形拉压杆相互啮合，将齿形拉压杆的平动位移转化为叶片的转动位移，使得阻尼器位移量的工作范围不再被限制，阻尼器的应用将更加广泛；储能腔与叶片之间的间隙内填充有粘滞液体，叶片上设有若干个节流孔，若干个节流孔内填充有粘滞液体且若干个节流孔与间隙连通，当叶片在储能腔内转动时，受到节流孔与粘滞液体造成的阻力，使得阻尼器的工作性能更好。

【 英文摘要 】The invention discloses a rotary viscous damper device which comprises a damper outer cylinder and a toothed tension and compression rod. A blade is disposed in an energy storage chamber of the damperouter cylinder and rotatably connected into a guide rod of the energy storage chamber, a gear is fixed to the top of the guide rod, the gear and the blade coaxially rotate, the gear is meshed with the toothed tension and compression rod, the translation displacement of the toothed tension and compression rod is converted into rotary displacement of the blade, so that the working range of the displacement of a damper is no longer restrained, and applications of the damper are wider; a gap between the energy storage chamber and the blade is filled with a viscous liquid, the blade is provided with a plurality of orifices, and the plurality of orifices are filled with the viscous liquid and communicated with the gap. When the blade rotates in the energy storage chamber, the blade is subjectedto resistance caused by the orifices and the viscous liquid, so that the working performance of the damper is better.
