The invention relates to the technical field of engineering structure damping, in particular to a gapless viscous fluid damper and an installation method thereof. Comprising a cylinder barrel, a compression nut, a rod end connecting lug ring, a cylinder end connecting lug ring, a gapless pin shaft, a rod end guide sleeve, a rod end piston rod and a piston, the rod end guide sleeve, the rod end piston rod and the piston are sequentially arranged in the cylinder barrel in the axial direction of the cylinder barrel, the cylinder end piston rod, the cylinder end guide sleeve, the rod end piston rod and the cylinder end piston rod are in threaded connection with the piston, and small locking gaskets are arranged at the threaded connection positions. The small locking gasket comprises two circular rings which are coaxially and rotationally matched, self-locking conical surfaces are arranged on the side walls, close to each other, of the circular rings, and when the two circular rings coaxially and relatively rotate through the self-locking conical surfaces, the distance between the end faces, away from each other, of the two circular rings changes. The vibration suppression capability of the damper in practical application is improved, and errors generated during performance detection of the damper are reduced.
本申请涉及工程结构减震技术领域，尤其涉及一种无间隙黏滞流体阻尼器及其安装方法，该无间隙黏滞流体阻尼器，包括缸筒、压紧螺母、杆端连接耳环、缸端连接耳环、无隙销轴以及沿缸筒轴向依次设置在缸筒内的杆端导向套、杆端活塞杆、活塞、缸端活塞杆、缸端导向套，杆端活塞杆、缸端活塞杆与活塞之间螺纹连接，上述的螺纹连接处均设置有小锁紧垫片，小锁紧垫片包括两个同轴转动配合的圆环，圆环相互靠近的侧壁上均设置自锁锥面，通过自锁锥面两个圆环同轴相对转动时，两个圆环相互远离的端面之间的距离发生变化，本申请通过减小阻尼器的轴向间隙，提高了阻尼器在实际应用中对震动的抑制能力，减小了阻尼器在性能检测时产生的误差。
