Pinion and rack type tuning inertial damper
The invention relates to the technical field of building damping, and discloses a gear and rack type tuning inertial damper. The device comprises a sleeve, a closed damping cavity is formed in the sleeve and filled with viscous damping liquid, a gear and rack transmission structure is installed in the damping cavity, an inertia element is fixed to the gear and rack transmission structure, and the gear and rack transmission structure is connected with a main body structure and a spring element outside the damping cavity. The gear and rack transmission structure can convert axial movement into circumferential movement and drive the inertia element to rotate at the same time, and horizontal force transmission can be achieved between the gear and rack transmission structure and the spring element. The axial speed of the two ends of the damper is converted into the angular speed of movement of the mass block through the gear and the rack, and the convex plates on the side faces of the mass block are used for stirring viscous damping liquid in the rotating process to dissipate energy. Compared with a ball screw type tuning inertial damper, the damper is simple in structure, easy to machine and excellent in vibration reduction capacity.
本发明涉及建筑减震技术领域，且公开了一种齿轮齿条式调谐惯质阻尼器。本发明包括套筒，所述套筒内设有封闭的阻尼腔且填满粘滞阻尼液，所述阻尼腔内安装有齿轮齿条传动结构，所述齿轮齿条传动结构固定有惯质元件，并且连接阻尼腔外的主体结构和弹簧元件，所述齿轮齿条传动结构可以将轴向运动转化为周向运动，同时带动惯质元件转动，并能和弹簧元件之间实现力的水平传递。本发明依靠齿轮齿条将阻尼器两端的轴向速度转换成质量块运动的角速度，并且利用质量块侧面的凸板在转动过程中搅拌黏滞阻尼液进行耗能。相比滚珠丝杠式调谐惯质阻尼器，该阻尼器构造简单，易于加工，且具有优异的减振能力。
