Multi-gear transmission particle inerter damper
The invention discloses a multi-gear transmission particle inerter damper. A first metal shell and a nut are welded together, one end of a ball screw is inserted into the first metal shell through the nut, and the other end of the ball screw is inserted into a second metal shell through a bearing and welded together with a gear assembly. In the second metal shell, the gear assemblies are meshed, one end of a transmission rod is welded or connected with the gear assemblies through bolts, and the other end of the transmission rod is inserted into a third metal shell through a bearing. When the first metal shell and the second metal shell or the third metal shell generate relative displacement, the gear assemblies drive the transmission rod, a flywheel and particles to rotate, and friction and collision between the particles and the flywheel and between the particles and an elastic damping layer are caused. The damper has the advantages that the damper is simple in structure and convenient to mount, raw materials are affordable and easy to obtain and the like, has the characteristics of multiple inerter energy absorption, friction collision energy consumption, multi-frequency tuning, being able to drive big by small, variable direction and the like, and vibration between structures under the effects of wind loads, earthquakes, vehicle impact and the like can be effectively reduced.
本发明公开了一种多重齿轮传动颗粒惯容阻尼器，金属外壳一与螺母焊接在一起，滚珠丝杠一端通过螺母插入金属外壳一内，另一端通过轴承插入金属外壳二内，并与齿轮组件焊接在一起。金属外壳二内，齿轮组件相互啮合，传动杆件一端与齿轮组件焊接或螺栓连接，另一端通过轴承插入金属外壳三内。当金属外壳一与金属外壳二或金属外壳三发生相对位移时，齿轮组件带动传动杆件与飞轮、颗粒转动，并造成颗粒与飞轮和弹性阻尼层的摩擦与碰撞。本发明具有结构简单、安装方便以及原材料实惠易得等优点，兼具多重惯容吸能、摩擦碰撞耗能、多频调谐、以小带大、方向可变等特点，可有效减小风荷载、地震以及车辆冲击等作用下结构之间的振动。
