Rotary bridge vibration reduction system
The invention discloses a rotary bridge vibration reduction system. The rotary bridge vibration reduction system comprises a base, a top disc, a gear assembly, an outer supporting ring and a friction ring assembly. The top tray is used for connecting bridges. The gear assembly comprises a gear shaft, a bevel gear and a straight gear. The gear shaft is rotationally installed on the base. The bevel gear drives the gear shaft to rotate, and the straight gear rotates along with the gear shaft. And the outer support ring is fixedly connected with the top tray. A bevel gear groove matched with the bevel gear in shape is formed in the lower end face of the outer supporting ring so that the bevel gear can be driven to rotate when the outer supporting ring moves up and down. The friction ring assembly comprises an inner friction ring, an outer friction ring, an inner gear and an outer gear. The inner friction ring is located on the inner side of the outer supporting ring, the outer friction ring is located on the outer side of the outer supporting ring, and the inner friction ring and the outer friction ring are both in sliding contact with the base. The inner gear and the outer gear are both meshed with the straight gear. The inner gear is fixed to the outer friction ring, and the outer gear is fixed to the inner friction ring. Compared with the prior art, the invention provides a new bridge vibration energy dissipation idea.
本发明公开了一种旋转式桥梁减振系统，包括底座、顶盘、齿轮组件、外支撑环和摩擦环组件。顶盘用于连接桥梁。齿轮组件包括齿轮轴、斜齿轮和直齿轮。齿轮轴转动安装于底座上。斜齿轮带动齿轮轴旋转，直齿轮随齿轮轴旋转。外支撑环与顶盘固定相连。外支撑环的下端面设有与斜齿轮外形匹配的斜齿轮槽，以在外支撑环上下运动时驱动斜齿轮旋转。摩擦环组件包括内摩擦环、外摩擦环、内齿轮和外齿轮。内摩擦环位于外支撑环的内侧，外摩擦环位于外支撑环的外侧，内摩擦环、外摩擦环均与底座滑动接触。内齿轮、外齿轮均与直齿轮啮合。内齿轮固定于外摩擦环上，外齿轮固定于内摩擦环上。相比于现有技术，本发明提供了一种新的桥梁振动能量耗散思路。
