Variable friction energy consumption self-resetting rotating joint
The invention relates to a variable friction energy dissipation self-resetting rotating joint which comprises a bracket. The rotating frame is rotationally connected with the bracket through a rotating shaft, and the rotating shaft is further provided with a gear coaxially connected with the rotating shaft; the two cover plates are respectively positioned above and below the rotating shaft, and racks meshed with the gears are also arranged on the cover plates; two ends of the self-resetting device are respectively connected with the bracket and the cover plate; and two opposite staggered moving ends of the variable friction energy consumption device are respectively connected with the two cover plates. The problems that an existing self-resetting node cannot meet different requirements of a structure for energy dissipation capacity and rigidity under the action of earthquakes of different levels, or cannot achieve adjustable resetting force, or due to the fact that the rotating angle of the node is small, the energy dissipation capacity and the resetting capacity are insufficient can be solved.
本发明涉及一种变摩擦耗能自复位旋转节点，包括：托架；通过转动轴与所述托架转动连接的转动架，在所述转动轴上还与其同轴连接的齿轮；分别位于所述转动轴上下方的两块盖板，在盖板上还设有与所述齿轮啮合的齿条；自复位装置，其两端分别连接所述托架与盖板；以及变摩擦耗能装置，其两个相对错位移动端分别连接两块盖板。本发明可以解决现有自复位节点无法满足结构在不同级别地震作用下对于耗能能力和刚度具有不同的需求、或无法实现可调节的复位力，或由于节点转动角度较小，存在耗能能力和复位能力不足等问题。
