Self-locking pre-pressing friction damper
The invention discloses a self-locking pre-pressing friction damper. The self-locking pre-pressing friction damper comprises a core plate, wherein friction pieces are arranged at two sides of the core plate; a restraining plate is arranged at the side, far away from the core plate, of each friction piece; a plurality of transverse long slotted holes are formed in the core plate in a penetrating mode; a first round hole is formed in each friction piece in a penetrating mode; a plurality of second round holes are formed in each restraining plate in a penetrating mode; the self-locking pre-pressing friction damper also comprises a plurality of screw bolts; each screw bolt is in threaded connection with a connecting screw nut and a restraining screw nut; restraining holes are formed in the edges of the second round holes in a mode of penetrating through the restraining plates; each restraining hole comprises a through hole far away from the core plate and an expansion hole being close to the core plate and having the inner diameter greater than that of the through hole; limiting holes are formed in each restraining screw nut and a nut of each screw bolt; a plurality of limiting nails are also comprised; each limiting nail comprises a limiting section and an expansion section; and the expansion section is connected with the limiting section and can be expanded under stress. After the product is produced, the screw nut cannot be loosened, the pre-pressure of the screw bolt cannot be lost, and the condition of energy dissipation capacity reduction of the damper is avoided.
本发明公开了一种自锁预压摩擦阻尼器，包括芯板，芯板的两侧均设置有摩擦片，每一摩擦片远离芯板的一侧均设置有约束板；贯穿芯板开设有多个横向的长槽孔，贯穿每一摩擦片均开设有第一圆孔，贯穿每一约束板均开设有多个第二圆孔；还包括多根螺栓，每一螺栓均螺纹连接有连接螺母及约束螺母；贯穿每一约束板均于第二圆孔的边缘开设有约束孔，每一约束孔均包括远离芯板的穿孔、靠近芯板且内径大于穿孔的膨胀孔，每一约束螺母及每一螺栓的螺帽均开设有限位孔；还包括多根限位钉，每一限位钉均包括限位段、与限位段连接且可受力膨胀的膨胀段。本发明的产品生产完成后不会出现螺母松动，螺栓预压力不会损失，不会出现阻尼器耗能能力下降的情况。
