Double-outlet-rod type friction damper
The invention discloses a double-outlet-rod type friction damper. The friction damper is characterized in that a sliding shaft is movably arranged in an outer sleeve in a penetrating mode, the two ends of the sliding shaft extend out of the two ends of the outer sleeve, and the surface of the sliding shaft is a friction face with a certain friction system; a plurality of friction sliding blocks are distributed in the circumferential direction of the sliding shaft, and the friction base face of each friction sliding block is in sliding friction fit with the surface of the sliding shaft; extrusion rings sleeve the two ends of a plurality of friction sliding blocks distributed in the circumferential direction of the sliding shaft, the inner surface of each extrusion ring is in synchronous contact fit with the arc slopes on the plurality of friction sliding blocks, and the outer surface of each extrusion ring is in contact fit with the inner wall of the outer sleeve; and limiting springs are arranged relative to the extrusion rings, and pre-pressure facing the friction sliding blocks is formed on the extrusion rings. The friction damper capable of sliding bidirectionally can replace aconventional friction damper, and can be used in flexible connection, such as a cable of a cable structure.
本发明公开了一种双出杆式摩擦阻尼器，其中的滑动轴可移动的穿设在外套筒中，其两端从外套筒两端伸出，滑动轴的表面为具有一定摩擦系统的摩擦面；若干摩擦滑块沿滑动轴周向分布，每个摩擦滑块的摩擦基面与滑动轴表面形成滑动摩擦配合；挤压环分别套设在沿滑动轴周向分布的若干摩擦滑块的两端，每个挤压环的内表面与若干摩擦滑块上的圆弧斜面同步接触配合，外表面与外套筒的内壁接触配合；限位弹簧相对于挤压环设置，对挤压环形成面向摩擦滑块的预压力。本可双向滑动的摩擦阻尼器，可替代常规摩擦阻尼器，亦可用于柔性连接中，如索结构的拉索中。
