Single-rod planetary ball screw double-screw transmission type damper
The invention belongs to the technical field of vibration reduction and isolation, and particularly relates to a single-rod planetary ball screw double-screw transmission type damper which comprises a left spherical hinge seat, a fixed outer cup, a rotary inner cup, a planetary gear, a central gear, a planetary screw, a central screw, a flange plate, a piston rod, a damping spiral spring and a right spherical hinge seat. And the left spherical hinge seat, the fixed outer cup, the central gear, the central screw rod and the flange plate are all fixed on the piston rod. Permanent magnets are arranged on the flange plate at intervals. The end of the piston rod is of an annular structure, a damping spring is arranged on the outer side face, and the inner side face is matched with the right spherical hinge seat rod to play a guiding role. The piston rod axially moves to drive the central screw to move, so that the planetary screw moves, the rotary inner cup is driven to rotate, magnetic induction lines generated by the permanent magnet are cut, and eddy current energy consumption is generated. Compared with the prior art, the device has the advantages of no damage after an earthquake, convenience in installation, small installation size, automatic structure recovery, no liquid leakage, low cost, no maintenance, stable performance and the like.
本发明属于减隔振技术领域，特别涉及一种单出杆行星滚珠丝杆双螺旋传动式阻尼器，包括：左球铰座、固定外杯、旋转内杯、行星齿轮、中心齿轮、行星螺杆、中心螺杆、法兰盘、活塞杆、阻尼螺旋弹簧和右球铰座。左球铰座、固定外杯、中心齿轮、中心螺杆、法兰盘均固定于活塞杆上。法兰盘上间隔布局有永磁体。活塞杆端部为环状结构，外侧面设置有阻尼弹簧，内侧面配合右球铰座杆起导向作用。活塞杆轴向运动会带动中心螺杆运动，使行星螺杆运动，从而带动旋转内杯转动，切割永磁体产生的磁感线，产生电涡流耗能。与现有技术相比，本发明具有震后无损伤、安装方便、安装体积小、结构可自动恢复、无液体渗漏、成本低、免维护、性能稳定等优点。
