The invention belongs to the technical field of aircrafts, and particularly relates to an aviation control steel cable abrasion improving structure which comprises a pulley assembly and a plurality of first guide pulleys, and a control steel cable sequentially crosses over the first guide pulleys; the pulley assembly comprises a second guide pulley, a supporting rod, an adjusting device and a mounting base, one end of the supporting rod is arranged on the mounting base, the second guide pulley is rotationally arranged at the other end of the supporting rod, and the adjusting device is used for adjusting the distance between the second guide pulley and the mounting base; at least one pulley assembly is arranged between every two adjacent first guide pulleys, and the second guide pulley and the first guide pulleys are located on the same side or different sides of the control steel cable. The aviation control steel cable abrasion improving structure has the beneficial effects that at least one pulley assembly is additionally arranged between the two first guide pulleys, so that the span of the aviation control steel cable is reduced, and the conditions of high-frequency vibration, small axial rigidity, easy change of force transfer direction, looseness and abrasion of the aviation control steel cable are effectively improved.
本发明属于航空器技术领域,尤其涉及一种航空操纵钢索改善磨损的结构,包括滑轮组件和若干第一导向滑轮,操纵钢索依次跨过若干第一导向滑轮;滑轮组件包括第二导向滑轮、支撑杆、调节装置和安装底座,支撑杆的一端设在安装底座上,第二导向滑轮转动设在支撑杆的另一端,调节装置用于调节第二导向滑轮至安装底座的距离;相邻第一导向滑轮之间设有至少一组滑轮组件,且第二导向滑轮与第一导向滑轮位于操纵钢索的同侧或异侧。有益效果:本发明的航空操纵钢索改善磨损的结构,通过在两个第一导向滑轮之间增加至少一组滑轮组件,减少了航空操纵钢索的跨度,有效改善航空操纵钢索的高频振动、轴向刚度小、传力方向易改变、松弛和磨损情况。
