随着行波管工艺水平的发展,所要求的螺旋线变得更加复杂。不易实现的增益指标和对电子转换效率要求的提高,都迫使我们回过头来研究绕制技术。用车床绕制等螺距螺旋线的传统方法,再加上一个凸轴随动机械装置就可以绕制变螺距螺旋线。由于频率和功率电平越高,就要求更小更难绕制的螺旋线,对精度和变化的要求也提高了。 With the development of traveling wave tube technology, the required helix becomes more complicated. Difficult to achieve gain targets and requirements for the efficiency of electronic conversion, have forced us to go back and study winding technology. The traditional method of turning helical pitch helical thread with a lathe and the like, together with a convex axis follower mechanical device, can change the helical pitch of the helical thread. Due to the higher frequency and power level, smaller and harder coils are required, increasing the need for precision and variation.
