一、前言球转子式隔离机构具有体积小、结构简单、加工方便等优点,目前在国内航炮引信、高炮引信中已得到较广泛的应用。但由于设计和制造等各方面原因,球转子的球心和重心不可能完全重合,也不可能在弹轴上。因此,球转子转正后,它的惯性主轴与弹轴之间有一夹 I. Introduction Ball rotor isolation mechanism has the advantages of small size, simple structure, convenient processing and so on. At present, it has been widely used in domestic aviation fuze and anti-aircraft guns. However, due to various factors such as design and manufacture, it is impossible for the spherical center of gravity and the center of gravity of the ball rotor to completely coincide with each other, nor can it be on the elastic shaft. Therefore, after the rotation of the ball rotor, there is a clip between its principal axis of inertia and the shaft
