| 摘 要： | 某系列飞机用自锁螺母锁紧力矩不稳定原因分析。自锁螺母采用滚压收口可使螺母收口部侠的螺纹孔由圆表变成曲率变化均匀的对称的椭圆形，螺距沿螺纹孔轴向增大，造成与螺栓干涉配合，可获得比较稳定的锁紧力矩。

| Abstract: | The Various things accounting for unstable locking torque of the self-locking nuts used the X mode series aircraft is analyzed. The principle on the reducing of self-locking nuts and the manufacting equipment are decribed. The reducing by rolling makes a hole for tapping in the nut reducing portion from circular shape to symmetrical elliptical shape whose curvature varies evenly and makes the pitch increased axially along the screw thread, causing a interference fit, and there by resulting in a relatively stable locking torque |
