There are some locking pins equidistantly distributed around the circumference of the tooth-web lock nut, which can be locked onto the shaft after the nut is pressed down with the fastening screw. The end faces of each locking pin are machined to match the shaft threads. The drilling axis of the locking pin and the fastening screw is parallel to the loading surface of the shaft thread. When tightening to the recommended torque, the locking screw provides sufficient friction between the end of the locking pin and the unloaded threaded side to prevent the nut from loosening under normal operating conditions. The advantages of abdominal locking nuts are:

1. No keyway required

2. Reusable

3. Suitable for frequent disassembly.

4. Since the locking pin is pressed against the unloaded side of the shaft thread, it will not be subjected to any applied load on the nut.

牙腹锁紧螺母圆周上有等距分布的一些锁定销,可以用紧定螺钉压紧螺母后，锁定到轴上。每个锁定销的端面都经过加工，以便匹配轴螺纹。锁定销和紧定螺钉的钻孔轴线平行于轴螺纹的受载面。当拧紧到推荐扭矩时，锁定螺钉在锁紧销的末端和不受载的螺纹侧之间提供足够的摩擦，以防止螺母在正常运行条件下松动。、牙腹锁紧螺母的优势有：
1、无需键槽
2、可重复使用
3、适用于频繁拆卸场合。
4、由于锁定销紧压在轴螺纹不受载一侧，因此不会受到施加在螺母上的任何应用载荷。
