Working principle of the lock nut is to use thefriction between the nut and the bolt for self-locking. However, in the case ofdynamic load, this self-locking will be reduced, so it is necessary to take someanti-loosening measures to ensure the reliability of the nut. Precision locknutwith locking pin is higher than the general locking nut in terms of threadaccuracy grade and material. The anti-loosening method is to reduce the gapbetween the nut thread and the shaft thread through a device to generate enoughfriction to achieve the purpose of preventingbacklash. The general working principleof the lock nut is to use the friction between the nut and the bolt forself-locking.锁紧螺母的一般工作原理是利用螺母与螺栓之间的摩擦力进行自锁。The general working principle of lock nuts is to use the friction betweenthe nut and the bolt to self-lock.锁紧螺母的一般工作原理是利用螺母与螺栓之间的摩擦力自锁。无法加载全部结果

但在动载荷的情况下，这种自锁性会降低，所以需要采取一些防松措施来保证螺母的可靠性。
