Abstract

Assuming that the deformation of the threads of the screw, nut and locknut are caused mainly by the contact flexibility of their working surface, the load distribution along the threads of the screw is studied. It is found that if the locknut is tightened with a force equal to half the tightening force of the nut, then the loads on the first turns of the nut and locknut will become the same, amounting to approximately half the load on the most loaded turn of the screw tightened without a locknut.

锁紧螺母对拧紧螺纹连接螺杆螺纹上载荷分布的影响

摘要假定螺钉、螺母和锁紧螺母的螺纹变形主要由其工作面的接触弹性引起，研究了螺钉螺纹上的载荷分布。研究发现，如果锁紧螺母的拧紧力等于螺母拧紧力的一半，那么螺母和锁紧螺母前几圈的载荷将变得相同，大约相当于无锁紧螺母拧紧螺钉时载荷最大圈的一半。
