Abstract

一种防松动螺纹件，包括内螺纹件（1）与外螺纹件（2）。内螺纹件（1）的内孔中设置有圆柱内螺纹（3），外螺纹件（2）的螺杆上设置有圆柱外螺纹（4），外螺纹（4）或内螺纹（3）的牙底有与外螺纹（4）或内螺纹（3）的纵向中轴线（5）呈夹角α或夹角β的楔形斜面（6），tanα或tanβ小于楔形斜面（6）与内螺纹（3）或外螺纹（4）的接触面之间的动摩擦因数，内、外螺纹件之间相互旋合拧紧后，内螺纹（3）或外螺纹（4）的表面与楔形斜面（6）之间是相互紧密接触的结构，也就是横向锁止的结构，只要预紧力能够使内螺纹或外螺纹的表面与楔形斜面之间相互紧密接触，就能够实现各种材质螺纹表面的圆柱螺纹件联接副的有效防松。
