    • PROBLEM TO BE SOLVED: To provide a fastener assembly achieving a desired clamping force with predictable consistency and considerably less affected by frictional variation than conventional fasteners.
      SOLUTION: A torquing member of the fastener assembly has annular threads and an annular bearing surface extending at one end of the member. A clamping pressure member of the fastener assembly has an annular bearing surface extending at one end and an annular clamping surface extending at an opposite end. The annular bearing surface of the torquing member includes a first series of helically inclined surface segments having substantially the same pitch as the threads and a second series of helically inclined surface segments having the same pitch axis as the threads but a pitch equal to or greater than that of the threads, with an opposite incline. The annular bearing surface on the clamping pressure member includes a first series of helically inclined surface segments having the same pitch as the threads and a second series of helically inclined surface segments having the same pitch and direction as the equal or greater pitch.

    • 要解决的问题:提供一种紧固件组件,其实现具有可预测的一致性并且比常规紧固件更少受摩擦变化影响的期望的夹紧力。 解决方案:紧固件组件的扭力构件具有环形螺纹和在构件的一端延伸的环形支承表面。 紧固件组件的夹紧压力构件具有在一端延伸的环形支承表面和在相对端延伸的环形夹紧表面。 扭转构件的环形支承表面包括具有与螺纹基本相同的螺距的第一系列螺旋形倾斜表面段和具有与螺纹相同的俯仰轴的第二系列的螺旋形倾斜表面段,但是等于或大于 线程相对倾斜。 夹持压力构件上的环形支承表面包括具有与螺纹相同的间距的第一系列螺旋形倾斜表面段和具有与等于或更大间距相同的螺距和方向的第二系列螺旋形倾斜表面段。 版权所有(C)2010,JPO&INPIT
