防松垫圈 ? 防松原理
防松垫圈独特的内侧斜齿面倾斜角度α大于螺栓螺纹倾斜角度 β。装配时，内侧斜齿面是相对的，垫圈外侧放射状的凸纹面（外滚花齿面）的摩擦系数要比内侧斜齿面的摩擦系数大，且与两端接触面成咬合状态。当连接件受到振动，并使螺栓发生松动趋势时，仅仅允许两片垫圈内侧斜齿间相对错动，产生抬升张力。独特的齿牙系统利用张力在紧固的连接处产生一个很高的抵抗力来经受振动力，从而达到 100% 的防松效果。
防松垫圈·使用优势
确保在强震动下仍然保持连接件的夹紧力，优于依靠摩擦力来制琐的紧固件；
防止因震动引起的螺栓松动，不再发生由于紧固件松动而引起的相关问题；
不需要特殊的安装工作，容易安装和拆卸；
锁紧功能不受润滑影响；
温度有变化也不会使连接件松动；
具有耐久性；
可重复使用；
这个系统可以用高或低的预负载力锁紧固定元件；
垫圈两个大的斜齿面相对胶合成对，目的是便于安装这一防松系统。
