THM液压螺母工作原理.doc

THM液压螺母工作原理 THM液压螺母是一种先进的螺栓装配方法，特别适用于狭窄空间和重负荷振动机械紧固，液压螺母的工作原理是利用液压油缸直接对螺栓施加外力，使被施加力的螺栓在其弹性变形区内被拉长，螺栓拉长后旋紧液压螺母上的锁圈，这样螺栓就会被锁圈锁止在拉长的位置上。液压缸位于螺栓中轴线的位置，用于对螺栓进行轴向拉伸，实现螺栓需要的拉伸量。而正是螺栓的这种拉伸量决定了螺栓紧固所需的夹紧力。当液压螺母被加压后，螺栓受到拉伸，同时液压螺母和结合面紧贴。从而将螺栓的轴向形变锁住，也就是将剩余螺栓载荷锁在螺母里。很多连接面之间都配有密封垫。密封垫只有在连接面被压紧时才起作用，因此连接面始终保持被夹紧的状态就显得尤其重要了。对螺栓施加的载荷与液压缸中的油压成正比关系，这样的设计能够非常精确地留住有效载荷。由于载荷直接施加在螺栓上，且所有作用力都用于螺栓拉长，因此载荷产生所需的空间可以达到最小。 安装 拉伸 锁紧THM液压螺母特点拉伸方式不受螺栓润滑效果和螺纹摩擦大小的影响，可以得到更为精确的螺栓载荷。可对多个螺栓进行同步拉伸，使整圈螺栓受力均匀，得到均衡的载荷。由于采用最先进的超高压技术，可以在很小的空间内完成螺栓的锁紧。拉伸方式对螺栓进行紧固得到的剩余载荷和有效载荷要比力矩方式更大，拉伸方式更适用于紧固精度要求较高的接合应用，它能使连接面受力均匀地实现接合，真正地防止泄漏。THM系列液压螺母结构爱普THM液压螺母根据不同的使用分厚型和薄型、高压和超高压、顶环锁紧和底环锁紧。THM液压螺母主要由油缸、活塞和锁圈组成，接油口有顶置和侧入设计。
