  产品简介
 

  英国人约瑟夫.惠特沃斯(JOSEPH WHITWORTH)最早提出了惠氏螺纹标准,以后出现的世界各国螺纹标准基本上都是参照惠氏螺纹标准技术体系而制订的。
  为了在螺纹技术上垄断,惠特沃斯特意把螺纹牙型的牙顶和牙底设计为圆弧状,虽然有很多其它公司也掌握了螺纹加工技术,但只有惠特沃斯所在的公司能够加工带有圆弧牙顶和牙底的螺纹。在一个时期内惠特沃斯所在的公司确实在螺纹市场上处于垄断地位,直到美制统一螺纹的出现才打破了这种垄断,由于美制统一螺纹容易加工,很快挤占了英制惠氏螺纹市场。  
     英制惠氏螺纹牙型图

  于今,英制惠氏螺纹在进出口产品和一些老设备的维修上还用到。
  我公司应英制惠氏螺纹市场的需求配套有英制惠氏螺纹钢丝螺套供您选用,也可按您的要求设计制造。

英制惠氏螺纹钢丝螺套 
                英制惠氏螺纹钢丝螺套

  英制惠氏螺纹钢丝螺套的标记由钢丝螺套型号代号(FR SL)、公称直径、牙数、螺纹代号(B.S.W. B.S.F.)、公称长度组成。
  如,普通型钢丝螺、公称直径为1/8英寸、每英寸牙数为40牙、公称长度为1.5d的粗牙英制惠氏螺纹钢丝螺套标记为:
  FR 1/8″-40 B.S.W-1.5d
  再如,公称直径为3/16英寸、每英寸牙数为32牙、公称长度为1.5d的自锁型细牙英制惠氏螺纹钢丝螺套标记为:
  SL 3/4″-32.B.S.F.-1.5d
