机上设备上的螺纹非我锁紧螺纹和传动螺纹,先来分享一下锁紧螺纹内我个人比较懵的英制螺纹
先说一下我的懵点(老师傅们采用的不是标准,采用的是约定成俗的习俗.而每个区域货行业的习俗可能都不相同,所以不具有宽泛>性.):

  1. 老师傅们口中的说的英制螺纹一般是国内比较常见的英制55度但有可能美制60度的.
  2. 好了确定完英制55度后,老师傅们说的G螺纹有可能是说的是用的比较多的PT ZG或者RC
  3. 从RC引申出了新老国标的问题,公称直径 DN20、6分、3/4 我是懵的一圈?

好了牢骚完了说正题吧!归纳一下吧,个人从标准手册归纳总结.非官方.

我去markdown果然不适合表格,累的手疼. 本来打算一口气整理一下,改天再整理少用的非锥度对吧!
