E1 = pitch diameter at the large end of the internal thread and at the gaging notch; L1 = length of hand-tight or normal engagement between external and internal thread; L2 = basic length of effective external taper thread; D = outside diameter of pipe; p = pitch = 1 ÷ number of ...
The invention relates to a spherical inner thread pitch diameter measuring method. According to the method, a spherical inner thread pitch diameter calculation formula is established through analyzing ball screw assembly structure principles, and target sizes can be obtained through a size conversion ...
