圆锥管螺纹分牙形角为55°(威氏)和60°(布氏)的两种,二者的锥度都为1:16,斜角φ=1°47′24″。锥形螺纹可分为:1牙型角平分线垂直于圆锥母线,2牙型角平分线垂直于圆锥中心线的两种。第二种采用最多。本文介绍第二种圆锥管螺纹塞规的测量——半角的测量;螺距的测量;中径的测量;中径锥度的测量。
Conical pipe threads are 55 ° (Wechsler) and 60 ° (Brinell), both with a taper of 1:16 and a bevel of φ = 1 ° 47’24 ". Divided into: 1 dental angle bisector vertical to the conical bus, 2 dental angle bisector perpendicular to the centerline of the cone two kinds. The second most used. This article describes the second conical pipe thread plug gauge measurement - half-angle Measurement of pitch; measurement of pitch; measurement of pitch taper.
