表中数值按下列公式计算,数值圆整到小数点后第二位:

D =D-10 H /8; D2

= D — 6 H /8

d1

= d — 10 H /8; d2

= d-6 H /8

H=J? P/2 = 0.866025404P

D—内螺纹大径;D1—内螺纹小径;D2—内螺纹中径;

d—外螺纹大径;d1—外螺纹小径;d2—外螺纹中径;

P一螺距; H一原始三角形高度

注:1、直径优先选用第一系列,其次第二系列,第三系列尽可能不用。

2、带括号的螺距尽可能不用。

3、M14X1.25仅用于火花塞,M35X1.5仅用于滚动轴承锁紧螺母。

4、对直径150〜600mm的螺纹,需要使用螺距大于6mm的螺纹时,应优先选用8mm的螺距。

表中数值按下列公式计算,数值圆整到小数点后第二位:

D =D-10 H /8; D2

= D — 6 H /8

d1

= d — 10 H /8; d2

= d-6 H /8

H=J? P/2 = 0.866025404P

D—内螺纹大径;D1—内螺纹小径;D2—内螺纹中径;

d—外螺纹大径;d1—外螺纹小径;d2—外螺纹中径;

P一螺距; H一原始三角形高度

注:1、直径优先选用第一系列,其次第二系列,第三系列尽可能不用。

2、带括号的螺距尽可能不用。

3、M14X1.25仅用于火花塞,M35X1.5仅用于滚动轴承锁紧螺母。

4、对直径150〜600mm的螺纹,需要使用螺距大于6mm的螺纹时,应优先选用8mm的螺距。
