徑。螺距，相鄰牙在中徑線上對(duì)應(yīng)兩點(diǎn)間的軸向間隔。導(dǎo)程，同一螺旋線上相鄰牙在中徑線上對(duì)應(yīng)兩點(diǎn)間的軸向間隔。牙型角，螺紋牙型上相鄰兩牙側(cè)間的夾角。螺紋升角，中徑圓柱上螺旋線的切線與垂直于螺紋軸線的平面之間的夾角。工作高度，兩相配合螺紋牙型上相互重合部分在垂直于螺紋軸線方向上的間隔等。螺紋的公稱直徑除管螺紋以管子內(nèi)徑為公稱直徑外，其余都以外徑為公稱直徑。螺紋已標(biāo)準(zhǔn)化，有米制（公制）和英制兩種。國(guó)際標(biāo)準(zhǔn)采用米制，中國(guó)也采用米制。圓柱螺紋中，三角形螺紋自鎖性能好。它分粗牙和細(xì)牙兩種，一般聯(lián)接多用粗牙螺紋。細(xì)牙的螺距小，升角小，自鎖性能更好，常用于細(xì)小零件薄壁管中，有振動(dòng)或變載荷的聯(lián)接，以及微調(diào)裝置等。管螺紋用于管件緊密聯(lián)接。矩形螺紋效率高，但因不易磨制，且內(nèi)外螺紋旋合定心較難，故常為梯形螺紋所代替。鋸齒形螺紋牙的工作邊接近矩形直邊，多用于承受單向軸向力。圓錐螺紋的牙型為三角形，主要靠牙的變形來保證螺紋副的緊密性，多用于管件。六、我國(guó)常用螺紋標(biāo)準(zhǔn)種別標(biāo)準(zhǔn)名稱標(biāo)準(zhǔn)號(hào)與國(guó)際標(biāo)準(zhǔn)的關(guān)系普通螺紋普通螺紋基本牙型GB/T1921981與ISO68等效普通螺紋直徑與螺距系列GB/T1931981與ISO261等效普通螺紋基本尺寸GB/T19
