**度螺栓是用特制的扳手上緊螺帽，使螺栓產(chǎn)生巨大而又受控制的預拉力，通過螺帽和墊板，對被連接件也產(chǎn)生了同樣大小的預壓力。在預壓力作用下，沿被連接件表面就會產(chǎn)生較大的摩擦力，顯然，只要軸力小于此摩擦力，構(gòu)件便不會滑移，連接就不會受到破壞，這就是**度螺栓連接的原理。 **度螺栓連接是靠連接件接觸面間的摩擦力來阻止其相互滑移的，為使接觸面有足夠的摩擦力，就必須提高構(gòu)件的夾緊力和增大構(gòu)件接觸面的摩擦系數(shù)。</p><p

style="text-indent:25px">螺栓在日常生活當中和工業(yè)生產(chǎn)制造當中，是少不了的，螺栓也被稱為工業(yè)之米。可見螺栓的運用之普遍。螺栓的運用范圍有：電子產(chǎn)品，機械產(chǎn)品，數(shù)碼產(chǎn)品，電力設(shè)備，機電機械產(chǎn)品。船舶，車輛，水利工程，甚至化學實驗上也有用到螺栓。反正是超多地方都有用到螺栓的。特如數(shù)碼產(chǎn)品上面用到的精密螺栓。受力方式：普通的和有鉸制孔用的。普通的主要承載軸向的受力，也可以承載要求不高的橫向受力。鉸制孔用的螺栓要和孔的尺寸配合，用在受橫向力時。采購螺栓一定要去正規(guī)的廠家。法蘭螺栓生產(chǎn)廠家</p><p style="text-indent:25px">沉頭螺絲又被稱為平機螺絲。法蘭螺栓生產(chǎn)廠家</p><p style="text-indent:25px">普通螺栓按照制作精度可分為A、B、C三個等級，A、B級為精制螺栓，C級為粗制螺栓。對于鋼結(jié)構(gòu)用連接螺栓，除特別注明外，一般為普通粗制C級螺栓。不同的級次加工的方法存在差異，通常對應加工方式如下： ①A、B級螺栓的栓桿由車床加工而成，表面光滑，尺寸精確，其材料性能等級為8.8級，制作安裝復雜，價格較高，很少采用; ②C級螺栓用未加工的圓鋼制成，尺寸不夠精確，其材料性能等級為4.6級或4.8級?？辜暨B接時變形大，但安裝方便，生產(chǎn)成本低，多用于抗拉連接或安裝時的臨時固定。法蘭螺栓生產(chǎn)廠家</p><p
