（1）**螺栓：強螺栓，使回用日益普遍，主要用答在一些比如戶外工程，風電或者具有能動性的機械上，抗拉強度比較大，**螺栓一般用于長久連接。 </p> <p> （2）普通螺栓，高用在一些小型機械，比如渦輪機上就可以，主要是看應用環(huán)境和運作方式。 </p> <p> 2，**螺栓和普通螺栓常用等級： </p> <p> （1）常用8.8s和10.9s兩個強度等級，其中10.9級居多。 </p> <p> （2）普通螺栓強度等級要低，一般為4.4級、4.8級、5.6級和8.8級。 </p> <p> <br /> 株洲**度螺栓螺栓和螺柱有什么區(qū)別？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="株洲**度螺栓,螺栓"

螺栓是一頭帶有螺栓頭，通常為六角形、外圓柱內(nèi)六角形、或者沉頭帶有一字型或十字型槽的專螺栓頭，另屬一端全段或者部分長度上帶有螺紋的緊固零件，緊固時只有帶螺紋的一端需要配螺母來實現(xiàn)緊固；螺柱又叫雙頭螺柱，結構是兩端都帶有螺紋，使用時需要先將一端擰緊到固定的零件上，然后放上緊固件，再在另一端緊固螺母來實現(xiàn)緊固作用。機械制圖中圖片非常清楚。 </p> <p>

</p><p> 化學螺栓和膨脹螺栓的區(qū)別： </p> <p> 1、化學螺栓 </p> <p> 化學螺栓由化學膠管、螺內(nèi)桿、墊圈容及螺母組成。螺桿、墊圈、螺母(六角)一般有鍍鋅鋼和不銹鋼兩種(也可按要求熱鍍鋅)?；瘜W膠管(或用塑料包裝的藥劑管)含有反應樹脂、固化劑和石英顆粒。 </p> <p> 化學螺栓是靠與混凝土之間的握裹力和機械咬合力共同作用來抗拔和螺栓本身來抗剪，主要用在新舊結構的連接處，各項力學指標計算時要根據(jù)生產(chǎn)廠家提供的資料來進行。 </p> <p> 2、膨脹螺栓 </p> <p> 膨脹螺栓，是將管路支/吊/托架或設備固定在墻上、樓板上、柱上所用的一種特殊螺紋連接件。 </p> <p> <br /> 螺栓強度等級如何劃分？</p><div

style="text-indent:25px">預緊力的大小與螺栓的擰緊力矩、螺栓與螺母之間的摩擦力、螺母與被聯(lián)接件之間的摩擦力有關,因此跟潤滑情況有關系，至于公式有很多，大部分都是經(jīng)驗公式之類的沒有太大的關系。非常簡單，螺栓預緊力=夾緊力+外部載荷當外部載荷為零時，夾緊力就是螺栓預緊力，當工件收到張力時，也就是有外部載荷，螺栓只要沒有發(fā)生形變，那么螺栓預緊力就是不變的，但是夾緊力在變小當外部載荷大于螺栓預緊力時，螺栓被再次拉伸，此時工件分離，沒有任何夾緊力五分送來。螺栓：大拉力=10000N，小拉力2000N 被連接件：小壓力=10000N，大壓力18000N 題目是求工作中螺栓及被連接件所受（力）的大與小值，只算內(nèi)力的話，沒有用。**度螺栓摩擦型和承壓型連接有什么區(qū)別?河南美標螺栓</p><p style="text-indent:25px">螺栓的屈服強度有多大？株洲**度螺栓</p><p> 鋼結構連接用以螺栓性能等級分3.6、4.6、4.8、5.6、6.8、8.8、9.8、10.9、12.9等10余個等級， </p> <p> <br /> </p> <p> 普通螺栓連接中,螺栓與孔間有間隙.其優(yōu)點是加工方便,成本低,所以應用范圍廣. </p> <p> 鉸制孔用螺栓中,其螺桿外徑與螺栓孔(由高精度鉸刀加工而成)的內(nèi)徑具有同一基本尺寸,并常采用過渡配合.它適用于承受垂直與螺栓軸線的橫向載荷. </p> <p> <br /> </p> <p> 普通螺栓連接的構造要求： </p> <p> (1)螺栓的直徑 </p> <p> 在同一結構連接中，無論是臨時安裝螺栓還是長久螺栓，為了便于制造，宜用同一種直徑的螺栓孔d。螺栓直徑d的選擇根據(jù)連接件的尺寸和受力大小而定，可參照表9-1螺栓的有效面積，按螺栓結構形式和受力大小進行計算。常用的標準螺栓直徑是M16、M18、M20、M22、M24。 </p> <p> (2)螺栓的排列及間距 </p> <p> 螺栓的排列及間距可分為并列排列與錯位排列兩種，如圖9-2所示。其排列原則如下： </p> <p> 受力要求螺栓孔(do)的小端距(沿受力方向)為2do，以免板端被剪掉；螺栓孔的小邊距(垂直于受力方向)為1．5Jo(切割邊)或1．2do(軋成邊)。在型鋼上，螺栓應排列在型鋼準線上。中間螺孔的小間距(栓距和線距)為3do，否則螺孔周圍應力集中的相互影響較大，且對鋼板的截面削弱過多，從而降低其承載能力。
