1、螺栓材質(zhì)公稱(chēng)抗拉強(qiáng)度達(dá)400MPa級(jí)； 2、螺栓材質(zhì)的屈強(qiáng)比值為0.6； 3、螺栓材質(zhì)的公稱(chēng)屈服強(qiáng)度達(dá)400×0.6=240MPa級(jí) 性能等級(jí)10.9級(jí)**度螺栓，其材料經(jīng)過(guò)熱處理后，能達(dá)到： 1、螺栓材質(zhì)公稱(chēng)抗拉強(qiáng)度達(dá)1000MPa級(jí)； 2、螺栓材質(zhì)的屈強(qiáng)比值為0.9； 3、螺栓材質(zhì)的公稱(chēng)屈服強(qiáng)度達(dá)1000×0.9=900MPa級(jí) 螺栓性能等級(jí)的含義是國(guó)際通用的標(biāo)準(zhǔn)，相同性能等級(jí)的螺栓，不管其材料和產(chǎn)地的區(qū)別，其性能是相同的，設(shè)計(jì)上只選用性能等級(jí)即可。強(qiáng)度等級(jí)所謂8.8級(jí)和10.9級(jí)是指螺栓的抗剪切應(yīng)力等級(jí)為8.8GPa和10.9GPa 10.9s的s

(2)每個(gè)螺栓一端不可墊兩個(gè)及兩個(gè)以上的墊圈，并且不可采用大螺母代替墊圈。螺栓擰緊后，外露螺紋不得少于兩扣。 </p> <p> <br /> </p> <p> (3)對(duì)于設(shè)計(jì)有要求防松動(dòng)的螺栓、錨固螺栓需采用有防松裝置的螺母（即雙螺母）或者彈簧墊圈，或者用人工方法采取防松措施（如將螺栓外露螺紋打毛）。 </p> <p> <br /> </p> <p> (4)對(duì)于承受動(dòng)荷載或重要部位的螺栓連接，需按照設(shè)計(jì)要求放置彈簧墊圈，彈簧墊圈應(yīng)設(shè)置在螺母一側(cè)。 </p> <p> <br /> </p> <p> (5)對(duì)于工字鋼、槽鋼類(lèi)型鋼應(yīng)盡可能使用斜墊圈，使得螺母和螺栓頭部的支承面垂直于螺桿。 </p> <p> <br /> </p> <p> (6)雙頭螺栓的軸心線(xiàn)應(yīng)與工件垂直，通常用角尺進(jìn)行檢驗(yàn)。 </p> <p> <br /> </p> <p> (7)裝配雙頭螺栓時(shí)，首先應(yīng)將螺紋和螺孔的接觸面清理干凈，然后再用手輕輕地把螺母擰到螺紋的終止處，如果遇到擰不進(jìn)的情況，不得用扳手強(qiáng)行擰緊，以避免損壞螺紋。 </p> <p> <br /> </p><p> 螺栓預(yù)緊力是在擰螺栓過(guò)程中擰緊力矩作用下的螺栓與被聯(lián)接件之間產(chǎn)生的沿螺栓軸心線(xiàn)方向的預(yù)緊力。對(duì)于一個(gè)特定的螺栓而言，其預(yù)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)接件之間的摩擦力相關(guān)。 </p> <p> <br /> </p> <p> 預(yù)緊力的大小，除了受限于螺釘材料的強(qiáng)度外，還受限于被聯(lián)接件的材料強(qiáng)度。當(dāng)內(nèi)外螺紋的材料相同時(shí)，只校核外螺紋強(qiáng)度即可。對(duì)于旋合長(zhǎng)度較短、非標(biāo)準(zhǔn)螺紋零件構(gòu)成的聯(lián)接、內(nèi)外螺紋材料的強(qiáng)度相差較大的受軸向載荷的螺紋聯(lián)接，還應(yīng)校核螺紋牙的強(qiáng)度。 </p> <p> <br /> </p> <p> 如某型產(chǎn)品彈性元件的固定，因螺釘連接的基材是壓鑄鋁合金YL113，其強(qiáng)度遠(yuǎn)低于質(zhì)量碳素結(jié)構(gòu)鋼20的強(qiáng)度，就應(yīng)校核鋁合金上螺紋牙型的強(qiáng)度，主要是螺紋材料的剪應(yīng)力及彎應(yīng)力。 </p> <p> <br />
