是相同等級。普通螺栓與**螺栓的受力性能與計(jì)算方法均有所區(qū)別的。**螺栓的受力首先是通過在其內(nèi)部施加預(yù)拉力P，然后在被連接件之間的接觸面上產(chǎn)生摩擦阻力來承受外荷載的，而普通螺栓則是直接承受外荷載的。 </p> <p> <br /> 四平機(jī)械零件螺栓螺栓性能等級的含義鋼結(jié)構(gòu)連接用螺栓性能等級分幾種？</p><div

螺栓M4對應(yīng)螺母的M4，例如M4-P0.7的螺母只能與M4-P0.7系列的螺栓進(jìn)行連接（在螺母中，M4指螺母內(nèi)徑大約為4mm，0.7指兩個(gè)螺紋牙之間的距離為0.7mm）。 </p> <p> <br /> </p> <p> 螺栓：機(jī)械零件，配用螺母的圓柱形帶螺紋的緊固件。由頭部和螺桿（帶有外螺紋的圓柱體）兩部分組成的一類緊固件，需與螺母配合，用于緊固連接兩個(gè)帶有通孔的零件。 </p> <p> <br /> </p> <p> 這種連接形式稱螺栓連接。如把螺母從螺栓上旋下，又可以使這兩個(gè)零件分開，故螺栓連接是屬于可拆卸連接。 </p> <p> <br /> </p> 螺母是將機(jī)械設(shè)備緊密連接起來的零件，通過內(nèi)側(cè)的螺紋，同等規(guī)格螺母和螺栓才能連接在一起。<p> **度螺栓的連接方式有摩擦連接、承壓連接、混合連接和并用連接和張拉回連接四種 </p> <p> （ 1 ）摩擦型連接：摩擦型**螺栓是一般常說的**螺栓，基于**螺栓緊固時(shí)產(chǎn)生的強(qiáng)大夾緊力來壓緊鋼板束，依靠接觸面間產(chǎn)生的抗剪摩擦力傳遞與螺栓垂直方向應(yīng)力的連接方法。 </p> <p> ( 2 ）承壓型連接：是在螺栓擰緊后所產(chǎn)生的抗滑移力及螺栓桿在螺孔內(nèi)和連接鋼板間產(chǎn)生的承壓力來傳遞應(yīng)力的一種連接方法。 </p> <p> ( 3 ）張拉型連接：接頭在螺栓擰緊后，鋼板間產(chǎn)生的壓力使靂板層處于密貼狀態(tài)，螺栓在軸向拉力作用下，板層間的壓力減少，外力完成由螺栓承擔(dān)。當(dāng)外力作用超過螺拴的預(yù)拉力時(shí)，板層間就互相離開，發(fā)生離間時(shí)的荷載叫做離間荷載，張拉連接其外力應(yīng)小于離間荷載。 </p> <p> ( 4 ）混合連接和并用連接：在**螺栓的接頭中，同時(shí)有幾種方法承受外力，這些連接中有**螺栓的摩擦型連接和承壓型連接并用；有**螺栓連接和焊接混用；有**螺栓和鉚釘并用等，混合連接時(shí)，一個(gè)接頭中兒種外力由各自的連接分別承受；并用連接時(shí)，一個(gè)接頭中幾種連接承受一種外力。 </p> <p> <br /> 螺栓的等級應(yīng)該如何選用？</p><div
