style="text-indent:25px">墊圈的作用就是用來(lái)保護(hù)被連接件的表面不受螺母的擦傷以及分散螺母對(duì)被連接件的壓力的。其實(shí)這不難解釋，只要有零部件有接觸就會(huì)產(chǎn)生摩擦，并且還會(huì)存在一定的縫隙，進(jìn)而使用墊圈可以有效的防止和減輕摩擦，起到良好的密封效果。墊圈的種類和規(guī)格有許多，墊圈分為平墊圈-C級(jí)、大墊圈-A和C級(jí)、小墊圈-A級(jí)，組合墊片、平墊圈-A級(jí)、平墊圈-倒角型-A級(jí)、鋼結(jié)構(gòu)**度墊圈、彈簧墊圈等等二十余種。其中平墊圈一般是用于連接件中一個(gè)是軟質(zhì)地的，組合墊片，一個(gè)是硬質(zhì)地較脆弱的，其主要的作用就是增大接觸面積，分散壓力，組合墊片，防止將質(zhì)地軟的零件壓壞。波形彈簧墊圈國(guó)標(biāo)：GB/T 7246-1987。組合墊片</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="組合墊片,墊圈"

style="text-indent:25px">彈簧墊圈（DIN127B/GB93）的防松：車橋主減速器與橋殼的連接使用10.9級(jí)M16X100螺栓，擰緊力矩為280+20N.m，使用高精度電動(dòng)擰緊機(jī)擰緊。在有彈簧墊圈和沒(méi)有彈簧墊圈兩種狀態(tài)下檢測(cè)螺栓擰緊過(guò)程中力矩隨轉(zhuǎn)角的變化。對(duì)比力矩轉(zhuǎn)角曲線，發(fā)現(xiàn)在有彈簧墊圈的情況下，一直有約10N.m的預(yù)緊力矩;而沒(méi)有彈簧墊圈的情況下，螺栓在力矩明顯上升前，力矩處于0N.m狀態(tài)。以此推斷用約10N.m的螺栓預(yù)緊力矩就可以將彈簧墊圈完全壓平。再通過(guò)用數(shù)顯扭矩扳手檢測(cè)，發(fā)現(xiàn)螺栓扭矩還未達(dá)到20N.m，彈簧墊圈已經(jīng)完全被壓平，驗(yàn)證了上述推斷的正確性。合肥方形墊片螺母支承面的外倒角使軸向夾緊力產(chǎn)生了徑向分力，從而使得彈簧墊圈的開(kāi)口脹大。。</p><div

style="text-indent:25px">平墊圈GB97用料：無(wú)機(jī)械性能要求的平墊圈一般用角料制造，如Q235A，有硬度要求但不高時(shí)可以用較厚板料壓延一下達(dá)到要求的硬度。彈墊等防松用的墊圈一般用65Mn70#或S50CM—S70CM制造，要經(jīng)過(guò)熱處理(淬火+回火)鉚釘、銷軸類：鉚釘、銷軸類一般用料與螺栓相同，但有些鉚釘硬度不可太高，甚至有些要求HRB60以下，一般正?；牧嫌捕仍贖RB70-80，因此有些要經(jīng)過(guò)退火才能達(dá)到性能要求。自攻釘一般用C1018C1020C1022等材料，但國(guó)內(nèi)有些廠家為節(jié)約成本，偷工減料，采用18#15#20#更用些廠家用Q235A，然后表面滲碳處理完事，這樣制成的自攻釘其心部的韌性達(dá)不到要求，易斷。不銹鋼緊固件了解不多，好像SUS304是很常用的。</p><p style="text-indent:25px">每年制造商都會(huì)使用數(shù)十億個(gè)由多種材料制成的墊圈，它們的厚度，直徑，表面處理和等級(jí)多種多樣。供應(yīng)商估計(jì)，制造商將大約三分之二的墊圈用于組裝應(yīng)用，其余的用于維護(hù)生產(chǎn)設(shè)備。大多數(shù)墊圈用于分配由螺紋緊固件施加的夾緊載荷。其他墊圈的設(shè)計(jì)可幫助將緊固件鎖定在適當(dāng)?shù)奈恢没蚴蛊浣^緣，例如防止潮濕和導(dǎo)電。還有一些放置在軸上，用作軸組件中的墊片或起到支撐作用。正確使用墊圈可以使產(chǎn)品組裝真正受益。如果使用不當(dāng)，不必要地使用或?yàn)榱搜谏w設(shè)計(jì)或生產(chǎn)缺陷，墊圈可能根本沒(méi)有任何好處，同時(shí)增加了成本。發(fā)生脹圈的彈簧墊圈必然受到一個(gè)徑向外張力，外張力源于擰緊力矩產(chǎn)生的加緊軸力。</p><div

style="text-indent:25px">彈簧墊圈（DIN127B/GB93）能提供10N/m的彈力，而10N/m的彈力對(duì)于280N/m的螺栓預(yù)緊力矩來(lái)說(shuō)可以忽略。其次，這么小的力，不足以使彈簧墊圈切口處的尖角嵌入螺栓和被連接件表面。折卸后觀察，螺栓和被連接件表面都沒(méi)有明顯的嵌痕。所以，彈簧墊圈對(duì)螺栓的防松作用可以忽略。從彈簧墊圈的作用及原理來(lái)看，用彈簧墊圈來(lái)防松并不是一種很好的防松方法，還是該尋找一種比較理想的靠增加摩擦阻力矩的防松方法。彈簧墊圈除了普通墊圈的作用外，還有預(yù)防螺絲松動(dòng)的效果，安裝時(shí)要注意方向。組合密封墊圈供螺紋管接頭及螺塞密封用。合肥方形墊片</p><p

style="text-indent:25px">彈簧墊圈（DIN127B/GB93）當(dāng)螺栓收縮時(shí),墊圈的斜齒面會(huì)使螺母回到原來(lái)的位置。彈簧墊圈GB93*適用于平坦且較光滑的金屬表面。如果連接材料為非金屬材料,可將一個(gè)金屬板固定在連接材料上,這樣就可以使用制鎖墊圈了。在安裝彈簧墊圈時(shí)無(wú)需使用扭力扳手。在安裝或拆除彈簧墊圈時(shí)也可選擇使用氣動(dòng)工具。墊圈到底起到什么作用呢？在螺栓需要經(jīng)常拆卸的場(chǎng)合，為了保護(hù)被連接件的表面不被劃傷，一般需要在螺母或螺栓頭位置放置平墊圈，這樣就可以防止被連接件表面不被劃傷了。在一些摩擦系數(shù)要求比較準(zhǔn)確的連接處，比如**度預(yù)應(yīng)力螺栓都是需要螺母端放置平墊圈的，因?yàn)檫@種情況下螺栓、螺母、墊圈都是由同一廠家提供的，螺栓生產(chǎn)廠家需要對(duì)螺母和墊圈進(jìn)行相應(yīng)的處理，以保證螺母與墊圈間的摩擦系數(shù)保持一致性。組合墊片</p><p
