style="text-indent:25px">墊圈的鋁平墊：鋁平墊具有一定的韌性，一般柴油、機(jī)油管路的連接處均可采用。鋁平墊在安裝前應(yīng)檢查其平面是否有凹痕或裂紋，否則將會(huì)產(chǎn)生漏油管內(nèi)吸進(jìn)空氣，不但造成油料的浪費(fèi)，影響發(fā)動(dòng)機(jī)的功率，還會(huì)因機(jī)油供應(yīng)不足致使燒瓦抱軸等故障的發(fā)生。軟木墊具有一定的韌性，一般用于水箱、發(fā)動(dòng)機(jī)油底殼與機(jī)體之間。軟木墊質(zhì)地松軟，密封性能好，緩減部件的震動(dòng)、碰撞和磨損。弱點(diǎn)是松脆易碎。在制作軟木墊時(shí)應(yīng)注意先鉆孔后下料，這樣不易損壞。安裝時(shí)將接合面雜物刮凈，不銹鋼墊片報(bào)價(jià)，不銹鋼墊片報(bào)價(jià)，并在軟木墊的兩面涂上黃油，以增加其密封性能，不銹鋼墊片報(bào)價(jià)。上緊螺栓時(shí)，應(yīng)按對(duì)角順序，均勻用力擰緊固定螺栓。**度預(yù)應(yīng)力螺栓都是需要螺母端放置平墊圈的。不銹鋼墊片報(bào)價(jià)</p><div

一般平墊的作用是為了保護(hù)螺絲桿穿孔，因?yàn)槁輻U穿孔一般比螺桿直徑大2mm左右，且螺栓材質(zhì)強(qiáng)度高，硬度大。為避免在緊螺桿時(shí)傷到螺桿帽與穿孔垂直的結(jié)合面，一般加平墊保護(hù)接合面，且在平墊上加裝彈簧墊。防止因震動(dòng)造成螺栓緩扣，損害設(shè)備使用壽命。一般用于多發(fā)零件，以增加支承面，遮蓋較大的孔眼，以防止損傷零件表面，大墊圈多用于木制零件。平墊是加大接觸面積，并且防止螺栓與工件的摩擦；平墊圈的主要作用是保護(hù)連接件的表面，防止螺栓螺母擰緊時(shí)劃傷工件表面。加大墊圈代理墊圈一般為扁平形的金屬環(huán)，用來(lái)保護(hù)被連接件的表面不受螺母擦傷。</p><div

組合螺栓是指一個(gè)外六角螺栓配上一個(gè)彈墊和一個(gè)平墊組合搓牙緊固在一起的三組合件。組合螺栓也叫外六角組合螺釘，也叫六角組合螺栓。其國(guó)標(biāo)有兩種，一種是十字槽外六角組合螺栓，國(guó)標(biāo)號(hào)為GB9074.13.別一種是不帶十字槽外六角組合螺栓，叫作切邊外六角組合螺栓，國(guó)標(biāo)號(hào)叫GB9074.17。組合螺栓的工藝生產(chǎn)，是先把外六角螺栓墩打出來(lái)，后在手工或自動(dòng)穿墊機(jī)把彈平墊穿上去。后在搓牙。數(shù)量多的話，就用自動(dòng)穿墊機(jī)，數(shù)量太少的話，一般都是工人去穿彈平墊。當(dāng)然組合螺栓里用的彈平墊一般都是專(zhuān)業(yè)用來(lái)做組合螺釘?shù)?。其他常用的彈墊，平墊用來(lái)做組合螺釘是不行的。所以很多都是訂制的彈平墊。彈墊的選擇，材質(zhì)非常重要。要選擇好的彈墊，像Mn65這種材質(zhì)就不錯(cuò)。不好的彈墊組合在組合螺釘上，很容易斷掉，或者壓下去了，彈不起來(lái)。 </p><p style="text-indent:25px">彈簧墊圈（DIN127B/GB93）和平墊圈（DIN125/GB97）的區(qū)別：彈簧墊圈可以起到防松，加大預(yù)緊力的功能，而平墊圈沒(méi)有這項(xiàng)功能，它可以用來(lái)增大緊固接觸面積，防止螺栓與工件的摩擦，保護(hù)連接件的表面防止螺栓螺母擰緊時(shí)劃傷工件表面。但有些重要的連接，如主要依靠壓緊產(chǎn)生摩擦力傳遞動(dòng)力的地方，是不能使用彈簧墊的，用了降低連接剛性，反容易出事，可以不用彈簧墊圈。當(dāng)被連接件的強(qiáng)度較低時(shí)采用平墊或法蘭螺栓以增加接觸面積，在有震動(dòng)、脈沖、介質(zhì)的溫度有比較大的波動(dòng)時(shí)，一定要使用彈簧墊。為防止連接副的松動(dòng)采用防松的彈簧墊圈和多齒形鎖緊墊圈、圓螺母止動(dòng)墊圈以及鞍形、波形、錐形彈性墊圈。</p><div
