style="text-indent:25px">平墊圈DIN125主要用于減小壓強，當(dāng)有的部位擰緊軸向力很大時，易使墊圈壓成碟形，這時可改用材料和提高硬度來解決。彈簧墊圈DIN127B的鎖緊效果一般，重要部位盡量少用或不用，而采用自鎖結(jié)構(gòu)。對于用于高速擰緊（氣動或電動）的彈簧墊圈，較好采用表面磷化處理的墊圈，提高其減磨性能，否則易摩擦發(fā)熱而燒壞或張口，甚至損壞被連接件表面。對于薄板連接處，不應(yīng)采用彈簧墊圈結(jié)構(gòu)。據(jù)統(tǒng)計，彈簧墊圈在汽車上使用得越來越少了。齒形彈性墊圈中的連接齒形由于鎖緊力大而且均勻，在汽車行業(yè)中使用較多，而間隔齒型的則少一些。對于彈簧墊圈、彈性墊圈，根據(jù)國標(biāo)，一般可選擇GB699-1999《優(yōu)良碳素結(jié)構(gòu)鋼》中的60、70鋼和65Mn鋼。</p><p> 一般平墊的作用是為了保護螺絲桿穿孔，因為螺桿穿孔一般比螺桿直徑大2mm左右，且螺栓材質(zhì)強度高，硬度大。為避免在緊螺桿時傷到螺桿帽與穿孔垂直的結(jié)合面，一般加平墊保護接合面，且在平墊上加裝彈簧墊。防止因震動造成螺栓緩扣，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連接件的表面，防止螺栓螺母擰緊時劃傷工件表面。 **度預(yù)應(yīng)力螺栓都是需要螺母端放置平墊圈的。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="杭州防松墊片,墊圈"

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，而平墊圈沒有這項功能，它可以用來增大緊固接觸面積，防止螺栓與工件的摩擦，保護連接件的表面防止螺栓螺母擰緊時劃傷工件表面。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)被連接件的強度較低時采用平墊或法蘭螺栓以增加接觸面積，在有震動、脈沖、介質(zhì)的溫度有比較大的波動時，一定要使用彈簧墊。WL 型波形墊圈為搭口型彈性墊圈,它通常能在較小的空間內(nèi)安裝。杭州防松墊片</p><p style="text-indent:25px">內(nèi)齒彈性墊圈用于頭部尺寸較小的螺釘頭下;外齒彈性墊圈多用于螺栓頭和螺母下。杭州防松墊片</p><p style="text-indent:25px">彈簧墊圈（DIN127B/GB93）開口脹圈及氫脆斷裂原因：1.彈簧墊圈發(fā)生脹圈現(xiàn)象，一般不是彈簧墊圈本身的問題。2.發(fā)生脹圈的彈簧墊圈必然受到一個徑向外張力，外張力源于擰緊力矩產(chǎn)生的加緊軸力。3.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口脹大。倒角直徑越小，發(fā)生脹圈的可能性就越大4.在螺母和彈簧墊圈之間加一個平墊圈有助于減緩或者阻止脹圈現(xiàn)象的發(fā)生，但是平墊圈太薄或者太軟也不能防止發(fā)生脹圈5.彈簧墊圈氫脆斷裂原因一般都是有熱處理工藝不合理還有就是電鍍鋅后沒有及時做去氫處理才導(dǎo)致的斷裂。杭州防松墊片</p><p
