style="text-indent:25px">平墊圈通常是各種形狀的薄件，用于減少摩擦、防止泄漏、隔離、防止松脫或分散壓力。許多材料和結(jié)構(gòu)中都有這種部件，用于履行各類相似的功效。受螺紋緊固件的材料與工藝限制，螺栓等緊固件的支承面不大，因此為減小承壓面的壓應力保護被連接件的表面，其采用墊圈?！榉乐惯B接副的松動采用防松的彈墊圈和多齒形鎖緊墊圈、圓螺母止動墊圈以及鞍形、波形、錐形彈性墊圈。平墊圈主要用于減小壓強，當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。福建雙疊墊圈防松墊圈外側(cè)是帶有放射狀凸紋面，而內(nèi)側(cè)為斜齒面。</p><div

style="text-indent:25px">墊圈讓原本的防松方法提升了不僅一個梯度。我們就來了解一下常見的防松方法吧。常用的防松方法有三種:摩擦防松、機械防松和長效防松。機械防松和摩擦防松稱為可拆卸防松,而長效防松稱為不可拆卸防松。常用的長效防松有:點焊、鉚接、粘合等。這種方法在拆卸時大多要破壞螺紋緊固件,無法重復使用。常見摩擦防松有:利用墊圈、自鎖螺母及雙螺母等。常見的機械防松方法:利用開口銷、止動墊圈及串鋼絲繩等。機械防松的方法比較可靠,對于重要的聯(lián)接要使用機械防松的方法。</p><p style="text-indent:25px">墊圈在重型汽車上的應用：重型汽車的四輪驅(qū)動變速箱采用防松墊園螺紋絲錐制作箱體上的螺紋孔。以前緊固的方法包括有三個部分,即適用8級的雙頭螺栓,一個鎖緊墊圈片和一個螺母。用了防松墊圈后,不僅簡化了裝配工序,而且還消除了箱體表面上的雙端螺栓松脫問題。防松墊圈技術(shù)現(xiàn)已用到各類重型載貨車上。防松墊圈的防松特性逐漸被汽車行業(yè)所了解。車輪螺母是容易松動脫落,成為安全隱患。采用了防松墊園后,到目前為止,還沒有發(fā)現(xiàn)螺母松動的情況。目前,汽車的傳動軸與后橋連接螺母、汽車發(fā)動機支承架螺母也開始采用防松墊園。平墊圈一般用在連接件中一個是軟質(zhì)地的，一個是硬質(zhì)地較脆的。</p><div

style="text-indent:25px">在螺紋緊固件中因螺栓、螺釘、螺母的支承面不可能做得很大(受材料與工藝的限制),為減小承壓面的壓應力,保護被連接件的表面而采用墊圈。平墊圈材料選擇:墊圈應采用熱軋鋼板,熱軋并酸洗的鋼板或冷軋鋼板沖壓加工或者采用棒料、管料切削以及輾壓、鍛造等加工方法制造。具體加工方法由制造者選擇確定。平墊圈加工工藝:平墊圈加工工藝主要有兩種,一種是今去除毛刺處理,另一種是表面保護處理;去除毛刺處理,墊圈應采用拋光、震動或其他方法去除毛刺及飛邊。防松墊圈當裝配時，內(nèi)側(cè)斜齒面間相對，外側(cè)放射狀凸紋面與兩端接觸面成咬合狀態(tài)。福建雙疊墊圈</p><p style="text-indent:25px">內(nèi)鋸齒墊圈和外鋸齒墊圈兩者的主要作用都是利用鋸齒咬合螺紋或者被緊固面防松鎖緊。福建雙疊墊圈</p><p style="text-indent:25px">各種機器及部件在連接裝配中離不開緊固件。緊固件給機械工業(yè)帶來了方便，但是，它有一個不可避免的弱點，即在劇烈震動中會自行松脫，致使部件或一**整的設(shè)備損壞、解體甚至釀成事故。防松墊圈可以起到防止螺紋松動的作用。防松墊圈的品種很多，有蝶形墊圈，鞍形墊圈，彈墊圈,波形彈墊圈等等，通稱防松墊圈。以上這些類型的防松墊圈都是靠增加靜態(tài)摩擦力來起到防松效果的，低震動，輕載，勻速的狀態(tài)下防松效果可以滿足企業(yè)需求。但在強震動，高載荷，快速運動狀態(tài)下達不到完全防松效果，只是延長了螺母與螺栓自行松脫的時間。福建雙疊墊圈</p><p
