style="text-indent:25px">彈簧墊圈（DIN127B/GB93）能提供10N/m的彈力，球形墊片，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，球形墊片，球形墊片，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。橡膠圈一般采用耐油丁腈膠或氟橡膠。球形墊片</p><div

不銹鋼螺栓很少使用碳鋼平墊片的，碳鋼片硬度大，彈性不好對(duì)機(jī)器的接觸表面損害大。對(duì)于平墊，不銹鋼螺栓一般采用不銹鋼平墊片就可以了，但并不一定要這樣，只要能滿足性能要求就可以了。對(duì)于彈墊，不銹鋼彈墊效果都不好，應(yīng)盡量采用彈簧鋼的。<br /> 彈簧墊圈用什么材質(zhì)較好？答：通常用65MN彈簧鋼或70#碳鋼,3Cr13,也可用不銹鋼的材料SUS304或SUS316。 65Mn或者是其他一些低碳鋼，像Q235、Q195等。彈簧墊圈的防松能力很低！尤其在目前歐美各國(guó)要求高可靠性產(chǎn)品中采用率極低，特別是重要的承力結(jié)構(gòu)連接部位早已被拋棄好多年。波紋墊片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。</p><div style="width:100%;text-align:

style="text-indent:25px">防松墊片由兩片相同的墊圈組成一套，每片的上、下面帶有不同鋸齒。一面為凸輪狀大齒，其斜坡角度α大于螺栓螺紋角β，另一面為較密小齒。墊圈安裝時(shí)，要大齒面相對(duì)，成對(duì)安裝。小齒面分別與螺母和被緊固件接觸。擰緊螺栓連接緊固件后，振動(dòng)發(fā)生時(shí)，大齒面會(huì)錯(cuò)動(dòng)抬升，并由α角大于β角的原理來(lái)鎖住螺栓，使之不能松動(dòng)。當(dāng)擰緊螺栓或螺母時(shí)，放射狀鋸齒緊緊咬住接觸面，使墊圈固定住，只允許大齒面間的相對(duì)移動(dòng)。螺栓或螺母的任何松動(dòng)趨勢(shì)都被大鋸齒的這種楔入效果所阻止。兩片墊圈之間的抬升距離大于因螺紋滑動(dòng)引起的螺栓或螺母抬升的距離。</p><p> 彈簧墊圈表面處理方法：<br /> 1.堿性氧化法是將彈簧放進(jìn)溫度140°C左右，含有氧化劑的氫氧化鈉溶液中浸泡一定時(shí)間，氧化劑和氫氧化鈉與鐵作用，天生亞鐵酸鈉和鐵酸鈉，再相互反應(yīng)，天生磁性氧化鐵。<br /> 2.發(fā)黑劑的操縱工藝較為簡(jiǎn)單，其工藝路線為：往油、漂洗、酸行、漂洗、發(fā)黑(在室溫下2~5min)漂洗、水膜置換防銹油。要留意的是：一定要把彈簧工件上的油往盡，清洗干凈后，才能放進(jìn)常溫劑中進(jìn)行氧化處理。在對(duì)彈簧進(jìn)行氧化處理后，還應(yīng)對(duì)彈簧的處理質(zhì)量進(jìn)行外觀檢查與抗腐蝕性檢查，以保證發(fā)黑處理有效。防松墊圈當(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。</p><div
