src="https://tyunfile.71360.com/UploadFile/jinxunjingujian/637388105648767930/5176820.png"></div><p> 彈簧墊圈表面處理方法：<br /> 1.堿性氧化法是將彈簧放進溫度140°C左右，含有氧化劑的氫氧化鈉溶液中浸泡一定時間，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，才能放進常溫劑中進行氧化處理。在對彈簧進行氧化處理后，還應(yīng)對彈簧的處理質(zhì)量進行外觀檢查與抗腐蝕性檢查，以保證發(fā)黑處理有效。 </p><p style="text-indent:25px">彈簧墊圈（DIN127B/GB93）能提供10N/m的彈力，而10N/m的彈力對于280N/m的螺栓預(yù)緊力矩來說可以忽略。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有明顯的嵌痕。所以，彈簧墊圈對螺栓的防松作用可以忽略。從彈簧墊圈的作用及原理來看，用彈簧墊圈來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)防螺絲松動的效果，安裝時要注意方向。**度預(yù)應(yīng)力螺栓都是需要螺母端放置平墊圈的。</p><div

型波形墊圈：WL型為搭口型彈性墊圈，它通常能在較小的空間內(nèi)安裝，比如給軸承施加預(yù)應(yīng)力，減少軸承運轉(zhuǎn)的噪音，提高軸承的運轉(zhuǎn)精度與平穩(wěn)性.另外在電子電器方面也有大量的應(yīng)用。材料有碳鋼、不銹鋼、銅合金等。WN型波形墊圈：WN型為多層波峰重疊型彈性墊圈,該系列與WL型比較,因為由多層材料組成,因此在相同的壓縮行程下的K值曲線較WL型平緩,適用于彈力較大,而整個工作行程彈力釋放又要求較均勻的情況中。所用材料有碳鋼、不銹鋼、銅合金等。圓螺母用止動墊圈又稱止退墊圈，俗名王八墊。四川螺栓墊圈</p><p

我國平墊圈標(biāo)準共有9項，從2000-2002年分別批準發(fā)布了GB/T97.3－2000、GB/T5286－2001、GB/T95－2002、GB/T96.1－2002、GB/T96.2－2002、GB/T97.1－2002、GB/T97.2－2002、GB/T97.4－2002及 GB/T5287－2002 等平墊圈標(biāo)準。<br /> 根據(jù)平墊圈性能等級，筆者推薦使用材料：<br /> 對于100HV級的可選用ST12、ST13及Q235、Q215、Q195等等，表面硬度可達到110HV左右；<br /> 對于140HV級的可選用 08F、08Al及10、10F等等，表面硬度可達到140HV左右；<br /> 對于200HV和300HV級的應(yīng)選用45、50、60、70鋼或65Mn鋼，可通過熱處理淬火回火達到200～300HV和300～400HV技術(shù)要求。<br /> 由于根據(jù)標(biāo)準對于100HV 、140HV級的平墊圈可用低碳鋼制造。一般企業(yè)在選用材料時大多數(shù)是采用寶鋼材料，便于冷沖壓。尼龍墊片規(guī)格</p><p
