膜片聯軸器在傳遞扭矩的同時通過彈性膜片的的變形來補償軸向和角向的位移，是一種高性能的金屬彈性撓性聯軸器。膜片式聯軸器結構(gou)緊湊，傳遞扭矩大，使用壽命長(chang)，免(mian)維(wei)護，耐(nai)高溫，耐(nai)酸堿(jian)防腐蝕，適用于(yu)高溫高速及(ji)有(you)腐蝕工(gong)況環(huan)境的軸系傳動(dong)。

膜片型聯(lian)(lian)軸(zhou)(zhou)器(qi)能補償主動機(ji)與(yu)從(cong)動機(ji)之(zhi)間(jian)由于(yu)制造誤差、安裝誤差、承載(zai)變(bian)形以及溫升(sheng)變(bian)化的影響等所引(yin)起的軸(zhou)(zhou)向(xiang)、徑向(xiang)和角向(xiang)偏移。膜片彈(dan)性聯(lian)(lian)軸(zhou)(zhou)器(qi)屬(shu)金屬(shu)彈(dan)性元件撓性聯(lian)(lian)軸(zhou)(zhou)器(qi)，其依(yi)靠金屬(shu)聯(lian)(lian)軸(zhou)(zhou)器(qi)膜片來聯(lian)(lian)接主、從(cong)動機(ji)傳遞扭矩，具有彈(dan)性減振、無噪聲(sheng)、不需潤滑(hua)的優點。

膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器(qi)(qi)至少由一(yi)個膜(mo)(mo)片(pian)(pian)(pian)(pian)和兩(liang)(liang)個軸(zhou)(zhou)套組成。膜(mo)(mo)片(pian)(pian)(pian)(pian)被(bei)用銷釘緊固在(zai)軸(zhou)(zhou)套上一(yi)般不會松動(dong)或引(yin)起膜(mo)(mo)片(pian)(pian)(pian)(pian)和軸(zhou)(zhou)套之間的(de)(de)反(fan)沖(chong)。有(you)一(yi)些生(sheng)產商提供兩(liang)(liang)個膜(mo)(mo)片(pian)(pian)(pian)(pian)的(de)(de)，也有(you)提供三(san)個膜(mo)(mo)片(pian)(pian)(pian)(pian)的(de)(de)，中間有(you)一(yi)個或兩(liang)(liang)個剛性元件，兩(liang)(liang)邊 再(zai)連在(zai)軸(zhou)(zhou)套上。單膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器(qi)(qi)和雙膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器(qi)(qi)的(de)(de)不同(tong)(tong)之處是處理各(ge)種(zhong)偏差能(neng)力的(de)(de)不同(tong)(tong)，鑒(jian)于其(qi)需要(yao)膜(mo)(mo)片(pian)(pian)(pian)(pian)能(neng)復雜的(de)(de)彎曲(qu)，所以(yi)(yi)單膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器(qi)(qi)不太適應(ying)偏心(xin)。而雙膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器(qi)(qi)可以(yi)(yi)同(tong)(tong)時曲(qu)向不同(tong)(tong)的(de)(de)方(fang)向，以(yi)(yi)此來補償偏心(xin)。
