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。膜片式聯軸器結構緊湊，傳(chuan)遞扭(niu)矩(ju)大，使用(yong)壽(shou)命長(chang)，免維(wei)護，耐高(gao)溫，耐酸(suan)堿(jian)防腐蝕(shi)，適用(yong)于(yu)高(gao)溫高(gao)速及有腐蝕(shi)工況(kuang)環境的(de)軸系傳(chuan)動。

膜(mo)(mo)片(pian)(pian)型聯(lian)(lian)(lian)軸(zhou)器(qi)能補(bu)償主動機(ji)(ji)與從動機(ji)(ji)之(zhi)間由于制造誤差、安(an)裝誤差、承載變形以及溫升變化(hua)的影響等所引起的軸(zhou)向(xiang)、徑向(xiang)和(he)角向(xiang)偏移。膜(mo)(mo)片(pian)(pian)彈性聯(lian)(lian)(lian)軸(zhou)器(qi)屬(shu)金屬(shu)彈性元件(jian)撓性聯(lian)(lian)(lian)軸(zhou)器(qi)，其依靠(kao)金屬(shu)聯(lian)(lian)(lian)軸(zhou)器(qi)膜(mo)(mo)片(pian)(pian)來聯(lian)(lian)(lian)接主、從動機(ji)(ji)傳遞(di)扭矩，具有彈性減振、無噪聲、不需潤(run)滑的優點。

膜(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)器(qi)至(zhi)少由(you)一(yi)個膜(mo)(mo)片(pian)(pian)(pian)和(he)(he)兩個軸(zhou)套(tao)(tao)組成(cheng)。膜(mo)(mo)片(pian)(pian)(pian)被用銷(xiao)釘(ding)緊固在(zai)軸(zhou)套(tao)(tao)上一(yi)般不會松動或引起膜(mo)(mo)片(pian)(pian)(pian)和(he)(he)軸(zhou)套(tao)(tao)之間(jian)的(de)反沖(chong)。有(you)一(yi)些生產商提供兩個膜(mo)(mo)片(pian)(pian)(pian)的(de)，也有(you)提供三(san)個膜(mo)(mo)片(pian)(pian)(pian)的(de)，中間(jian)有(you)一(yi)個或兩個剛性元(yuan)件，兩邊 再(zai)連在(zai)軸(zhou)套(tao)(tao)上。單膜(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)器(qi)和(he)(he)雙膜(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)器(qi)的(de)不同(tong)(tong)之處(chu)(chu)是處(chu)(chu)理各種偏(pian)差(cha)能(neng)力(li)的(de)不同(tong)(tong)，鑒于其需要膜(mo)(mo)片(pian)(pian)(pian)能(neng)復(fu)雜的(de)彎(wan)曲，所以單膜(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)器(qi)不太適(shi)應偏(pian)心。而(er)雙膜(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)器(qi)可以同(tong)(tong)時曲向(xiang)不同(tong)(tong)的(de)方(fang)向(xiang)，以此(ci)來(lai)補(bu)償偏(pian)心。
