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)遞扭矩大，使用(yong)壽命長(chang)，免(mian)維(wei)護，耐高溫，耐酸堿防腐(fu)蝕，適用(yong)于(yu)高溫高速及有腐(fu)蝕工況環境的軸系傳(chuan)動。

膜(mo)片(pian)型聯(lian)軸(zhou)器(qi)能補償(chang)主(zhu)動(dong)機與從動(dong)機之間(jian)由于制造誤差(cha)、安裝誤差(cha)、承載變形以及溫(wen)升變化的(de)影響等所引起的(de)軸(zhou)向、徑向和角向偏(pian)移。膜(mo)片(pian)彈(dan)(dan)(dan)性(xing)(xing)聯(lian)軸(zhou)器(qi)屬(shu)金(jin)(jin)屬(shu)彈(dan)(dan)(dan)性(xing)(xing)元件撓(nao)性(xing)(xing)聯(lian)軸(zhou)器(qi)，其依靠金(jin)(jin)屬(shu)聯(lian)軸(zhou)器(qi)膜(mo)片(pian)來(lai)聯(lian)接主(zhu)、從動(dong)機傳遞扭矩，具有彈(dan)(dan)(dan)性(xing)(xing)減振、無噪聲、不需潤滑的(de)優點。

膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)(qi)至少由(you)一(yi)個(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)和(he)兩(liang)個(ge)軸(zhou)套(tao)(tao)組(zu)成。膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)被用銷釘緊固在軸(zhou)套(tao)(tao)上一(yi)般不會(hui)松動或(huo)引起(qi)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)和(he)軸(zhou)套(tao)(tao)之(zhi)間的(de)反沖。有一(yi)些生產(chan)商提供兩(liang)個(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)的(de)，也有提供三個(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)的(de)，中間有一(yi)個(ge)或(huo)兩(liang)個(ge)剛性元件，兩(liang)邊(bian) 再連在軸(zhou)套(tao)(tao)上。單(dan)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)(qi)和(he)雙膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)(qi)的(de)不同(tong)(tong)之(zhi)處(chu)是處(chu)理各種(zhong)偏差能(neng)力的(de)不同(tong)(tong)，鑒于其需要膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)能(neng)復雜的(de)彎曲(qu)，所以(yi)單(dan)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)(qi)不太適(shi)應偏心。而雙膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)(qi)可以(yi)同(tong)(tong)時曲(qu)向(xiang)不同(tong)(tong)的(de)方向(xiang)，以(yi)此來補償偏心。
