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(di)扭矩大，使用(yong)壽(shou)命(ming)長，免維護(hu)，耐高(gao)溫(wen)，耐酸堿防(fang)腐蝕，適(shi)用(yong)于高(gao)溫(wen)高(gao)速及(ji)有腐蝕工況環境的軸系傳(chuan)動。

膜(mo)片(pian)型聯(lian)(lian)軸(zhou)器(qi)能補(bu)償主動(dong)(dong)(dong)機與(yu)從動(dong)(dong)(dong)機之間由于(yu)制造(zao)誤差(cha)、安裝誤差(cha)、承載變形以及溫升變化的(de)影響等所引(yin)起的(de)軸(zhou)向、徑(jing)向和角向偏移。膜(mo)片(pian)彈性(xing)(xing)聯(lian)(lian)軸(zhou)器(qi)屬(shu)金屬(shu)彈性(xing)(xing)元件撓性(xing)(xing)聯(lian)(lian)軸(zhou)器(qi)，其依靠金屬(shu)聯(lian)(lian)軸(zhou)器(qi)膜(mo)片(pian)來聯(lian)(lian)接主、從動(dong)(dong)(dong)機傳(chuan)遞(di)扭矩，具(ju)有彈性(xing)(xing)減振、無噪(zao)聲、不需潤(run)滑的(de)優點。

膜(mo)(mo)片(pian)(pian)聯(lian)軸(zhou)器(qi)至少(shao)由一(yi)(yi)(yi)個(ge)膜(mo)(mo)片(pian)(pian)和(he)兩個(ge)軸(zhou)套(tao)(tao)組成(cheng)。膜(mo)(mo)片(pian)(pian)被(bei)用銷釘緊固在(zai)軸(zhou)套(tao)(tao)上一(yi)(yi)(yi)般不(bu)(bu)會松動或引起膜(mo)(mo)片(pian)(pian)和(he)軸(zhou)套(tao)(tao)之間的反沖。有(you)一(yi)(yi)(yi)些(xie)生產商提供(gong)(gong)兩個(ge)膜(mo)(mo)片(pian)(pian)的，也(ye)有(you)提供(gong)(gong)三個(ge)膜(mo)(mo)片(pian)(pian)的，中(zhong)間有(you)一(yi)(yi)(yi)個(ge)或兩個(ge)剛性元件，兩邊 再(zai)連在(zai)軸(zhou)套(tao)(tao)上。單膜(mo)(mo)片(pian)(pian)聯(lian)軸(zhou)器(qi)和(he)雙膜(mo)(mo)片(pian)(pian)聯(lian)軸(zhou)器(qi)的不(bu)(bu)同(tong)(tong)之處是處理各種偏(pian)(pian)差(cha)能力的不(bu)(bu)同(tong)(tong)，鑒于其需(xu)要膜(mo)(mo)片(pian)(pian)能復雜的彎曲(qu)，所以單膜(mo)(mo)片(pian)(pian)聯(lian)軸(zhou)器(qi)不(bu)(bu)太適應偏(pian)(pian)心(xin)。而雙膜(mo)(mo)片(pian)(pian)聯(lian)軸(zhou)器(qi)可以同(tong)(tong)時曲(qu)向(xiang)(xiang)不(bu)(bu)同(tong)(tong)的方(fang)向(xiang)(xiang)，以此來補(bu)償(chang)偏(pian)(pian)心(xin)。
