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，傳遞扭矩大(da)，使用(yong)(yong)壽命長，免維護，耐高(gao)溫，耐酸堿防腐(fu)蝕，適用(yong)(yong)于高(gao)溫高(gao)速及(ji)有腐(fu)蝕工況環(huan)境的軸系(xi)傳動。

膜片(pian)型聯(lian)軸(zhou)器(qi)(qi)能補償主(zhu)動(dong)機與從動(dong)機之間由于制造誤差、安(an)裝誤差、承載(zai)變(bian)(bian)形以及溫(wen)升變(bian)(bian)化的(de)影響(xiang)等所引起的(de)軸(zhou)向、徑向和角向偏移。膜片(pian)彈性聯(lian)軸(zhou)器(qi)(qi)屬金屬彈性元件撓(nao)性聯(lian)軸(zhou)器(qi)(qi)，其依靠(kao)金屬聯(lian)軸(zhou)器(qi)(qi)膜片(pian)來聯(lian)接(jie)主(zhu)、從動(dong)機傳遞扭矩，具(ju)有彈性減振、無噪聲、不需潤(run)滑(hua)的(de)優點。

膜(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)器(qi)至少由一(yi)(yi)個膜(mo)(mo)(mo)片(pian)(pian)(pian)和兩(liang)(liang)個軸(zhou)套(tao)組成。膜(mo)(mo)(mo)片(pian)(pian)(pian)被用銷釘緊固在軸(zhou)套(tao)上(shang)一(yi)(yi)般不(bu)(bu)會松動或引起膜(mo)(mo)(mo)片(pian)(pian)(pian)和軸(zhou)套(tao)之間的反沖。有(you)一(yi)(yi)些生產商提供(gong)兩(liang)(liang)個膜(mo)(mo)(mo)片(pian)(pian)(pian)的，也有(you)提供(gong)三個膜(mo)(mo)(mo)片(pian)(pian)(pian)的，中間有(you)一(yi)(yi)個或兩(liang)(liang)個剛(gang)性(xing)元件，兩(liang)(liang)邊 再連在軸(zhou)套(tao)上(shang)。單膜(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)器(qi)和雙膜(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)器(qi)的不(bu)(bu)同(tong)(tong)(tong)之處(chu)是(shi)處(chu)理各種偏(pian)差能(neng)力的不(bu)(bu)同(tong)(tong)(tong)，鑒于其需要膜(mo)(mo)(mo)片(pian)(pian)(pian)能(neng)復雜的彎曲(qu)，所以(yi)單膜(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)器(qi)不(bu)(bu)太適應偏(pian)心。而(er)雙膜(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)器(qi)可以(yi)同(tong)(tong)(tong)時(shi)曲(qu)向不(bu)(bu)同(tong)(tong)(tong)的方(fang)向，以(yi)此來補(bu)償(chang)偏(pian)心。
