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(jie)構緊湊，傳遞扭矩大，使用(yong)壽命長，免維護，耐高(gao)溫，耐酸堿防(fang)腐(fu)蝕，適用(yong)于高(gao)溫高(gao)速及有腐(fu)蝕工(gong)況環(huan)境的軸系傳動。

膜(mo)片(pian)型聯(lian)(lian)(lian)軸(zhou)器能補償(chang)主(zhu)(zhu)動機與(yu)從動機之間由(you)于制造(zao)誤差、安裝(zhuang)誤差、承載變形以及溫(wen)升變化的(de)影響等(deng)所引起的(de)軸(zhou)向、徑向和角向偏(pian)移。膜(mo)片(pian)彈(dan)性(xing)(xing)聯(lian)(lian)(lian)軸(zhou)器屬金(jin)屬彈(dan)性(xing)(xing)元(yuan)件撓性(xing)(xing)聯(lian)(lian)(lian)軸(zhou)器，其依靠金(jin)屬聯(lian)(lian)(lian)軸(zhou)器膜(mo)片(pian)來聯(lian)(lian)(lian)接主(zhu)(zhu)、從動機傳遞扭(niu)矩，具有(you)彈(dan)性(xing)(xing)減振、無噪聲、不需(xu)潤滑(hua)的(de)優點。

膜(mo)(mo)(mo)片(pian)(pian)聯(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)至少由一(yi)(yi)個(ge)(ge)(ge)膜(mo)(mo)(mo)片(pian)(pian)和兩(liang)(liang)個(ge)(ge)(ge)軸(zhou)(zhou)(zhou)(zhou)套(tao)(tao)組成。膜(mo)(mo)(mo)片(pian)(pian)被(bei)用銷釘緊固在軸(zhou)(zhou)(zhou)(zhou)套(tao)(tao)上一(yi)(yi)般不(bu)(bu)(bu)會(hui)松動或引起膜(mo)(mo)(mo)片(pian)(pian)和軸(zhou)(zhou)(zhou)(zhou)套(tao)(tao)之間(jian)(jian)的(de)反沖。有(you)一(yi)(yi)些生產(chan)商提供兩(liang)(liang)個(ge)(ge)(ge)膜(mo)(mo)(mo)片(pian)(pian)的(de)，也有(you)提供三個(ge)(ge)(ge)膜(mo)(mo)(mo)片(pian)(pian)的(de)，中間(jian)(jian)有(you)一(yi)(yi)個(ge)(ge)(ge)或兩(liang)(liang)個(ge)(ge)(ge)剛性(xing)元件，兩(liang)(liang)邊(bian) 再連在軸(zhou)(zhou)(zhou)(zhou)套(tao)(tao)上。單膜(mo)(mo)(mo)片(pian)(pian)聯(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)和雙膜(mo)(mo)(mo)片(pian)(pian)聯(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)的(de)不(bu)(bu)(bu)同(tong)(tong)之處(chu)是處(chu)理各種偏(pian)差能力的(de)不(bu)(bu)(bu)同(tong)(tong)，鑒于其需要膜(mo)(mo)(mo)片(pian)(pian)能復雜(za)的(de)彎(wan)曲，所以單膜(mo)(mo)(mo)片(pian)(pian)聯(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)不(bu)(bu)(bu)太適應偏(pian)心。而(er)雙膜(mo)(mo)(mo)片(pian)(pian)聯(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)可以同(tong)(tong)時曲向(xiang)不(bu)(bu)(bu)同(tong)(tong)的(de)方向(xiang)，以此來補(bu)償偏(pian)心。
