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(gou)緊湊，傳遞扭矩大，使用壽命長，免維護(hu)，耐高溫，耐酸(suan)堿防腐蝕，適用于高溫高速及有(you)腐蝕工況(kuang)環境的軸(zhou)系傳動。

膜(mo)片(pian)(pian)型聯(lian)軸(zhou)器(qi)能(neng)補(bu)償主動(dong)機與從(cong)動(dong)機之間(jian)由于(yu)制造誤差、安裝(zhuang)誤差、承載變(bian)形(xing)以及溫升變(bian)化(hua)的(de)影響等所(suo)引(yin)起的(de)軸(zhou)向(xiang)、徑向(xiang)和角(jiao)向(xiang)偏(pian)移(yi)。膜(mo)片(pian)(pian)彈性(xing)聯(lian)軸(zhou)器(qi)屬金(jin)屬彈性(xing)元件撓性(xing)聯(lian)軸(zhou)器(qi)，其依靠金(jin)屬聯(lian)軸(zhou)器(qi)膜(mo)片(pian)(pian)來(lai)聯(lian)接主、從(cong)動(dong)機傳遞扭矩，具有彈性(xing)減振、無噪(zao)聲、不需(xu)潤滑的(de)優點。

膜(mo)(mo)片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器至(zhi)少由(you)一個(ge)(ge)(ge)膜(mo)(mo)片(pian)(pian)(pian)和(he)(he)兩(liang)(liang)(liang)個(ge)(ge)(ge)軸(zhou)套(tao)組成。膜(mo)(mo)片(pian)(pian)(pian)被用銷釘緊固在軸(zhou)套(tao)上一般不(bu)(bu)(bu)會松動或(huo)引(yin)起膜(mo)(mo)片(pian)(pian)(pian)和(he)(he)軸(zhou)套(tao)之間(jian)的(de)反沖。有一些生產商(shang)提(ti)(ti)供兩(liang)(liang)(liang)個(ge)(ge)(ge)膜(mo)(mo)片(pian)(pian)(pian)的(de)，也有提(ti)(ti)供三個(ge)(ge)(ge)膜(mo)(mo)片(pian)(pian)(pian)的(de)，中間(jian)有一個(ge)(ge)(ge)或(huo)兩(liang)(liang)(liang)個(ge)(ge)(ge)剛性元件，兩(liang)(liang)(liang)邊 再連在軸(zhou)套(tao)上。單膜(mo)(mo)片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器和(he)(he)雙(shuang)膜(mo)(mo)片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器的(de)不(bu)(bu)(bu)同(tong)(tong)之處(chu)是(shi)處(chu)理各種偏(pian)(pian)差能力的(de)不(bu)(bu)(bu)同(tong)(tong)，鑒(jian)于其需要膜(mo)(mo)片(pian)(pian)(pian)能復雜的(de)彎曲，所以單膜(mo)(mo)片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器不(bu)(bu)(bu)太適應偏(pian)(pian)心。而(er)雙(shuang)膜(mo)(mo)片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器可(ke)以同(tong)(tong)時曲向(xiang)不(bu)(bu)(bu)同(tong)(tong)的(de)方(fang)向(xiang)，以此(ci)來(lai)補償偏(pian)(pian)心。
