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(gou)緊(jin)湊，傳遞扭矩(ju)大，使用壽命(ming)長，免維護，耐(nai)(nai)高(gao)溫，耐(nai)(nai)酸堿防腐蝕，適用于高(gao)溫高(gao)速及有腐蝕工況環境的軸系傳動。

膜片型聯(lian)(lian)軸(zhou)器能補償主動(dong)機與從(cong)(cong)動(dong)機之(zhi)間由(you)于制造誤差、安裝(zhuang)誤差、承載變(bian)形以及溫升變(bian)化的(de)影(ying)響等(deng)所引起(qi)的(de)軸(zhou)向、徑向和角向偏移。膜片彈性聯(lian)(lian)軸(zhou)器屬金屬彈性元件撓性聯(lian)(lian)軸(zhou)器，其依靠金屬聯(lian)(lian)軸(zhou)器膜片來聯(lian)(lian)接主、從(cong)(cong)動(dong)機傳遞扭(niu)矩，具有(you)彈性減振(zhen)、無噪聲(sheng)、不需潤滑的(de)優點(dian)。

膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)器(qi)至少由一(yi)個(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)和(he)兩(liang)個(ge)軸(zhou)套(tao)組成。膜(mo)(mo)片(pian)(pian)(pian)(pian)被(bei)用銷釘(ding)緊固在(zai)(zai)軸(zhou)套(tao)上(shang)一(yi)般不會(hui)松動或引起膜(mo)(mo)片(pian)(pian)(pian)(pian)和(he)軸(zhou)套(tao)之(zhi)間的(de)(de)反沖。有(you)一(yi)些生產商提(ti)供兩(liang)個(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)的(de)(de)，也有(you)提(ti)供三個(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)的(de)(de)，中(zhong)間有(you)一(yi)個(ge)或兩(liang)個(ge)剛性(xing)元件，兩(liang)邊 再連在(zai)(zai)軸(zhou)套(tao)上(shang)。單(dan)膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)器(qi)和(he)雙膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)器(qi)的(de)(de)不同(tong)(tong)(tong)之(zhi)處(chu)是處(chu)理各種偏差能力的(de)(de)不同(tong)(tong)(tong)，鑒于其(qi)需要膜(mo)(mo)片(pian)(pian)(pian)(pian)能復雜的(de)(de)彎曲，所以(yi)單(dan)膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)器(qi)不太適應偏心。而雙膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)器(qi)可以(yi)同(tong)(tong)(tong)時曲向(xiang)不同(tong)(tong)(tong)的(de)(de)方向(xiang)，以(yi)此來補償偏心。
