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)遞扭矩大，使用壽(shou)命長(chang)，免維護，耐高(gao)溫，耐酸(suan)堿防腐(fu)蝕(shi)(shi)，適用于高(gao)溫高(gao)速(su)及有(you)腐(fu)蝕(shi)(shi)工況環(huan)境的軸系傳(chuan)動。

膜(mo)片(pian)型聯(lian)軸(zhou)(zhou)器(qi)(qi)能補償(chang)主動(dong)(dong)機與從(cong)動(dong)(dong)機之間由于制造誤(wu)(wu)差、安裝(zhuang)誤(wu)(wu)差、承載變(bian)形以及(ji)溫(wen)升變(bian)化的影響等所引起的軸(zhou)(zhou)向、徑向和角向偏移(yi)。膜(mo)片(pian)彈性(xing)聯(lian)軸(zhou)(zhou)器(qi)(qi)屬(shu)金屬(shu)彈性(xing)元件撓性(xing)聯(lian)軸(zhou)(zhou)器(qi)(qi)，其依靠金屬(shu)聯(lian)軸(zhou)(zhou)器(qi)(qi)膜(mo)片(pian)來聯(lian)接主、從(cong)動(dong)(dong)機傳遞扭(niu)矩，具有彈性(xing)減(jian)振、無(wu)噪(zao)聲、不需潤滑(hua)的優點。

膜(mo)(mo)(mo)片(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)至少(shao)由一(yi)個(ge)(ge)膜(mo)(mo)(mo)片(pian)(pian)和兩(liang)(liang)個(ge)(ge)軸(zhou)(zhou)套組成。膜(mo)(mo)(mo)片(pian)(pian)被(bei)用銷釘(ding)緊固在軸(zhou)(zhou)套上一(yi)般不會松(song)動(dong)或引(yin)起(qi)膜(mo)(mo)(mo)片(pian)(pian)和軸(zhou)(zhou)套之間(jian)的(de)(de)反沖。有一(yi)些(xie)生產商(shang)提供(gong)兩(liang)(liang)個(ge)(ge)膜(mo)(mo)(mo)片(pian)(pian)的(de)(de)，也有提供(gong)三個(ge)(ge)膜(mo)(mo)(mo)片(pian)(pian)的(de)(de)，中間(jian)有一(yi)個(ge)(ge)或兩(liang)(liang)個(ge)(ge)剛性元件，兩(liang)(liang)邊 再連(lian)在軸(zhou)(zhou)套上。單膜(mo)(mo)(mo)片(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)和雙膜(mo)(mo)(mo)片(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)的(de)(de)不同(tong)(tong)(tong)之處是處理各種偏差能力的(de)(de)不同(tong)(tong)(tong)，鑒于(yu)其需(xu)要膜(mo)(mo)(mo)片(pian)(pian)能復雜(za)的(de)(de)彎曲(qu)(qu)，所以(yi)單膜(mo)(mo)(mo)片(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)不太(tai)適(shi)應偏心。而雙膜(mo)(mo)(mo)片(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)可以(yi)同(tong)(tong)(tong)時曲(qu)(qu)向不同(tong)(tong)(tong)的(de)(de)方向，以(yi)此來補償偏心。
