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(da)，使用(yong)壽命長，免維護，耐(nai)高(gao)溫，耐(nai)酸堿防腐(fu)蝕(shi)，適用(yong)于高(gao)溫高(gao)速及有(you)腐(fu)蝕(shi)工況環境的軸系傳(chuan)動。

膜片(pian)(pian)型聯(lian)軸(zhou)器(qi)能補償主(zhu)動機(ji)與從(cong)動機(ji)之間(jian)由于制造(zao)誤差、安裝誤差、承載變(bian)形(xing)以及溫升變(bian)化的(de)影響(xiang)等所引起的(de)軸(zhou)向、徑向和(he)角向偏移。膜片(pian)(pian)彈(dan)性聯(lian)軸(zhou)器(qi)屬金屬彈(dan)性元件撓性聯(lian)軸(zhou)器(qi)，其依靠金屬聯(lian)軸(zhou)器(qi)膜片(pian)(pian)來聯(lian)接主(zhu)、從(cong)動機(ji)傳遞扭矩(ju)，具有彈(dan)性減(jian)振、無噪聲(sheng)、不需潤滑的(de)優點。

膜片(pian)(pian)(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)(qi)(qi)至少由(you)一(yi)個(ge)(ge)(ge)膜片(pian)(pian)(pian)(pian)(pian)和兩(liang)(liang)個(ge)(ge)(ge)軸(zhou)(zhou)套(tao)(tao)組成。膜片(pian)(pian)(pian)(pian)(pian)被用銷釘緊(jin)固在軸(zhou)(zhou)套(tao)(tao)上(shang)一(yi)般不(bu)會(hui)松動或引起膜片(pian)(pian)(pian)(pian)(pian)和軸(zhou)(zhou)套(tao)(tao)之(zhi)間(jian)的(de)(de)反沖。有(you)一(yi)些(xie)生產商提供兩(liang)(liang)個(ge)(ge)(ge)膜片(pian)(pian)(pian)(pian)(pian)的(de)(de)，也有(you)提供三個(ge)(ge)(ge)膜片(pian)(pian)(pian)(pian)(pian)的(de)(de)，中(zhong)間(jian)有(you)一(yi)個(ge)(ge)(ge)或兩(liang)(liang)個(ge)(ge)(ge)剛性元(yuan)件(jian)，兩(liang)(liang)邊 再(zai)連在軸(zhou)(zhou)套(tao)(tao)上(shang)。單(dan)膜片(pian)(pian)(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)(qi)(qi)和雙膜片(pian)(pian)(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)(qi)(qi)的(de)(de)不(bu)同之(zhi)處是(shi)處理各種偏(pian)差能(neng)力(li)的(de)(de)不(bu)同，鑒(jian)于其需要膜片(pian)(pian)(pian)(pian)(pian)能(neng)復雜的(de)(de)彎(wan)曲，所(suo)以(yi)(yi)單(dan)膜片(pian)(pian)(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)(qi)(qi)不(bu)太適應偏(pian)心(xin)。而雙膜片(pian)(pian)(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)(qi)(qi)可(ke)以(yi)(yi)同時曲向不(bu)同的(de)(de)方(fang)向，以(yi)(yi)此來補償偏(pian)心(xin)。
