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(di)扭矩大，使(shi)用壽命長，免維(wei)護，耐高溫，耐酸堿防腐蝕，適用于(yu)高溫高速及有腐蝕工(gong)況環(huan)境的軸系(xi)傳動。

膜(mo)片(pian)(pian)型聯(lian)軸器(qi)(qi)能補(bu)償主動機與(yu)從動機之間由于制(zhi)造誤差、安裝誤差、承載變(bian)(bian)形以及溫(wen)升變(bian)(bian)化的影響等所引起的軸向、徑向和角向偏移。膜(mo)片(pian)(pian)彈(dan)性(xing)聯(lian)軸器(qi)(qi)屬金屬彈(dan)性(xing)元件(jian)撓性(xing)聯(lian)軸器(qi)(qi)，其(qi)依靠金屬聯(lian)軸器(qi)(qi)膜(mo)片(pian)(pian)來聯(lian)接(jie)主、從動機傳遞扭矩，具有彈(dan)性(xing)減振、無噪聲(sheng)、不需潤滑的優點。

膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯軸(zhou)器(qi)(qi)至少由(you)一(yi)個(ge)(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)和(he)兩(liang)(liang)個(ge)(ge)軸(zhou)套(tao)(tao)組成(cheng)。膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)被(bei)用(yong)銷(xiao)釘(ding)緊固在(zai)(zai)軸(zhou)套(tao)(tao)上一(yi)般不會松動或引起(qi)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)和(he)軸(zhou)套(tao)(tao)之間(jian)(jian)的(de)(de)(de)反沖。有一(yi)些生產商提(ti)(ti)供兩(liang)(liang)個(ge)(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)的(de)(de)(de)，也有提(ti)(ti)供三個(ge)(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)的(de)(de)(de)，中(zhong)間(jian)(jian)有一(yi)個(ge)(ge)或兩(liang)(liang)個(ge)(ge)剛性元件，兩(liang)(liang)邊 再連在(zai)(zai)軸(zhou)套(tao)(tao)上。單膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯軸(zhou)器(qi)(qi)和(he)雙(shuang)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯軸(zhou)器(qi)(qi)的(de)(de)(de)不同之處是處理各(ge)種偏(pian)差(cha)能力的(de)(de)(de)不同，鑒(jian)于其(qi)需要膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)能復雜(za)的(de)(de)(de)彎曲(qu)，所以(yi)單膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯軸(zhou)器(qi)(qi)不太適應偏(pian)心。而(er)雙(shuang)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯軸(zhou)器(qi)(qi)可以(yi)同時曲(qu)向不同的(de)(de)(de)方向，以(yi)此(ci)來補(bu)償偏(pian)心。
