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(di)扭(niu)矩大(da)，使用壽命長，免維(wei)護，耐高溫，耐酸堿(jian)防腐(fu)蝕，適用于高溫高速及有腐(fu)蝕工(gong)況環(huan)境的軸系傳(chuan)動。

膜片型(xing)聯(lian)軸(zhou)器能(neng)補償主動機與從(cong)動機之間由于制(zhi)造誤(wu)差、安裝誤(wu)差、承載變(bian)形以(yi)及溫升變(bian)化(hua)的影響等所引(yin)起的軸(zhou)向(xiang)、徑向(xiang)和(he)角向(xiang)偏移。膜片彈性聯(lian)軸(zhou)器屬金屬彈性元件撓性聯(lian)軸(zhou)器，其依(yi)靠金屬聯(lian)軸(zhou)器膜片來聯(lian)接主、從(cong)動機傳遞扭矩，具有彈性減振(zhen)、無噪聲、不需(xu)潤滑的優點(dian)。

膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器至少由一(yi)(yi)個(ge)(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)和(he)兩個(ge)(ge)軸(zhou)套(tao)組成。膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)被用銷釘緊固在(zai)軸(zhou)套(tao)上(shang)(shang)一(yi)(yi)般不(bu)(bu)會(hui)松動或引起(qi)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)和(he)軸(zhou)套(tao)之間(jian)的(de)反沖。有一(yi)(yi)些生產商(shang)提(ti)供(gong)兩個(ge)(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)的(de)，也有提(ti)供(gong)三個(ge)(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)的(de)，中(zhong)間(jian)有一(yi)(yi)個(ge)(ge)或兩個(ge)(ge)剛(gang)性元件，兩邊(bian) 再連(lian)在(zai)軸(zhou)套(tao)上(shang)(shang)。單(dan)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器和(he)雙膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器的(de)不(bu)(bu)同(tong)之處(chu)是處(chu)理各種偏(pian)差能力的(de)不(bu)(bu)同(tong)，鑒于其(qi)需(xu)要膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)能復雜的(de)彎曲，所以(yi)單(dan)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器不(bu)(bu)太適(shi)應偏(pian)心。而雙膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器可以(yi)同(tong)時曲向不(bu)(bu)同(tong)的(de)方向，以(yi)此來補償(chang)偏(pian)心。
