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，傳遞扭矩大(da)，使(shi)用(yong)壽命長，免(mian)維護，耐(nai)高溫，耐(nai)酸堿防腐蝕，適用(yong)于高溫高速(su)及有腐蝕工況(kuang)環境的軸系傳動。

膜片型(xing)聯(lian)軸(zhou)(zhou)(zhou)器能(neng)補償主(zhu)動機與從動機之間由于制造誤(wu)差、安(an)裝(zhuang)誤(wu)差、承載(zai)變形以及溫升變化的影響等所引起的軸(zhou)(zhou)(zhou)向、徑向和角(jiao)向偏移。膜片彈(dan)性(xing)聯(lian)軸(zhou)(zhou)(zhou)器屬金屬彈(dan)性(xing)元(yuan)件撓性(xing)聯(lian)軸(zhou)(zhou)(zhou)器，其依靠金屬聯(lian)軸(zhou)(zhou)(zhou)器膜片來聯(lian)接(jie)主(zhu)、從動機傳(chuan)遞扭(niu)矩(ju)，具有(you)彈(dan)性(xing)減振、無噪聲、不需潤(run)滑的優點。

膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)聯軸(zhou)器至(zhi)少由一(yi)個(ge)(ge)(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)和(he)兩(liang)個(ge)(ge)(ge)軸(zhou)套(tao)組成。膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)被用(yong)銷釘緊固在(zai)軸(zhou)套(tao)上一(yi)般不會松動或引起膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)和(he)軸(zhou)套(tao)之間(jian)的(de)(de)(de)反沖。有一(yi)些(xie)生產商提供兩(liang)個(ge)(ge)(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)的(de)(de)(de)，也有提供三個(ge)(ge)(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)的(de)(de)(de)，中間(jian)有一(yi)個(ge)(ge)(ge)或兩(liang)個(ge)(ge)(ge)剛性元(yuan)件，兩(liang)邊 再連在(zai)軸(zhou)套(tao)上。單膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)聯軸(zhou)器和(he)雙(shuang)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)聯軸(zhou)器的(de)(de)(de)不同(tong)(tong)(tong)之處是處理(li)各種偏(pian)差能力的(de)(de)(de)不同(tong)(tong)(tong)，鑒于其需要膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)能復雜的(de)(de)(de)彎曲，所以單膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)聯軸(zhou)器不太適(shi)應(ying)偏(pian)心。而雙(shuang)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)聯軸(zhou)器可(ke)以同(tong)(tong)(tong)時(shi)曲向不同(tong)(tong)(tong)的(de)(de)(de)方(fang)向，以此來補償偏(pian)心。
