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(jin)湊，傳(chuan)遞扭矩大，使(shi)用壽命長(chang)，免(mian)維(wei)護，耐高溫，耐酸堿防腐(fu)蝕(shi)，適用于高溫高速及有腐(fu)蝕(shi)工(gong)況環(huan)境的軸系傳(chuan)動(dong)。

膜(mo)片(pian)型聯(lian)軸器能補償主動機與從(cong)動機之間由于制造誤(wu)差、安(an)裝誤(wu)差、承載變(bian)形以及溫(wen)升(sheng)變(bian)化的影響等所引起的軸向(xiang)(xiang)、徑(jing)向(xiang)(xiang)和角向(xiang)(xiang)偏移。膜(mo)片(pian)彈性聯(lian)軸器屬(shu)金屬(shu)彈性元(yuan)件(jian)撓性聯(lian)軸器，其依靠(kao)金屬(shu)聯(lian)軸器膜(mo)片(pian)來(lai)聯(lian)接主、從(cong)動機傳遞扭矩，具有(you)彈性減振(zhen)、無噪聲、不需潤滑的優(you)點(dian)。

膜片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)至少由一(yi)個(ge)膜片(pian)(pian)(pian)和(he)(he)兩(liang)(liang)(liang)個(ge)軸(zhou)(zhou)(zhou)(zhou)套(tao)組成。膜片(pian)(pian)(pian)被用銷釘緊固(gu)在軸(zhou)(zhou)(zhou)(zhou)套(tao)上一(yi)般不(bu)會松動(dong)或引起膜片(pian)(pian)(pian)和(he)(he)軸(zhou)(zhou)(zhou)(zhou)套(tao)之間的(de)(de)(de)反沖。有(you)(you)一(yi)些生產商提(ti)供兩(liang)(liang)(liang)個(ge)膜片(pian)(pian)(pian)的(de)(de)(de)，也有(you)(you)提(ti)供三個(ge)膜片(pian)(pian)(pian)的(de)(de)(de)，中間有(you)(you)一(yi)個(ge)或兩(liang)(liang)(liang)個(ge)剛(gang)性元件，兩(liang)(liang)(liang)邊(bian) 再連在軸(zhou)(zhou)(zhou)(zhou)套(tao)上。單膜片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)和(he)(he)雙(shuang)膜片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)的(de)(de)(de)不(bu)同(tong)(tong)之處(chu)是(shi)處(chu)理(li)各種偏差能力的(de)(de)(de)不(bu)同(tong)(tong)，鑒(jian)于其需要膜片(pian)(pian)(pian)能復雜的(de)(de)(de)彎曲，所以(yi)(yi)單膜片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)不(bu)太適應偏心(xin)。而雙(shuang)膜片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)器(qi)可以(yi)(yi)同(tong)(tong)時曲向(xiang)不(bu)同(tong)(tong)的(de)(de)(de)方向(xiang)，以(yi)(yi)此(ci)來(lai)補(bu)償偏心(xin)。
