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，使用壽命長，免(mian)維(wei)護，耐高溫，耐酸堿(jian)防腐蝕，適用于高溫高速及有腐蝕工況環(huan)境(jing)的軸系傳動。

膜片(pian)型聯(lian)(lian)軸(zhou)(zhou)器能補償主(zhu)動機與(yu)從動機之間由于制造(zao)誤差、安裝誤差、承載變(bian)(bian)形以及溫升變(bian)(bian)化的影響等所引(yin)起(qi)的軸(zhou)(zhou)向(xiang)、徑向(xiang)和(he)角(jiao)向(xiang)偏移(yi)。膜片(pian)彈性(xing)(xing)聯(lian)(lian)軸(zhou)(zhou)器屬金屬彈性(xing)(xing)元件撓性(xing)(xing)聯(lian)(lian)軸(zhou)(zhou)器，其依靠金屬聯(lian)(lian)軸(zhou)(zhou)器膜片(pian)來聯(lian)(lian)接主(zhu)、從動機傳遞扭矩，具有彈性(xing)(xing)減振、無噪聲、不需潤滑的優點。

膜(mo)片(pian)(pian)(pian)(pian)聯(lian)軸器至少(shao)由一(yi)個膜(mo)片(pian)(pian)(pian)(pian)和(he)兩(liang)(liang)個軸套組成(cheng)。膜(mo)片(pian)(pian)(pian)(pian)被用(yong)銷(xiao)釘緊(jin)固在軸套上(shang)一(yi)般不會松動或引起膜(mo)片(pian)(pian)(pian)(pian)和(he)軸套之(zhi)間的(de)反沖。有一(yi)些生(sheng)產商提(ti)(ti)供兩(liang)(liang)個膜(mo)片(pian)(pian)(pian)(pian)的(de)，也有提(ti)(ti)供三個膜(mo)片(pian)(pian)(pian)(pian)的(de)，中(zhong)間有一(yi)個或兩(liang)(liang)個剛(gang)性(xing)元件，兩(liang)(liang)邊 再連(lian)在軸套上(shang)。單膜(mo)片(pian)(pian)(pian)(pian)聯(lian)軸器和(he)雙膜(mo)片(pian)(pian)(pian)(pian)聯(lian)軸器的(de)不同(tong)(tong)之(zhi)處是處理各種偏差能力的(de)不同(tong)(tong)，鑒于其需要膜(mo)片(pian)(pian)(pian)(pian)能復(fu)雜的(de)彎曲，所以單膜(mo)片(pian)(pian)(pian)(pian)聯(lian)軸器不太適應偏心(xin)。而(er)雙膜(mo)片(pian)(pian)(pian)(pian)聯(lian)軸器可(ke)以同(tong)(tong)時曲向不同(tong)(tong)的(de)方(fang)向，以此(ci)來補償偏心(xin)。
