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(chuan)遞(di)扭矩大(da)，使用(yong)壽命長，免(mian)維(wei)護(hu)，耐高(gao)溫，耐酸(suan)堿(jian)防腐(fu)蝕，適用(yong)于高(gao)溫高(gao)速及有腐(fu)蝕工況環境的軸系傳(chuan)動。

膜片型(xing)聯(lian)軸器能(neng)補償主動(dong)(dong)機(ji)(ji)與從(cong)動(dong)(dong)機(ji)(ji)之間(jian)由(you)于制造誤(wu)差、安裝誤(wu)差、承載變(bian)形以及溫升(sheng)變(bian)化(hua)的影響等所引起的軸向、徑向和角(jiao)向偏移。膜片彈(dan)性(xing)(xing)聯(lian)軸器屬(shu)(shu)金屬(shu)(shu)彈(dan)性(xing)(xing)元件撓性(xing)(xing)聯(lian)軸器，其依靠(kao)金屬(shu)(shu)聯(lian)軸器膜片來聯(lian)接(jie)主、從(cong)動(dong)(dong)機(ji)(ji)傳遞(di)扭矩，具(ju)有彈(dan)性(xing)(xing)減振、無(wu)噪(zao)聲、不需潤滑的優點。

膜(mo)(mo)(mo)片(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)至少(shao)由一(yi)個(ge)膜(mo)(mo)(mo)片(pian)(pian)和兩(liang)個(ge)軸(zhou)(zhou)套(tao)組成。膜(mo)(mo)(mo)片(pian)(pian)被(bei)用銷釘緊(jin)固在軸(zhou)(zhou)套(tao)上(shang)一(yi)般不(bu)會松動或引起膜(mo)(mo)(mo)片(pian)(pian)和軸(zhou)(zhou)套(tao)之間的反沖(chong)。有(you)(you)一(yi)些(xie)生(sheng)產商提(ti)供兩(liang)個(ge)膜(mo)(mo)(mo)片(pian)(pian)的，也有(you)(you)提(ti)供三個(ge)膜(mo)(mo)(mo)片(pian)(pian)的，中間有(you)(you)一(yi)個(ge)或兩(liang)個(ge)剛性元件，兩(liang)邊 再連在軸(zhou)(zhou)套(tao)上(shang)。單膜(mo)(mo)(mo)片(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)和雙膜(mo)(mo)(mo)片(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)的不(bu)同(tong)(tong)之處是(shi)處理各種偏差能(neng)力(li)的不(bu)同(tong)(tong)，鑒(jian)于其需要膜(mo)(mo)(mo)片(pian)(pian)能(neng)復(fu)雜的彎曲，所以單膜(mo)(mo)(mo)片(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)不(bu)太適應偏心(xin)。而雙膜(mo)(mo)(mo)片(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)可(ke)以同(tong)(tong)時曲向(xiang)(xiang)不(bu)同(tong)(tong)的方向(xiang)(xiang)，以此來補償偏心(xin)。
