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(jie)構緊湊，傳(chuan)遞扭矩大，使用壽命長(chang)，免(mian)維護(hu)，耐高溫，耐酸堿防腐(fu)蝕(shi)，適(shi)用于高溫高速及有腐(fu)蝕(shi)工況環境的軸系傳(chuan)動。

膜片型聯(lian)軸器(qi)(qi)能(neng)補償主(zhu)動(dong)(dong)機(ji)與從動(dong)(dong)機(ji)之間由于制造誤(wu)差、安(an)裝(zhuang)誤(wu)差、承(cheng)載變形以(yi)及溫升變化的影響等所引(yin)起的軸向(xiang)、徑向(xiang)和角向(xiang)偏移。膜片彈(dan)性(xing)聯(lian)軸器(qi)(qi)屬金(jin)屬彈(dan)性(xing)元(yuan)件(jian)撓性(xing)聯(lian)軸器(qi)(qi)，其依靠金(jin)屬聯(lian)軸器(qi)(qi)膜片來聯(lian)接主(zhu)、從動(dong)(dong)機(ji)傳遞扭矩(ju)，具有彈(dan)性(xing)減振、無噪(zao)聲、不(bu)需潤滑的優點。

膜片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器(qi)至少由(you)一個膜片(pian)(pian)(pian)(pian)和兩(liang)個軸(zhou)(zhou)套組成(cheng)。膜片(pian)(pian)(pian)(pian)被用(yong)銷釘緊(jin)固在軸(zhou)(zhou)套上一般不(bu)會松動或(huo)引(yin)起膜片(pian)(pian)(pian)(pian)和軸(zhou)(zhou)套之間(jian)的(de)反(fan)沖。有(you)(you)一些生產商提供(gong)兩(liang)個膜片(pian)(pian)(pian)(pian)的(de)，也(ye)有(you)(you)提供(gong)三個膜片(pian)(pian)(pian)(pian)的(de)，中間(jian)有(you)(you)一個或(huo)兩(liang)個剛(gang)性元件(jian)，兩(liang)邊(bian) 再連在軸(zhou)(zhou)套上。單膜片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器(qi)和雙膜片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器(qi)的(de)不(bu)同(tong)(tong)之處是(shi)處理(li)各種偏(pian)差(cha)能力的(de)不(bu)同(tong)(tong)，鑒于其需要膜片(pian)(pian)(pian)(pian)能復雜(za)的(de)彎曲，所以(yi)單膜片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器(qi)不(bu)太適應偏(pian)心。而雙膜片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器(qi)可(ke)以(yi)同(tong)(tong)時(shi)曲向不(bu)同(tong)(tong)的(de)方(fang)向，以(yi)此來(lai)補償偏(pian)心。
