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(cou)，傳(chuan)遞扭矩大，使用(yong)壽命長，免維護，耐高溫(wen)，耐酸堿防腐蝕，適用(yong)于高溫(wen)高速及有腐蝕工況環境的軸系(xi)傳(chuan)動(dong)。

膜(mo)片型聯(lian)軸(zhou)(zhou)器(qi)能補償(chang)主動機(ji)與從(cong)動機(ji)之間由于制造誤(wu)差(cha)、安裝誤(wu)差(cha)、承載(zai)變(bian)形以(yi)及溫升變(bian)化的影響等所引起的軸(zhou)(zhou)向、徑(jing)向和(he)角向偏移。膜(mo)片彈(dan)性聯(lian)軸(zhou)(zhou)器(qi)屬金(jin)屬彈(dan)性元件撓性聯(lian)軸(zhou)(zhou)器(qi)，其依靠(kao)金(jin)屬聯(lian)軸(zhou)(zhou)器(qi)膜(mo)片來聯(lian)接主、從(cong)動機(ji)傳(chuan)遞扭矩(ju)，具(ju)有彈(dan)性減振、無噪(zao)聲、不需潤滑的優點。

膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)至少由(you)一個(ge)膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)和兩(liang)個(ge)軸(zhou)(zhou)(zhou)套組成。膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)被用銷釘緊(jin)固在軸(zhou)(zhou)(zhou)套上一般不(bu)會松動或(huo)引起膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)和軸(zhou)(zhou)(zhou)套之間(jian)的(de)反沖(chong)。有(you)(you)一些生產商提供(gong)兩(liang)個(ge)膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)的(de)，也有(you)(you)提供(gong)三個(ge)膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)的(de)，中間(jian)有(you)(you)一個(ge)或(huo)兩(liang)個(ge)剛性元件(jian)，兩(liang)邊 再(zai)連在軸(zhou)(zhou)(zhou)套上。單膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)和雙膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)的(de)不(bu)同(tong)(tong)之處是處理各種偏差(cha)能力的(de)不(bu)同(tong)(tong)，鑒(jian)于其(qi)需要膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)能復雜的(de)彎曲，所以單膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)不(bu)太(tai)適應偏心。而雙膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)可以同(tong)(tong)時曲向不(bu)同(tong)(tong)的(de)方向，以此(ci)來(lai)補償偏心。
