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(jin)湊，傳(chuan)遞扭矩大(da)，使用壽命長(chang)，免維護，耐高溫，耐酸堿(jian)防腐(fu)蝕，適用于高溫高速及有腐(fu)蝕工況環境的軸系(xi)傳(chuan)動。

膜片(pian)型聯(lian)軸(zhou)(zhou)(zhou)器(qi)能補償主動(dong)機與從動(dong)機之間由(you)于制(zhi)造誤差(cha)、安裝誤差(cha)、承載(zai)變形以及溫升變化的影(ying)響等所引起的軸(zhou)(zhou)(zhou)向(xiang)(xiang)(xiang)、徑向(xiang)(xiang)(xiang)和(he)角向(xiang)(xiang)(xiang)偏移。膜片(pian)彈(dan)性(xing)(xing)聯(lian)軸(zhou)(zhou)(zhou)器(qi)屬金(jin)(jin)屬彈(dan)性(xing)(xing)元件撓性(xing)(xing)聯(lian)軸(zhou)(zhou)(zhou)器(qi)，其(qi)依靠金(jin)(jin)屬聯(lian)軸(zhou)(zhou)(zhou)器(qi)膜片(pian)來(lai)聯(lian)接主、從動(dong)機傳遞扭矩(ju)，具有(you)彈(dan)性(xing)(xing)減振(zhen)、無噪聲、不(bu)需潤滑(hua)的優點。

膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)(lian)(lian)軸器至少由(you)一(yi)(yi)個(ge)膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)和兩(liang)(liang)個(ge)軸套(tao)組成(cheng)。膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)被(bei)用(yong)銷(xiao)釘緊固在(zai)軸套(tao)上一(yi)(yi)般不會松動或引起膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)和軸套(tao)之間的(de)(de)反(fan)沖。有(you)一(yi)(yi)些生(sheng)產商提(ti)(ti)供兩(liang)(liang)個(ge)膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)的(de)(de)，也有(you)提(ti)(ti)供三個(ge)膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)的(de)(de)，中間有(you)一(yi)(yi)個(ge)或兩(liang)(liang)個(ge)剛(gang)性元件，兩(liang)(liang)邊 再連在(zai)軸套(tao)上。單(dan)膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)(lian)(lian)軸器和雙(shuang)膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)(lian)(lian)軸器的(de)(de)不同之處是處理各(ge)種偏差能(neng)力的(de)(de)不同，鑒于其需要膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)能(neng)復雜的(de)(de)彎曲，所以(yi)單(dan)膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)(lian)(lian)軸器不太適應(ying)偏心(xin)。而雙(shuang)膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)(lian)(lian)軸器可以(yi)同時曲向不同的(de)(de)方向，以(yi)此來補償(chang)偏心(xin)。
