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，傳遞扭矩大(da)，使(shi)用壽命長(chang)，免維(wei)護，耐高溫，耐酸堿防腐蝕，適用于高溫高速及有腐蝕工況環境的軸系傳動。

膜(mo)片型聯軸器能補償(chang)主(zhu)動機與從(cong)動機之間由(you)于制造誤(wu)差、安裝誤(wu)差、承載變形以及溫升變化(hua)的(de)影響等所引起的(de)軸向(xiang)(xiang)、徑向(xiang)(xiang)和角向(xiang)(xiang)偏移。膜(mo)片彈(dan)性聯軸器屬金(jin)屬彈(dan)性元件(jian)撓性聯軸器，其依靠金(jin)屬聯軸器膜(mo)片來聯接主(zhu)、從(cong)動機傳遞扭矩，具有彈(dan)性減振、無(wu)噪聲、不需潤滑的(de)優點。

膜(mo)(mo)(mo)片(pian)(pian)聯(lian)(lian)(lian)(lian)軸器至少由一(yi)個(ge)(ge)膜(mo)(mo)(mo)片(pian)(pian)和(he)兩(liang)(liang)(liang)個(ge)(ge)軸套組成。膜(mo)(mo)(mo)片(pian)(pian)被用(yong)銷釘(ding)緊固在軸套上(shang)一(yi)般(ban)不(bu)會松動(dong)或(huo)引起膜(mo)(mo)(mo)片(pian)(pian)和(he)軸套之(zhi)間(jian)的反(fan)沖。有(you)(you)一(yi)些(xie)生產商提供(gong)兩(liang)(liang)(liang)個(ge)(ge)膜(mo)(mo)(mo)片(pian)(pian)的，也有(you)(you)提供(gong)三個(ge)(ge)膜(mo)(mo)(mo)片(pian)(pian)的，中間(jian)有(you)(you)一(yi)個(ge)(ge)或(huo)兩(liang)(liang)(liang)個(ge)(ge)剛性元件(jian)，兩(liang)(liang)(liang)邊 再連在軸套上(shang)。單膜(mo)(mo)(mo)片(pian)(pian)聯(lian)(lian)(lian)(lian)軸器和(he)雙(shuang)膜(mo)(mo)(mo)片(pian)(pian)聯(lian)(lian)(lian)(lian)軸器的不(bu)同(tong)(tong)(tong)之(zhi)處(chu)是處(chu)理各種偏(pian)(pian)(pian)差能力的不(bu)同(tong)(tong)(tong)，鑒于其需要膜(mo)(mo)(mo)片(pian)(pian)能復雜(za)的彎(wan)曲，所以(yi)單膜(mo)(mo)(mo)片(pian)(pian)聯(lian)(lian)(lian)(lian)軸器不(bu)太適應偏(pian)(pian)(pian)心(xin)。而(er)雙(shuang)膜(mo)(mo)(mo)片(pian)(pian)聯(lian)(lian)(lian)(lian)軸器可以(yi)同(tong)(tong)(tong)時曲向不(bu)同(tong)(tong)(tong)的方向，以(yi)此來(lai)補償偏(pian)(pian)(pian)心(xin)。
