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(cou)，傳遞扭矩大，使用壽命長，免維護，耐高溫，耐酸(suan)堿防腐蝕，適用于高溫高速及有腐蝕工況(kuang)環(huan)境的軸系傳動。

膜(mo)片(pian)型聯(lian)軸器能補償(chang)主動(dong)機(ji)與(yu)從動(dong)機(ji)之(zhi)間(jian)由于制造誤差、安(an)裝(zhuang)誤差、承載(zai)變形(xing)以(yi)及(ji)溫升變化的(de)影響等所引起的(de)軸向、徑向和角向偏(pian)移。膜(mo)片(pian)彈(dan)性聯(lian)軸器屬金(jin)屬彈(dan)性元(yuan)件(jian)撓性聯(lian)軸器，其(qi)依靠金(jin)屬聯(lian)軸器膜(mo)片(pian)來聯(lian)接(jie)主、從動(dong)機(ji)傳遞扭矩，具有(you)彈(dan)性減振、無噪聲、不需潤滑的(de)優點。

膜(mo)(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)軸器(qi)至少由一(yi)個膜(mo)(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)和(he)兩(liang)(liang)個軸套(tao)組成。膜(mo)(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)被(bei)用銷(xiao)釘(ding)緊固(gu)在軸套(tao)上一(yi)般(ban)不會松動或引起膜(mo)(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)和(he)軸套(tao)之間(jian)的反沖。有(you)一(yi)些生(sheng)產商提供(gong)兩(liang)(liang)個膜(mo)(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)的，也有(you)提供(gong)三個膜(mo)(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)的，中間(jian)有(you)一(yi)個或兩(liang)(liang)個剛性元件，兩(liang)(liang)邊(bian) 再(zai)連在軸套(tao)上。單膜(mo)(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)軸器(qi)和(he)雙膜(mo)(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)軸器(qi)的不同(tong)(tong)之處(chu)是處(chu)理各種(zhong)偏(pian)差(cha)能力的不同(tong)(tong)，鑒于其需要膜(mo)(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)能復雜的彎曲，所(suo)以(yi)單膜(mo)(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)軸器(qi)不太適應偏(pian)心(xin)。而雙膜(mo)(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)軸器(qi)可以(yi)同(tong)(tong)時曲向(xiang)不同(tong)(tong)的方向(xiang)，以(yi)此來補(bu)償偏(pian)心(xin)。
