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(jin)湊，傳遞扭矩大，使用(yong)壽命長(chang)，免(mian)維護，耐高(gao)溫，耐酸堿防腐(fu)蝕，適用(yong)于高(gao)溫高(gao)速及有腐(fu)蝕工(gong)況環(huan)境的軸系傳動。

膜(mo)片型聯(lian)軸(zhou)器能補(bu)償(chang)主(zhu)動(dong)(dong)機與從動(dong)(dong)機之間由于制(zhi)造誤差、安裝誤差、承載變(bian)形以及溫升變(bian)化的影響等(deng)所引起的軸(zhou)向、徑向和角向偏(pian)移。膜(mo)片彈性(xing)(xing)(xing)(xing)聯(lian)軸(zhou)器屬(shu)金(jin)屬(shu)彈性(xing)(xing)(xing)(xing)元(yuan)件撓性(xing)(xing)(xing)(xing)聯(lian)軸(zhou)器，其依(yi)靠(kao)金(jin)屬(shu)聯(lian)軸(zhou)器膜(mo)片來聯(lian)接主(zhu)、從動(dong)(dong)機傳遞(di)扭矩，具有彈性(xing)(xing)(xing)(xing)減(jian)振、無噪聲(sheng)、不需潤(run)滑的優點(dian)。

膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)(qi)至少由一(yi)個膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)和(he)兩(liang)個軸(zhou)(zhou)套組(zu)成。膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)被用銷(xiao)釘緊固在軸(zhou)(zhou)套上一(yi)般不(bu)(bu)(bu)會松動或(huo)引(yin)起(qi)膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)和(he)軸(zhou)(zhou)套之(zhi)間的(de)反沖。有一(yi)些生產商(shang)提(ti)供(gong)兩(liang)個膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)的(de)，也(ye)有提(ti)供(gong)三個膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)的(de)，中(zhong)間有一(yi)個或(huo)兩(liang)個剛性元件(jian)，兩(liang)邊 再連在軸(zhou)(zhou)套上。單膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)(qi)和(he)雙膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)(qi)的(de)不(bu)(bu)(bu)同(tong)(tong)之(zhi)處是處理(li)各種(zhong)偏差能力的(de)不(bu)(bu)(bu)同(tong)(tong)，鑒于(yu)其需要膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)能復雜的(de)彎(wan)曲，所(suo)以(yi)單膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)(qi)不(bu)(bu)(bu)太適(shi)應偏心(xin)。而雙膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)(qi)可以(yi)同(tong)(tong)時(shi)曲向不(bu)(bu)(bu)同(tong)(tong)的(de)方向，以(yi)此(ci)來補償偏心(xin)。
