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)緊湊，傳遞扭矩大，使用壽命長(chang)，免維護，耐(nai)高(gao)(gao)溫(wen)，耐(nai)酸(suan)堿防腐蝕(shi)，適用于高(gao)(gao)溫(wen)高(gao)(gao)速及有腐蝕(shi)工況環(huan)境的(de)軸系(xi)傳動。

膜(mo)(mo)片型聯(lian)軸(zhou)器(qi)(qi)(qi)能(neng)補(bu)償(chang)主(zhu)動機(ji)與從(cong)動機(ji)之間由于制造(zao)誤(wu)差(cha)(cha)、安裝誤(wu)差(cha)(cha)、承載(zai)變(bian)形(xing)以(yi)及溫(wen)升變(bian)化的影(ying)響等所引起的軸(zhou)向、徑(jing)向和角(jiao)向偏(pian)移。膜(mo)(mo)片彈性(xing)聯(lian)軸(zhou)器(qi)(qi)(qi)屬金(jin)屬彈性(xing)元件撓性(xing)聯(lian)軸(zhou)器(qi)(qi)(qi)，其依靠金(jin)屬聯(lian)軸(zhou)器(qi)(qi)(qi)膜(mo)(mo)片來聯(lian)接主(zhu)、從(cong)動機(ji)傳遞扭矩，具有彈性(xing)減振、無噪聲(sheng)、不需(xu)潤滑的優點。

膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)至(zhi)少(shao)由一個(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)和兩(liang)個(ge)軸(zhou)套(tao)組成。膜(mo)(mo)片(pian)(pian)(pian)(pian)被用銷釘緊固在軸(zhou)套(tao)上一般(ban)不會松動或引(yin)起膜(mo)(mo)片(pian)(pian)(pian)(pian)和軸(zhou)套(tao)之間(jian)的反沖。有(you)(you)一些生(sheng)產商(shang)提供(gong)兩(liang)個(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)的，也有(you)(you)提供(gong)三個(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)的，中間(jian)有(you)(you)一個(ge)或兩(liang)個(ge)剛(gang)性元件，兩(liang)邊 再連在軸(zhou)套(tao)上。單(dan)膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)和雙膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)的不同(tong)(tong)之處是處理各種偏差(cha)能力的不同(tong)(tong)，鑒(jian)于其(qi)需要膜(mo)(mo)片(pian)(pian)(pian)(pian)能復雜的彎曲，所以單(dan)膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)不太適應偏心(xin)(xin)。而雙膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)可以同(tong)(tong)時曲向(xiang)不同(tong)(tong)的方向(xiang)，以此來(lai)補(bu)償(chang)偏心(xin)(xin)。
