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湊，傳(chuan)遞(di)扭矩(ju)大，使用(yong)壽命長(chang)，免維護(hu)，耐(nai)高(gao)溫，耐(nai)酸堿防(fang)腐(fu)蝕(shi)，適用(yong)于高(gao)溫高(gao)速及(ji)有腐(fu)蝕(shi)工況(kuang)環(huan)境的(de)軸(zhou)系傳(chuan)動。

膜片(pian)型聯(lian)(lian)(lian)軸(zhou)器能(neng)補償主(zhu)動機(ji)與從動機(ji)之間由于制造誤差、安裝誤差、承載變(bian)形以(yi)及溫(wen)升變(bian)化的影(ying)響等所引起的軸(zhou)向(xiang)、徑向(xiang)和角向(xiang)偏移。膜片(pian)彈性聯(lian)(lian)(lian)軸(zhou)器屬(shu)金屬(shu)彈性元件撓性聯(lian)(lian)(lian)軸(zhou)器，其依靠金屬(shu)聯(lian)(lian)(lian)軸(zhou)器膜片(pian)來聯(lian)(lian)(lian)接主(zhu)、從動機(ji)傳遞扭矩(ju)，具有(you)彈性減振、無噪聲、不需潤滑的優點。

膜(mo)片(pian)(pian)(pian)聯(lian)(lian)(lian)軸(zhou)器至少由一(yi)個(ge)膜(mo)片(pian)(pian)(pian)和兩(liang)(liang)個(ge)軸(zhou)套(tao)(tao)組成。膜(mo)片(pian)(pian)(pian)被用銷釘緊(jin)固(gu)在軸(zhou)套(tao)(tao)上(shang)一(yi)般不(bu)(bu)(bu)會松動或引起膜(mo)片(pian)(pian)(pian)和軸(zhou)套(tao)(tao)之間的反沖。有一(yi)些生產(chan)商提供兩(liang)(liang)個(ge)膜(mo)片(pian)(pian)(pian)的，也有提供三個(ge)膜(mo)片(pian)(pian)(pian)的，中間有一(yi)個(ge)或兩(liang)(liang)個(ge)剛(gang)性元件，兩(liang)(liang)邊 再連(lian)在軸(zhou)套(tao)(tao)上(shang)。單(dan)膜(mo)片(pian)(pian)(pian)聯(lian)(lian)(lian)軸(zhou)器和雙(shuang)(shuang)膜(mo)片(pian)(pian)(pian)聯(lian)(lian)(lian)軸(zhou)器的不(bu)(bu)(bu)同(tong)(tong)之處(chu)是(shi)處(chu)理各種偏(pian)(pian)差(cha)能力的不(bu)(bu)(bu)同(tong)(tong)，鑒于其需要膜(mo)片(pian)(pian)(pian)能復雜的彎曲，所以單(dan)膜(mo)片(pian)(pian)(pian)聯(lian)(lian)(lian)軸(zhou)器不(bu)(bu)(bu)太適(shi)應偏(pian)(pian)心。而雙(shuang)(shuang)膜(mo)片(pian)(pian)(pian)聯(lian)(lian)(lian)軸(zhou)器可以同(tong)(tong)時曲向不(bu)(bu)(bu)同(tong)(tong)的方向，以此(ci)來補(bu)償偏(pian)(pian)心。
