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(di)扭矩大，使(shi)用壽命長，免維護，耐高溫(wen)(wen)，耐酸(suan)堿防腐(fu)蝕(shi)，適用于高溫(wen)(wen)高速及有腐(fu)蝕(shi)工況環(huan)境的軸系傳動。

膜(mo)片型聯軸(zhou)器能補(bu)償(chang)主(zhu)(zhu)動(dong)機與從動(dong)機之間由(you)于制造誤(wu)(wu)差、安裝誤(wu)(wu)差、承載(zai)變形(xing)以及溫升(sheng)變化的影響等所(suo)引起(qi)的軸(zhou)向(xiang)、徑向(xiang)和角向(xiang)偏移(yi)。膜(mo)片彈(dan)性(xing)(xing)聯軸(zhou)器屬金(jin)屬彈(dan)性(xing)(xing)元(yuan)件撓性(xing)(xing)聯軸(zhou)器，其(qi)依靠(kao)金(jin)屬聯軸(zhou)器膜(mo)片來聯接主(zhu)(zhu)、從動(dong)機傳(chuan)遞扭矩，具有彈(dan)性(xing)(xing)減振、無噪(zao)聲、不(bu)需(xu)潤滑(hua)的優(you)點。

膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)軸器(qi)(qi)至(zhi)少由一個(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)和兩(liang)個(ge)軸套組成。膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)被(bei)用銷釘緊(jin)固在軸套上一般不(bu)(bu)會松動或(huo)(huo)引(yin)起膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)和軸套之間的(de)反沖。有(you)一些(xie)生產商提供(gong)兩(liang)個(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)的(de)，也有(you)提供(gong)三個(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)的(de)，中間有(you)一個(ge)或(huo)(huo)兩(liang)個(ge)剛性元件(jian)，兩(liang)邊 再連(lian)在軸套上。單(dan)(dan)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)軸器(qi)(qi)和雙(shuang)(shuang)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)軸器(qi)(qi)的(de)不(bu)(bu)同(tong)之處是(shi)處理各種偏(pian)差(cha)能力的(de)不(bu)(bu)同(tong)，鑒于(yu)其需要(yao)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)能復雜的(de)彎曲，所以單(dan)(dan)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)軸器(qi)(qi)不(bu)(bu)太適應偏(pian)心(xin)。而雙(shuang)(shuang)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)軸器(qi)(qi)可(ke)以同(tong)時曲向(xiang)不(bu)(bu)同(tong)的(de)方向(xiang)，以此(ci)來補償(chang)偏(pian)心(xin)。
