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(chuan)遞(di)扭矩(ju)大，使(shi)用(yong)壽命(ming)長，免維護，耐(nai)高溫(wen)，耐(nai)酸(suan)堿防(fang)腐(fu)蝕，適用(yong)于(yu)高溫(wen)高速及(ji)有(you)腐(fu)蝕工況環境的軸(zhou)系傳(chuan)動。

膜(mo)片型(xing)聯軸器能補償主(zhu)動機與從動機之(zhi)間由于(yu)制(zhi)造誤差(cha)、安裝誤差(cha)、承載變(bian)形以及溫升(sheng)變(bian)化(hua)的影響等(deng)所引起(qi)的軸向、徑向和角(jiao)向偏移。膜(mo)片彈(dan)性(xing)聯軸器屬(shu)金屬(shu)彈(dan)性(xing)元件撓性(xing)聯軸器，其依(yi)靠(kao)金屬(shu)聯軸器膜(mo)片來(lai)聯接主(zhu)、從動機傳遞扭矩，具有彈(dan)性(xing)減振(zhen)、無噪聲、不需潤滑的優點(dian)。

膜(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)器(qi)至少由一(yi)個(ge)(ge)膜(mo)片(pian)(pian)(pian)(pian)(pian)(pian)和(he)兩(liang)個(ge)(ge)軸(zhou)套(tao)組成(cheng)。膜(mo)片(pian)(pian)(pian)(pian)(pian)(pian)被用銷釘緊固在軸(zhou)套(tao)上(shang)一(yi)般不會松動或(huo)引起膜(mo)片(pian)(pian)(pian)(pian)(pian)(pian)和(he)軸(zhou)套(tao)之間(jian)的(de)(de)反(fan)沖。有一(yi)些(xie)生產商(shang)提(ti)供兩(liang)個(ge)(ge)膜(mo)片(pian)(pian)(pian)(pian)(pian)(pian)的(de)(de)，也有提(ti)供三個(ge)(ge)膜(mo)片(pian)(pian)(pian)(pian)(pian)(pian)的(de)(de)，中間(jian)有一(yi)個(ge)(ge)或(huo)兩(liang)個(ge)(ge)剛性(xing)元件(jian)，兩(liang)邊 再連在軸(zhou)套(tao)上(shang)。單(dan)膜(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)器(qi)和(he)雙(shuang)膜(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)器(qi)的(de)(de)不同之處是(shi)處理各種(zhong)偏(pian)差能(neng)(neng)力的(de)(de)不同，鑒于其需要(yao)膜(mo)片(pian)(pian)(pian)(pian)(pian)(pian)能(neng)(neng)復雜的(de)(de)彎曲(qu)，所(suo)以單(dan)膜(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)器(qi)不太適(shi)應(ying)偏(pian)心(xin)(xin)。而(er)雙(shuang)膜(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)器(qi)可以同時曲(qu)向不同的(de)(de)方向，以此來補償偏(pian)心(xin)(xin)。
