蛇形彈簧聯軸器是(shi)一(yi)種(zhong)(zhong)結構(gou)先進的(de)(de)金屬聯(lian)軸(zhou)(zhou)器(qi)，它(ta)靠蛇(she)形(xing)(xing)彈簧片來傳(chuan)遞(di)扭矩(ju)，蛇(she)形(xing)(xing)彈簧聯(lian)軸(zhou)(zhou)器(qi)是(shi)軸(zhou)(zhou)聯(lian)接(jie)傳(chuan)動(dong)部(bu)件，也是(shi)一(yi)種(zhong)(zhong)非(fei)常通(tong)用(yong)(yong)(yong)的(de)(de)軸(zhou)(zhou)聯(lian)接(jie)傳(chuan)動(dong)部(bu)件。蛇(she)簧聯(lian)軸(zhou)(zhou)器(qi)承(cheng)受(shou)扭矩(ju)較(jiao)大，適(shi)用(yong)(yong)(yong)于重型(xing)機械及通(tong)用(yong)(yong)(yong)機械場合。這(zhe)種(zhong)(zhong)經過特殊工藝(yi)處的(de)(de)蛇(she)形(xing)(xing)彈簧，具有很長的(de)(de)使用(yong)(yong)(yong)壽(shou)命　允許轉速較(jiao)高，在軸(zhou)(zhou)向、徑向和(he)角向具有良好(hao)的(de)(de)補償能力。結構(gou)簡單；拆裝方便，使用(yong)(yong)(yong)壽(shou)命長；減(jian)振效果(guo)好(hao)，避免了(le)共振。

蛇(she)形聯(lian)軸器共有九類(lei)型(xing)(xing)(xing)(xing)式，分別是JS罩殼(ke)徑向(xiang)安(an)(an)(an)裝型(xing)(xing)(xing)(xing)（基本型(xing)(xing)(xing)(xing)）、JSB罩殼(ke)軸向(xiang)安(an)(an)(an)裝型(xing)(xing)(xing)(xing)、JSS雙法(fa)蘭(lan)(lan)聯(lian)接型(xing)(xing)(xing)(xing)、JSD單(dan)法(fa)蘭(lan)(lan)聯(lian)接型(xing)(xing)(xing)(xing)、SJS接中間(jian)軸型(xing)(xing)(xing)(xing)、JSG高速型(xing)(xing)(xing)(xing)、JSZ帶(dai)制(zhi)動(dong)(dong)輪(lun)型(xing)(xing)(xing)(xing)、JSP帶(dai)制(zhi)動(dong)(dong)盤(pan)型(xing)(xing)(xing)(xing)、JSA安(an)(an)(an)全型(xing)(xing)(xing)(xing)等(deng)。

蛇簧聯軸器其主要結構是由兩個半聯軸節，兩個半外罩，兩個密封圈及蛇形彈簧片組成。它是靠蛇簧嵌入兩半聯軸節的齒槽內來傳遞扭矩，聯軸器以蛇形彈簧片嵌入兩個半聯軸節的齒槽內，來實現主動軸與從動軸的鏈接。蛇型彈簧聯軸器運轉(zhuan)時，是靠主動端(duan)齒(chi)面對蛇簧(huang)(huang)的(de)(de)軸向(xiang)作用力(li)帶動從動端(duan)，來傳(chuan)遞扭(niu)矩(ju)(ju)，如此在(zai)(zai)很大程度(du)上避免(mian)了共振現象發生(sheng)，且(qie)簧(huang)(huang)片在(zai)(zai)傳(chuan)遞扭(niu)矩(ju)(ju)時所產(chan)生(sheng)的(de)(de)彈性變量，使機械系(xi)統能獲得較好的(de)(de)減振效果(guo)，其平均減振率(lv)達36%以上。
