GL滾子鏈聯(lian)軸器利用(yong)共用(yong)鏈條將兩個帶(dai)鏈齒的半聯(lian)嚙(nie)合(he)聯(lian)接，從而(er)傳遞扭矩(ju)的聯(lian)軸器，結構簡單，裝(zhuang)拆方便(bian)，安裝(zhuang)精度要求低，有(you)一(yi)定的補(bu)償能力。

滾(gun)子鏈(lian)(lian)聯(lian)(lian)軸(zhou)器(qi)是(shi)(shi)利(li)用(yong)公用(yong)的鏈(lian)(lian)條(tiao)，同(tong)時與兩(liang)個齒數相同(tong)的并列(lie)鏈(lian)(lian)輪(lun)嚙合。不同(tong)結構型式的滾(gun)子鏈(lian)(lian)聯(lian)(lian)軸(zhou)器(qi)主要(yao)區別(bie)是(shi)(shi)采用(yong)不同(tong)的鏈(lian)(lian)條(tiao)，常見的有雙(shuang)排(pai)滾(gun)子鏈(lian)(lian)聯(lian)(lian)軸(zhou)器(qi)、單(dan)排(pai)滾(gun)子鏈(lian)(lian)聯(lian)(lian)軸(zhou)器(qi)、齒形鏈(lian)(lian)聯(lian)(lian)軸(zhou)器(qi)、尼龍(long)鏈(lian)(lian)聯(lian)(lian)軸(zhou)器(qi)等。

滾子鏈(lian)條聯(lian)軸(zhou)器具有結構簡單(dan)(四個件(jian)組成)、裝(zhuang)拆方便、拆卸(xie)時不用(yong)移動(dong)被聯(lian)接的(de)(de)兩軸(zhou)、尺寸緊湊、質量輕、有一定補償能(neng)力、對安(an)裝(zhuang)精度要求不高(gao)、工作可(ke)靠、壽命較長、成本較低等優點，滾子鏈(lian)聯(lian)軸(zhou)器應(ying)在良(liang)好的(de)(de)潤滑并有防護罩(zhao)的(de)(de)條件(jian)下工作。

鏈條聯軸(zhou)器可用(yong)于紡織、農機(ji)、起重運輸、工(gong)(gong)(gong)程(cheng)、礦山、輕工(gong)(gong)(gong)、化工(gong)(gong)(gong)等(deng)機(ji)械的軸(zhou)系傳(chuan)動。適(shi)用(yong)于高溫、潮濕和多塵工(gong)(gong)(gong)況環境，不(bu)適(shi)用(yong)于高速、有劇烈沖(chong)擊載(zai)荷和傳(chuan)遞(di)軸(zhou)向力的場合，鏈條聯軸(zhou)器應(ying)在良好的潤滑并有防護罩的條件下工(gong)(gong)(gong)作。
