GL滾(gun)子(zi)鏈聯(lian)軸器利用(yong)共用(yong)鏈條將(jiang)兩(liang)個(ge)帶鏈齒(chi)的(de)半聯(lian)嚙合聯(lian)接，從而傳遞扭矩(ju)的(de)聯(lian)軸器，結構簡單，裝拆(chai)方便，安(an)裝精度要(yao)求低(di)，有一(yi)定的(de)補償能力。

滾(gun)子(zi)鏈(lian)(lian)(lian)(lian)聯(lian)軸(zhou)器(qi)(qi)(qi)(qi)是利(li)用公用的(de)鏈(lian)(lian)(lian)(lian)條(tiao)，同(tong)(tong)時(shi)與兩個齒(chi)數(shu)相同(tong)(tong)的(de)并列鏈(lian)(lian)(lian)(lian)輪嚙合。不同(tong)(tong)結構(gou)型式(shi)的(de)滾(gun)子(zi)鏈(lian)(lian)(lian)(lian)聯(lian)軸(zhou)器(qi)(qi)(qi)(qi)主(zhu)要(yao)區別是采用不同(tong)(tong)的(de)鏈(lian)(lian)(lian)(lian)條(tiao)，常見的(de)有雙排(pai)(pai)滾(gun)子(zi)鏈(lian)(lian)(lian)(lian)聯(lian)軸(zhou)器(qi)(qi)(qi)(qi)、單(dan)排(pai)(pai)滾(gun)子(zi)鏈(lian)(lian)(lian)(lian)聯(lian)軸(zhou)器(qi)(qi)(qi)(qi)、齒(chi)形(xing)鏈(lian)(lian)(lian)(lian)聯(lian)軸(zhou)器(qi)(qi)(qi)(qi)、尼龍鏈(lian)(lian)(lian)(lian)聯(lian)軸(zhou)器(qi)(qi)(qi)(qi)等。

滾子鏈條聯(lian)(lian)軸(zhou)器具有結構簡單(四個件組成(cheng))、裝拆(chai)方便、拆(chai)卸時不(bu)(bu)用移動被聯(lian)(lian)接的兩軸(zhou)、尺寸緊湊、質量輕、有一定(ding)補償能力、對(dui)安裝精度要求(qiu)不(bu)(bu)高、工(gong)作可靠、壽命(ming)較(jiao)長、成(cheng)本(ben)較(jiao)低(di)等(deng)優點(dian)，滾子鏈聯(lian)(lian)軸(zhou)器應在良好的潤(run)滑并(bing)有防護(hu)罩(zhao)的條件下工(gong)作。

鏈條聯軸器(qi)可用于紡織、農(nong)機、起重運輸、工程、礦(kuang)山、輕(qing)工、化工等機械的(de)(de)軸系(xi)傳動。適(shi)用于高(gao)(gao)溫(wen)、潮濕和多塵工況環(huan)境，不(bu)適(shi)用于高(gao)(gao)速(su)、有劇(ju)烈沖擊載荷和傳遞軸向力的(de)(de)場合，鏈條聯軸器(qi)應在良好的(de)(de)潤滑并有防(fang)護罩(zhao)的(de)(de)條件下工作。
