口碑好齒(chi)(chi)(chi)式聯(lian)(lian)軸器(qi)是(shi)由(you)齒(chi)(chi)(chi)數相(xiang)(xiang)同(tong)的(de)內齒(chi)(chi)(chi)圈和帶外(wai)齒(chi)(chi)(chi)的(de)凸緣半聯(lian)(lian)軸器(qi)等零件組成。外(wai)齒(chi)(chi)(chi)分(fen)為(wei)直(zhi)齒(chi)(chi)(chi)和鼓形(xing)(xing)齒(chi)(chi)(chi)兩種齒(chi)(chi)(chi)形(xing)(xing)，所謂鼓形(xing)(xing)齒(chi)(chi)(chi)即為(wei)將外(wai)齒(chi)(chi)(chi)制成球(qiu)面，球(qiu)面中心在齒(chi)(chi)(chi)輪軸線上，齒(chi)(chi)(chi)側間隙(xi)較(jiao)一般齒(chi)(chi)(chi)輪大，鼓形(xing)(xing)齒(chi)(chi)(chi)聯(lian)(lian)軸器(qi)可允許(xu)較(jiao)大的(de)角位(wei)移(yi)(相(xiang)(xiang)對于直(zhi)齒(chi)(chi)(chi)聯(lian)(lian)軸器(qi))，可改善齒(chi)(chi)(chi)的(de)接觸條件，提(ti)高傳遞(di)轉矩的(de)能力(li)，延長(chang)使(shi)用壽命。

口碑好(hao)齒(chi)式聯軸器(qi)在工(gong)作(zuo)(zuo)時(shi)，兩(liang)軸產生相對位移(yi)，內外(wai)齒(chi)的齒(chi)面周(zhou)期性作(zuo)(zuo)軸向(xiang)相對滑(hua)動，必然形成(cheng)齒(chi)面磨(mo)損(sun)和功率損(sun)耗，因此齒(chi)式聯軸器(qi)需在良好(hao)潤滑(hua)和密封的狀態下(xia)工(gong)作(zuo)(zuo)。

口碑好齒式(shi)(shi)聯(lian)(lian)軸(zhou)器(qi)(qi)徑向尺寸小，承(cheng)載能力大(da)，常用于(yu)(yu)低速(su)重載工況條件的軸(zhou)系傳(chuan)動，如(ru)冶(ye)金、礦(kuang)山(shan)、起(qi)重運(yun)輸行業(ye)，也適用于(yu)(yu)石(shi)油、化工、通用機械等(deng)行業(ye)。高精度(du)并經動平(ping)衡(heng)的齒式(shi)(shi)聯(lian)(lian)軸(zhou)器(qi)(qi)可用于(yu)(yu)高速(su)傳(chuan)動，如(ru)燃汽輪(lun)機的軸(zhou)系傳(chuan)動。由于(yu)(yu)鼓(gu)形齒式(shi)(shi)聯(lian)(lian)軸(zhou)器(qi)(qi)的角向補償大(da)于(yu)(yu)直(zhi)齒式(shi)(shi)聯(lian)(lian)軸(zhou)器(qi)(qi)，國內外(wai)均廣泛采用鼓(gu)形齒式(shi)(shi)聯(lian)(lian)軸(zhou)器(qi)(qi)。
