zl20齒(chi)(chi)(chi)式(shi)聯(lian)(lian)軸器(qi)是由(you)齒(chi)(chi)(chi)數相(xiang)(xiang)同(tong)的內(nei)齒(chi)(chi)(chi)圈和帶外齒(chi)(chi)(chi)的凸(tu)緣半聯(lian)(lian)軸器(qi)等零件(jian)組成。外齒(chi)(chi)(chi)分為直齒(chi)(chi)(chi)和鼓(gu)(gu)形齒(chi)(chi)(chi)兩種齒(chi)(chi)(chi)形，所謂鼓(gu)(gu)形齒(chi)(chi)(chi)即為將外齒(chi)(chi)(chi)制成球(qiu)面(mian)，球(qiu)面(mian)中心在齒(chi)(chi)(chi)輪軸線上，齒(chi)(chi)(chi)側間隙較一(yi)般齒(chi)(chi)(chi)輪大，鼓(gu)(gu)形齒(chi)(chi)(chi)聯(lian)(lian)軸器(qi)可允許較大的角位移(相(xiang)(xiang)對于直齒(chi)(chi)(chi)聯(lian)(lian)軸器(qi))，可改善齒(chi)(chi)(chi)的接觸條件(jian)，提高傳遞轉矩(ju)的能(neng)力，延(yan)長(chang)使用壽命。

zl20齒(chi)式聯(lian)軸(zhou)器在(zai)工作(zuo)時，兩軸(zhou)產(chan)生(sheng)相對位(wei)移(yi)，內外(wai)齒(chi)的齒(chi)面周期性(xing)作(zuo)軸(zhou)向相對滑動，必然形成(cheng)齒(chi)面磨損和功(gong)率損耗(hao)，因此齒(chi)式聯(lian)軸(zhou)器需在(zai)良好潤(run)滑和密(mi)封的狀態下工作(zuo)。

zl20齒(chi)式(shi)聯軸(zhou)器徑向尺寸小，承載能力大，常用(yong)于(yu)低速重載工(gong)況(kuang)條件(jian)的(de)軸(zhou)系(xi)(xi)傳動(dong)(dong)，如冶金、礦山、起重運輸行業，也適用(yong)于(yu)石(shi)油、化工(gong)、通(tong)用(yong)機(ji)械等行業。高(gao)精度并經動(dong)(dong)平衡(heng)的(de)齒(chi)式(shi)聯軸(zhou)器可用(yong)于(yu)高(gao)速傳動(dong)(dong)，如燃汽輪機(ji)的(de)軸(zhou)系(xi)(xi)傳動(dong)(dong)。由于(yu)鼓形(xing)(xing)齒(chi)式(shi)聯軸(zhou)器的(de)角(jiao)向補(bu)償大于(yu)直齒(chi)式(shi)聯軸(zhou)器，國內外均廣泛(fan)采(cai)用(yong)鼓形(xing)(xing)齒(chi)式(shi)聯軸(zhou)器。
