鼓形齒式(shi)聯軸器的特點 
●齒(chi)(chi)(chi)(chi)(chi)式聯(lian)軸器(qi)(qi)是由齒(chi)(chi)(chi)(chi)(chi)數相同的(de)(de)(de)內齒(chi)(chi)(chi)(chi)(chi)圈和帶外(wai)齒(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)凸緣(yuan)半聯(lian)軸器(qi)(qi)等零件(jian)組成(cheng)(cheng)。外(wai)齒(chi)(chi)(chi)(chi)(chi)分為直齒(chi)(chi)(chi)(chi)(chi)和鼓形(xing)齒(chi)(chi)(chi)(chi)(chi)兩種齒(chi)(chi)(chi)(chi)(chi)形(xing)，所謂(wei)鼓形(xing)齒(chi)(chi)(chi)(chi)(chi)即為將(jiang)外(wai)齒(chi)(chi)(chi)(chi)(chi)制成(cheng)(cheng)球面，球面中心在齒(chi)(chi)(chi)(chi)(chi)輪軸線上，齒(chi)(chi)(chi)(chi)(chi)側間隙較(jiao)一般(ban)齒(chi)(chi)(chi)(chi)(chi)輪大(da)，鼓形(xing)齒(chi)(chi)(chi)(chi)(chi)聯(lian)軸器(qi)(qi)可(ke)允(yun)許較(jiao)大(da)的(de)(de)(de)角(jiao)位移（相對于直齒(chi)(chi)(chi)(chi)(chi)聯(lian)軸器(qi)(qi)），可(ke)改善齒(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)接觸(chu)條(tiao)件(jian)，提(ti)高(gao)傳遞轉矩的(de)(de)(de)能力(li)，延長使(shi)用壽命。有角(jiao)位移時沿齒(chi)(chi)(chi)(chi)(chi)寬的(de)(de)(de)接觸(chu)狀態。 
●齒(chi)(chi)式(shi)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)在(zai)工(gong)作時，兩軸(zhou)(zhou)(zhou)產生(sheng)相對(dui)角(jiao)位移，內外齒(chi)(chi)的(de)(de)齒(chi)(chi)面(mian)周期性作軸(zhou)(zhou)(zhou)向相對(dui)滑動，必然(ran)形(xing)(xing)成齒(chi)(chi)面(mian)磨損和功(gong)率消耗，因(yin)此，齒(chi)(chi)式(shi)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)需在(zai)有良好和密封(feng)的(de)(de)狀態下工(gong)作。齒(chi)(chi)式(shi)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)徑向尺寸(cun)小，承載(zai)能力大，常用(yong)于(yu)低速(su)重載(zai)工(gong)況條件的(de)(de)軸(zhou)(zhou)(zhou)系(xi)傳動，高(gao)精度(du)并經動平衡的(de)(de)齒(chi)(chi)式(shi)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)可用(yong)于(yu)高(gao)速(su)傳動，如燃(ran)汽輪機的(de)(de)軸(zhou)(zhou)(zhou)系(xi)傳動。由于(yu)鼓(gu)形(xing)(xing)齒(chi)(chi)式(shi)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)角(jiao)向補償(chang)大于(yu)直(zhi)齒(chi)(chi)式(shi)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)，國內外均廣泛采用(yong)鼓(gu)形(xing)(xing)齒(chi)(chi)式(shi)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)，直(zhi)齒(chi)(chi)式(shi)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)屬于(yu)被淘汰的(de)(de)產品，選用(yong)者應盡量不選用(yong).
