鼓形齒式聯軸器的特色
●齒式聯軸器是由齒數不異的內齒圈和帶外齒的凸緣半聯軸器等整機構成。外齒分為直齒和鼓形齒兩種齒形，所謂鼓形齒即為將外齒制成球面，球面中間在齒輪軸線上，齒側空隙較普通齒輪大，鼓形齒聯軸器可許可較大的角位移（絕對直齒聯軸器），可改良齒的打仗前提，進步通報轉矩的才能，耽誤利用壽命。有角位移時沿齒寬的打仗狀況。
●齒(chi)(chi)(chi)式(shi)(shi)聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)在任(ren)務時，兩(liang)軸(zhou)發生絕(jue)對角位移，表里齒(chi)(chi)(chi)的(de)(de)齒(chi)(chi)(chi)面周期性作軸(zhou)向(xiang)絕(jue)對滑動(dong)，一定構(gou)成(cheng)齒(chi)(chi)(chi)面磨(mo)損和功率(lv)耗損，是以(yi)，齒(chi)(chi)(chi)式(shi)(shi)聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)需在有杰出(chu)和密封的(de)(de)狀況下(xia)任(ren)務。齒(chi)(chi)(chi)式(shi)(shi)聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)徑向(xiang)尺寸小，承(cheng)載才能大，經常使用(yong)(yong)于(yu)(yu)低速(su)重載工況前提的(de)(de)軸(zhou)系(xi)傳動(dong)，高(gao)精度并經動(dong)均(jun)衡(heng)的(de)(de)齒(chi)(chi)(chi)式(shi)(shi)聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)可用(yong)(yong)于(yu)(yu)高(gao)速(su)傳動(dong)，如燃汽輪機的(de)(de)軸(zhou)系(xi)傳動(dong)。因為(wei)鼓形(xing)齒(chi)(chi)(chi)式(shi)(shi)聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)角向(xiang)彌補大于(yu)(yu)直齒(chi)(chi)(chi)式(shi)(shi)聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)，國表里均(jun)普(p??u)遍接(jie)納(na)鼓形(xing)齒(chi)(chi)(chi)式(shi)(shi)聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)，直齒(chi)(chi)(chi)式(shi)(shi)聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)屬(shu)于(yu)(yu)被裁減的(de)(de)產物，選用(yong)(yong)者應盡量不選用(yong)(yong)。
