鼓形齒式聯軸器的特色
●齒(chi)(chi)(chi)(chi)式聯軸器(qi)是由齒(chi)(chi)(chi)(chi)數不異的(de)(de)內齒(chi)(chi)(chi)(chi)圈和(he)帶外(wai)齒(chi)(chi)(chi)(chi)的(de)(de)凸緣半聯軸器(qi)等整機構成(cheng)。外(wai)齒(chi)(chi)(chi)(chi)分為(wei)直(zhi)齒(chi)(chi)(chi)(chi)和(he)鼓形齒(chi)(chi)(chi)(chi)兩種齒(chi)(chi)(chi)(chi)形，所謂鼓形齒(chi)(chi)(chi)(chi)即(ji)為(wei)將外(wai)齒(chi)(chi)(chi)(chi)制成(cheng)球面，球面中間(jian)在齒(chi)(chi)(chi)(chi)輪(lun)軸線上，齒(chi)(chi)(chi)(chi)側空隙較普(pu)通(tong)齒(chi)(chi)(chi)(chi)輪(lun)大，鼓形齒(chi)(chi)(chi)(chi)聯軸器(qi)可(ke)許可(ke)較大的(de)(d?e)角位(wei)移（絕對(dui)直(zhi)齒(chi)(chi)(chi)(chi)聯軸器(qi)），可(ke)改良齒(chi)(chi)(chi)(chi)的(de)(de)打仗前提?，進步通(tong)報轉矩的(de)(de)才能，耽(dan)誤利用(yong)壽命。有角位(wei)移時(shi)沿齒(chi)(chi)(chi)(chi)寬的(de)(de)打仗狀況。

●齒(chi)(chi)式(shi)聯軸(zhou)(zhou)器(qi)(qi)在(zai)任務時，兩軸(zhou)(??zhou)發生絕對(dui)角位(wei)移，表里(li)齒(chi)(chi)的齒(chi)(chi)面(mian)周期性作軸(zhou)(zhou)向(xiang)(xiang)絕對(dui)滑動(dong)，一定構成齒(chi)(chi)面(mian)磨損和功率(lv)耗損，是(shi)以，齒(chi)(chi)式(shi)聯軸(zhou)(zhou)器(qi)(qi)需在(zai)有杰出和密封的狀(zhuang)況下任務。齒(chi)(chi)式(shi)聯軸(zhou)(zhou)器(qi)(qi)徑向(xiang)(xiang)尺寸(cun)小，承載才能大，經常使用(yong)于低速重載工況前提的軸(zhou)(zhou)系傳(chuan)動(dong)，高精度并經動(dong)均衡的齒(chi)(chi)式(shi)聯軸(zhou)(zhou)器(qi)(qi)可用(yong)于高速傳(chuan)動(dong)，如燃汽輪機的軸(zhou)(zhou)系傳(chuan)動(dong)。因(yin)為鼓形(xing)齒(chi)(chi)式(shi)聯軸(zhou)(zhou)器(qi)(qi)角向(xiang)(xiang)彌補大于直齒(chi)(chi)式(shi)聯軸(zhou)(zhou)器(qi)(qi)，國表里(li)均普遍接納鼓形(xing)齒(chi)(chi)式(shi)聯軸(zhou)(zhou)器(qi)(qi)，直齒(chi)(chi)式(shi)聯軸(zhou)(zhou)器(qi)(qi)屬(shu)于被裁減的產物(wu)，選用(yong)者應(ying)盡量不(bu)選用(yong)。
