鼓形齒式聯軸器

齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)式聯(lian)(lian)軸(zhou)(zhou)器(qi)是由齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)數相(xiang)同的內齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)圈(quan)和帶外(wai)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)的凸緣半聯(lian)(lian)軸(zhou)(zhou)器(qi)等零件(jian)組成。外(wai)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)分為直齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)和鼓(gu)形(xing)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)兩種(zhong)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)形(xing)，所謂(wei)鼓(gu)形(xing)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)即為將外(wai)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)制成球(qiu)面(mian)，球(qiu)面(mian)中(zhong)心在齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪軸(zhou)(zhou)線(xian)上，齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)側間隙較(jiao)一般齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪大(da)，鼓(gu)形(xing)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)聯(lian)(lian)軸(zhou)(zhou)器(qi)可允許較(jiao)大(da)的角(jiao)位(wei)移(yi)(yi)（相(xiang)對于直齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)聯(lian)(lian)軸(zhou)(zhou)器(qi)），可齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)的接(jie)觸(chu)條件(jian)，提高傳(chuan)遞(di)轉(zhuan)矩的能力，延(yan)長使用壽命。有角(jiao)位(wei)移(yi)(yi)時沿齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)寬的接(jie)觸(chu)狀(zhuang)態。

齒(chi)(chi)(chi)式(shi)聯軸(zhou)(zhou)(zhou)(zhou)器(qi)在工(gong)(gong)作時，兩(liang)軸(zhou)(zhou)(zhou)(zhou)產(chan)生(sheng)相對角位移，內外齒(chi)(chi)(chi)的(de)(de)(de)齒(chi)(chi)(chi)面周期性作軸(zhou)(zhou)(zhou)(zhou)向相對滑(hua)動(dong)(dong)，必然形成齒(chi)(chi)(chi)面磨損和(he)功(gong)率消耗，因此(ci)，齒(chi)(chi)(chi)式(shi)聯軸(zhou)(zhou)(zhou)(zhou)器(qi)需在有良好(hao)和(he)密(mi)封的(de)(de)(de)狀態下工(gong)(gong)作。齒(chi)(chi)(chi)式(shi)聯軸(zhou)(zhou)(zhou)(zhou)器(qi)徑向尺寸小(xiao)，承載能力(li)大，常用(yong)于(yu)(yu)(yu)低(di)速重(zhong)載工(gong)(gong)況條件的(de)(de)(de)軸(zhou)(zhou)(zhou)(zhou)系傳(chuan)動(dong)(dong)，并經動(dong)(dong)平衡的(de)(de)(de)齒(chi)(chi)(chi)式(shi)聯軸(zhou)(zhou)(zhou)(zhou)器(qi)可用(yong)于(yu)(yu)(yu)高速傳(chuan)動(dong)(dong)，如(ru)燃(ran)汽輪機的(de)(de)(de)軸(zhou)(zhou)(zhou)(zhou)系傳(chuan)動(dong)(dong)。由于(yu)(yu)(yu)鼓(gu)形齒(chi)(chi)(chi)式(shi)聯軸(zhou)(zhou)(zhou)(zhou)器(qi)角向補償(chang)大于(yu)(yu)(yu)直齒(chi)(chi)(chi)式(shi)聯軸(zhou)(zhou)(zhou)(zhou)器(qi)，   均廣泛采(cai)用(yong)鼓(gu)形齒(chi)(chi)(chi)式(shi)聯軸(zhou)(zhou)(zhou)(zhou)器(qi)，直齒(chi)(chi)(chi)式(shi)聯軸(zhou)(zhou)(zhou)(zhou)器(qi)屬于(yu)(yu)(yu)被淘汰的(de)(de)(de)產(chan)品，選(xuan)用(yong)者應盡量不選(xuan)用(yong)。
