齒式聯軸器定義.

    齒式聯軸器

    齒(chi)式(shi)聯(lian)軸(zhou)器(qi)是(shi)由(you)齒(chi)數(shu)相(xiang)同(tong)的(de)內(nei)齒(chi)圈(quan)和(he)帶(dai)外(wai)齒(chi)的(de)凸(tu)緣(yuan)半(ban)聯(lian)軸(zhou)器(qi)等(deng)零(ling)件(jian)組(zu)成(cheng)。外(wai)齒(chi)分(fen)為(wei)直(zhi)齒(chi)和(he)鼓(gu)形(xing)齒(chi)兩(liang)種(zhong)齒(chi)形(xing)，所(suo)謂(wei)鼓(gu)形(xing)齒(chi)即(ji)為(wei)將(jiang)外(wai)齒(chi)製(zhi)成(cheng)球(qiu)麵(mian)

，球(qiu)麵(mian)中(zhong)心(xin)在(zai)齒(chi)輪(lun)軸(zhou)線(xian)上(shang)，齒(chi)側(ce)間(jian)隙(xi)較(jiao)一(yi)般(ban)齒(chi)輪(lun)大(da)，鼓(gu)形(xing)齒(chi)聯(lian)軸(zhou)器(qi)可(ke)允(yun)許(xu)較(jiao)大(da)的(de)角(jiao)位(wei)移(yi)(相對於直齒聯軸器)，可ke改gai善shan齒chi的de接jie觸chu條tiao件jian，提ti高gao傳chuan遞di轉zhuan矩ju的de能neng力li
，延yan長chang使shi用yong壽shou命ming。齒chi式shi聯lian軸zhou器qi在zai工gong作zuo時shi
，兩liang軸zhou產chan生sheng相xiang對dui位wei移yi

，內nei外wai齒chi的de齒chi麵mian周zhou期qi性xing作zuo軸zhou向xiang相xiang對dui滑hua動dong，必bi然ran形xing成cheng齒chi麵mian磨mo損sun和he功gong率lv損sun耗hao，因yin此ci齒chi式shi聯lian軸zhou器qi需xu在zai良liang好hao潤run滑hua和he密mi封feng的de狀zhuang態tai下xia工gong作zuo。

    齒式聯軸器徑向尺寸小，承載能力大
，常用於低速重載工況條件的軸係傳動
，如冶金
、礦山、起重運輸行業，也適用於石油、化工
、通tong用yong機ji械xie等deng行xing業ye。高gao精jing度du並bing經jing動dong平ping衡heng的de齒chi式shi聯lian軸zhou器qi可ke用yong於yu高gao速su傳chuan動dong，如ru燃ran汽qi輪lun機ji的de軸zhou係xi傳chuan動dong。由you於yu鼓gu形xing齒chi式shi聯lian軸zhou器qi的de角jiao向xiang補bu償chang大da於yu直zhi齒chi式shi聯lian軸zhou器qi
，國guo內nei外wai均jun廣guang泛fan采cai用yong鼓gu形xing齒chi式shi聯lian軸zhou器qi，直zhi齒chi式shi聯lian軸zhou器qi應ying盡jin量liang不bu選xuan用yong。
