二、齒輪傳動的特點
齒(chi)(chi)輪(lun)傳動(dong)是機械(xie)工(gong)程學的(de)(de)(de)(de)一個專業(ye)術語,是指利用(yong)兩齒(chi)(chi)輪(lun)的(de)(de)(de)(de)輪(lun)齒(chi)(chi)相互嚙合傳遞動(dong)力(li)和運(yun)動(dong)的(de)(de)(de)(de)機械(xie)傳動(dong),也是應用(yong)最廣(guang)泛(fan)的(de)(de)(de)(de)一種機械(xie)傳動(dong)方式,有(you)圓柱齒(chi)(chi)輪(lun)傳動(dong)、錐(zhui)齒(chi)(chi)輪(lun)傳動(dong)、行星齒(chi)(chi)輪(lun)傳動(dong)等多種。齒(chi)(chi)輪(lun)傳動(dong)的(de)(de)(de)(de)特點是傳動(dong)精度高(gao)、適用(yong)范圍廣(guang)、傳動(dong)效率高(gao)、使用(yong)壽命長,不過同時(shi)齒(chi)(chi)輪(lun)的(de)(de)(de)(de)使用(yong)成(cheng)本、制(zhi)造(zao)和安裝的(de)(de)(de)(de)要求較高(gao),對(dui)于工(gong)作的(de)(de)(de)(de)環境條件要求也比較嚴格,且屬于剛性(xing)傳動(dong),減振性(xing)和抗沖(chong)擊性(xing)都不太理想。
三、齒輪模數怎么計算
模數是人們設定的一個能度量齒輪大小的參數,它是一個比值,其大小與分圓齒厚有關,齒輪模數的計算公式是:齒輪模數m=分度圓直徑d/齒數z =齒距p /圓周率π。直徑一定的情況下,模數越大說明齒越大、齒距越大,說明外形尺寸越大,強度越高,單精密度也越低,因此在實際的齒輪設計時,要根據齒輪的厚度、變位等參數以及齒輪的使用環境等,選擇正規齒輪品牌采購齒輪。

齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)是許多機械設(she)備的(de)核(he)心傳動部件(jian),其加(jia)(jia)工(gong)(gong)(gong)(gong)質(zhi)量的(de)優劣對(dui)機械設(she)備的(de)穩定性(xing)(xing)和可靠性(xing)(xing)影響巨(ju)大(da),一般齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)加(jia)(jia)工(gong)(gong)(gong)(gong)的(de)類(lei)型有銑齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)、磨齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)、滾齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)、插齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)、剃齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)、珩(heng)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)六(liu)種,加(jia)(jia)工(gong)(gong)(gong)(gong)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)的(de)工(gong)(gong)(gong)(gong)藝過程主要(yao)包括毛坯處理、齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)坯加(jia)(jia)工(gong)(gong)(gong)(gong)、齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)形加(jia)(jia)工(gong)(gong)(gong)(gong)、熱處理、齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)形精(jing)加(jia)(jia)工(gong)(gong)(gong)(gong)、齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)端加(jia)(jia)工(gong)(gong)(gong)(gong)等階段。
