齒(chi)(chi)輪(lun)是指輪(lun)緣上(shang)有齒(chi)(chi)輪(lun)連續嚙合(he)傳(chuan)遞運動和(he)動力的(de)(de)(de)(de)機械(xie)元件，在機械(xie)領域(yu)，有許多不(bu)同(tong)的(de)(de)(de)(de)參數(shu)(shu)(shu)用來表達齒(chi)(chi)輪(lun)的(de)(de)(de)(de)各種性(xing)能，基本的(de)(de)(de)(de)齒(chi)(chi)輪(lun)參數(shu)(shu)(shu)有齒(chi)(chi)數(shu)(shu)(shu)z（一(yi)個齒(chi)(chi)輪(lun)的(de)(de)(de)(de)輪(lun)齒(chi)(chi)總數(shu)(shu)(shu)）、模(mo)數(shu)(shu)(shu)m（相(xiang)鄰兩(liang)輪(lun)齒(chi)(chi)同(tong)側齒(chi)(chi)廓間的(de)(de)(de)(de)齒(chi)(chi)距p與圓周(zhou)率(lv)π的(de)(de)(de)(de)比值）、分度(du)圓直徑d（直徑為模(mo)數(shu)(shu)(shu)乘以齒(chi)(chi)數(shu)(shu)(shu)的(de)(de)(de)(de)乘積的(de)(de)(de)(de)圓）、壓(ya)力角α（兩(liang)齒(chi)(chi)廓曲線(xian)的(de)(de)(de)(de)公法線(xian)與兩(liang)節圓的(de)(de)(de)(de)公切線(xian)所夾的(de)(de)(de)(de)銳(rui)角）、齒(chi)(chi)高和(he)齒(chi)(chi)厚等，其中齒(chi)(chi)數(shu)(shu)(shu)和(he)模(mo)數(shu)(shu)(shu)是齒(chi)(chi)輪(lun)最重要(yao)的(de)(de)(de)(de)參數(shu)(shu)(shu)。

二、齒輪傳動的特點

齒(chi)(chi)(chi)(chi)(chi)輪傳(chuan)動(dong)(dong)(dong)是機械工程學的一個專業術語(yu)，是指利用(yong)兩齒(chi)(chi)(chi)(chi)(chi)輪的輪齒(chi)(chi)(chi)(chi)(chi)相(xiang)互嚙合傳(chuan)遞(di)動(dong)(dong)(dong)力和運動(dong)(dong)(dong)的機械傳(chuan)動(dong)(dong)(dong)，也是應用(yong)最廣泛(fan)的一種(zhong)機械傳(chuan)動(dong)(dong)(dong)方式，有圓柱齒(chi)(chi)(chi)(chi)(chi)輪傳(chuan)動(dong)(dong)(dong)、錐(zhui)齒(chi)(chi)(chi)(chi)(chi)輪傳(chuan)動(dong)(dong)(dong)、行星齒(chi)(chi)(chi)(chi)(chi)輪傳(chuan)動(dong)(dong)(dong)等多種(zhong)。齒(chi)(chi)(chi)(chi)(chi)輪傳(chuan)動(dong)(dong)(dong)的特點是傳(chuan)動(dong)(dong)(dong)精度高(gao)(gao)、適用(yong)范圍廣、傳(chuan)動(dong)(dong)(dong)效率高(gao)(gao)、使(shi)用(yong)壽命長，不(bu)過同(tong)時(shi)齒(chi)(chi)(chi)(chi)(chi)輪的使(shi)用(yong)成本(ben)、制(zhi)造(zao)和安裝的要(yao)求(qiu)較(jiao)高(gao)(gao)，對于工作的環境條件要(yao)求(qiu)也比較(jiao)嚴格，且(qie)屬于剛性(xing)傳(chuan)動(dong)(dong)(dong)，減(jian)振性(xing)和抗沖擊性(xing)都不(bu)太理(li)想(xiang)。

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。

四、齒輪加工工藝過程

齒(chi)(chi)(chi)輪(lun)是許多機(ji)械設(she)(she)備的核心傳(chuan)動部件，其(qi)加工質量的優劣對機(ji)械設(she)(she)備的穩定(ding)性和可靠性影響巨(ju)大，一般(ban)齒(chi)(chi)(chi)輪(lun)加工的類(lei)型有銑齒(chi)(chi)(chi)、磨齒(chi)(chi)(chi)、滾齒(chi)(chi)(chi)、插齒(chi)(chi)(chi)、剃齒(chi)(chi)(chi)、珩齒(chi)(chi)(chi)六種，加工齒(chi)(chi)(chi)輪(lun)的工藝過程主要包括毛坯(pi)處理、齒(chi)(chi)(chi)坯(pi)加工、齒(chi)(chi)(chi)形加工、熱處理、齒(chi)(chi)(chi)形精加工、齒(chi)(chi)(chi)端加工等階(jie)段(duan)。
