齒(chi)輪(lun)是指輪(lun)緣(yuan)上有齒(chi)輪(lun)連續嚙合傳(chuan)遞運(yun)動和(he)動力的(de)(de)機械元件(jian)，在機械領域(yu)，有許(xu)多(duo)不(bu)同的(de)(de)參數用來表(biao)達齒(chi)輪(lun)的(de)(de)各種性能，基本的(de)(de)齒(chi)輪(lun)參數有齒(chi)數z（一個齒(chi)輪(lun)的(de)(de)輪(lun)齒(chi)總(zong)數）、模數m（相鄰(lin)兩(liang)輪(lun)齒(chi)同側齒(chi)廓(kuo)間的(de)(de)齒(chi)距p與圓周率π的(de)(de)比(bi)值）、分度圓直(zhi)徑(jing)d（直(zhi)徑(jing)為(wei)模數乘以(yi)齒(chi)數的(de)(de)乘積的(de)(de)圓）、壓力角(jiao)α（兩(liang)齒(chi)廓(kuo)曲(qu)線(xian)(xian)的(de)(de)公法線(xian)(xian)與兩(liang)節圓的(de)(de)公切線(xian)(xian)所(suo)夾的(de)(de)銳角(jiao)）、齒(chi)高和(he)齒(chi)厚等，其中齒(chi)數和(he)模數是齒(chi)輪(lun)最(zui)重(zhong)要的(de)(de)參數。

二、齒輪傳動的特點

齒(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)是(shi)機械(xie)工程學(xue)的(de)一(yi)個專業術語，是(shi)指利用(yong)兩齒(chi)(chi)輪(lun)的(de)輪(lun)齒(chi)(chi)相互(hu)嚙(nie)合傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)(dong)力和(he)運(yun)動(dong)(dong)(dong)(dong)(dong)的(de)機械(xie)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，也是(shi)應用(yong)最廣(guang)泛的(de)一(yi)種機械(xie)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)方式，有(you)圓(yuan)柱(zhu)齒(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、錐齒(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)、行星齒(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)等多種。齒(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)的(de)特點是(shi)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)精度高(gao)、適用(yong)范(fan)圍廣(guang)、傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)效率高(gao)、使(shi)(shi)用(yong)壽(shou)命長，不(bu)過同時齒(chi)(chi)輪(lun)的(de)使(shi)(shi)用(yong)成(cheng)本、制造和(he)安裝的(de)要(yao)求較高(gao)，對于工作的(de)環境條件要(yao)求也比較嚴格，且屬于剛性(xing)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，減振性(xing)和(he)抗(kang)沖擊性(xing)都不(bu)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。

四、齒輪加工工藝過程

齒(chi)(chi)(chi)輪(lun)是許(xu)多機械設(she)備的(de)(de)(de)核(he)心傳動部件(jian)，其加(jia)(jia)工(gong)(gong)(gong)(gong)質(zhi)量(liang)的(de)(de)(de)優劣對機械設(she)備的(de)(de)(de)穩定性(xing)和(he)可靠性(xing)影響巨大(da)，一般齒(chi)(chi)(chi)輪(lun)加(jia)(jia)工(gong)(gong)(gong)(gong)的(de)(de)(de)類型有銑(xian)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(jia)(jia)工(gong)(gong)(gong)(gong)齒(chi)(chi)(chi)輪(lun)的(de)(de)(de)工(gong)(gong)(gong)(gong)藝(yi)過(guo)程(cheng)主(zhu)要包括(kuo)毛坯處理、齒(chi)(chi)(chi)坯加(jia)(jia)工(gong)(gong)(gong)(gong)、齒(chi)(chi)(chi)形(xing)加(jia)(jia)工(gong)(gong)(gong)(gong)、熱(re)處理、齒(chi)(chi)(chi)形(xing)精加(jia)(jia)工(gong)(gong)(gong)(gong)、齒(chi)(chi)(chi)端加(jia)(jia)工(gong)(gong)(gong)(gong)等(deng)階段。
