一、齒輪的基本參數有哪些

齒(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)是(shi)指輪(lun)(lun)(lun)(lun)緣(yuan)上(shang)有齒(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)連續(xu)嚙合傳遞運動和(he)動力的(de)(de)(de)(de)機械元(yuan)件，在機械領域，有許多不同的(de)(de)(de)(de)參(can)數(shu)(shu)(shu)(shu)(shu)用來表達齒(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)的(de)(de)(de)(de)各種性(xing)能，基(ji)本的(de)(de)(de)(de)齒(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)參(can)數(shu)(shu)(shu)(shu)(shu)有齒(chi)(chi)(chi)(chi)數(shu)(shu)(shu)(shu)(shu)z（一個齒(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)的(de)(de)(de)(de)輪(lun)(lun)(lun)(lun)齒(chi)(chi)(chi)(chi)總數(shu)(shu)(shu)(shu)(shu)）、模(mo)數(shu)(shu)(shu)(shu)(shu)m（相鄰兩(liang)輪(lun)(lun)(lun)(lun)齒(chi)(chi)(chi)(chi)同側(ce)齒(chi)(chi)(chi)(chi)廓(kuo)間的(de)(de)(de)(de)齒(chi)(chi)(chi)(chi)距p與(yu)圓(yuan)周率π的(de)(de)(de)(de)比值）、分度圓(yuan)直(zhi)徑d（直(zhi)徑為模(mo)數(shu)(shu)(shu)(shu)(shu)乘(cheng)以齒(chi)(chi)(chi)(chi)數(shu)(shu)(shu)(shu)(shu)的(de)(de)(de)(de)乘(cheng)積的(de)(de)(de)(de)圓(yuan)）、壓(ya)力角(jiao)α（兩(liang)齒(chi)(chi)(chi)(chi)廓(kuo)曲線的(de)(de)(de)(de)公法(fa)線與(yu)兩(liang)節圓(yuan)的(de)(de)(de)(de)公切(qie)線所夾(jia)的(de)(de)(de)(de)銳角(jiao)）、齒(chi)(chi)(chi)(chi)高和(he)齒(chi)(chi)(chi)(chi)厚等，其中(zhong)齒(chi)(chi)(chi)(chi)數(shu)(shu)(shu)(shu)(shu)和(he)模(mo)數(shu)(shu)(shu)(shu)(shu)是(shi)齒(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)最重(zhong)要的(de)(de)(de)(de)參(can)數(shu)(shu)(shu)(shu)(shu)。

二、齒輪傳動的特點

齒(chi)(chi)輪(lun)(lun)傳動(dong)(dong)(dong)(dong)是(shi)(shi)機(ji)械(xie)工程(cheng)學的(de)(de)(de)一個(ge)專業術語，是(shi)(shi)指利用(yong)(yong)(yong)兩(liang)齒(chi)(chi)輪(lun)(lun)的(de)(de)(de)輪(lun)(lun)齒(chi)(chi)相互嚙合傳遞動(dong)(dong)(dong)(dong)力和(he)運動(dong)(dong)(dong)(dong)的(de)(de)(de)機(ji)械(xie)傳動(dong)(dong)(dong)(dong)，也(ye)是(shi)(shi)應(ying)用(yong)(yong)(yong)最廣泛的(de)(de)(de)一種機(ji)械(xie)傳動(dong)(dong)(dong)(dong)方式(shi)，有圓(yuan)柱齒(chi)(chi)輪(lun)(lun)傳動(dong)(dong)(dong)(dong)、錐齒(chi)(chi)輪(lun)(lun)傳動(dong)(dong)(dong)(dong)、行星(xing)齒(chi)(chi)輪(lun)(lun)傳動(dong)(dong)(dong)(dong)等多(duo)種。齒(chi)(chi)輪(lun)(lun)傳動(dong)(dong)(dong)(dong)的(de)(de)(de)特點是(shi)(shi)傳動(dong)(dong)(dong)(dong)精度高(gao)、適用(yong)(yong)(yong)范圍(wei)廣、傳動(dong)(dong)(dong)(dong)效率高(gao)、使(shi)用(yong)(yong)(yong)壽命(ming)長，不過同時齒(chi)(chi)輪(lun)(lun)的(de)(de)(de)使(shi)用(yong)(yong)(yong)成本、制造和(he)安(an)裝(zhuang)的(de)(de)(de)要求較高(gao)，對于工作的(de)(de)(de)環境(jing)條件要求也(ye)比(bi)較嚴格，且(qie)屬于剛性(xing)傳動(dong)(dong)(dong)(dong)，減振性(xing)和(he)抗沖擊性(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。

四、齒輪加工工藝過程

齒(chi)(chi)(chi)(chi)(chi)輪是(shi)許多機(ji)械(xie)設(she)備的核心傳動部件，其加工(gong)(gong)(gong)(gong)質(zhi)量(liang)的優劣(lie)對機(ji)械(xie)設(she)備的穩定性和可靠性影(ying)響巨大，一般齒(chi)(chi)(chi)(chi)(chi)輪加工(gong)(gong)(gong)(gong)的類(lei)型有銑(xian)齒(chi)(chi)(chi)(chi)(chi)、磨齒(chi)(chi)(chi)(chi)(chi)、滾齒(chi)(chi)(chi)(chi)(chi)、插(cha)齒(chi)(chi)(chi)(chi)(chi)、剃(ti)齒(chi)(chi)(chi)(chi)(chi)、珩齒(chi)(chi)(chi)(chi)(chi)六種，加工(gong)(gong)(gong)(gong)齒(chi)(chi)(chi)(chi)(chi)輪的工(gong)(gong)(gong)(gong)藝過程(cheng)主要(yao)包括(kuo)毛坯(pi)處理(li)(li)、齒(chi)(chi)(chi)(chi)(chi)坯(pi)加工(gong)(gong)(gong)(gong)、齒(chi)(chi)(chi)(chi)(chi)形加工(gong)(gong)(gong)(gong)、熱處理(li)(li)、齒(chi)(chi)(chi)(chi)(chi)形精加工(gong)(gong)(gong)(gong)、齒(chi)(chi)(chi)(chi)(chi)端加工(gong)(gong)(gong)(gong)等階(jie)段。
