一、齒輪的基本參數有哪些

齒(chi)(chi)(chi)(chi)輪(lun)是(shi)(shi)指輪(lun)緣上有齒(chi)(chi)(chi)(chi)輪(lun)連續嚙合傳遞運(yun)動(dong)和動(dong)力的(de)(de)(de)機(ji)(ji)械(xie)(xie)元件，在機(ji)(ji)械(xie)(xie)領域，有許多不同的(de)(de)(de)參(can)數(shu)用來表達齒(chi)(chi)(chi)(chi)輪(lun)的(de)(de)(de)各(ge)種性能，基本的(de)(de)(de)齒(chi)(chi)(chi)(chi)輪(lun)參(can)數(shu)有齒(chi)(chi)(chi)(chi)數(shu)z（一個齒(chi)(chi)(chi)(chi)輪(lun)的(de)(de)(de)輪(lun)齒(chi)(chi)(chi)(chi)總數(shu)）、模(mo)數(shu)m（相鄰兩(liang)輪(lun)齒(chi)(chi)(chi)(chi)同側齒(chi)(chi)(chi)(chi)廓(kuo)間(jian)的(de)(de)(de)齒(chi)(chi)(chi)(chi)距p與(yu)圓(yuan)周率(lv)π的(de)(de)(de)比值）、分度圓(yuan)直徑(jing)d（直徑(jing)為模(mo)數(shu)乘以(yi)齒(chi)(chi)(chi)(chi)數(shu)的(de)(de)(de)乘積的(de)(de)(de)圓(yuan)）、壓力角(jiao)α（兩(liang)齒(chi)(chi)(chi)(chi)廓(kuo)曲線(xian)(xian)的(de)(de)(de)公(gong)法線(xian)(xian)與(yu)兩(liang)節圓(yuan)的(de)(de)(de)公(gong)切(qie)線(xian)(xian)所夾的(de)(de)(de)銳角(jiao)）、齒(chi)(chi)(chi)(chi)高(gao)和齒(chi)(chi)(chi)(chi)厚(hou)等，其中齒(chi)(chi)(chi)(chi)數(shu)和模(mo)數(shu)是(shi)(shi)齒(chi)(chi)(chi)(chi)輪(lun)最重要的(de)(de)(de)參(can)數(shu)。

二、齒輪傳動的特點

齒(chi)輪傳(chuan)(chuan)動(dong)(dong)(dong)是機(ji)械(xie)工(gong)程學的(de)(de)一個(ge)專業(ye)術(shu)語，是指利用(yong)兩齒(chi)輪的(de)(de)輪齒(chi)相互嚙(nie)合傳(chuan)(chuan)遞動(dong)(dong)(dong)力和運動(dong)(dong)(dong)的(de)(de)機(ji)械(xie)傳(chuan)(chuan)動(dong)(dong)(dong)，也是應用(yong)最廣泛(fan)的(de)(de)一種機(ji)械(xie)傳(chuan)(chuan)動(dong)(dong)(dong)方式，有圓柱齒(chi)輪傳(chuan)(chuan)動(dong)(dong)(dong)、錐(zhui)齒(chi)輪傳(chuan)(chuan)動(dong)(dong)(dong)、行星齒(chi)輪傳(chuan)(chuan)動(dong)(dong)(dong)等多(duo)種。齒(chi)輪傳(chuan)(chuan)動(dong)(dong)(dong)的(de)(de)特點是傳(chuan)(chuan)動(dong)(dong)(dong)精度高(gao)、適用(yong)范圍廣、傳(chuan)(chuan)動(dong)(dong)(dong)效率高(gao)、使用(yong)壽(shou)命(ming)長，不過同時齒(chi)輪的(de)(de)使用(yong)成本、制造和安裝的(de)(de)要求較高(gao)，對于工(gong)作的(de)(de)環境條件(jian)要求也比較嚴格(ge)，且屬于剛性(xing)傳(chuan)(chuan)動(dong)(dong)(dong)，減振性(xing)和抗沖擊性(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)輪(lun)(lun)是(shi)許多機械(xie)設備的核(he)心傳動部件，其加工(gong)(gong)(gong)(gong)質量的優(you)劣對(dui)機械(xie)設備的穩定性(xing)和可靠性(xing)影響巨大，一般齒(chi)(chi)(chi)輪(lun)(lun)加工(gong)(gong)(gong)(gong)的類型有銑齒(chi)(chi)(chi)、磨(mo)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(zhong)，加工(gong)(gong)(gong)(gong)齒(chi)(chi)(chi)輪(lun)(lun)的工(gong)(gong)(gong)(gong)藝過程主要包(bao)括毛坯處理(li)、齒(chi)(chi)(chi)坯加工(gong)(gong)(gong)(gong)、齒(chi)(chi)(chi)形(xing)加工(gong)(gong)(gong)(gong)、熱處理(li)、齒(chi)(chi)(chi)形(xing)精加工(gong)(gong)(gong)(gong)、齒(chi)(chi)(chi)端加工(gong)(gong)(gong)(gong)等階段。
