一、齒輪的基本參數有哪些

齒(chi)(chi)(chi)輪是指(zhi)輪緣上有齒(chi)(chi)(chi)輪連續嚙合傳遞運(yun)動(dong)和(he)動(dong)力的(de)(de)機械元件，在機械領域，有許多不同的(de)(de)參數(shu)(shu)用來表達齒(chi)(chi)(chi)輪的(de)(de)各種性能，基本的(de)(de)齒(chi)(chi)(chi)輪參數(shu)(shu)有齒(chi)(chi)(chi)數(shu)(shu)z（一個齒(chi)(chi)(chi)輪的(de)(de)輪齒(chi)(chi)(chi)總(zong)數(shu)(shu)）、模(mo)(mo)數(shu)(shu)m（相鄰兩輪齒(chi)(chi)(chi)同側齒(chi)(chi)(chi)廓間的(de)(de)齒(chi)(chi)(chi)距p與圓(yuan)(yuan)周率π的(de)(de)比值）、分度圓(yuan)(yuan)直徑d（直徑為模(mo)(mo)數(shu)(shu)乘(cheng)以(yi)齒(chi)(chi)(chi)數(shu)(shu)的(de)(de)乘(cheng)積的(de)(de)圓(yuan)(yuan)）、壓力角α（兩齒(chi)(chi)(chi)廓曲線的(de)(de)公(gong)法線與兩節(jie)圓(yuan)(yuan)的(de)(de)公(gong)切(qie)線所夾(jia)的(de)(de)銳角）、齒(chi)(chi)(chi)高和(he)齒(chi)(chi)(chi)厚等，其中齒(chi)(chi)(chi)數(shu)(shu)和(he)模(mo)(mo)數(shu)(shu)是齒(chi)(chi)(chi)輪最重(zhong)要的(de)(de)參數(shu)(shu)。

二、齒輪傳動的特點

齒(chi)(chi)輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)是(shi)(shi)機械工(gong)程學(xue)的(de)一個專業術語，是(shi)(shi)指利用(yong)(yong)兩(liang)齒(chi)(chi)輪(lun)的(de)輪(lun)齒(chi)(chi)相互嚙(nie)合(he)傳(chuan)遞動(dong)(dong)(dong)(dong)(dong)力和運動(dong)(dong)(dong)(dong)(dong)的(de)機械傳(chuan)動(dong)(dong)(dong)(dong)(dong)，也(ye)(ye)是(shi)(shi)應用(yong)(yong)最廣泛(fan)的(de)一種(zhong)(zhong)機械傳(chuan)動(dong)(dong)(dong)(dong)(dong)方式，有圓柱齒(chi)(chi)輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)、錐齒(chi)(chi)輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)、行星齒(chi)(chi)輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)等多種(zhong)(zhong)。齒(chi)(chi)輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)的(de)特點是(shi)(shi)傳(chuan)動(dong)(dong)(dong)(dong)(dong)精度高(gao)(gao)、適用(yong)(yong)范圍廣、傳(chuan)動(dong)(dong)(dong)(dong)(dong)效率(lv)高(gao)(gao)、使(shi)用(yong)(yong)壽命長，不過同時齒(chi)(chi)輪(lun)的(de)使(shi)用(yong)(yong)成本、制(zhi)造(zao)和安裝的(de)要(yao)(yao)求較高(gao)(gao)，對于工(gong)作的(de)環境條件要(yao)(yao)求也(ye)(ye)比(bi)較嚴格，且屬(shu)于剛性(xing)傳(chuan)動(dong)(dong)(dong)(dong)(dong)，減(jian)振(zhen)性(xing)和抗沖擊性(xing)都(dou)不太理(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)(chi)輪是許(xu)多機械設備(bei)的(de)核(he)心(xin)傳(chuan)動部件(jian)，其加工(gong)(gong)質量的(de)優劣對機械設備(bei)的(de)穩定性和可靠性影響巨大，一(yi)般齒(chi)(chi)(chi)(chi)輪加工(gong)(gong)的(de)類型有銑(xian)齒(chi)(chi)(chi)(chi)、磨齒(chi)(chi)(chi)(chi)、滾齒(chi)(chi)(chi)(chi)、插齒(chi)(chi)(chi)(chi)、剃齒(chi)(chi)(chi)(chi)、珩齒(chi)(chi)(chi)(chi)六種，加工(gong)(gong)齒(chi)(chi)(chi)(chi)輪的(de)工(gong)(gong)藝過(guo)程主要包括(kuo)毛坯(pi)處理(li)、齒(chi)(chi)(chi)(chi)坯(pi)加工(gong)(gong)、齒(chi)(chi)(chi)(chi)形(xing)加工(gong)(gong)、熱處理(li)、齒(chi)(chi)(chi)(chi)形(xing)精加工(gong)(gong)、齒(chi)(chi)(chi)(chi)端加工(gong)(gong)等階段(duan)。
