一、齒輪的基本參數有哪些

齒(chi)(chi)(chi)(chi)輪(lun)是指輪(lun)緣(yuan)上有齒(chi)(chi)(chi)(chi)輪(lun)連續嚙合傳遞運動(dong)(dong)和(he)動(dong)(dong)力的(de)機(ji)械(xie)元件，在機(ji)械(xie)領域(yu)，有許多不同(tong)(tong)的(de)參(can)數(shu)用來表達齒(chi)(chi)(chi)(chi)輪(lun)的(de)各種性能，基本(ben)的(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)輪(lun)齒(chi)(chi)(chi)(chi)總數(shu)）、模(mo)數(shu)m（相鄰兩輪(lun)齒(chi)(chi)(chi)(chi)同(tong)(tong)側(ce)齒(chi)(chi)(chi)(chi)廓(kuo)間的(de)齒(chi)(chi)(chi)(chi)距p與(yu)圓(yuan)周率π的(de)比值(zhi)）、分(fen)度(du)圓(yuan)直(zhi)徑(jing)d（直(zhi)徑(jing)為模(mo)數(shu)乘以齒(chi)(chi)(chi)(chi)數(shu)的(de)乘積(ji)的(de)圓(yuan)）、壓力角α（兩齒(chi)(chi)(chi)(chi)廓(kuo)曲線的(de)公法(fa)線與(yu)兩節(jie)圓(yuan)的(de)公切(qie)線所夾的(de)銳角）、齒(chi)(chi)(chi)(chi)高(gao)和(he)齒(chi)(chi)(chi)(chi)厚等，其中(zhong)齒(chi)(chi)(chi)(chi)數(shu)和(he)模(mo)數(shu)是齒(chi)(chi)(chi)(chi)輪(lun)最重(zhong)要的(de)參(can)數(shu)。

二、齒輪傳動的特點

齒(chi)(chi)輪(lun)(lun)(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)是機(ji)(ji)械(xie)工程學的(de)(de)一(yi)個專業術語，是指利用(yong)兩齒(chi)(chi)輪(lun)(lun)(lun)(lun)的(de)(de)輪(lun)(lun)(lun)(lun)齒(chi)(chi)相(xiang)互嚙合(he)傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)(dong)(dong)力和運動(dong)(dong)(dong)(dong)的(de)(de)機(ji)(ji)械(xie)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，也是應用(yong)最廣泛(fan)的(de)(de)一(yi)種機(ji)(ji)械(xie)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)方式(shi)，有圓(yuan)柱(zhu)齒(chi)(chi)輪(lun)(lun)(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、錐(zhui)齒(chi)(chi)輪(lun)(lun)(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)、行(xing)星齒(chi)(chi)輪(lun)(lun)(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)等多種。齒(chi)(chi)輪(lun)(lun)(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)的(de)(de)特(te)點(dian)是傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)精度(du)高(gao)、適用(yong)范圍廣、傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)效率高(gao)、使用(yong)壽命長，不過(guo)同時齒(chi)(chi)輪(lun)(lun)(lun)(lun)的(de)(de)使用(yong)成本、制(zhi)造和安(an)裝的(de)(de)要求(qiu)較高(gao)，對于工作的(de)(de)環境條(tiao)件要求(qiu)也比(bi)較嚴格，且屬于剛性(xing)(xing)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，減振性(xing)(xing)和抗沖擊性(xing)(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(lun)是許(xu)多機械設(she)備的(de)(de)核心傳(chuan)動部件，其加工質量的(de)(de)優劣對機械設(she)備的(de)(de)穩定性和(he)可靠性影響巨大(da)，一般齒(chi)(chi)(chi)(chi)(chi)輪(lun)加工的(de)(de)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)、插齒(chi)(chi)(chi)(chi)(chi)、剃齒(chi)(chi)(chi)(chi)(chi)、珩齒(chi)(chi)(chi)(chi)(chi)六種，加工齒(chi)(chi)(chi)(chi)(chi)輪(lun)的(de)(de)工藝過程主要包括毛坯處(chu)(chu)理、齒(chi)(chi)(chi)(chi)(chi)坯加工、齒(chi)(chi)(chi)(chi)(chi)形加工、熱(re)處(chu)(chu)理、齒(chi)(chi)(chi)(chi)(chi)形精加工、齒(chi)(chi)(chi)(chi)(chi)端加工等階段。
