齒輪行業簡介

一、齒輪的基本參數有哪些

齒(chi)(chi)輪(lun)(lun)是(shi)指輪(lun)(lun)緣上有齒(chi)(chi)輪(lun)(lun)連續嚙合傳遞運動(dong)和動(dong)力的(de)機械元(yuan)件(jian)，在機械領域，有許多不同的(de)參(can)數(shu)(shu)用來(lai)表達齒(chi)(chi)輪(lun)(lun)的(de)各種性能，基本(ben)的(de)齒(chi)(chi)輪(lun)(lun)參(can)數(shu)(shu)有齒(chi)(chi)數(shu)(shu)z（一個(ge)齒(chi)(chi)輪(lun)(lun)的(de)輪(lun)(lun)齒(chi)(chi)總數(shu)(shu)）、模數(shu)(shu)m（相鄰(lin)兩輪(lun)(lun)齒(chi)(chi)同側(ce)齒(chi)(chi)廓(kuo)間的(de)齒(chi)(chi)距p與(yu)圓(yuan)周率π的(de)比(bi)值）、分度圓(yuan)直(zhi)徑d（直(zhi)徑為模數(shu)(shu)乘(cheng)以齒(chi)(chi)數(shu)(shu)的(de)乘(cheng)積(ji)的(de)圓(yuan)）、壓力角α（兩齒(chi)(chi)廓(kuo)曲線(xian)(xian)的(de)公(gong)法(fa)線(xian)(xian)與(yu)兩節(jie)圓(yuan)的(de)公(gong)切線(xian)(xian)所夾(jia)的(de)銳角）、齒(chi)(chi)高和齒(chi)(chi)厚等(deng)，其中齒(chi)(chi)數(shu)(shu)和模數(shu)(shu)是(shi)齒(chi)(chi)輪(lun)(lun)最重要的(de)參(can)數(shu)(shu)。

二、齒輪傳動的特點

齒(chi)(chi)輪(lun)(lun)(lun)傳(chuan)動(dong)是(shi)機械工程(cheng)學的(de)(de)(de)一個專(zhuan)業術語，是(shi)指(zhi)利用(yong)(yong)兩齒(chi)(chi)輪(lun)(lun)(lun)的(de)(de)(de)輪(lun)(lun)(lun)齒(chi)(chi)相互嚙合傳(chuan)遞(di)動(dong)力和運動(dong)的(de)(de)(de)機械傳(chuan)動(dong)，也是(shi)應用(yong)(yong)最廣(guang)(guang)泛的(de)(de)(de)一種機械傳(chuan)動(dong)方式，有圓柱齒(chi)(chi)輪(lun)(lun)(lun)傳(chuan)動(dong)、錐(zhui)齒(chi)(chi)輪(lun)(lun)(lun)傳(chuan)動(dong)、行星齒(chi)(chi)輪(lun)(lun)(lun)傳(chuan)動(dong)等多種。齒(chi)(chi)輪(lun)(lun)(lun)傳(chuan)動(dong)的(de)(de)(de)特點是(shi)傳(chuan)動(dong)精(jing)度高、適用(yong)(yong)范圍(wei)廣(guang)(guang)、傳(chuan)動(dong)效率高、使用(yong)(yong)壽命長，不過同時齒(chi)(chi)輪(lun)(lun)(lun)的(de)(de)(de)使用(yong)(yong)成本、制造(zao)和安裝的(de)(de)(de)要求較(jiao)高，對于工作的(de)(de)(de)環(huan)境條件要求也比較(jiao)嚴格，且(qie)屬于剛(gang)性傳(chuan)動(dong)，減振性和抗沖擊性都不太理想。

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(xu)多機械設(she)備(bei)(bei)的(de)核(he)心傳(chuan)動部件，其加工(gong)(gong)(gong)(gong)質量的(de)優(you)劣對機械設(she)備(bei)(bei)的(de)穩(wen)定性(xing)和可靠性(xing)影響巨(ju)大(da)，一(yi)般齒(chi)(chi)(chi)輪(lun)(lun)加工(gong)(gong)(gong)(gong)的(de)類型有銑齒(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，加工(gong)(gong)(gong)(gong)齒(chi)(chi)(chi)輪(lun)(lun)的(de)工(gong)(gong)(gong)(gong)藝(yi)過(guo)程主要包括毛坯(pi)處(chu)理、齒(chi)(chi)(chi)坯(pi)加工(gong)(gong)(gong)(gong)、齒(chi)(chi)(chi)形加工(gong)(gong)(gong)(gong)、熱處(chu)理、齒(chi)(chi)(chi)形精加工(gong)(gong)(gong)(gong)、齒(chi)(chi)(chi)端加工(gong)(gong)(gong)(gong)等(deng)階段。
