齒輪行業簡介

一、齒輪的基本參數有哪些

齒(chi)(chi)(chi)(chi)輪(lun)(lun)是指輪(lun)(lun)緣上(shang)有(you)齒(chi)(chi)(chi)(chi)輪(lun)(lun)連續嚙合傳遞運動和(he)(he)動力的(de)(de)(de)機(ji)械元件，在機(ji)械領域，有(you)許(xu)多不同的(de)(de)(de)參(can)(can)數(shu)用來表達齒(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)(de)(de)各(ge)種性能，基本的(de)(de)(de)齒(chi)(chi)(chi)(chi)輪(lun)(lun)參(can)(can)數(shu)有(you)齒(chi)(chi)(chi)(chi)數(shu)z（一(yi)個齒(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)(de)(de)輪(lun)(lun)齒(chi)(chi)(chi)(chi)總數(shu)）、模數(shu)m（相(xiang)鄰兩(liang)(liang)輪(lun)(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(ju)p與圓周率π的(de)(de)(de)比值）、分(fen)度圓直(zhi)徑d（直(zhi)徑為模數(shu)乘以齒(chi)(chi)(chi)(chi)數(shu)的(de)(de)(de)乘積的(de)(de)(de)圓）、壓力角α（兩(liang)(liang)齒(chi)(chi)(chi)(chi)廓(kuo)曲線(xian)(xian)的(de)(de)(de)公法(fa)線(xian)(xian)與兩(liang)(liang)節(jie)圓的(de)(de)(de)公切線(xian)(xian)所(suo)夾的(de)(de)(de)銳角）、齒(chi)(chi)(chi)(chi)高和(he)(he)齒(chi)(chi)(chi)(chi)厚等，其中(zhong)齒(chi)(chi)(chi)(chi)數(shu)和(he)(he)模數(shu)是齒(chi)(chi)(chi)(chi)輪(lun)(lun)最(zui)重要的(de)(de)(de)參(can)(can)數(shu)。

二、齒輪傳動的特點

齒(chi)輪(lun)傳(chuan)動(dong)(dong)是(shi)(shi)(shi)機械工(gong)程學的(de)一(yi)個專業術語(yu)，是(shi)(shi)(shi)指利用(yong)(yong)(yong)兩(liang)齒(chi)輪(lun)的(de)輪(lun)齒(chi)相互嚙合傳(chuan)遞動(dong)(dong)力和(he)(he)運動(dong)(dong)的(de)機械傳(chuan)動(dong)(dong)，也(ye)(ye)是(shi)(shi)(shi)應用(yong)(yong)(yong)最廣泛的(de)一(yi)種(zhong)機械傳(chuan)動(dong)(dong)方(fang)式，有圓柱齒(chi)輪(lun)傳(chuan)動(dong)(dong)、錐(zhui)齒(chi)輪(lun)傳(chuan)動(dong)(dong)、行星齒(chi)輪(lun)傳(chuan)動(dong)(dong)等(deng)多種(zhong)。齒(chi)輪(lun)傳(chuan)動(dong)(dong)的(de)特點是(shi)(shi)(shi)傳(chuan)動(dong)(dong)精度高、適用(yong)(yong)(yong)范圍(wei)廣、傳(chuan)動(dong)(dong)效(xiao)率高、使用(yong)(yong)(yong)壽(shou)命長(chang)，不(bu)過同時齒(chi)輪(lun)的(de)使用(yong)(yong)(yong)成本、制(zhi)造和(he)(he)安裝的(de)要求(qiu)較高，對于(yu)工(gong)作的(de)環境條件要求(qiu)也(ye)(ye)比較嚴(yan)格，且屬(shu)于(yu)剛性傳(chuan)動(dong)(dong)，減振性和(he)(he)抗沖擊性都不(bu)太(tai)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)輪是許(xu)多(duo)機(ji)械(xie)設備(bei)的核心傳動部件(jian)，其加工(gong)(gong)質量(liang)的優劣對機(ji)械(xie)設備(bei)的穩(wen)定性和可靠性影響巨大，一般(ban)齒(chi)(chi)(chi)(chi)輪加工(gong)(gong)的類型有銑齒(chi)(chi)(chi)(chi)、磨(mo)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)輪的工(gong)(gong)藝過程主要包括毛坯處理(li)、齒(chi)(chi)(chi)(chi)坯加工(gong)(gong)、齒(chi)(chi)(chi)(chi)形加工(gong)(gong)、熱(re)處理(li)、齒(chi)(chi)(chi)(chi)形精加工(gong)(gong)、齒(chi)(chi)(chi)(chi)端加工(gong)(gong)等(deng)階段。
