齒輪行業簡介

一、齒輪的基本參數有哪些

齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)是(shi)指(zhi)輪(lun)(lun)緣(yuan)上有(you)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)連續嚙合傳遞運動和(he)(he)動力(li)的(de)機(ji)械(xie)元(yuan)件(jian)，在(zai)機(ji)械(xie)領域，有(you)許多不(bu)同的(de)參數(shu)(shu)用來(lai)表(biao)達(da)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)各種(zhong)性能，基(ji)本(ben)的(de)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)參數(shu)(shu)有(you)齒(chi)(chi)(chi)(chi)(chi)數(shu)(shu)z（一(yi)個(ge)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)輪(lun)(lun)齒(chi)(chi)(chi)(chi)(chi)總數(shu)(shu)）、模數(shu)(shu)m（相(xiang)鄰兩輪(lun)(lun)齒(chi)(chi)(chi)(chi)(chi)同側(ce)齒(chi)(chi)(chi)(chi)(chi)廓(kuo)間(jian)的(de)齒(chi)(chi)(chi)(chi)(chi)距p與(yu)(yu)圓周率π的(de)比值）、分度圓直徑(jing)(jing)d（直徑(jing)(jing)為模數(shu)(shu)乘以齒(chi)(chi)(chi)(chi)(chi)數(shu)(shu)的(de)乘積的(de)圓）、壓(ya)力(li)角α（兩齒(chi)(chi)(chi)(chi)(chi)廓(kuo)曲線的(de)公法(fa)線與(yu)(yu)兩節圓的(de)公切線所(suo)夾的(de)銳角）、齒(chi)(chi)(chi)(chi)(chi)高和(he)(he)齒(chi)(chi)(chi)(chi)(chi)厚(hou)等，其中(zhong)齒(chi)(chi)(chi)(chi)(chi)數(shu)(shu)和(he)(he)模數(shu)(shu)是(shi)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)最重(zhong)要的(de)參數(shu)(shu)。

二、齒輪傳動的特點

齒(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)是(shi)機(ji)械工(gong)程學的(de)(de)一個專業術(shu)語，是(shi)指利用(yong)兩齒(chi)(chi)輪(lun)的(de)(de)輪(lun)齒(chi)(chi)相(xiang)互嚙合傳(chuan)(chuan)(chuan)遞動(dong)力和運動(dong)的(de)(de)機(ji)械傳(chuan)(chuan)(chuan)動(dong)，也是(shi)應用(yong)最廣(guang)泛的(de)(de)一種(zhong)機(ji)械傳(chuan)(chuan)(chuan)動(dong)方式，有圓柱(zhu)齒(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)、錐齒(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)、行(xing)星齒(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)等多種(zhong)。齒(chi)(chi)輪(lun)傳(chuan)(chuan)(chuan)動(dong)的(de)(de)特點是(shi)傳(chuan)(chuan)(chuan)動(dong)精度高、適用(yong)范圍(wei)廣(guang)、傳(chuan)(chuan)(chuan)動(dong)效(xiao)率高、使用(yong)壽(shou)命長，不過同(tong)時齒(chi)(chi)輪(lun)的(de)(de)使用(yong)成本、制造(zao)和安裝(zhuang)的(de)(de)要求較高，對于工(gong)作(zuo)的(de)(de)環境條件要求也比較嚴格，且屬于剛性傳(chuan)(chuan)(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)輪是許多(duo)機械設(she)備(bei)的核心傳動部(bu)件(jian)，其(qi)加工(gong)(gong)(gong)質量的優(you)劣對(dui)機械設(she)備(bei)的穩定性(xing)和可靠性(xing)影響巨大，一般齒(chi)(chi)(chi)輪加工(gong)(gong)(gong)的類型有銑齒(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)齒(chi)(chi)(chi)輪的工(gong)(gong)(gong)藝過程主要包(bao)括毛坯處理、齒(chi)(chi)(chi)坯加工(gong)(gong)(gong)、齒(chi)(chi)(chi)形(xing)加工(gong)(gong)(gong)、熱(re)處理、齒(chi)(chi)(chi)形(xing)精加工(gong)(gong)(gong)、齒(chi)(chi)(chi)端加工(gong)(gong)(gong)等階段。
