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)是指輪(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動力(li)的(de)(de)(de)(de)機械元件，在機械領域，有(you)許多不同的(de)(de)(de)(de)參數(shu)(shu)用(yong)來表達齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)(de)(de)(de)各種性(xing)能，基本的(de)(de)(de)(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（一個(ge)齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)的(de)(de)(de)(de)輪(lun)(lun)齒(chi)(chi)(chi)(chi)(chi)總數(shu)(shu)）、模(mo)數(shu)(shu)m（相鄰兩(liang)輪(lun)(lun)齒(chi)(chi)(chi)(chi)(chi)同側齒(chi)(chi)(chi)(chi)(chi)廓間的(de)(de)(de)(de)齒(chi)(chi)(chi)(chi)(chi)距(ju)p與(yu)圓(yuan)(yuan)周率(lv)π的(de)(de)(de)(de)比(bi)值）、分(fen)度圓(yuan)(yuan)直徑(jing)d（直徑(jing)為模(mo)數(shu)(shu)乘以齒(chi)(chi)(chi)(chi)(chi)數(shu)(shu)的(de)(de)(de)(de)乘積的(de)(de)(de)(de)圓(yuan)(yuan)）、壓力(li)角α（兩(liang)齒(chi)(chi)(chi)(chi)(chi)廓曲線的(de)(de)(de)(de)公(gong)法線與(yu)兩(liang)節(jie)圓(yuan)(yuan)的(de)(de)(de)(de)公(gong)切線所夾的(de)(de)(de)(de)銳角）、齒(chi)(chi)(chi)(chi)(chi)高和齒(chi)(chi)(chi)(chi)(chi)厚(hou)等，其中齒(chi)(chi)(chi)(chi)(chi)數(shu)(shu)和模(mo)數(shu)(shu)是齒(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)最重要的(de)(de)(de)(de)參數(shu)(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)是(shi)機械(xie)工程(cheng)學的(de)一個(ge)專(zhuan)業(ye)術語，是(shi)指利用(yong)兩齒(chi)(chi)輪(lun)(lun)(lun)(lun)的(de)輪(lun)(lun)(lun)(lun)齒(chi)(chi)相互嚙合傳(chuan)(chuan)(chuan)(chuan)遞動(dong)(dong)力和(he)運動(dong)(dong)的(de)機械(xie)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)，也(ye)是(shi)應(ying)用(yong)最廣泛的(de)一種(zhong)機械(xie)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)方式，有(you)圓柱齒(chi)(chi)輪(lun)(lun)(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、錐齒(chi)(chi)輪(lun)(lun)(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)、行星齒(chi)(chi)輪(lun)(lun)(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)等多種(zhong)。齒(chi)(chi)輪(lun)(lun)(lun)(lun)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)的(de)特點是(shi)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)精度高、適用(yong)范圍廣、傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)效率高、使用(yong)壽命長(chang)，不過同時齒(chi)(chi)輪(lun)(lun)(lun)(lun)的(de)使用(yong)成本(ben)、制(zhi)造(zao)和(he)安裝的(de)要求(qiu)(qiu)較(jiao)高，對于工作的(de)環境(jing)條件(jian)要求(qiu)(qiu)也(ye)比較(jiao)嚴格(ge)，且屬于剛性(xing)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)，減(jian)振性(xing)和(he)抗沖擊(ji)性(xing)都不太理(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)輪(lun)是許多機械設(she)備的核心傳動部件，其加(jia)(jia)工(gong)(gong)質量的優劣對機械設(she)備的穩定性和可(ke)靠性影響(xiang)巨大，一(yi)般(ban)齒(chi)(chi)輪(lun)加(jia)(jia)工(gong)(gong)的類型有銑齒(chi)(chi)、磨齒(chi)(chi)、滾(gun)齒(chi)(chi)、插(cha)齒(chi)(chi)、剃(ti)齒(chi)(chi)、珩齒(chi)(chi)六種(zhong)，加(jia)(jia)工(gong)(gong)齒(chi)(chi)輪(lun)的工(gong)(gong)藝過程主要包括毛坯處理、齒(chi)(chi)坯加(jia)(jia)工(gong)(gong)、齒(chi)(chi)形加(jia)(jia)工(gong)(gong)、熱處理、齒(chi)(chi)形精加(jia)(jia)工(gong)(gong)、齒(chi)(chi)端加(jia)(jia)工(gong)(gong)等階段。
