JRTRXF57減(jian)速(su)器(qi)型號大全齒(chi)輪(lun)減(jian)速(su)機(ji)設計(ji)(ji)(ji)常見問題剖析。在齒(chi)輪(lun)減(jian)速(su)機(ji)的(de)(de)設計(ji)(ji)(ji)中，有(you)(you)部分零(ling)件(jian)(jian)可(ke)由強度條(tiao)件(jian)(jian)或剛度條(tiao)件(jian)(jian)確定(ding)零(ling)件(jian)(jian)的(de)(de)基(ji)本尺寸(cun)(cun)(cun)，然后(hou)通過草圖設計(ji)(ji)(ji)決定(ding)其(qi)具體結(jie)構(gou)(gou)和(he)尺寸(cun)(cun)(cun)（如齒(chi)輪(lun)）；而(er)另有(you)(you)部分零(ling)件(jian)(jian)（如軸）則(ze)需要(yao)先經初步計(ji)(ji)(ji)算(suan)和(he)繪制草圖，得(de)出(chu)初步符合(he)設計(ji)(ji)(ji)條(tiao)件(jian)(jian)的(de)(de)基(ji)本結(jie)構(gou)(gou)尺寸(cun)(cun)(cun)，然后(hou)進(jin)行必要(yao)的(de)(de)校核計(ji)(ji)(ji)算(suan)，根據計(ji)(ji)(ji)算(suan)結(jie)果，再對結(jie)構(gou)(gou)和(he)尺寸(cun)(cun)(cun)進(jin)行修改，甚至反(fan)復多次修改。零(ling)件(jian)(jian)尺寸(cun)(cun)(cun)不可(ke)能完(wan)全由理論(lun)計(ji)(ji)(ji)算(suan)確定(ding)，而(er)是要(yao)綜合(he)考(kao)慮齒(chi)輪(lun)減(jian)速(su)電(dian)機(ji)結(jie)構(gou)(gou)和(he)其(qi)它各方(fang)面的(de)(de)要(yao)求才能決定(ding)。零(ling)件(jian)(jian)的(de)(de)設計(ji)(ji)(ji)過程(cheng)是個(ge)綜合(he)考(kao)慮強度、結(jie)構(gou)(gou)、裝配(pei)和(he)工藝等因素的(de)(de)過程(cheng)，理論(lun)計(ji)(ji)(ji)算(suan)只是為合(he)理確定(ding)零(ling)件(jian)(jian)尺寸(cun)(cun)(cun)提供了某些(xie)方(fang)面（如強度、剛度）的(de)(de)依據。此外，齒(chi)輪(lun)減(jian)速(su)機(ji)的(de)(de)設計(ji)(ji)(ji)時還要(yao)盡量使用標(biao)準件(jian)(jian)。
