JRTRXF57減(jian)(jian)速(su)(su)器(qi)型號大全齒(chi)輪減(jian)(jian)速(su)(su)機設(she)計(ji)(ji)常見(jian)問(wen)題剖析。在齒(chi)輪減(jian)(jian)速(su)(su)機的(de)(de)(de)(de)(de)設(she)計(ji)(ji)中，有部分(fen)零(ling)(ling)件(jian)可由強(qiang)度(du)(du)條件(jian)或剛(gang)度(du)(du)條件(jian)確定(ding)(ding)零(ling)(ling)件(jian)的(de)(de)(de)(de)(de)基本尺(chi)寸(cun)(cun)，然(ran)后通(tong)過草圖(tu)設(she)計(ji)(ji)決定(ding)(ding)其具體結(jie)(jie)構(gou)和(he)尺(chi)寸(cun)(cun)（如(ru)齒(chi)輪）；而另(ling)有部分(fen)零(ling)(ling)件(jian)（如(ru)軸）則需(xu)要(yao)先經(jing)初(chu)(chu)步計(ji)(ji)算(suan)和(he)繪制草圖(tu)，得(de)出初(chu)(chu)步符合(he)設(she)計(ji)(ji)條件(jian)的(de)(de)(de)(de)(de)基本結(jie)(jie)構(gou)尺(chi)寸(cun)(cun)，然(ran)后進行必要(yao)的(de)(de)(de)(de)(de)校核計(ji)(ji)算(suan)，根據計(ji)(ji)算(suan)結(jie)(jie)果，再對(dui)結(jie)(jie)構(gou)和(he)尺(chi)寸(cun)(cun)進行修改(gai)，甚至(zhi)反(fan)復多次(ci)修改(gai)。零(ling)(ling)件(jian)尺(chi)寸(cun)(cun)不(bu)可能完全由理論(lun)計(ji)(ji)算(suan)確定(ding)(ding)，而是要(yao)綜合(he)考(kao)慮(lv)齒(chi)輪減(jian)(jian)速(su)(su)電機結(jie)(jie)構(gou)和(he)其它各方面的(de)(de)(de)(de)(de)要(yao)求才能決定(ding)(ding)。零(ling)(ling)件(jian)的(de)(de)(de)(de)(de)設(she)計(ji)(ji)過程是個綜合(he)考(kao)慮(lv)強(qiang)度(du)(du)、結(jie)(jie)構(gou)、裝(zhuang)配和(he)工(gong)藝等因素的(de)(de)(de)(de)(de)過程，理論(lun)計(ji)(ji)算(suan)只是為(wei)合(he)理確定(ding)(ding)零(ling)(ling)件(jian)尺(chi)寸(cun)(cun)提供了某些方面（如(ru)強(qiang)度(du)(du)、剛(gang)度(du)(du)）的(de)(de)(de)(de)(de)依(yi)據。此外，齒(chi)輪減(jian)(jian)速(su)(su)機的(de)(de)(de)(de)(de)設(she)計(ji)(ji)時還要(yao)盡量(liang)使用標準件(jian)。

齒(chi)(chi)輪(lun)(lun)(lun)減(jian)速(su)(su)(su)機設(she)計中電(dian)機的(de)選擇：低速(su)(su)(su)電(dian)動(dong)(dong)(dong)(dong)(dong)(dong)機的(de)數多，結構尺(chi)寸及重量大，價格較貴，但(dan)可使(shi)(shi)齒(chi)(chi)輪(lun)(lun)(lun)減(jian)速(su)(su)(su)馬達的(de)總(zong)(zong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)及尺(chi)寸減(jian)小，而高速(su)(su)(su)電(dian)動(dong)(dong)(dong)(dong)(dong)(dong)機正好與低速(su)(su)(su)電(dian)動(dong)(dong)(dong)(dong)(dong)(dong)機情(qing)況相反(fan)，所以(yi)選擇電(dian)動(dong)(dong)(dong)(dong)(dong)(dong)機轉速(su)(su)(su)時應(ying)綜(zong)合考慮、分析(xi)比(bi)較電(dian)動(dong)(dong)(dong)(dong)(dong)(dong)機和傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)系統的(de)性能、尺(chi)寸、重量和價格等因素，使(shi)(shi)整個設(she)計盡量做到既合理(li)又經濟。齒(chi)(chi)輪(lun)(lun)(lun)減(jian)速(su)(su)(su)電(dian)機總(zong)(zong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)為(wei)各傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)的(de)連(lian)乘積(ji)，要合理(li)地分配(pei)(pei)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)，就需要齒(chi)(chi)輪(lun)(lun)(lun)減(jian)速(su)(su)(su)機各傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)應(ying)盡量在各自推薦(jian)范圍內，傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)零件之間不發生干涉，傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)裝置的(de)外(wai)廓(kuo)盡量緊湊(cou)，各大齒(chi)(chi)輪(lun)(lun)(lun)直徑(jing)接近以(yi)便于潤滑。上述傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)分配(pei)(pei)只(zhi)是初步(bu)的(de)數值，在傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)零件設(she)計時，由于帶輪(lun)(lun)(lun)基準(zhun)直徑(jing)要標準(zhun)化，齒(chi)(chi)輪(lun)(lun)(lun)齒(chi)(chi)數要取整，必然會使(shi)(shi)實際傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)變(bian)化。在齒(chi)(chi)輪(lun)(lun)(lun)減(jian)速(su)(su)(su)電(dian)機所有(you)的(de)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)零件設(she)計計算(suan)完成后，要保證實際總(zong)(zong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)與要求的(de)總(zong)(zong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)比(bi)相對誤差(cha)限制在正負4%范圍內。

齒(chi)(chi)(chi)(chi)(chi)(chi)輪減(jian)速機中齒(chi)(chi)(chi)(chi)(chi)(chi)輪強(qiang)度(du)條件(jian)是根據齒(chi)(chi)(chi)(chi)(chi)(chi)輪可能發生的(de)失效形(xing)式(shi)(shi)決定(ding)的(de)。在閉式(shi)(shi)傳動(dong)中，當齒(chi)(chi)(chi)(chi)(chi)(chi)面(mian)(mian)硬(ying)度(du)小于(yu)等(deng)于(yu)350時(shi)，輪齒(chi)(chi)(chi)(chi)(chi)(chi)的(de)失效形(xing)式(shi)(shi)主要(yao)是齒(chi)(chi)(chi)(chi)(chi)(chi)面(mian)(mian)點蝕，此時(shi)應按(an)齒(chi)(chi)(chi)(chi)(chi)(chi)面(mian)(mian)接觸(chu)疲(pi)勞(lao)強(qiang)度(du)條件(jian)設計，再校核輪齒(chi)(chi)(chi)(chi)(chi)(chi)的(de)彎曲(qu)疲(pi)勞(lao)強(qiang)度(du)；當齒(chi)(chi)(chi)(chi)(chi)(chi)面(mian)(mian)硬(ying)度(du)大于(yu)350時(shi)，輪齒(chi)(chi)(chi)(chi)(chi)(chi)的(de)失效形(xing)式(shi)(shi)主要(yao)是折斷，應按(an)輪齒(chi)(chi)(chi)(chi)(chi)(chi)的(de)彎曲(qu)疲(pi)勞(lao)強(qiang)度(du)設計，再校核其(qi)齒(chi)(chi)(chi)(chi)(chi)(chi)面(mian)(mian)接觸(chu)強(qiang)度(du)。

齒(chi)輪減(jian)速機中(zhong)齒(chi)輪的(de)嚙合尺(chi)寸(cun)（齒(chi)圓(yuan)(yuan)和(he)分度(du)(du)圓(yuan)(yuan)直(zhi)徑、螺旋角等）必(bi)須精(jing)確，般應(ying)準(zhun)(zhun)確到(dao)小數點后2-3位，角度(du)(du)要精(jing)確到(dao)秒，結構尺(chi)寸(cun)均(jun)應(ying)圓(yuan)(yuan)整，有些還(huan)要標準(zhun)(zhun)化，以方便制造和(he)測量。齒(chi)輪減(jian)速電機設計中(zhong)，鍵(jian)的(de)寬度(du)(du)和(he)高度(du)(du)按照軸的(de)直(zhi)徑由標準(zhun)(zhun)選定，鍵(jian)的(de)長(chang)(chang)度(du)(du)根(gen)據(ju)輪轂(gu)長(chang)(chang)度(du)(du)來定，然(ran)后按擠(ji)壓強(qiang)度(du)(du)條(tiao)件(jian)進行校核，如(ru)果強(qiang)度(du)(du)不夠(gou)，可采用(yong)增加鍵(jian)的(de)長(chang)(chang)度(du)(du)、增大軸徑、改用(yong)雙鍵(jian)等方法，以滿(man)足(zu)強(qiang)度(du)(du)要求。圓(yuan)(yuan)頭平鍵(jian)的(de)鍵(jian)槽(cao)(cao)(cao)是用(yong)鍵(jian)槽(cao)(cao)(cao)銑刀銑出來的(de)，鍵(jian)槽(cao)(cao)(cao)兩(liang)(liang)端(duan) 各(ge)有個半圓(yuan)(yuan)柱(zhu)面(mian)，方頭平鍵(jian)的(de)鍵(jian)槽(cao)(cao)(cao)是用(yong)盤銑刀銑出來的(de)，鍵(jian)槽(cao)(cao)(cao)兩(liang)(liang)端(duan)也各(ge)有段(duan)過渡圓(yuan)(yuan)柱(zhu)面(mian)。對于同樣長(chang)(chang)度(du)(du)的(de)圓(yuan)(yuan)頭平鍵(jian)鍵(jian)槽(cao)(cao)(cao)和(he)方頭平鍵(jian)鍵(jian)槽(cao)(cao)(cao)，裝在鍵(jian)槽(cao)(cao)(cao)中(zhong)的(de)鍵(jian)的(de)工作長(chang)(chang)度(du)(du)是差不多的(de)。
