機(ji)(ji)(ji)器(qi)(qi)的(de)(de)(de)部件主要(yao)有動(dong)(dong)(dong)(dong)力(li)(li)源(yuan)、傳(chuan)動(dong)(dong)(dong)(dong)裝置(zhi)、執行(xing)(xing)機(ji)(ji)(ji)構、控制(zhi)(zhi)系統(tong)這(zhe)四(si)大部分(fen)組成。動(dong)(dong)(dong)(dong)力(li)(li)源(yuan)是(shi)(shi)(shi)將其(qi)(qi)他形式的(de)(de)(de)能(neng)源(yuan)轉變(bian)為機(ji)(ji)(ji)械能(neng)的(de)(de)(de)動(dong)(dong)(dong)(dong)力(li)(li)機(ji)(ji)(ji)械，如內燃(ran)機(ji)(ji)(ji)、電(dian)動(dong)(dong)(dong)(dong)機(ji)(ji)(ji)、液壓馬達(da)等，其(qi)(qi)功(gong)能(neng)提(ti)供機(ji)(ji)(ji)器(qi)(qi)工(gong)作(zuo)的(de)(de)(de)能(neng)力(li)(li)。傳(chuan)動(dong)(dong)(dong)(dong)裝置(zhi)是(shi)(shi)(shi)將動(dong)(dong)(dong)(dong)力(li)(li)源(yuan)輸出的(de)(de)(de)動(dong)(dong)(dong)(dong)力(li)(li)和(he)運動(dong)(dong)(dong)(dong)傳(chuan)遞給執行(xing)(xing)機(ji)(ji)(ji)構的(de)(de)(de)中間裝置(zhi)，其(qi)(qi)功(gong)能(neng)是(shi)(shi)(shi)傳(chuan)遞動(dong)(dong)(dong)(dong)力(li)(li)，進(jin)行(xing)(xing)增速或(huo)減速和(he)變(bian)速、改變(bian)運動(dong)(dong)(dong)(dong)形式等。執行(xing)(xing)機(ji)(ji)(ji)構是(shi)(shi)(shi)直接(jie)與工(gong)作(zuo)對(dui)象接(jie)觸的(de)(de)(de)機(ji)(ji)(ji)構，其(qi)(qi)功(gong)能(neng)是(shi)(shi)(shi)利用機(ji)(ji)(ji)械能(neng)通過機(ji)(ji)(ji)械運動(dong)(dong)(dong)(dong)來改變(bian)工(gong)作(zuo)對(dui)象的(de)(de)(de)形狀、位置(zhi)等。控制(zhi)(zhi)系統(tong)的(de)(de)(de)功(gong)能(neng)是(shi)(shi)(shi)對(dui)整個機(ji)(ji)(ji)器(qi)(qi)起(qi)控制(zhi)(zhi)作(zuo)用，以(yi)便使動(dong)(dong)(dong)(dong)力(li)(li)源(yuan)、傳(chuan)動(dong)(dong)(dong)(dong)系統(tong)和(he)執行(xing)(xing)機(ji)(ji)(ji)構彼此協調運行(xing)(xing)而完(wan)成機(ji)(ji)(ji)器(qi)(qi)上的(de)(de)(de)工(gong)作(zuo)。

直流減速電機就是一(yi)種機(ji)械的(de)(de)(de)傳動裝置，減速電(dian)(dian)機(ji)一(yi)般(ban)位于原動機(ji)和(he)(he)(he)執行機(ji)構之間，減速電(dian)(dian)機(ji)的(de)(de)(de)外廓尺寸緊湊，潤(run)滑條件良好，效(xiao)率高(gao)。使用(yong)壽(shou)命(ming)較(jiao)長，噪音小及(ji)安全可靠等特點，因此，減速電(dian)(dian)機(ji)的(de)(de)(de)應(ying)用(yong)很。目(mu)前的(de)(de)(de)減速電(dian)(dian)機(ji)已成為一(yi)種專門部件，并(bing)由廠家設(she)計和(he)(he)(he)制造，常用(yong)的(de)(de)(de)減速電(dian)(dian)機(ji)已經化(hua)，規格(ge)化(hua)和(he)(he)(he)系列(lie)化(hua)，用(yong)戶可根據各自的(de)(de)(de)工作(zuo)條件來選擇合適的(de)(de)(de)減速電(dian)(dian)機(ji)。

減(jian)(jian)(jian)(jian)(jian)(jian)速(su)(su)(su)電機(ji)的結構根(gen)據其類型(xing)和(he)(he)需求的不同(tong)(tong)而(er)不同(tong)(tong)，但一般(ban)的減(jian)(jian)(jian)(jian)(jian)(jian)速(su)(su)(su)電機(ji)都是(shi)由箱(xiang)體、軸(zhou)(zhou)(zhou)(zhou)和(he)(he)軸(zhou)(zhou)(zhou)(zhou)上零件(jian)、軸(zhou)(zhou)(zhou)(zhou)承部件(jian)、潤滑(hua)密(mi)封裝置及減(jian)(jian)(jian)(jian)(jian)(jian)速(su)(su)(su)器附件(jian)等組成。同(tong)(tong)時減(jian)(jian)(jian)(jian)(jian)(jian)速(su)(su)(su)電機(ji)的類型(xing)很多，減(jian)(jian)(jian)(jian)(jian)(jian)速(su)(su)(su)電機(ji)可按(an)傳動(dong)條件(jian)的不同(tong)(tong)分為(wei)齒(chi)輪減(jian)(jian)(jian)(jian)(jian)(jian)速(su)(su)(su)電機(ji)、蝸桿減(jian)(jian)(jian)(jian)(jian)(jian)速(su)(su)(su)電機(ji)、蝸桿—齒(chi)輪減(jian)(jian)(jian)(jian)(jian)(jian)速(su)(su)(su)電機(ji)和(he)(he)行星齒(chi)輪減(jian)(jian)(jian)(jian)(jian)(jian)速(su)(su)(su)電機(ji)；而(er)按(an)減(jian)(jian)(jian)(jian)(jian)(jian)速(su)(su)(su)電機(ji)的級數(shu)可分為(wei)單級減(jian)(jian)(jian)(jian)(jian)(jian)速(su)(su)(su)電機(ji)、雙級減(jian)(jian)(jian)(jian)(jian)(jian)速(su)(su)(su)電機(ji)和(he)(he)多級減(jian)(jian)(jian)(jian)(jian)(jian)速(su)(su)(su)電機(ji)；而(er)按(an)軸(zhou)(zhou)(zhou)(zhou)在空(kong)間的相對位置，可分為(wei)臥式減(jian)(jian)(jian)(jian)(jian)(jian)速(su)(su)(su)電機(ji)和(he)(he)立式減(jian)(jian)(jian)(jian)(jian)(jian)速(su)(su)(su)電機(ji)。

??直流減速(su)電機(ji)的(de)(de)箱(xiang)體設(she)計一般要(yao)考慮(lv)到減速(su)電機(ji)箱(xiang)體的(de)(de)剛度、密(mi)封(feng)、潤滑以及工(gong)(gong)藝性(xing)等因素。減速(su)電機(ji)的(de)(de)箱(xiang)體必須要(yao)有足夠的(de)(de)剛度，不允許在(zai)工(gong)(gong)作過(guo)程(cheng)中產生過(guo)大的(de)(de)變形(xing)而影(ying)響到傳(chuan)動精度。為了減速(su)電機(ji)箱(xiang)體的(de)(de)剛度，箱(xiang)體應有足夠的(de)(de)壁厚(hou)，并在(zai)軸承座附件加筋(jin)板。
