機(ji)器(qi)的(de)部件主要有動(dong)(dong)(dong)(dong)力(li)(li)源、傳動(dong)(dong)(dong)(dong)裝(zhuang)置、執行機(ji)構(gou)(gou)(gou)、控制(zhi)系統(tong)這(zhe)四大(da)部分組(zu)成(cheng)。動(dong)(dong)(dong)(dong)力(li)(li)源是將其(qi)他形(xing)式的(de)能(neng)源轉變為機(ji)械能(neng)的(de)動(dong)(dong)(dong)(dong)力(li)(li)機(ji)械，如內(nei)燃機(ji)、電動(dong)(dong)(dong)(dong)機(ji)、液壓馬達(da)等，其(qi)功(gong)能(neng)提供機(ji)器(qi)工作(zuo)的(de)能(neng)力(li)(li)。傳動(dong)(dong)(dong)(dong)裝(zhuang)置是將動(dong)(dong)(dong)(dong)力(li)(li)源輸出的(de)動(dong)(dong)(dong)(dong)力(li)(li)和(he)運(yun)動(dong)(dong)(dong)(dong)傳遞(di)(di)給執行機(ji)構(gou)(gou)(gou)的(de)中間裝(zhuang)置，其(qi)功(gong)能(neng)是傳遞(di)(di)動(dong)(dong)(dong)(dong)力(li)(li)，進行增速(su)(su)或(huo)減速(su)(su)和(he)變速(su)(su)、改變運(yun)動(dong)(dong)(dong)(dong)形(xing)式等。執行機(ji)構(gou)(gou)(gou)是直(zhi)接與工作(zuo)對象接觸的(de)機(ji)構(gou)(gou)(gou)，其(qi)功(gong)能(neng)是利用機(ji)械能(neng)通過機(ji)械運(yun)動(dong)(dong)(dong)(dong)來(lai)改變工作(zuo)對象的(de)形(xing)狀(zhuang)、位置等。控制(zhi)系統(tong)的(de)功(gong)能(neng)是對整個機(ji)器(qi)起控制(zhi)作(zuo)用，以(yi)便使動(dong)(dong)(dong)(dong)力(li)(li)源、傳動(dong)(dong)(dong)(dong)系統(tong)和(he)執行機(ji)構(gou)(gou)(gou)彼(bi)此協調運(yun)行而完成(cheng)機(ji)器(qi)上的(de)工作(zuo)。

直流減速電機就是一種機械的傳動裝置，減速電機一般位于原動機和執行機構之間，減速電機的外廓尺寸緊湊，潤滑條件良好，效率高。使用壽命較長，噪音小及安全可靠等特點，因此，減速電機的應用很。目前的減速電機已成為一種專門部件，并由廠家設計和制造，常用的減速電機已經化，規格化和系列化，用戶可根據各自的工作條件來選擇合適的減速電機。

減(jian)(jian)(jian)速(su)(su)電(dian)(dian)機(ji)(ji)的(de)結構根據其(qi)類型和(he)需求的(de)不同(tong)(tong)而(er)不同(tong)(tong)，但一般的(de)減(jian)(jian)(jian)速(su)(su)電(dian)(dian)機(ji)(ji)都是由(you)箱體、軸和(he)軸上零件(jian)、軸承(cheng)部件(jian)、潤滑密封裝置(zhi)及(ji)減(jian)(jian)(jian)速(su)(su)器(qi)附件(jian)等組成(cheng)。同(tong)(tong)時減(jian)(jian)(jian)速(su)(su)電(dian)(dian)機(ji)(ji)的(de)類型很多，減(jian)(jian)(jian)速(su)(su)電(dian)(dian)機(ji)(ji)可按(an)傳動條件(jian)的(de)不同(tong)(tong)分為齒輪(lun)減(jian)(jian)(jian)速(su)(su)電(dian)(dian)機(ji)(ji)、蝸桿減(jian)(jian)(jian)速(su)(su)電(dian)(dian)機(ji)(ji)、蝸桿—齒輪(lun)減(jian)(jian)(jian)速(su)(su)電(dian)(dian)機(ji)(ji)和(he)行星齒輪(lun)減(jian)(jian)(jian)速(su)(su)電(dian)(dian)機(ji)(ji)；而(er)按(an)減(jian)(jian)(jian)速(su)(su)電(dian)(dian)機(ji)(ji)的(de)級數可分為單級減(jian)(jian)(jian)速(su)(su)電(dian)(dian)機(ji)(ji)、雙級減(jian)(jian)(jian)速(su)(su)電(dian)(dian)機(ji)(ji)和(he)多級減(jian)(jian)(jian)速(su)(su)電(dian)(dian)機(ji)(ji)；而(er)按(an)軸在空間的(de)相(xiang)對位置(zhi)，可分為臥式減(jian)(jian)(jian)速(su)(su)電(dian)(dian)機(ji)(ji)和(he)立式減(jian)(jian)(jian)速(su)(su)電(dian)(dian)機(ji)(ji)。

??直流減(jian)(jian)(jian)速電機(ji)的(de)(de)箱(xiang)體(ti)設計(ji)一般(ban)要(yao)考慮到減(jian)(jian)(jian)速電機(ji)箱(xiang)體(ti)的(de)(de)剛(gang)(gang)度(du)、密(mi)封、潤滑(hua)以及工藝性(xing)等(deng)因素。減(jian)(jian)(jian)速電機(ji)的(de)(de)箱(xiang)體(ti)必(bi)須要(yao)有(you)足夠(gou)的(de)(de)剛(gang)(gang)度(du)，不允許在工作過(guo)程中產(chan)生過(guo)大的(de)(de)變(bian)形而影(ying)響到傳動(dong)精(jing)度(du)。為(wei)了減(jian)(jian)(jian)速電機(ji)箱(xiang)體(ti)的(de)(de)剛(gang)(gang)度(du)，箱(xiang)體(ti)應有(you)足夠(gou)的(de)(de)壁(bi)厚(hou)，并在軸承座(zuo)附件加(jia)筋板。
