行星減速機的傳動結構(gou)為目前齒輪減速機效率最(zui)高(gao)的組合，行星減速機基本(ben)傳動結構(gou)如下：

A、太陽齒輪(lun) sun gear

B、行星(xing)齒輪（組合(he)于行星(xing)架） planetary gear

C、內齒(chi)輪環 internal gearring

C、連接齒輪 using connected section`gear

E、行(xing)星架(jia) planetary carrier

F、出(chu)力軸 output shaft

驅動(dong)(dong)源以(yi)直結或連接(jie)方式啟動(dong)(dong)太陽齒(chi)(chi)(chi)輪，太陽齒(chi)(chi)(chi)輪將組合于行(xing)星(xing)(xing)(xing)架上的行(xing)星(xing)(xing)(xing)齒(chi)(chi)(chi)輪帶動(dong)(dong)運(yun)轉(zhuan)。整組行(xing)星(xing)(xing)(xing)齒(chi)(chi)(chi)輪系統沿著(zhu)外齒(chi)(chi)(chi)輪環自動(dong)(dong)繞行(xing)轉(zhuan)動(dong)(dong)，行(xing)星(xing)(xing)(xing)架連結出力軸輸出達到減(jian)速(su)目的。更高減(jian)速(su)比則借由(you)多組階段齒(chi)(chi)(chi)輪與行(xing)星(xing)(xing)(xing)齒(chi)(chi)(chi)輪倍增累(lei)計而成。

行(xing)星(xing)(xing)減速機由一(yi)(yi)個內(nei)(nei)齒環(huan)(A)緊密結合于(yu)(yu)齒箱(xiang)殼體上，環(huan)齒中心有一(yi)(yi)個自(zi)外部動(dong)力(li)(li)所驅動(dong)之(zhi)太陽齒輪(lun)(B)介于(yu)(yu)兩者之(zhi)間(jian)有一(yi)(yi)組由三(san)顆齒輪(lun)等分組合于(yu)(yu)托盤(pan)上之(zhi)行(xing)星(xing)(xing)齒輪(lun)組(C)該組行(xing)星(xing)(xing)齒輪(lun)依(yi)靠著(zhu)出(chu)力(li)(li)軸、內(nei)(nei)齒環(huan)及太陽齒支撐(cheng)浮游于(yu)(yu)期間(jian)；當(dang)入(ru)力(li)(li)側(ce)動(dong)力(li)(li)驅動(dong)太陽齒時，可帶(dai)(dai)動(dong)行(xing)星(xing)(xing)齒輪(lun)自(zi)轉，并依(yi)循著(zhu)內(nei)(nei)齒環(huan)之(zhi)軌跡沿著(zhu)中心公轉，行(xing)星(xing)(xing)之(zhi)旋轉帶(dai)(dai)動(dong)連結于(yu)(yu)托盤(pan)之(zhi)出(chu)力(li)(li)軸輸出(chu)動(dong)力(li)(li)。
