反擊式碎石(shi)機行星(xing)齒輪(lun)(lun)傳動(dong)(dong)比(bi)大，并(bing)可實(shi)現運動(dong)(dong)的(de)(de)(de)合成與分解，有級變速與無級變速。只要根(gen)據(ju)碎石(shi)機的(de)(de)(de)特性，適(shi)當選擇傳動(dong)(dong)類型及各齒輪(lun)(lun)的(de)(de)(de)齒輪(lun)(lun)，使可利(li)用少數(shu)幾個齒輪(lun)(lun)而(er)獲得很(hen)大的(de)(de)(de)傳動(dong)(dong)比(bi)。

在(zai)不作為動(dong)(dong)(dong)(dong)力傳(chuan)(chuan)動(dong)(dong)(dong)(dong)而主要是用以實現(xian)(xian)某一運動(dong)(dong)(dong)(dong)時，其傳(chuan)(chuan)動(dong)(dong)(dong)(dong)比可(ke)達十的六次方，行星齒輪傳(chuan)(chuan)動(dong)(dong)(dong)(dong)由于(yu)它(ta)的是哪個基(ji)本(ben)購(gou)機都可(ke)以轉動(dong)(dong)(dong)(dong)，故可(ke)實現(xian)(xian)運動(dong)(dong)(dong)(dong)的合(he)成與(yu)分解，以及實現(xian)(xian)有級和無級變速(su)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)等復雜(za)的運動(dong)(dong)(dong)(dong)。
