行星減速機體積(ji)較小,傳動效(xiao)率高(gao)。
行星(xing)(xing)(xing)(xing)減(jian)(jian)(jian)(jian)速(su)機(ji)裝配時(shi)(shi)(shi)同心度的(de)(de)好時(shi)(shi)(shi),行星(xing)(xing)(xing)(xing)減(jian)(jian)(jian)(jian)速(su)機(ji)輸(shu)出(chu)軸(zhou)承(cheng)受(shou)的(de)(de)僅僅是旋轉(zhuan)力(li)(li),運轉(zhuan)時(shi)(shi)(shi)也會很(hen)輕松。然而(er)行星(xing)(xing)(xing)(xing)減(jian)(jian)(jian)(jian)速(su)機(ji)與(yu)減(jian)(jian)(jian)(jian)速(su)機(ji)連(lian)接不同心時(shi)(shi)(shi),輸(shu)出(chu)軸(zhou)要承(cheng)受(shou)來自于減(jian)(jian)(jian)(jian)速(su)機(ji)輸(shu)入端(duan)的(de)(de)徑向(xiang)(xiang)(xiang)(xiang)力(li)(li),這(zhe)個徑向(xiang)(xiang)(xiang)(xiang)力(li)(li)長期作(zuo)用將會使電機(ji)輸(shu)出(chu)軸(zhou)被(bei)迫(po)彎曲,而(er)且行星(xing)(xing)(xing)(xing)減(jian)(jian)(jian)(jian)速(su)機(ji)軸(zhou)彎曲的(de)(de)方向(xiang)(xiang)(xiang)(xiang)隨著輸(shu)出(chu)軸(zhou)轉(zhuan)動不斷(duan)變化。行星(xing)(xing)(xing)(xing)減(jian)(jian)(jian)(jian)速(su)機(ji)輸(shu)出(chu)軸(zhou)每轉(zhuan)動一(yi)周,橫向(xiang)(xiang)(xiang)(xiang)力(li)(li)的(de)(de)方向(xiang)(xiang)(xiang)(xiang)變化360度。如果同心度的(de)(de)誤(wu)差較(jiao)大(da)時(shi)(shi)(shi),該徑向(xiang)(xiang)(xiang)(xiang)力(li)(li)使電機(ji)輸(shu)出(chu)軸(zhou)溫度升(sheng),其金屬(shu)結構不斷(duan)被(bei)破(po)壞(huai),后該徑向(xiang)(xiang)(xiang)(xiang)力(li)(li)將會超出(chu)行星(xing)(xing)(xing)(xing)減(jian)(jian)(jian)(jian)速(su)機(ji)輸(shu)出(chu)軸(zhou)所(suo)能(neng)承(cheng)受(shou)的(de)(de)徑向(xiang)(xiang)(xiang)(xiang)力(li)(li),后導致行星(xing)(xing)(xing)(xing)減(jian)(jian)(jian)(jian)速(su)機(ji)輸(shu)出(chu)軸(zhou)折斷(duan)。
? 行星(xing)減(jian)速(su)機(ji)同(tong)心(xin)(xin)度的(de)(de)誤差越大時(shi),傳動電(dian)機(ji)輸出(chu)軸折斷的(de)(de)時(shi)間(jian)越短,所以在傳動電(dian)機(ji)輸出(chu)軸折斷的(de)(de)同(tong)時(shi),行星(xing)減(jian)速(su)機(ji)輸入(ru)端同(tong)樣也(ye)會(hui)承受來自(zi)于電(dian)機(ji)方面(mian)的(de)(de)徑向力,因(yin)此,在裝配時(shi)同(tong)心(xin)(xin)度很(hen)重要。
