行(xing)星(xing)減速(su)機(ji)(ji)操作需(xu)注意(yi)什么？行(xing)星(xing)減速(su)機(ji)(ji)同心(xin)度(du)有(you)誤差將(jiang)會造(zao)成很(hen)大損(sun)失，當(dang)驅(qu)動(dong)(dong)電(dian)機(ji)(ji)和行(xing)星(xing)減速(su)機(ji)(ji)間裝配同心(xin)度(du)保證得(de)較好時，驅(qu)動(dong)(dong)電(dian)機(ji)(ji)輸(shu)(shu)出(chu)軸所承受(shou)的僅僅是(shi)轉動(dong)(dong)力（扭矩），運轉時也會很(hen)平(ping)順，沒有(you)脈動(dong)(dong)感(gan)。而(er)在不同心(xin)時，驅(qu)動(dong)(dong)電(dian)機(ji)(ji)輸(shu)(shu)出(chu)軸還(huan)要(yao)承受(shou)來(lai)自(zi)于行(xing)星(xing)減速(su)機(ji)(ji)輸(shu)(shu)入端的徑(jing)向力（彎矩）。

這個徑(jing)(jing)向(xiang)力(li)(li)(li)的(de)(de)(de)(de)作用將會使(shi)驅(qu)(qu)動(dong)電(dian)機輸(shu)(shu)(shu)(shu)出(chu)(chu)(chu)軸(zhou)(zhou)被迫彎曲，而(er)且彎曲的(de)(de)(de)(de)方向(xiang)會隨著輸(shu)(shu)(shu)(shu)出(chu)(chu)(chu)軸(zhou)(zhou)轉(zhuan)動(dong)不斷(duan)(duan)(duan)變化。如(ru)果同(tong)(tong)(tong)心(xin)度(du)的(de)(de)(de)(de)誤差較(jiao)大時，該徑(jing)(jing)向(xiang)力(li)(li)(li)使(shi)電(dian)機輸(shu)(shu)(shu)(shu)出(chu)(chu)(chu)軸(zhou)(zhou)局部溫度(du)升高，其金屬結構(gou)不斷(duan)(duan)(duan)被破壞，終(zhong)將導(dao)致驅(qu)(qu)動(dong)電(dian)機輸(shu)(shu)(shu)(shu)出(chu)(chu)(chu)軸(zhou)(zhou)因局部疲(pi)勞而(er)折(zhe)斷(duan)(duan)(duan)。兩者同(tong)(tong)(tong)心(xin)度(du)的(de)(de)(de)(de)誤差越大時，驅(qu)(qu)動(dong)電(dian)機輸(shu)(shu)(shu)(shu)出(chu)(chu)(chu)軸(zhou)(zhou)折(zhe)斷(duan)(duan)(duan)的(de)(de)(de)(de)時間(jian)越短。在驅(qu)(qu)動(dong)電(dian)機輸(shu)(shu)(shu)(shu)出(chu)(chu)(chu)軸(zhou)(zhou)折(zhe)斷(duan)(duan)(duan)的(de)(de)(de)(de)同(tong)(tong)(tong)時，減(jian)(jian)行星速(su)機輸(shu)(shu)(shu)(shu)入(ru)端同(tong)(tong)(tong)樣也會承(cheng)(cheng)受來自于(yu)驅(qu)(qu)動(dong)電(dian)機輸(shu)(shu)(shu)(shu)出(chu)(chu)(chu)軸(zhou)(zhou)方面(mian)的(de)(de)(de)(de)徑(jing)(jing)向(xiang)力(li)(li)(li)，如(ru)果這個徑(jing)(jing)向(xiang)力(li)(li)(li)超出(chu)(chu)(chu)減(jian)(jian)速(su)機輸(shu)(shu)(shu)(shu)入(ru)端所(suo)能承(cheng)(cheng)受的(de)(de)(de)(de)大徑(jing)(jing)向(xiang)負荷(he)的(de)(de)(de)(de)話(hua)，其結果也將導(dao)致減(jian)(jian)速(su)機輸(shu)(shu)(shu)(shu)入(ru)端產生變形(xing)甚(shen)到斷(duan)(duan)(duan)裂(lie)或(huo)輸(shu)(shu)(shu)(shu)入(ru)端支撐軸(zhou)(zhou)承(cheng)(cheng)損壞。因此，在裝配時保證(zheng)同(tong)(tong)(tong)心(xin)度(du)到關重(zhong)要！從裝配工藝上分析，如(ru)果驅(qu)(qu)動(dong)電(dian)機軸(zhou)(zhou)和減(jian)(jian)速(su)機輸(shu)(shu)(shu)(shu)入(ru)端同(tong)(tong)(tong)心(xin)，那么驅(qu)(qu)動(dong)電(dian)機軸(zhou)(zhou)面(mian)和減(jian)(jian)速(su)機輸(shu)(shu)(shu)(shu)入(ru)端孔面(mian)間(jian)就會很(hen)吻合，它們(men)的(de)(de)(de)(de)接觸面(mian)緊緊相貼，沒有(you)徑(jing)(jing)向(xiang)力(li)(li)(li)和變形(xing)空間(jian)。而(er)裝配時如(ru)果不同(tong)(tong)(tong)心(xin)，那么接觸面(mian)之間(jian)就會不吻合或(huo)有(you)間(jian)隙(xi)，就有(you)徑(jing)(jing)向(xiang)力(li)(li)(li)并給變形(xing)提(ti)供了空間(jian)。

同(tong)樣，行星減速(su)(su)機(ji)的(de)輸(shu)出(chu)(chu)(chu)軸也(ye)有(you)折(zhe)斷(duan)或(huo)彎曲現象發生，其(qi)原因與(yu)驅動電(dian)機(ji)的(de)斷(duan)軸原因相(xiang)同(tong)。但減速(su)(su)機(ji)的(de)出(chu)(chu)(chu)力(li)是驅動電(dian)機(ji)出(chu)(chu)(chu)力(li)和減速(su)(su)比之積(ji)，相(xiang)對于電(dian)機(ji)來(lai)講出(chu)(chu)(chu)力(li)更大，故減速(su)(su)機(ji)輸(shu)出(chu)(chu)(chu)軸更易被折(zhe)斷(duan)。因此，用戶在使用減速(su)(su)機(ji)時，對其(qi)輸(shu)出(chu)(chu)(chu)端裝配時同(tong)心度的(de)保證更應十分注意(yi)！
