拖(tuo)動(dong)(dong)轉子的傳動(dong)(dong)方式有(you)圈帶拖(tuo)動(dong)(dong)，聯軸節拖(tuo)動(dong)(dong)和(he)自(zi)驅動(dong)(dong)。

　　1,圈帶(dai)拖動(dong)(dong)----是利用橡膠(jiao)環形(xing)帶(dai)或絲織環形(xing)帶(dai)，由電機皮帶(dai)輪拖動(dong)(dong)轉(zhuan)子，因此圈帶(dai)拖動(dong)(dong)要求(qiu)轉(zhuan)子表面必須有光滑的圓柱表面，圈帶(dai)拖動(dong)(dong)的優點是不影響(xiang)轉(zhuan)子的不平(ping)衡量，平(ping)衡精度高。

　　2.聯(lian)(lian)軸(zhou)節拖動----是利用萬向節將平(ping)衡機主軸(zhou)與轉子(zi)相(xiang)聯(lian)(lian)接。聯(lian)(lian)軸(zhou)節拖動的(de)特(te)點是 適合外(wai)表不規則的(de)轉子(zi)，可(ke)以傳(chuan)遞較大的(de)扭矩，適合拖動風機等風阻較大的(de)轉子(zi)，聯(lian)(lian)軸(zhou)節拖動的(de)缺點是聯(lian)(lian)軸(zhou)節本身的(de)不平(ping)衡量會對轉子(zi)產生影響（因此(ci)(ci)聯(lian)(lian)軸(zhou)節在使(shi) 用前要對其進(jin)(jin)行平(ping)衡），也會引進(jin)(jin)干擾影響平(ping)衡的(de)精度，此(ci)(ci)外(wai)還要做大量的(de)連接 盤以適應(ying)不同型號的(de)轉子(zi)。

　　3,自驅(qu)動(dong)(dong)----是(shi)利用(yong)轉(zhuan)子自身的動(dong)(dong)力(li)旋(xuan)轉(zhuan)。自驅(qu)動(dong)(dong)是(shi)對平衡精度影響最小的拖動(dong)(dong)方式(shi)，平衡精度可(ke)達最高(gao)，但(dan)只有結構允許的特殊轉(zhuan)子才(cai)能使用(yong)這種拖動(dong)(dong)方式(shi)。

　　平(ping)(ping)衡(heng)(heng)機(ji)(ji)拖(tuo)(tuo)動(dong)(dong)(dong)(dong)轉(zhuan)(zhuan)(zhuan)子(zi)的(de)(de)傳(chuan)動(dong)(dong)(dong)(dong)方式(shi)有圈(quan)(quan)帶(dai)(dai)(dai)拖(tuo)(tuo)動(dong)(dong)(dong)(dong)，聯(lian)(lian)軸(zhou)(zhou)節拖(tuo)(tuo)動(dong)(dong)(dong)(dong)和自驅動(dong)(dong)(dong)(dong)。圈(quan)(quan)帶(dai)(dai)(dai)拖(tuo)(tuo)動(dong)(dong)(dong)(dong)是(shi)利(li)(li)用橡(xiang)膠環(huan)形帶(dai)(dai)(dai)或絲(si)織環(huan)形帶(dai)(dai)(dai)，由電機(ji)(ji)皮帶(dai)(dai)(dai)輪拖(tuo)(tuo)動(dong)(dong)(dong)(dong)轉(zhuan)(zhuan)(zhuan)子(zi)，因此(ci)圈(quan)(quan)帶(dai)(dai)(dai)拖(tuo)(tuo)動(dong)(dong)(dong)(dong)要(yao)求(qiu)轉(zhuan)(zhuan)(zhuan)子(zi)表面必須有光滑的(de)(de)圓(yuan)柱(zhu)表面，圈(quan)(quan)帶(dai)(dai)(dai)拖(tuo)(tuo)動(dong)(dong)(dong)(dong)的(de)(de)優點是(shi)不(bu)影響(xiang)(xiang)轉(zhuan)(zhuan)(zhuan)子(zi)的(de)(de)不(bu)平(ping)(ping)衡(heng)(heng)量(liang)，平(ping)(ping)衡(heng)(heng)精度(du)高。聯(lian)(lian)軸(zhou)(zhou)節拖(tuo)(tuo)動(dong)(dong)(dong)(dong)是(shi)利(li)(li)用萬向節將平(ping)(ping)衡(heng)(heng)機(ji)(ji)主軸(zhou)(zhou)與轉(zhuan)(zhuan)(zhuan)子(zi)相聯(lian)(lian)接(jie)。聯(lian)(lian)軸(zhou)(zhou)節拖(tuo)(tuo)動(dong)(dong)(dong)(dong)的(de)(de)特點是(shi)適合(he)外表不(bu)規則的(de)(de)轉(zhuan)(zhuan)(zhuan)子(zi)，可(ke)以傳(chuan)遞較大的(de)(de)扭矩，適合(he)拖(tuo)(tuo)動(dong)(dong)(dong)(dong)風機(ji)(ji)等風阻較大的(de)(de)轉(zhuan)(zhuan)(zhuan)子(zi)，聯(lian)(lian)軸(zhou)(zhou)節拖(tuo)(tuo)動(dong)(dong)(dong)(dong)的(de)(de)缺(que)點是(shi)聯(lian)(lian)軸(zhou)(zhou)節本身的(de)(de)不(bu)平(ping)(ping)衡(heng)(heng)量(liang)會(hui)對(dui)轉(zhuan)(zhuan)(zhuan)子(zi)產生影響(xiang)(xiang)（因此(ci)聯(lian)(lian)軸(zhou)(zhou)節在使用前要(yao)對(dui)其進行平(ping)(ping)衡(heng)(heng)），也(ye)會(hui)引進干擾影響(xiang)(xiang)平(ping)(ping)衡(heng)(heng)的(de)(de)精度(du)，此(ci)外還要(yao)做(zuo)大量(liang)的(de)(de)連接(jie)盤以適應不(bu)同型號(hao)的(de)(de)轉(zhuan)(zhuan)(zhuan)子(zi)。自驅動(dong)(dong)(dong)(dong)是(shi)利(li)(li)用轉(zhuan)(zhuan)(zhuan)子(zi)自身的(de)(de)動(dong)(dong)(dong)(dong)力旋(xuan)轉(zhuan)(zhuan)(zhuan)。自驅動(dong)(dong)(dong)(dong)是(shi)對(dui)平(ping)(ping)衡(heng)(heng)精度(du)影響(xiang)(xiang)最(zui)小的(de)(de)拖(tuo)(tuo)動(dong)(dong)(dong)(dong)方式(shi)，平(ping)(ping)衡(heng)(heng)精度(du)可(ke)達(da)最(zui)高，但只有結構允許(xu)的(de)(de)特殊轉(zhuan)(zhuan)(zhuan)子(zi)才能使用這種拖(tuo)(tuo)動(dong)(dong)(dong)(dong)方式(shi)。
