傳動滾筒是傳遞動力的重要部件，滾筒有光面、膠面。膠面形狀又可分成光面膠，人字膠及菱形膠，以適應不同工藝需求。

傳(chuan)動(dong)(dong)滾(gun)(gun)(gun)(gun)筒(tong)(tong)(tong)是(shi)(shi)帶(dai)式(shi)輸送機(ji)(ji)傳(chuan)動(dong)(dong)動(dong)(dong)力(li)的(de)主(zhu)要(yao)部件。作為單點(dian)(dian)驅(qu)動(dong)(dong)方式(shi)來講，可(ke)分(fen)成單滾(gun)(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)動(dong)(dong)及雙(shuang)滾(gun)(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)動(dong)(dong)。單滾(gun)(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)動(dong)(dong)多用(yong)(yong)于功率不(bu)太(tai)大(da)的(de)輸送機(ji)(ji)上，功率較大(da)的(de)輸送機(ji)(ji)可(ke)采(cai)用(yong)(yong)雙(shuang)滾(gun)(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)動(dong)(dong)，其特點(dian)(dian)是(shi)(shi)結構緊(jin)湊，還(huan)可(ke)增加(jia)圍包角以(yi)增加(jia)傳(chuan)動(dong)(dong)滾(gun)(gun)(gun)(gun)筒(tong)(tong)(tong)所能傳(chuan)遞(di)的(de)牽引力(li)。使用(yong)(yong)雙(shuang)滾(gun)(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)動(dong)(dong)時可(ke)以(yi)采(cai)用(yong)(yong)多電機(ji)(ji)分(fen)別傳(chuan)動(dong)(dong)，可(ke)以(yi)利用(yong)(yong)齒(chi)輪傳(chuan)動(dong)(dong)裝置使兩(liang)滾(gun)(gun)(gun)(gun)筒(tong)(tong)(tong)同速運轉。如(ru)雙(shuang)滾(gun)(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)動(dong)(dong)仍不(bu)需要(yao)牽引力(li)需要(yao)，可(ke)采(cai)用(yong)(yong)多點(dian)(dian)驅(qu)動(dong)(dong)方式(shi)。
