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。

傳動(dong)(dong)(dong)滾筒(tong)(tong)是帶(dai)式(shi)輸送機傳動(dong)(dong)(dong)動(dong)(dong)(dong)力(li)的(de)主要(yao)部件(jian)。作為單點(dian)驅(qu)動(dong)(dong)(dong)方式(shi)來講(jiang)，可(ke)分成單滾筒(tong)(tong)傳動(dong)(dong)(dong)及(ji)雙滾筒(tong)(tong)傳動(dong)(dong)(dong)。單滾筒(tong)(tong)傳動(dong)(dong)(dong)多(duo)用(yong)(yong)于功率不(bu)太大的(de)輸送機上，功率較大的(de)輸送機可(ke)采用(yong)(yong)雙滾筒(tong)(tong)傳動(dong)(dong)(dong)，其(qi)特點(dian)是結構緊湊，還(huan)可(ke)增加(jia)圍包角以增加(jia)傳動(dong)(dong)(dong)滾筒(tong)(tong)所能傳遞的(de)牽引(yin)力(li)。使用(yong)(yong)雙滾筒(tong)(tong)傳動(dong)(dong)(dong)時可(ke)以采用(yong)(yong)多(duo)電機分別(bie)傳動(dong)(dong)(dong)，可(ke)以利用(yong)(yong)齒(chi)輪傳動(dong)(dong)(dong)裝(zhuang)置使兩滾筒(tong)(tong)同速運(yun)轉。如雙滾筒(tong)(tong)傳動(dong)(dong)(dong)仍不(bu)需(xu)要(yao)牽引(yin)力(li)需(xu)要(yao)，可(ke)采用(yong)(yong)多(duo)點(dian)驅(qu)動(dong)(dong)(dong)方式(shi)。
