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)滾(gun)(gun)筒(tong)(tong)是帶式(shi)輸(shu)送機傳(chuan)動(dong)動(dong)力的主要(yao)部件。作為單點驅(qu)動(dong)方式(shi)來講，可分(fen)成(cheng)單滾(gun)(gun)筒(tong)(tong)傳(chuan)動(dong)及(ji)雙滾(gun)(gun)筒(tong)(tong)傳(chuan)動(dong)。單滾(gun)(gun)筒(tong)(tong)傳(chuan)動(dong)多(duo)用(yong)(yong)于功率不太大的輸(shu)送機上，功率較大的輸(shu)送機可采(cai)(cai)用(yong)(yong)雙滾(gun)(gun)筒(tong)(tong)傳(chuan)動(dong)，其(qi)特(te)點是結構緊(jin)湊，還可增加圍包角以(yi)增加傳(chuan)動(dong)滾(gun)(gun)筒(tong)(tong)所能傳(chuan)遞的牽引(yin)力。使(shi)(shi)用(yong)(yong)雙滾(gun)(gun)筒(tong)(tong)傳(chuan)動(dong)時可以(yi)采(cai)(cai)用(yong)(yong)多(duo)電機分(fen)別傳(chuan)動(dong)，可以(yi)利用(yong)(yong)齒輪(lun)傳(chuan)動(dong)裝置使(shi)(shi)兩滾(gun)(gun)筒(tong)(tong)同速(su)運轉。如雙滾(gun)(gun)筒(tong)(tong)傳(chuan)動(dong)仍不需要(yao)牽引(yin)力需要(yao)，可采(cai)(cai)用(yong)(yong)多(duo)點驅(qu)動(dong)方式(shi)。
