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)(chuan)動(dong)(dong)(dong)滾(gun)(gun)(gun)筒(tong)是帶式(shi)(shi)輸送機(ji)傳(chuan)(chuan)動(dong)(dong)(dong)動(dong)(dong)(dong)力(li)的主要(yao)(yao)部件。作為單點(dian)驅(qu)動(dong)(dong)(dong)方(fang)式(shi)(shi)來講，可(ke)分(fen)成(cheng)單滾(gun)(gun)(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)(dong)及(ji)雙滾(gun)(gun)(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)(dong)。單滾(gun)(gun)(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)(dong)多用于功(gong)率不太大的輸送機(ji)上，功(gong)率較大的輸送機(ji)可(ke)采用雙滾(gun)(gun)(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)(dong)，其特點(dian)是結(jie)構緊(jin)湊(cou)，還可(ke)增(zeng)加(jia)圍包(bao)角以增(zeng)加(jia)傳(chuan)(chuan)動(dong)(dong)(dong)滾(gun)(gun)(gun)筒(tong)所能(neng)傳(chuan)(chuan)遞(di)的牽(qian)引力(li)。使用雙滾(gun)(gun)(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)(dong)時(shi)可(ke)以采用多電機(ji)分(fen)別傳(chuan)(chuan)動(dong)(dong)(dong)，可(ke)以利(li)用齒輪傳(chuan)(chuan)動(dong)(dong)(dong)裝置使兩滾(gun)(gun)(gun)筒(tong)同速運轉。如雙滾(gun)(gun)(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)(dong)仍(reng)不需(xu)要(yao)(yao)牽(qian)引力(li)需(xu)要(yao)(yao)，可(ke)采用多點(dian)驅(qu)動(dong)(dong)(dong)方(fang)式(shi)(shi)。
