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)(chuan)動(dong)滾(gun)(gun)筒(tong)(tong)是(shi)帶式輸送機傳(chuan)(chuan)(chuan)動(dong)動(dong)力(li)(li)的主(zhu)要部件。作為單(dan)點(dian)驅動(dong)方(fang)式來講(jiang)，可(ke)分成單(dan)滾(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)及(ji)雙(shuang)滾(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)。單(dan)滾(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)多(duo)用于功率(lv)不太大的輸送機上，功率(lv)較大的輸送機可(ke)采(cai)(cai)用雙(shuang)滾(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)，其特點(dian)是(shi)結(jie)構(gou)緊湊(cou)，還可(ke)增(zeng)加(jia)圍包角以增(zeng)加(jia)傳(chuan)(chuan)(chuan)動(dong)滾(gun)(gun)筒(tong)(tong)所能(neng)傳(chuan)(chuan)(chuan)遞的牽引(yin)力(li)(li)。使用雙(shuang)滾(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)時(shi)可(ke)以采(cai)(cai)用多(duo)電(dian)機分別傳(chuan)(chuan)(chuan)動(dong)，可(ke)以利(li)用齒輪傳(chuan)(chuan)(chuan)動(dong)裝置(zhi)使兩(liang)滾(gun)(gun)筒(tong)(tong)同速運(yun)轉。如雙(shuang)滾(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)仍不需(xu)要牽引(yin)力(li)(li)需(xu)要，可(ke)采(cai)(cai)用多(duo)點(dian)驅動(dong)方(fang)式。
