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)(gun)筒是帶式輸送(song)機(ji)傳(chuan)(chuan)(chuan)動(dong)動(dong)力的主要(yao)部(bu)件。作為單點驅動(dong)方式來(lai)講，可(ke)(ke)分成單滾(gun)(gun)(gun)筒傳(chuan)(chuan)(chuan)動(dong)及雙(shuang)滾(gun)(gun)(gun)筒傳(chuan)(chuan)(chuan)動(dong)。單滾(gun)(gun)(gun)筒傳(chuan)(chuan)(chuan)動(dong)多(duo)(duo)用(yong)于功率(lv)不(bu)太(tai)大(da)(da)的輸送(song)機(ji)上，功率(lv)較大(da)(da)的輸送(song)機(ji)可(ke)(ke)采用(yong)雙(shuang)滾(gun)(gun)(gun)筒傳(chuan)(chuan)(chuan)動(dong)，其特點是結(jie)構(gou)緊湊(cou)，還可(ke)(ke)增(zeng)加圍(wei)包(bao)角以增(zeng)加傳(chuan)(chuan)(chuan)動(dong)滾(gun)(gun)(gun)筒所(suo)能傳(chuan)(chuan)(chuan)遞的牽引(yin)(yin)力。使用(yong)雙(shuang)滾(gun)(gun)(gun)筒傳(chuan)(chuan)(chuan)動(dong)時可(ke)(ke)以采用(yong)多(duo)(duo)電機(ji)分別傳(chuan)(chuan)(chuan)動(dong)，可(ke)(ke)以利用(yong)齒(chi)輪傳(chuan)(chuan)(chuan)動(dong)裝置使兩滾(gun)(gun)(gun)筒同速運轉(zhuan)。如雙(shuang)滾(gun)(gun)(gun)筒傳(chuan)(chuan)(chuan)動(dong)仍不(bu)需要(yao)牽引(yin)(yin)力需要(yao)，可(ke)(ke)采用(yong)多(duo)(duo)點驅動(dong)方式。
