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)(chuan)動(dong)(dong)(dong)滾(gun)(gun)筒(tong)是(shi)帶式(shi)輸(shu)送機(ji)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)動(dong)(dong)(dong)力的主要(yao)部(bu)件。作為單點(dian)驅動(dong)(dong)(dong)方(fang)式(shi)來講，可(ke)(ke)分(fen)成單滾(gun)(gun)筒(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)及雙滾(gun)(gun)筒(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)。單滾(gun)(gun)筒(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)多用于功(gong)率不太大的輸(shu)送機(ji)上，功(gong)率較大的輸(shu)送機(ji)可(ke)(ke)采(cai)用雙滾(gun)(gun)筒(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)，其特點(dian)是(shi)結構緊(jin)湊，還(huan)可(ke)(ke)增加圍包角以增加傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)滾(gun)(gun)筒(tong)所能傳(chuan)(chuan)(chuan)(chuan)遞的牽引力。使(shi)用雙滾(gun)(gun)筒(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)時可(ke)(ke)以采(cai)用多電機(ji)分(fen)別傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)，可(ke)(ke)以利用齒(chi)輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)裝(zhuang)置使(shi)兩(liang)滾(gun)(gun)筒(tong)同速運(yun)轉。如雙滾(gun)(gun)筒(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)仍(reng)不需要(yao)牽引力需要(yao)，可(ke)(ke)采(cai)用多點(dian)驅動(dong)(dong)(dong)方(fang)式(shi)。
