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)(dong)(dong)(dong)(dong)滾(gun)筒(tong)(tong)是(shi)帶式(shi)(shi)(shi)輸送(song)機(ji)(ji)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)(dong)力(li)的(de)(de)主要(yao)部件。作為單(dan)(dan)點驅動(dong)(dong)(dong)(dong)(dong)方(fang)式(shi)(shi)(shi)來講，可(ke)(ke)分成單(dan)(dan)滾(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)及(ji)雙(shuang)滾(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)。單(dan)(dan)滾(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)多(duo)用(yong)于功率不太大的(de)(de)輸送(song)機(ji)(ji)上，功率較大的(de)(de)輸送(song)機(ji)(ji)可(ke)(ke)采用(yong)雙(shuang)滾(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，其特點是(shi)結構緊湊，還可(ke)(ke)增(zeng)加(jia)(jia)圍包角以(yi)增(zeng)加(jia)(jia)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)滾(gun)筒(tong)(tong)所能(neng)傳(chuan)(chuan)(chuan)遞的(de)(de)牽(qian)引力(li)。使用(yong)雙(shuang)滾(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)時可(ke)(ke)以(yi)采用(yong)多(duo)電(dian)機(ji)(ji)分別傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，可(ke)(ke)以(yi)利用(yong)齒輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)裝置使兩滾(gun)筒(tong)(tong)同速運轉。如雙(shuang)滾(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)仍不需要(yao)牽(qian)引力(li)需要(yao)，可(ke)(ke)采用(yong)多(duo)點驅動(dong)(dong)(dong)(dong)(dong)方(fang)式(shi)(shi)(shi)。
