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)滾筒(tong)(tong)是帶式(shi)(shi)輸(shu)送機(ji)傳(chuan)(chuan)(chuan)動(dong)動(dong)力(li)的(de)(de)主要部件。作為單點驅動(dong)方式(shi)(shi)來講(jiang)，可(ke)(ke)分(fen)(fen)成單滾筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)及雙(shuang)(shuang)滾筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)。單滾筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)多用(yong)(yong)于功(gong)率不太大(da)的(de)(de)輸(shu)送機(ji)上(shang)，功(gong)率較大(da)的(de)(de)輸(shu)送機(ji)可(ke)(ke)采(cai)(cai)用(yong)(yong)雙(shuang)(shuang)滾筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)，其特點是結構緊(jin)湊，還可(ke)(ke)增(zeng)(zeng)加(jia)圍包角(jiao)以(yi)增(zeng)(zeng)加(jia)傳(chuan)(chuan)(chuan)動(dong)滾筒(tong)(tong)所能傳(chuan)(chuan)(chuan)遞的(de)(de)牽引力(li)。使用(yong)(yong)雙(shuang)(shuang)滾筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)時可(ke)(ke)以(yi)采(cai)(cai)用(yong)(yong)多電機(ji)分(fen)(fen)別傳(chuan)(chuan)(chuan)動(dong)，可(ke)(ke)以(yi)利用(yong)(yong)齒輪傳(chuan)(chuan)(chuan)動(dong)裝置使兩(liang)滾筒(tong)(tong)同速運(yun)轉(zhuan)。如雙(shuang)(shuang)滾筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)仍(reng)不需(xu)要牽引力(li)需(xu)要，可(ke)(ke)采(cai)(cai)用(yong)(yong)多點驅動(dong)方式(shi)(shi)。
