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)動(dong)(dong)滾筒(tong)(tong)(tong)(tong)(tong)是(shi)(shi)帶式(shi)輸(shu)送機(ji)(ji)(ji)傳(chuan)動(dong)(dong)動(dong)(dong)力(li)的(de)主要(yao)部件。作為單(dan)點(dian)驅動(dong)(dong)方(fang)式(shi)來(lai)講，可(ke)分成單(dan)滾筒(tong)(tong)(tong)(tong)(tong)傳(chuan)動(dong)(dong)及(ji)雙滾筒(tong)(tong)(tong)(tong)(tong)傳(chuan)動(dong)(dong)。單(dan)滾筒(tong)(tong)(tong)(tong)(tong)傳(chuan)動(dong)(dong)多用(yong)(yong)于功(gong)率不太(tai)大(da)的(de)輸(shu)送機(ji)(ji)(ji)上，功(gong)率較大(da)的(de)輸(shu)送機(ji)(ji)(ji)可(ke)采(cai)用(yong)(yong)雙滾筒(tong)(tong)(tong)(tong)(tong)傳(chuan)動(dong)(dong)，其特點(dian)是(shi)(shi)結構緊湊(cou)，還可(ke)增加圍包角以增加傳(chuan)動(dong)(dong)滾筒(tong)(tong)(tong)(tong)(tong)所能傳(chuan)遞的(de)牽(qian)引力(li)。使(shi)用(yong)(yong)雙滾筒(tong)(tong)(tong)(tong)(tong)傳(chuan)動(dong)(dong)時可(ke)以采(cai)用(yong)(yong)多電機(ji)(ji)(ji)分別傳(chuan)動(dong)(dong)，可(ke)以利用(yong)(yong)齒輪(lun)傳(chuan)動(dong)(dong)裝置使(shi)兩滾筒(tong)(tong)(tong)(tong)(tong)同速運轉。如雙滾筒(tong)(tong)(tong)(tong)(tong)傳(chuan)動(dong)(dong)仍不需要(yao)牽(qian)引力(li)需要(yao)，可(ke)采(cai)用(yong)(yong)多點(dian)驅動(dong)(dong)方(fang)式(shi)。
