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)動(dong)(dong)滾筒(tong)(tong)(tong)是(shi)帶式(shi)輸送機傳(chuan)(chuan)動(dong)(dong)動(dong)(dong)力(li)(li)的主要部(bu)件。作為單(dan)(dan)點(dian)驅動(dong)(dong)方式(shi)來(lai)講(jiang)，可分成單(dan)(dan)滾筒(tong)(tong)(tong)傳(chuan)(chuan)動(dong)(dong)及雙(shuang)滾筒(tong)(tong)(tong)傳(chuan)(chuan)動(dong)(dong)。單(dan)(dan)滾筒(tong)(tong)(tong)傳(chuan)(chuan)動(dong)(dong)多用(yong)于功率不(bu)(bu)太大(da)的輸送機上(shang)，功率較大(da)的輸送機可采(cai)用(yong)雙(shuang)滾筒(tong)(tong)(tong)傳(chuan)(chuan)動(dong)(dong)，其特點(dian)是(shi)結構緊湊(cou)，還可增加(jia)圍包(bao)角以(yi)增加(jia)傳(chuan)(chuan)動(dong)(dong)滾筒(tong)(tong)(tong)所能傳(chuan)(chuan)遞的牽引力(li)(li)。使(shi)用(yong)雙(shuang)滾筒(tong)(tong)(tong)傳(chuan)(chuan)動(dong)(dong)時可以(yi)采(cai)用(yong)多電機分別傳(chuan)(chuan)動(dong)(dong)，可以(yi)利用(yong)齒輪傳(chuan)(chuan)動(dong)(dong)裝置使(shi)兩滾筒(tong)(tong)(tong)同速運轉。如雙(shuang)滾筒(tong)(tong)(tong)傳(chuan)(chuan)動(dong)(dong)仍不(bu)(bu)需要牽引力(li)(li)需要，可采(cai)用(yong)多點(dian)驅動(dong)(dong)方式(shi)。
