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)滾筒(tong)(tong)(tong)是帶式(shi)輸送(song)機(ji)傳(chuan)(chuan)(chuan)動(dong)(dong)動(dong)(dong)力(li)的主要(yao)部(bu)件(jian)。作為單點驅動(dong)(dong)方式(shi)來(lai)講，可(ke)分成(cheng)單滾筒(tong)(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)(dong)及(ji)雙滾筒(tong)(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)(dong)。單滾筒(tong)(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)(dong)多(duo)(duo)用于功率不太大的輸送(song)機(ji)上，功率較大的輸送(song)機(ji)可(ke)采(cai)用雙滾筒(tong)(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)(dong)，其特點是結(jie)構緊湊(cou)，還可(ke)增加圍(wei)包角以增加傳(chuan)(chuan)(chuan)動(dong)(dong)滾筒(tong)(tong)(tong)所能傳(chuan)(chuan)(chuan)遞的牽引(yin)力(li)。使(shi)用雙滾筒(tong)(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)(dong)時可(ke)以采(cai)用多(duo)(duo)電機(ji)分別傳(chuan)(chuan)(chuan)動(dong)(dong)，可(ke)以利用齒(chi)輪傳(chuan)(chuan)(chuan)動(dong)(dong)裝置使(shi)兩滾筒(tong)(tong)(tong)同速運轉(zhuan)。如雙滾筒(tong)(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)(dong)仍不需(xu)要(yao)牽引(yin)力(li)需(xu)要(yao)，可(ke)采(cai)用多(duo)(duo)點驅動(dong)(dong)方式(shi)。
