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。

傳動(dong)滾筒(tong)(tong)是帶(dai)式輸(shu)送(song)(song)機(ji)傳動(dong)動(dong)力的主要部件。作為(wei)單(dan)點(dian)(dian)驅動(dong)方式來講，可(ke)(ke)(ke)分(fen)成(cheng)單(dan)滾筒(tong)(tong)傳動(dong)及雙(shuang)滾筒(tong)(tong)傳動(dong)。單(dan)滾筒(tong)(tong)傳動(dong)多(duo)用(yong)(yong)于功(gong)率不(bu)太大的輸(shu)送(song)(song)機(ji)上，功(gong)率較大的輸(shu)送(song)(song)機(ji)可(ke)(ke)(ke)采(cai)用(yong)(yong)雙(shuang)滾筒(tong)(tong)傳動(dong)，其特點(dian)(dian)是結構(gou)緊湊(cou)，還可(ke)(ke)(ke)增加圍(wei)包角以(yi)(yi)增加傳動(dong)滾筒(tong)(tong)所能傳遞的牽引(yin)力。使用(yong)(yong)雙(shuang)滾筒(tong)(tong)傳動(dong)時可(ke)(ke)(ke)以(yi)(yi)采(cai)用(yong)(yong)多(duo)電機(ji)分(fen)別傳動(dong)，可(ke)(ke)(ke)以(yi)(yi)利用(yong)(yong)齒(chi)輪傳動(dong)裝置使兩滾筒(tong)(tong)同速運(yun)轉(zhuan)。如雙(shuang)滾筒(tong)(tong)傳動(dong)仍不(bu)需要牽引(yin)力需要，可(ke)(ke)(ke)采(cai)用(yong)(yong)多(duo)點(dian)(dian)驅動(dong)方式。
