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)(dong)(dong)滾(gun)筒(tong)(tong)(tong)(tong)是(shi)帶式輸送(song)機(ji)傳(chuan)動(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)力的主要(yao)(yao)部件。作為單點(dian)(dian)驅動(dong)(dong)(dong)(dong)方式來(lai)講，可(ke)(ke)分成單滾(gun)筒(tong)(tong)(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)及雙滾(gun)筒(tong)(tong)(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)。單滾(gun)筒(tong)(tong)(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)多(duo)用于(yu)功(gong)(gong)率不太(tai)大的輸送(song)機(ji)上，功(gong)(gong)率較大的輸送(song)機(ji)可(ke)(ke)采用雙滾(gun)筒(tong)(tong)(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)，其特點(dian)(dian)是(shi)結構緊湊，還(huan)可(ke)(ke)增加圍(wei)包角以增加傳(chuan)動(dong)(dong)(dong)(dong)滾(gun)筒(tong)(tong)(tong)(tong)所(suo)能傳(chuan)遞(di)的牽(qian)引(yin)力。使(shi)用雙滾(gun)筒(tong)(tong)(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)時(shi)可(ke)(ke)以采用多(duo)電機(ji)分別傳(chuan)動(dong)(dong)(dong)(dong)，可(ke)(ke)以利用齒輪傳(chuan)動(dong)(dong)(dong)(dong)裝置(zhi)使(shi)兩滾(gun)筒(tong)(tong)(tong)(tong)同速運轉。如雙滾(gun)筒(tong)(tong)(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)仍不需(xu)要(yao)(yao)牽(qian)引(yin)力需(xu)要(yao)(yao)，可(ke)(ke)采用多(duo)點(dian)(dian)驅動(dong)(dong)(dong)(dong)方式。
