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)(dong)滾(gun)(gun)筒(tong)(tong)(tong)是帶式輸送機(ji)(ji)傳(chuan)(chuan)動(dong)(dong)(dong)動(dong)(dong)(dong)力的(de)主要部(bu)件。作(zuo)為(wei)單點驅動(dong)(dong)(dong)方式來講(jiang)，可分成單滾(gun)(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)動(dong)(dong)(dong)及(ji)雙(shuang)滾(gun)(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)動(dong)(dong)(dong)。單滾(gun)(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)動(dong)(dong)(dong)多(duo)用(yong)于功(gong)(gong)率不(bu)太大(da)的(de)輸送機(ji)(ji)上(shang)，功(gong)(gong)率較大(da)的(de)輸送機(ji)(ji)可采(cai)用(yong)雙(shuang)滾(gun)(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)動(dong)(dong)(dong)，其特點是結構(gou)緊湊，還可增(zeng)加圍包角以(yi)增(zeng)加傳(chuan)(chuan)動(dong)(dong)(dong)滾(gun)(gun)筒(tong)(tong)(tong)所能傳(chuan)(chuan)遞的(de)牽引(yin)(yin)力。使用(yong)雙(shuang)滾(gun)(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)動(dong)(dong)(dong)時可以(yi)采(cai)用(yong)多(duo)電機(ji)(ji)分別(bie)傳(chuan)(chuan)動(dong)(dong)(dong)，可以(yi)利用(yong)齒(chi)輪傳(chuan)(chuan)動(dong)(dong)(dong)裝置使兩滾(gun)(gun)筒(tong)(tong)(tong)同速(su)運(yun)轉。如雙(shuang)滾(gun)(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)動(dong)(dong)(dong)仍不(bu)需要牽引(yin)(yin)力需要，可采(cai)用(yong)多(duo)點驅動(dong)(dong)(dong)方式。
