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)(dong)(dong)滾(gun)(gun)(gun)筒(tong)(tong)是(shi)(shi)帶式(shi)輸送(song)機傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)(dong)力(li)的主要部件。作為單(dan)點(dian)驅(qu)動(dong)(dong)(dong)(dong)(dong)方式(shi)來講，可(ke)分成單(dan)滾(gun)(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)及(ji)雙(shuang)滾(gun)(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)。單(dan)滾(gun)(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)多用于功率(lv)不太大的輸送(song)機上，功率(lv)較大的輸送(song)機可(ke)采(cai)用雙(shuang)滾(gun)(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，其特點(dian)是(shi)(shi)結構(gou)緊湊，還可(ke)增(zeng)加圍包(bao)角(jiao)以(yi)增(zeng)加傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)滾(gun)(gun)(gun)筒(tong)(tong)所能傳(chuan)(chuan)遞的牽引(yin)力(li)。使(shi)用雙(shuang)滾(gun)(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)時可(ke)以(yi)采(cai)用多電機分別傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，可(ke)以(yi)利用齒輪傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)裝置使(shi)兩滾(gun)(gun)(gun)筒(tong)(tong)同速運(yun)轉。如雙(shuang)滾(gun)(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)仍不需要牽引(yin)力(li)需要，可(ke)采(cai)用多點(dian)驅(qu)動(dong)(dong)(dong)(dong)(dong)方式(shi)。
