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)(gun)筒(tong)是帶式輸(shu)送機(ji)傳(chuan)動(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)力(li)的主要(yao)部件。作(zuo)為單(dan)點(dian)(dian)(dian)驅動(dong)(dong)(dong)(dong)方式來講，可(ke)分成單(dan)滾(gun)(gun)筒(tong)傳(chuan)動(dong)(dong)(dong)(dong)及雙(shuang)滾(gun)(gun)筒(tong)傳(chuan)動(dong)(dong)(dong)(dong)。單(dan)滾(gun)(gun)筒(tong)傳(chuan)動(dong)(dong)(dong)(dong)多用于(yu)功率(lv)不太大(da)的輸(shu)送機(ji)上，功率(lv)較大(da)的輸(shu)送機(ji)可(ke)采用雙(shuang)滾(gun)(gun)筒(tong)傳(chuan)動(dong)(dong)(dong)(dong)，其特點(dian)(dian)(dian)是結構緊湊(cou)，還可(ke)增(zeng)加(jia)圍包角以增(zeng)加(jia)傳(chuan)動(dong)(dong)(dong)(dong)滾(gun)(gun)筒(tong)所(suo)能傳(chuan)遞的牽引力(li)。使用雙(shuang)滾(gun)(gun)筒(tong)傳(chuan)動(dong)(dong)(dong)(dong)時可(ke)以采用多電(dian)機(ji)分別傳(chuan)動(dong)(dong)(dong)(dong)，可(ke)以利用齒輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)裝置使兩滾(gun)(gun)筒(tong)同速運轉。如雙(shuang)滾(gun)(gun)筒(tong)傳(chuan)動(dong)(dong)(dong)(dong)仍不需(xu)要(yao)牽引力(li)需(xu)要(yao)，可(ke)采用多點(dian)(dian)(dian)驅動(dong)(dong)(dong)(dong)方式。
