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)(chuan)動(dong)(dong)(dong)(dong)滾筒是帶式(shi)輸送機(ji)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)力(li)(li)的(de)主要(yao)部件(jian)。作為(wei)單(dan)點驅動(dong)(dong)(dong)(dong)方式(shi)來講，可(ke)分成單(dan)滾筒傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)及雙(shuang)(shuang)(shuang)滾筒傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)。單(dan)滾筒傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)多用于(yu)功率(lv)(lv)不太大的(de)輸送機(ji)上，功率(lv)(lv)較(jiao)大的(de)輸送機(ji)可(ke)采(cai)用雙(shuang)(shuang)(shuang)滾筒傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，其特點是結構緊(jin)湊(cou)，還可(ke)增(zeng)(zeng)加圍包角(jiao)以(yi)(yi)增(zeng)(zeng)加傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)滾筒所能傳(chuan)(chuan)(chuan)遞的(de)牽引力(li)(li)。使用雙(shuang)(shuang)(shuang)滾筒傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)時可(ke)以(yi)(yi)采(cai)用多電機(ji)分別傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，可(ke)以(yi)(yi)利用齒輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)裝置使兩滾筒同速運(yun)轉。如雙(shuang)(shuang)(shuang)滾筒傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)仍不需(xu)要(yao)牽引力(li)(li)需(xu)要(yao)，可(ke)采(cai)用多點驅動(dong)(dong)(dong)(dong)方式(shi)。
