改(gai)向滾筒(tong)的特點(dian)：改(gai)向滾筒(tong)具有(you)結(jie)構緊湊、重量(liang)輕(qing)、占用少(shao)、性能、外(wai)型美觀、使用方便、在粉塵大、潮濕泥濘等惡劣條件下仍能正(zheng)常工作的特點(dian)。

改向滾筒又叫(jiao)導向滾(gun)(gun)筒，是常見的(de)皮帶輸(shu)(shu)送(song)機(ji)關鍵(jian)部件(jian)，主(zhu)要用于(yu)改變(bian)輸(shu)(shu)送(song)帶的(de)運行方向或(huo)壓緊輸(shu)(shu)送(song)帶使其增大與(yu)傳動滾(gun)(gun)筒的(de)包角。

改向滾筒適(shi)用(yong)(yong)于(yu)(yu)輸(shu)送(song)機械，主(zhu)要用(yong)(yong)于(yu)(yu)冶金、礦山、港口碼頭、化(hua)工醫藥、水泥建材、鋼鐵、煤礦等，是各種帶式輸(shu)送(song)機的驅動裝置(zhi)。

改(gai)(gai)向(xiang)(xiang)滾(gun)(gun)筒(tong)(tong)(tong)的(de)(de)(de)(de)結構(gou)：改(gai)(gai)向(xiang)(xiang)滾(gun)(gun)筒(tong)(tong)(tong)主要在皮(pi)(pi)帶運動(dong)的(de)(de)(de)(de)下(xia)方(fang)，如皮(pi)(pi)帶運送方(fang)向(xiang)(xiang)為(wei)左，那么改(gai)(gai)向(xiang)(xiang)滾(gun)(gun)筒(tong)(tong)(tong)在皮(pi)(pi)帶機(ji)的(de)(de)(de)(de)右(you)側，主要結構(gou)為(wei)軸(zhou)承和(he)(he)(he)鋼筒(tong)(tong)(tong)，傳(chuan)(chuan)動(dong)滾(gun)(gun)筒(tong)(tong)(tong)是(shi)(shi)皮(pi)(pi)帶機(ji)的(de)(de)(de)(de)主動(dong)輪，從兩者之間的(de)(de)(de)(de)關系來說就(jiu)好比自行車兩個車輪，后輪就(jiu)是(shi)(shi)傳(chuan)(chuan)動(dong)滾(gun)(gun)筒(tong)(tong)(tong)，前(qian)輪是(shi)(shi)改(gai)(gai)向(xiang)(xiang)滾(gun)(gun)筒(tong)(tong)(tong)；改(gai)(gai)向(xiang)(xiang)滾(gun)(gun)筒(tong)(tong)(tong)和(he)(he)(he)傳(chuan)(chuan)動(dong)滾(gun)(gun)筒(tong)(tong)(tong)在結構(gou)上是(shi)(shi)沒有區別的(de)(de)(de)(de)，都是(shi)(shi)由(you)主軸(zhou)滾(gun)(gun)筒(tong)(tong)(tong)軸(zhou)承及軸(zhou)承室(shi)組成傳(chuan)(chuan)動(dong)滾(gun)(gun)筒(tong)(tong)(tong)分主傳(chuan)(chuan)動(dong)和(he)(he)(he)從動(dong)兩種(zhong)。
