 皮帶是輸送(song)機與物料的(de)接(jie)觸部分，根(gen)據不同的(de)情況(kuang)，使用的(de)皮帶也各不相同。

輸送(song)機上常用(yong)的皮(pi)帶(dai)有以下(xia)幾種：耐(nai)熱輸送(song)帶(dai)、耐(nai)寒輸送(song)帶(dai)、耐(nai)酸堿輸送(song)帶(dai)、耐(nai)油(you)輸送(song)帶(dai)、食品極輸送(song)帶(dai)等(deng)品種。

皮帶輸送機(ji)的(de)工作原理是什么

帶式(shi)輸(shu)送(song)機主要(yao)由兩個端點滾筒(tong)及緊套其(qi)上的閉(bi)合輸(shu)送(song)帶組成(cheng)。帶動輸(shu)送(song)帶轉動的滾筒(tong)稱為(wei)驅動滾筒(tong)（傳動滾筒(tong)）；

另(ling)一個僅(jin)在于(yu)改變輸送(song)帶(dai)運(yun)動(dong)(dong)(dong)方向(xiang)的(de)滾(gun)(gun)(gun)筒(tong)(tong)(tong)稱(cheng)為改向(xiang)滾(gun)(gun)(gun)筒(tong)(tong)(tong)。驅動(dong)(dong)(dong)滾(gun)(gun)(gun)筒(tong)(tong)(tong)由電動(dong)(dong)(dong)機(ji)通過減(jian)速(su)器驅動(dong)(dong)(dong)，輸送(song)帶(dai)依(yi)靠(kao)驅動(dong)(dong)(dong)滾(gun)(gun)(gun)筒(tong)(tong)(tong)與(yu)輸送(song)帶(dai)之間(jian)的(de)摩(mo)擦(ca)力(li)拖動(dong)(dong)(dong)。驅動(dong)(dong)(dong)滾(gun)(gun)(gun)筒(tong)(tong)(tong)一般(ban)都(dou)裝在卸(xie)料端，以增大(da)牽引力(li)，有利于(yu)拖動(dong)(dong)(dong)。物(wu)料由喂料端喂入(ru)，落(luo)在轉動(dong)(dong)(dong)的(de)輸送(song)帶(dai)上(shang)，依(yi)靠(kao)輸送(song)帶(dai)摩(mo)擦(ca)帶(dai)動(dong)(dong)(dong)運(yun)送(song)到(dao)卸(xie)料端卸(xie)出。

帶(dai)式輸(shu)送機主(zhu)要特點是機身可(ke)(ke)以(yi)很(hen)方便的(de)伸縮(suo)，設(she)有(you)儲帶(dai)倉，機尾(wei)可(ke)(ke)隨采煤工作(zuo)面的(de)推進伸長或縮(suo)短，結構緊湊，可(ke)(ke)不設(she)基礎，直接在巷道底板上(shang)鋪設(she)，機架輕巧，拆裝十分方便。

當輸送(song)能(neng)力(li)和運距(ju)較大時，可(ke)配中間驅動(dong)裝置來滿足要求。根據輸送(song)工藝的(de)要求，可(ke)以單機(ji)輸送(song)，也(ye)可(ke)多機(ji)組合成水平或傾(qing)斜(xie)的(de)運輸系(xi)統(tong)來輸送(song)物(wu)料。

帶式輸送機(ji)廣(guang)泛地應用(yong)在冶(ye)金、煤炭、交(jiao)通、水(shui)電、化工等(deng)部(bu)門(men)，是因(yin)為它具有(you)輸送量大、結構簡單、維(wei)修(xiu)方便、成本低、通用(yong)性(xing)強等(deng)優(you)點。
