TD75型带(dai)式输送(song)机的(de)特点

一、       胶(jiao)带输送机的(de)牵(qian)引力(li)是通过(guo)传(chuan)动滚筒(tong)(tong)与胶(jiao)带之间(jian)的(de)摩擦(ca)力(li)来传(chuan)递的(de)，因此必(bi)须将胶(jiao)带用拉紧装置拉紧，使胶(jiao)带在传(chuan)筒(tong)(tong)滚筒(tong)(tong)分离处(chu)具有一定的(de)初张(zhang)力(li)。

二(er)、       胶(jiao)(jiao)(jiao)带(dai)与货载一起在(zai)托辊(gun)上运(yun)(yun)(yun)行(xing)(xing)。胶(jiao)(jiao)(jiao)带(dai)既是牵(qian)引机(ji)(ji)构，又是承(cheng)载机(ji)(ji)构，货载与胶(jiao)(jiao)(jiao)带(dai)之(zhi)间没有相对运(yun)(yun)(yun)动(dong)，消(xiao)除了(le)运(yun)(yun)(yun)行(xing)(xing)中胶(jiao)(jiao)(jiao)带(dai)与货载的(de)摩擦阻力(li)(li)(li)。由于托辊(gun)内装有滚(gun)(gun)动(dong)轴承(cheng)，胶(jiao)(jiao)(jiao)带(dai)与托辊(gun)之(zhi)间是滚(gun)(gun)动(dong)摩擦，因此(ci)运(yun)(yun)(yun)行(xing)(xing)阻力(li)(li)(li)大大减(jian)小，从而(er)减(jian)少了(le)功率的(de)消(xiao)耗，增大了(le)运(yun)(yun)(yun)输距离(li)。对于一台胶(jiao)(jiao)(jiao)带(dai)输送(song)(song)机(ji)(ji)，其(qi)牵(qian)引力(li)(li)(li)传(chuan)递能力(li)(li)(li)的(de)大小，决定于胶(jiao)(jiao)(jiao)带(dai)的(de)张力(li)(li)(li)、胶(jiao)(jiao)(jiao)带(dai)在(zai)传(chuan)动(dong)滚(gun)(gun)筒(tong)上的(de)围包角和(he)胶(jiao)(jiao)(jiao)带(dai)与传(chuan)动(dong)滚(gun)(gun)筒(tong)之(zhi)间的(de)摩擦系数。要保证胶(jiao)(jiao)(jiao)带(dai)输送(song)(song)机(ji)(ji)的(de)胶(jiao)(jiao)(jiao)带(dai)在(zai)传(chuan)动(dong)滚(gun)(gun)筒(tong)上不(bu)(bu)打滑，正(zheng)常运(yun)(yun)(yun)行(xing)(xing)，在(zai)生产实践(jian)中要根据不(bu)(bu)同情(qing)况采(cai)取相应的(de)措(cuo)施。提高牵(qian)引力(li)(li)(li)的(de)传(chuan)递能力(li)(li)(li)可从以下几方(fang)面入手：1、增大(da)拉紧力(li)(初张力(li))。胶(jiao)(jiao)带输送(song)机(ji)在运行中，胶(jiao)(jiao)带要(yao)伸长，造成(cheng)牵引(yin)力(li)下降，所以(yi)要(yao)根据情况，利(li)用(yong)拉紧装置适当地将胶(jiao)(jiao)带拉紧，增大(da)胶(jiao)(jiao)带张力(li)，以(yi)提(ti)高(gao)牵引(yin)力(li)。2、增大(da)摩(mo)擦系数(shu)。其具体措施是：保护好传动滚(gun)筒(tong)上覆盖的木衬或(huo)橡(xiang)胶(jiao)(jiao)等衬垫(dian)，以(yi)增大(da)摩(mo)擦系数(shu)，另一方面要(yao)少出水煤(mei)，预防摩(mo)擦系数(shu)减少。3、增加围包角。井下胶(jiao)(jiao)带输送(song)机(ji)由于工作条件差，所需牵引(yin)力(li)大(da)，故多采用(yong)双滚(gun)筒(tong)传动，以(yi)增大(da)围包角。
