  传送控(kong)制滚筒的(de)(de)生(sheng)产(chan)方式主要(yao)(yao)有辊体(ti)初车、初校(xiao)静平衡、轴头(tou)过盈(ying)装配进行(xing)焊接、精车和精校(xiao)动平衡等工(gong)序主要(yao)(yao)组(zu)成。若对行(xing)为以及(ji)公差如圆(yuan)(yuan)度(du)、圆(yuan)(yuan)柱度(du)和直线度(du)等要(yao)(yao)求(qiu)在(zai)0.2mm以下的(de)(de),则(ze)在(zai)精车后需要(yao)(yao)上外圆(yuan)(yuan)磨床(chuang)或(huo)轧辊使用磨床(chuang)选择磨削技术(shu)加工(gong)。对表面具有硬(ying)度(du)有要(yao)(yao)求(qiu)的(de)(de),则(ze)需要(yao)(yao)不(bu)断增加不(bu)同热(re)处(chu)理工(gong)艺(yi)工(gong)序。

  传送滚筒成型后,出(chu)于防锈(xiu)防腐、耐磨和(he)支撑的需(xu)要(yao),还需(xu)要(yao)表面处理或包覆如(ru)喷漆(qi)、镀锌、TEFLON喷涂(tu)、包橡胶、镀铬、陶瓷喷涂(tu)和(he)氧(yang)化等工序。

按尺寸(cun)分类,有大如(ru)纸机械滚筒(tong)(长度可达(da)10米(mi)以上,直径(jing)1500mm以上),有小如(ru)自动流水线带式输(shu)送机为平(ping)辊(一般在1米(mi)以内(nei))程度,直径(jing)也为mm159..

  滚筒的选择

  1、滚(gun)筒的长(zhang)度选择:

  不同时间宽(kuan)度的货(huo)物应选适合进行(xing)宽(kuan)度的滚筒(tong),一般这种情况下(xia)可以采用(yong)“输送物+50mm”。

2.滚筒壁厚及(ji)轴(zhou)径的选择:

根据(ju)平均(jun)分配给接触滚筒(tong)的(de)(de)输送机的(de)(de)重量,计算每个滚筒(tong)所需的(de)(de)载(zai)荷,从而确定滚筒(tong)的(de)(de)壁厚(hou)和轴径。

  3、滚筒(tong)材料(liao)及材料(liao)表面进行处(chu)理 :

根据不同的输送环境,确(que)定辊筒使用的材料和表(biao)面(mian)处理(碳(tan)钢镀锌(xin),不锈钢,黑色或涂层)..

  4、选择进行传送滚(gun)筒的(de)安装(zhuang)工(gong)作方式 :

  根据企(qi)业(ye)整体设(she)计输送机的具体工作(zuo)要求(qiu),选择一个滚筒的安装管理方式(shi): 弹簧(huang)压入式(shi), 内牙轴式(shi), 全扁榫式(shi), 通轴销孔(kong)式(shi)等。

对于(yu)弯管机(ji)的锥形滚筒,辊宽和锥度取决于(yu)货(huo)物的大小和转弯半径(jing)。

  滚筒(tong)(tong)(tong)材质选择:碳钢(gang)镀锌、碳钢(gang)镀铬(ge)、碳钢(gang)包胶、铝合(he)金(jin)、不锈钢(gang)、ABS等(deng)。辊(gun)(gun)筒(tong)(tong)(tong)类(lei)型(xing)选择:无动力辊(gun)(gun)筒(tong)(tong)(tong)、传送滚筒(tong)(tong)(tong)、双链(lian)辊(gun)(gun)筒(tong)(tong)(tong)、“O”带辊(gun)(gun)筒(tong)(tong)(tong)、锥形辊(gun)(gun)筒(tong)(tong)(tong)、槽(cao)型(xing)辊(gun)(gun)筒(tong)(tong)(tong)。辊(gun)(gun)筒(tong)(tong)(tong)固定方式:弹簧压入式、内(nei)牙(ya)轴(zhou)式、全(quan)扁榫式、通轴(zhou)销孔式。
