岷縣四輪一帶|中特重工(在線咨詢)|旋挖鉆四輪一帶：

鏈輪(lun)(lun)(lun)是帶嵌齒(chi)式(shi)扣鏈齒(chi)的輪(lun)(lun)(lun)子(zi)，用以與節鏈環或纜索上節距準確的塊體相(xiang)嚙合(he) ，一(yi)(yi)種實心或帶輻條的齒(chi)輪(lun)(lun)(lun)，與（滾子(zi)）鏈嚙合(he)以傳遞運動。鏈輪(lun)(lun)(lun)材料應保證輪(lun)(lun)(lun)齒(chi)有足夠的強度(du)(du)和耐磨性，故鏈輪(lun)(lun)(lun)齒(chi)面(mian)一(yi)(yi)般都經(jing)過熱(re)處理，使之達到一(yi)(yi)定硬(ying)度(du)(du)。

鏈(lian)(lian)輪(lun)(lun)的(de)齒形鏈(lian)(lian)輪(lun)(lun)結構鏈(lian)(lian)輪(lun)(lun)齒形必須保證鏈(lian)(lian)節能平(ping)穩自如地進入和退出嚙合(he)，盡量減(jian)少嚙合(he)時的(de)鏈(lian)(lian)節的(de)沖擊和接觸應力，而且要易(yi)于加工。

常用的鏈輪端面齒形見圖1。它是由三段圓弧aa、ab、cd和一段直線bc構成，簡稱三圓弧-直線齒形。齒形用標準刀具加工，在鏈輪工作圖上不必繪制端面齒形，只需在圖上注明'齒形按3RGB1244-85規定制造'即可，但應繪制鏈輪的軸面齒形，見圖2，其尺寸參閱有關設計手冊。參數計算前面已經提到，攤鋪機四輪一帶，不做重復敘述！

履(lv)(lv)帶：履(lv)(lv)帶主要由履(lv)(lv)帶板(ban)(ban)(ban)(ban)(ban)(ban)和鏈軌(gui)節(jie)組成，履(lv)(lv)帶板(ban)(ban)(ban)(ban)(ban)(ban)分為加(jia)(jia)強(qiang)板(ban)(ban)(ban)(ban)(ban)(ban)、標準(zhun)板(ban)(ban)(ban)(ban)(ban)(ban)和加(jia)(jia)長板(ban)(ban)(ban)(ban)(ban)(ban)。加(jia)(jia)強(qiang)板(ban)(ban)(ban)(ban)(ban)(ban)主要應用(yong)于礦山(shan)工(gong)況，標準(zhun)板(ban)(ban)(ban)(ban)(ban)(ban)用(yong)于土方工(gong)況，加(jia)(jia)長板(ban)(ban)(ban)(ban)(ban)(ban)用(yong)于濕地(di)(di)工(gong)況。礦山(shan)上對(dui)履(lv)(lv)帶板(ban)(ban)(ban)(ban)(ban)(ban)的(de)磨損(sun)嚴重，行(xing)走時碎石(shi)有(you)時會(hui)卡(ka)在兩塊(kuai)板(ban)(ban)(ban)(ban)(ban)(ban)之間(jian)的(de)縫隙中，當轉至與地(di)(di)面接觸時就會(hui)對(dui)兩塊(kuai)板(ban)(ban)(ban)(ban)(ban)(ban)產生擠壓，履(lv)(lv)帶板(ban)(ban)(ban)(ban)(ban)(ban)就容易(yi)發生彎(wan)曲(qu)變(bian)形(xing)，長時間(jian)行(xing)走也(ye)會(hui)使(shi)履(lv)(lv)帶板(ban)(ban)(ban)(ban)(ban)(ban)螺栓(shuan)固定處出現開裂問題。鏈軌(gui)節(jie)是與驅動齒(chi)(chi)圈接觸有(you)齒(chi)(chi)圈帶動進(jin)行(xing)旋轉。履(lv)(lv)帶漲緊度過緊會(hui)造成鏈軌(gui)節(jie)、齒(chi)(chi)圈和引導輪早期磨損(sun)。

漲緊度(du)的(de)測量(liang)就(jiu)是(shi)將挖(wa)掘機(ji)(ji)停(ting)放在平(ping)整地(di)(di)面(mian)，岷(min)縣四(si)(si)(si)輪(lun)(lun)(lun)一(yi)(yi)帶(dai)，使用平(ping)直(zhi)的(de)長桿放在驅動(dong)齒或(huo)引導輪(lun)(lun)(lun)與托(tuo)鏈輪(lun)(lun)(lun)之(zhi)間(jian)(jian)的(de)履(lv)帶(dai)板(ban)上，測量(liang)履(lv)帶(dai)板(ban)到(dao)長桿之(zhi)間(jian)(jian)的(de)垂直(zhi)距離，旋挖(wa)鉆(zhan)四(si)(si)(si)輪(lun)(lun)(lun)一(yi)(yi)帶(dai)，一(yi)(yi)般在15－30mm之(zhi)間(jian)(jian)；還(huan)有一(yi)(yi)種方法就(jiu)是(shi)將一(yi)(yi)側(ce)履(lv)帶(dai)支起(qi)，測量(liang)履(lv)帶(dai)板(ban)到(dao)X架之(zhi)間(jian)(jian)的(de)垂直(zhi)距離，數值一(yi)(yi)般為320－340mm之(zhi)間(jian)(jian)。根據具體工況可做適(shi)當調整，強(qiang)夯機(ji)(ji)四(si)(si)(si)輪(lun)(lun)(lun)一(yi)(yi)帶(dai)，如在礦山，濕地(di)(di)作業可在20－30mm，340－380mm，沙地(di)(di)或(huo)冰雪路(lu)面(mian)可大(da)于(yu)30，380mm。
