黃石四輪一帶,中特工程(優質商家),四輪一帶 市場：

履(lv)(lv)(lv)(lv)帶(dai)(dai)(dai)：履(lv)(lv)(lv)(lv)帶(dai)(dai)(dai)主要(yao)由履(lv)(lv)(lv)(lv)帶(dai)(dai)(dai)板(ban)(ban)(ban)(ban)(ban)和(he)鏈(lian)軌節組成，履(lv)(lv)(lv)(lv)帶(dai)(dai)(dai)板(ban)(ban)(ban)(ban)(ban)分為加(jia)(jia)強板(ban)(ban)(ban)(ban)(ban)、標準(zhun)板(ban)(ban)(ban)(ban)(ban)和(he)加(jia)(jia)長板(ban)(ban)(ban)(ban)(ban)。加(jia)(jia)強板(ban)(ban)(ban)(ban)(ban)主要(yao)應用于礦(kuang)山(shan)工(gong)況，標準(zhun)板(ban)(ban)(ban)(ban)(ban)用于土方工(gong)況，加(jia)(jia)長板(ban)(ban)(ban)(ban)(ban)用于濕地(di)工(gong)況。礦(kuang)山(shan)上對(dui)履(lv)(lv)(lv)(lv)帶(dai)(dai)(dai)板(ban)(ban)(ban)(ban)(ban)的磨(mo)損嚴重(zhong)，行(xing)(xing)走(zou)時(shi)(shi)碎石有時(shi)(shi)會(hui)卡在兩塊板(ban)(ban)(ban)(ban)(ban)之間的縫隙中，當轉至與地(di)面接(jie)觸時(shi)(shi)就會(hui)對(dui)兩塊板(ban)(ban)(ban)(ban)(ban)產生擠壓，履(lv)(lv)(lv)(lv)帶(dai)(dai)(dai)板(ban)(ban)(ban)(ban)(ban)就容易發生彎曲(qu)變形，長時(shi)(shi)間行(xing)(xing)走(zou)也會(hui)使履(lv)(lv)(lv)(lv)帶(dai)(dai)(dai)板(ban)(ban)(ban)(ban)(ban)螺栓固定處(chu)出現開裂問(wen)題。鏈(lian)軌節是與驅動齒圈接(jie)觸有齒圈帶(dai)(dai)(dai)動進行(xing)(xing)旋(xuan)轉。履(lv)(lv)(lv)(lv)帶(dai)(dai)(dai)漲緊度過緊會(hui)造成鏈(lian)軌節、齒圈和(he)引導輪早期磨(mo)損。

漲緊(jin)度的(de)(de)測(ce)(ce)(ce)量(liang)就(jiu)是將挖(wa)掘機停放在平(ping)整地(di)面，使用(yong)平(ping)直(zhi)(zhi)的(de)(de)長桿放在驅(qu)動齒或(huo)引導輪與托鏈輪之(zhi)間(jian)(jian)的(de)(de)履(lv)帶板上(shang)，測(ce)(ce)(ce)量(liang)履(lv)帶板到長桿之(zhi)間(jian)(jian)的(de)(de)垂直(zhi)(zhi)距離，一(yi)般在15－30mm之(zhi)間(jian)(jian)；還(huan)有一(yi)種方法就(jiu)是將一(yi)側履(lv)帶支(zhi)起，測(ce)(ce)(ce)量(liang)履(lv)帶板到X架之(zhi)間(jian)(jian)的(de)(de)垂直(zhi)(zhi)距離，數值一(yi)般為320－340mm之(zhi)間(jian)(jian)。根據具(ju)體工況可做適(shi)當調整，如在礦(kuang)山，濕(shi)地(di)作業可在20－30mm，340－380mm，沙(sha)地(di)或(huo)冰雪路面可大于30，380mm。

液(ye)壓挖(wa)掘機發動(dong)(dong)機的(de)動(dong)(dong)力通(tong)過行(xing)走(zou)馬達(da)和驅動(dong)(dong)輪傳給履帶，要求驅動(dong)(dong)輪與履帶的(de)軌鏈嚙(nie)合正確，傳動(dong)(dong)平穩，并且(qie)當履帶因銷套磨損而伸長時(shi)仍(reng)能很(hen)好的(de)嚙(nie)合。驅動(dong)(dong)輪通(tong)常位于挖(wa)掘機行(xing)走(zou)裝(zhuang)置的(de)后部。按構(gou)造可分(fen)(fen)為：整體(ti)式，分(fen)(fen)體(ti)式按節距(ju)可分(fen)(fen)為：等節距(ju)，不等節距(ju)材料：50MN，45SIMN，并使其硬度達(da)到HRC55-58

制作軸承座

　　導(dao)向(xiang)輪(lun)(lun)(lun)用耐(nai)磨合金(jin)鋼制成，從焊(han)接(jie)的(de)工(gong)藝(yi)性考慮，其(qi)軸(zhou)承(cheng)座(zuo)宜(yi)選(xuan)用45#鋼加(jia)工(gong)制作(zuo)。根據(ju)導(dao)向(xiang)輪(lun)(lun)(lun)支承(cheng)部(bu)位的(de)厚(hou)度、中(zhong)心孔(kong)可鏜削(xue)量以及7319型軸(zhou)承(cheng)的(de)外徑(jing)尺(chi)(chi)(chi)寸(cun)，確定軸(zhou)承(cheng)座(zuo)的(de)具(ju)體(ti)尺(chi)(chi)(chi)寸(cun)并(bing)(bing)進行加(jia)工(gong)制作(zuo)。具(ju)體(ti)步驟是：首(shou)先，用45#鋼加(jia)工(gong)1個外徑(jing)230 mm、內徑(jing)195 mm、長度略大(da)于導(dao)向(xiang)輪(lun)(lun)(lun)厚(hou)度的(de)鋼管(guan)；其(qi)次，將導(dao)向(xiang)輪(lun)(lun)(lun)中(zhong)心孔(kong)鏜削(xue)至φ230 mm，并(bing)(bing)使中(zhong)心孔(kong)與鋼管(guan)之(zhi)間(jian)留有0.05~0.10 mm配合間(jian)隙(xi)；再(zai)次，用普通焊(han)條將加(jia)工(gong)好的(de)鋼管(guan)取中(zhong)焊(han)接(jie)于導(dao)向(xiang)輪(lun)(lun)(lun)中(zhong)心孔(kong)中(zhong)；后，將鋼管(guan)內徑(jing)尺(chi)(chi)(chi)寸(cun)鏜削(xue)至φ200+0.10 mm（準備與7319型軸(zhou)承(cheng)外套配合），并(bing)(bing)將2個端面(mian)車削(xue)到與導(dao)向(xiang)輪(lun)(lun)(lun)寬度相等(deng)，然(ran)后車削(xue)倒角，便于下一步組裝。
