Lung seng htu ai leng rim nihpaw da ai-hka htung shara ni hta bai kahtap hkra hkrat sum ai, katsi katsang re ai hte cyclic load hpe hkam sharang ra ai. Rim manghkang ni hpe aten dep chye na ai gaw, akajawng sha hkrat sum ai lam hte n myit mada ai sha mawdaw kaba hkrat sum ai lam ni hpe koi lu na matu karum ya ai. Anqiang gaw na a lung seng htu ai leng rim hpe galai ra ai hpe madun ai mu lu ai kumla ni hpe ka da ai.
1. Rim Structure ntsa kaw mu lu ai n-gun n-gun ni
Spoke ni, spoke npawt nhpang ni, hub matut mahkai ai shara ni hte rim flange ni hpe jep yu u. Ndai shara ni hta n-gun n rawng ai lam ni nga yang, rim matut nna bungli n lu galaw ai lachyum re. Dynamic load npu hta crack ni gaw loi loi hte jat wa ai. Kaji kajaw npu na n-gun n-gun ni pyi, bungli galaw ai shaloi kaba wa nna, rim daw mat na re.
2. Htani htana hkrang nsam (sh) n-gun n rawng ai
Rim flange (sh) rim hkum hkrang ntsa na n-gun n rawng ai, n-gun n rawng ai (sh) n-gun n rawng ai hkrang hpe prat tup hkrat sum ai hku hti ai. Ndai zawn re ai hkra machyi ai lam gaw rim hte tyre lapran na matut mahkai lam hpe galai shai kau ya ai. Dai gaw gat ai shaloi n bung ai lit garan ai lam hpe shabyin ya ai, tyre ni hpe lawan ladan n-gun yawm shangun ai hte rim structure ntsa stress hpe jat shangun ai. Permanent deformation byin wa ai shaloi, galai shai ra ai.
3. Bolt Hole hpe n-gun n rawng ai hte galu shangun ai
Bolt hka htung yawng hpe jep yu u. Hka htung ni gaw galu kaba wa ai, shingnip shingna byin wa ai (sh) kata jut grup yin hta grai htum mat ai hpe madun ai shaloi, bolt matut mahkai ai lam gaw ngang grin ai clamping force hpe n lu tawn da ai. Loose connection gaw bungli galaw ai shaloi loi loi hte byin wa ai. Torsion hte vibration gaw rim ting de grau nna n-gun dat ya na re. Repair galaw ai gaw, n-gun yawm mat sai bolt hka htung ni a shawng na n-gun hpe bai gram lajang ya lu na n re.
4. Grai sawng ai Corrosion (sh) Arung arai ni sum mat ai
Hka lim ai, nhprang wan hte tsi mawan ni hpe aten galu-hkap tawn da ai majaw, n-gun yawm mat ai. Rim ntsa kaw sung ai hka htung hte arung arai ni hpe shayawm kau ai majaw, npawt nhpang a akyu rawng ai cross-section hpe shayawm kau ya ai. Corrosion hka htung ni gaw sung sung shang wa ai (sh) key load-bearing shara ni hta chyam bra wa yang, rim gaw shi a hkrang shapraw da ai lit hkam lu ai atsam hpe sum mat ai.
5. Rim hte Tire matut mahkai ai shara kaw hka pru ai
Rim flange hte tire bead lapran na sealing shara kaw na nbung pru wa ai gaw rim ntsa hkra machyi ai majaw byin chye ai. Ntsa na n-gun n rawng ai, hka htung (sh) n-gun n rawng ai hpe n mai gram lajang ai shaloi, nbung n-gun matut nna pru wa na re. Rim hpe galai ra ai.
6. N jahten sharun ai chyam dinglik ai lam hku nna mu lu ai n kaja ai lam ni
Nkau kata na n kaja ai lam ni hpe myi hte n mu lu ai. NDT jep joi ai lam hta rim hkum hkrang kata makoi da ai microcracks, shrinkage cavities (sh) arung arai n matut manoi ai lam ni hpe mu lu na re. Hkamja lam jep chyoi ai shiga ni hta ahkang jaw da ai shadawn shadang hta jan nna n kaja ai lam ni nga ai hpe mu yang, rim hpe bungli kaw na shapraw kau ra ai.
7. Grai hkrat sum ai hpang hkra machyi ai lam
Dai leng gaw lung seng kaba ni hpe hkra ai (sh) grai sawng ai hku hkrat sum mat yang, tup hkrak jep yu ra ai. Mu lu ai ntsa lam n hkrat sum ai sha pyi, kata na microcracks ni byin wa chye ai. NDT gaw hkrat sum ai hpang kata na n kaja ai lam ni hpe mu ai shaloi, rim hpe galai kau u.
Masha law malawng tara jeyang shut ai lam ni
- Kaji kajaw n-gun n rawng ai hpe n sawn ai sha, mawdaw kaba hpe matut nna gat shangun u
- Weld galaw nna galu kaba ai bolt hka htung ni hpe gram lajang na matu shakut u.
- - kaw na - n lawm ai rims ni hpe matut lang un
- Nbung kaji kajaw lwi ai hpe tyre manghkang langai zawn sha galaw u
Operator ni gaw rim hpe ayan jep yu ra ai. N-gun n rawng ai, prat tup n-gun n rawng ai, galu kaba ai bolt hka htung ni, sung ai n-gun rawng ai hte NDT-hkap la ai kata na n-gun n rawng ai lam ni gaw galai shai na matu madung kumla ni rai nga ai. Ndai kumla ni pru wa ai shaloi, rim hpe kalang ta jai lang ai hpe jahkring kau u. Anqiang arung arai nin-gun ja ai-hpyen htu ai leng leng rim nihkum tsup ai jep joi ai lam ni hpe ka da ai.
