Nuts ni gaw jak rung matut mahkai lam hta ra kadawn ai n-gun rawng ai ni rai nga ai. Shanhte hpe hkrak jai lang ai gaw, arung arai ni a shimlum lam, ngang grin ai lam, daw jau ai prat hpe hkrak hkra machyi shangun ai. Tatut hta, n-gu ni hpe lata la ai, jung da ai, gram lajang ai lam ni gaw, kam mai ai matut mahkai lam ni hpe hkam la lu na matu hte hkrat sum chye ai lam ni hpe koi lu na matu, hpaji masa lam ni hpe hkan sa ra ai. Ndai laika hta nut lang ai lam, covering lata ai lam, jung ai lam, anti{3}} yawng hpe gram lajang ai lam ni hpe hkrak tup tsun dan na re.
1. Nut lata la ai lam
Nut lata ai lam hta, matut mahkai lam, lit ra ai lam, bungli galaw ai makau grup yin zawn re ai lam ni hpe hkrak tup myit yu ra ai. Shawng nnan, bolt masat masa ni hte bung ai nut hpe lata u, thread size (ga shadawn, M8, M10) hte n-gun atsam madang (ga shadawn, 8.8, 10.9) hpe hkan sa na matu. Lahkawng, bungli galaw ai masa amyu myu a matu specialized nut ni hpe lata la u:
High{0}}tress bungli galaw ai masa: N-gun hpe garan gachyan na matu, n-gun ja ai alloy n-gun hte hka shin jak ni hpe lang u.
Vibration makau grup yin: anti- n-gun yawm ai n-gun ni hpe ra sharawng ai (nylon insert nuts (sh) lock nuts zawn re ai) shing nrai spring washer ni hpe bang u.
Hkum hkrang n-gun n rawng ai shara ni: N-gun n rawng ai n-gang n-gun (304 or 316 zawn re ai) shing nrai zinc-tted (sh) Dacromet- ni tsi lajang ai nuts ni hpe grau kaja ai n-gun n-gun hpe ninghkap lu na matu lang u.
Bai nna, nut a n-gun gaw, n-gun n rawng ai majaw, thread strip (sh) n hkum tsup ai preload hpe koi lu na matu, bolt threading galu ai hte maren rai ra ai.
II. Nut Installation hpaji hparat ni
Nut a hkrak ai magam bungli hpe hkam la lu na matu, hkrak ai hku jung ai ladat ni gaw ahkyak nga ai. Lahta na gaw ahkyak ai operating point ni rai nga ai:
Preload Control: torque wrench hpe lang nna, n-gup hpe n-gun jaw da ai manu de n-gun dat nna, n-gup n-ga n-ga ai (dai gaw thread hpe galai shai shangun chye ai) shing nrai, n-gup n-ga n-ga ai (dai gaw n-gun yawm mat nna hkrat sum chye ai) hpe koi u. Madung hpaga lam madang ni gaw torque reference manu dan ai lam ni hpe jaw ya ai; ga shadawn, M10 bolt a matu hpaji jaw da ai torque gaw 40-60 N·m re.
Diagonal Tightening Sequence: Multi{0}}nut matut mahkai ai lam (fralangs zawn re ai) a matu, n-gun hpe n-gun langai sha garan ginhka lu na matu hte n-gun n-gun hpe n-gun n-gun hpe pat shingdang lu na matu, diagonal order hku nna n-gun hpe n-gun dat dat ai.
Lubrication Aid: Hka htung (molybdenum disulfide zawn re ai) n-gun n law ai (molybdenum disulfide zawn re ai) hpe n-gun n law ai hku jai lang ai gaw, n-gun ja ai torque hpe shayawm ya lu nna, n-gun n-gun hpe shayawm ya lu ai.
Mixing arung arai ni hpe koi u: Electrochemical n-gun n-gun n-rawng hkra, n bung ai arung arai ni hpe lang ai hpe koi u.
III. Anti- hpe hpaw ya ai ladat ni
Nut loosening gaw jak rung n kaja ai lam byin shangun ai lam langai rai nna, anti- hpe n-gun jaw ai ladat ni ra ai:
Mechanical anti-loosening: Nut hpe ngang ngang jum da na matu, n-gup magap hpe n-gun ja hkra galaw na matu, n-gup magap hpe makawp maga na matu, n-gup magap hpe n-gun ja hkra galaw u.
Friction anti-loosening: Nut lahkawng lang nna (primary nut + secondary nut) shing nrai spring washer ni hpe lang nna, n-gun n-gun hpe jat ya ai.
Antich anti-loosening: Nut hpe makawp maga na matu, shara hpe welding, riveting, shing nrai, adhesive (Lectite zawn re ai) ni hpe lang u, raitim, hpang na gram lajang na matu, bungli galaw lu na matu galaw na matu.
Special nuts: Ga shadawn ni hta nylon lock nuts (nylon ring hte n-gang ni hpe n-gup magap hte shinggrup da ai) shing nrai Tang a n-gup (dai hpe eccentric structure hte self{0}}lock) lawm ai.
IV. Maintenance hte galai shai ai hpaji jaw ga ni
Nut ni a n-gun ja ai masa hpe ayan jep yu ai gaw, hkala nba hpe pat shingdang na matu ahkyak ai lam rai nga ai:
Periodic Retightening: Shawng nnan na jak rung bungli galaw ai aten hta (sh) ayan na shingjawng ai masa ni hta, nut preload hpe aten kadun laman (ga shadawn, hkying hkum 50-100) hta bai gram lajang ra ai.
Wear Inspection: Thread stripping, nut corner bu hpun ai, shing nrai, hka shin ai lam hpe mu yang, kalang ta galai ra ai.
Disassembly Pressures: Rusted nuts hpe n-gun n-gun hte hparan ai majaw, n-gun n-gun ni hpe hkra machyi hkra, hkra machyi ai wrench (sh) pipe wrench hte n shaw kau shi yang, n-gun n rawng ai sau ni hpe n-gun n rawng hkra galaw mai ai.
Daw dan lam
Kaji ai, nuts ni gaw jak rung ni hta ahkyak ai daw ni rai nga ai. Nsen hpe lata ai, jung da ai, anti{1}}lu hpaw ai ladat ni gaw, jak rung ni a kam hpa mai ai lam hpe shatsaw ya ai sha n-ga, shi a magam bungli prat hpe mung jat ya ai. Kaja wa jai lang ai hta, bungli galaw ai masa ni hpe madung tawn nna, n-gun rawng ai galai shai lam ni hpe galaw ra ai, nut shagu gaw shi a kaja dik ai bungli galaw ai lam hta galaw lu na matu, hpaga lam a madang ni hpe ngang ngang kang kang hkan sa ra ai.
