Lub neej ntawm lub iav yog nyob ntawm ntau yam, nrog rau cov khoom siv zoo, kev ua haujlwm, kev saib xyuas, thiab lub peev xwm thauj khoom. Ntawm no yog ib qho kev tawg ntawm cov yam tseem ceeb cuam tshuam rau iav lifespan:
1. Khoom siv & Kev tsim khoom zoo
High-quality steel alloys (xws li, hardened 4140, 4340) kav ntev dua li cov hlau pheej yig dua.
Kev kho cua sov (cov ntaub ntawv hardening, carburizing, nitriding) txhim kho kev hnav tsis kam.
Precision machining (sib tsoo, honing) txo kev sib txhuam thiab txuas lub neej.
2. Cov xwm txheej ua haujlwm
Load: Ntau dhau los yog poob siab loads ceev hnav.
Ceev: Siab RPM nce cua sov thiab qaug zog.
Lubrication: Lub lubrication tsis zoo los yog paug ua rau lub neej luv luv.
Ib puag ncig: Plua plav, ya raws, thiab cov tshuaj corrosive degrade gears sai dua.
3. Kev tu thiab tiv thaiv hnav
Kev hloov roj tsis tu ncua thiab kev tswj cov kab mob sib kis.
Kev sib raug zoo thiab nruj (rau cov tsheb ciav hlau thiab cov hlua).
Saib xyuas rau pitting, spalling, los yog hniav hnav.
4. Hom iav Lifespans
Lub zog muaj zog (kho tau zoo): 20,000-50,000 teev (~ 5-15 xyoos).
Automotive kis tau tus mob: 150,000–300,000 mais (nyob ntawm kev tsav tsheb).
Heavy machinery / off-road: 10,000-30,000 teev (yuav muaj kev ntxhov siab heev).
Cheap / low-quality gears: Tej zaum yuav poob hauv <5,000 teev nyob rau hauv kev siv hnyav.
5. Hom kev ua tsis tiav
Hnav: maj mam poob vim kev sib txhuam.
Pitting: Ntog qaug zog los ntawm kev ntxhov siab dua.
Cov hniav tawg: Tshaj dhau los yog cov khoom siv tsis raug.
Scoring: Lub lubrication tsis zoo ua rau kev sib cuag hlau-rau-hlau.
Yuav Ua Li Cas Ntxiv Gear Life?
Siv cov roj nplua nyeem zoo thiab hloov tsis tu ncua.
Tsis txhob overloading thiab misalignment.
Ua kev soj ntsuam kev vibration thiab saib xyuas hnav.
Hloov cov iav ua ntej muaj kev puas tsuaj loj (xws li suab nrov txawv txav, kev co).
