Peb txhua tus paub tias kom lub tsheb khiav zoo, ua ntej ntawm tag nrho nws yog inseparable ntawm lub cav, thiab lwm yam tseem ceeb heev yog lub log. Ib qho tseem ceeb tshaj plaws ntawm lub log yog lubbearing. Qhov zoo ntawm cov kabmob ncaj qha cuam tshuam rau kev ua haujlwm ntawm lub log tsheb, thiab kev tshuaj xyuas tag nrho cov kabmob yog qhov tseem ceeb tshwj xeeb.

Cov ntsiab lus tseem ceeb uas yuav tsum tau ua tib zoo saib hauv kev tshuaj xyuas qhov muag yog raws li hauv qab no:

(1) Ntau yam kab nrib pleb, xws li raw khoom tawg, forging cov kab nrib pleb, kev kho cua sov cov kab nrib pleb thiab sib tsoo cov kab nrib pleb, thiab lwm yam, cov kab nrib pleb no yuav dhau los ua lub hauv paus ntawm kev ntxhov siab thiab nthuav dav sai thaum lub sijhawm ua haujlwm ntawm cov kabmob yav tom ntej, ua rau cov kabmob. mus rupture, cuam tshuam raubearinglub neej thiab kev ua haujlwm. Kev ruaj ntseg cuam tshuam loj heev.

(2) Ntau yam kev ntiab tawm, xws li abrasions, khawb, crushes, pob, thiab lwm yam, yuav ua rau cov kabmob tsis zoo, ua rau lub nra hnyav thiab kev ntxhov siab, thiab ua rau kev sib hloov qhov tseeb thiab kev pabcuam lub neej poob qis.

(3) xeb, tawv tawv dub thiab pitting, ob lub tom kawg yog qhov tsis xws luag uas yooj yim khaws cov dej noo thiab av, thiab yooj yim rau kev loj hlob mus rau xeb. Corrosion yog ib qho ntawm cov kab mob sib kis uas ua rau kev txhim kho tsis zoo, hnav thaum ntxov thiab qaug zog, thiab xeb hnyav tuaj yeem ua rau cov bearings scrapped.

(4) Peeling thiab folding, ob qhov tsis xws luag yog ib feem ua ke nrog lub hauv paus hlau, thiab feem ntau decarburized los yog decarbonized phenomena nyob ib ncig ntawm lawv mus rau txawv degrees. Heev tsis zoo.

(5) Rau riveting lossis vuam zoo ntawm lub tawb, feem ntau saib seb lub taub hau rivet yog deviated, skewed, slack, tsis muaj nqaij los yog "ob lub qhov muag", seb qhov vuam txoj hauj lwm yog lawm, seb qhov vuam taw tes loj dhau los yog me me dhau, thiab seb qhov vuam tsis muaj zog los yog vuam ntau dhau ua rau lub caij dov yuav daig.
