Feem ntau, cov iav iav yog sib sau ua ke hu ua kis tau tus mob. Qhov laj thawj ntawm cov iav iav hnav yog:
Cov iav iav feem ntau ua haujlwm nyob rau hauv kev kub ceev, siab load, ceev thiab load. Ntxiv nrog rau kev hnav ib txwm, lub iav tseem yuav ua rau lub iav poob siab vim qhov tsis zoo ntawm lub lubricating zoo, lubrication tsis zoo, kev ua haujlwm tsis zoo, kev ua haujlwm tsis zoo ntawm cov iav sib dhos ntawm ib leeg thaum kho. Tos, lawv yuav ua kom lub cev hnav thiab kev puas tsuaj ntawm cov iav. Tsis tas li ntawd, kev hnav ntawm lwm qhov chaw lossis lwm qhov ntawm lub iav (xws li hnav ntawm lub paj zawj, cov kabmob, cov ntawv cog lus axis hauv lub iav qhov), qhov deformation (xws li kub taub hau lossis deformation ntawm lub rooj zaum ntawm cov kabmob. Lub rooj zaum ntawm lub plhaub kis tau tus mob, lub paj sib txuas curvature, thiab lwm yam), cov cuab yeej clutch), cov khoom siv clutch) Los yog kev sib dhos ntawm cov ncej sib kis tsis raug, thiab qee qhov tsis xws luag hauv kev tsim khoom (xws li txheej tsis sib xws carburizing, iav ua kom sov. , thiab lwm yam) tseem yuav ua kom nrawm ntawm lub iav.
Iav cia siab rau nws tus kheej qhov loj me thiab cov khoom siv lub zog los tiv thaiv cov khoom siv sab nraud, uas yuav tsum muaj cov khoom siv kom muaj zog toughness thiab abrasion tsis kam. Vim yog qhov nyuaj ntawm cov iav thiab cov iav siab qhov tseeb, cov khoom siv kuj yuav tsum muaj cov txheej txheem zoo.
Cov khoom siv feem ntau siv rau iav iav yog forging steel
